Manual Overview 1.1 General Description The Intelligent High Power (iHP) series is an addition to Artesyn's existing breadth of configurable AC to DC power supply products. The iHP series offers the highest power and voltage rating in the configurable family and provides the most flexible and universal solutions for medical and industrial applications. The iHP series provides accuracy, resolution, and stability as either a programmable voltage or current source. The basic modular concept consists of an iHP rack into which iHP modules are inserted. The rack is a Power Factor corrected front-end converting worldwide standard AC input voltages into a regulated high voltage DC (HVDC) output. The pluggable modules provide an extended range of voltage and current combinations converting the HVDC input into programmable 3KW increments of output power. iHP output modules are configured into a power system by plugging the modules into one of two different standard 19" AC-HVDC racks. One rack houses up to four modules (12KW) and the other rack up to eight modules (24KW). Provisions are made for up to six racks to be connected and controlled in parallel. Safety approvals secured by Artesyn eliminate the need for an isolation transformer in medical equipment. The iHP system also has industrial safety approvals, including compliance to the SEMI F47 standard for semiconductor processing equipment. The iHP series offers developers either an analog or digital interface to their system, supporting standard communications protocols, including CANbus, Ethernet, and RS485. Digital control enables the use of Artesyn's high-level PowerPro software graphical user interface (GUI) to control and monitor all functions on one or multiple iHP systems. The PowerPro GUI also incorporates graphical script creation that allows users to write their own process control routines. The iHP series offers efficient power factor correction (PFC) and low total harmonic distortion (THD) over a wide range of loads. It uses a multi-phase continuous mode boost PFC architecture, resulting in ripple current cancellation that offers lower EMI and extends the life of electrolytic capacitors. Users can configure and customize the iHP modules to fit exact applications requirements. A qualified service personnel can configure the iHP rack for single or three phase inputs. The modules can be connected in series or parallel, while achieving accurate voltage and current sharing. Using grouping commands, modules in parallel or series can be controlled as one single output. For specific types of load applications, the iHP system can be programmed to three different compensation configurations including resistive load, capacitive load and LED load. The LED load compensation opens new applications for large horticulture farms that require high voltage for many LED strings tied in series. 1.2 Operational Overview The iHP system is designed to be configurable to meet varied design requirements. The number of configurable parameters is extensive and access to the parameters is via a computer interface instead of the front panel. Before operating the supply, it is important that communication between a computer and the supply be established and the supply operational parameters be configured for the intended application. iHP Manual 10 | P a g e iHP Owners Manual The simplest way to get started is to use the Power Pro Connect Module (PPCM) to establish a link to the supply. The PPCM allows the user to quickly establish a connection with the power supply with a Web based GUI and set up the power supply. The configuration of the supply can be set up to run autonomously when powered on, controlled via rear panel digital and analog input and outputs, or actively controlled via the PPCM. For more advanced users developing their own software control, the PPCM is not required and the supply can be directly interfaced via the users preferred standard communications protocols, including CANbus, Ethernet and RS485. 1.3 Specification Summary Tables 1-1 and Table 1-2 below summarize the 24K and 12K input parameters, followed by Table 1-3 outlining the general Module specifications Table 1-1 iHP24 Electrical Specifications Input Parameter Input range Number of phases Frequency Phase detection Max current/phase Under voltage detection Current inrush Power factor Harmonic distortion Line interruption Input leakage current Power switch Input protection Input overvoltage protection Phase imbalance Rack parallel Efficiency Standby voltage Standby regulation Standby max current iHP Manual 19" Rack 24 KW strapped as 3-phase 19" Rack 24 KW strapped as 3-phase 380/480 Vac Nominal (iHP24H3A/L) 208/240 Vac Nominal (iHP24L3A/L) 342 Vac to 528 Vac 187.5 Vac to 264 Vac (Nominal rating 380/480 Vac) (Nominal rating 208/240 Vac) 3-phase (Wye or Delta) 4 wire total (3-phase and 1 protective earth ground) 47-63 Hz Loss of phase will inhibit unit off.

The iHP system is designed for horizontal mounting. Contact customer service if other mounting orientation is desired. iHP air-cooled units should be installed in a protected environment. Exposure to corrosive or conductive material can result to damage. iHP air-cooled units should have sufficient ventilation. The front and rear surfaces of the iHP system are recommended to have a minimum clearance of 2" from any airflow blockage. The airflow is front to back with cool airflow entering the front panel and exhausting the rear panel. There is no airflow through the top and bottom of supply. No clearance is required above or below the supply and multiple supplies can be stacked without clearance requirements above or below the supply. Install in a location that will not exceed 50C operating ambient temperature. For system enclosures, the front panel (air inlet) should receive fresh air. iHP Manual 20 | P a g e iHP Owners Manual 2.3.2 Lifting Provision Warning! - 24KW iHP models require a minimum two-man lift. The iHP rack has been provided with lifting holes which can accommodate carabiners. Recommended carabiner size and location of lifting holes are shown in Figure 2-2. Figure 2-2 Lifting hole location for the power system Caution! - The front panel handles are not designed to carry the whole weight of iHP. 2.3.3 Mounting The iHP rack is designed to fit inside a 19-inch rack. Recommended rack depth is at least 33 inches from front panel to back. The front panel cannot support the weight of the supply. Use appropriate L-brackets or an equipment tray, which can support the weight of the iHP system. The iHP rack also has mounting screw holes on the side panels, which can be used for other mounting configurations. The side panel mounting holes when fully utilized are sufficient to support the weight of the rack and modules. It is designed for metric M5 screws and has 6mm maximum screw penetration. See Section 1.3.3, Figure 1-1 for the location of the mounting holes. 2.4 Inserting Modules Figure 2-3 shows how to insert the iHP modules into an iHP rack. iHP Manual 21 | P a g e iHP Owners Manual Caution! - Observe proper orientation of the module during insertion (output busbars at the bottom) to prevent damage to the module and rack connectors.

For good regulation the remote sense connections must be made after the OR-ing diode at the same point on the busbar or load. The remote sense leads should be the same length for each power supply and a twisted pair should be used for best noise immunity. The current share lines between the power supplies should be connected as shown in Figure 2-10. Figure 2-10 Blocking diode for use when connecting modules in parallel An antiparallel diode should be connected across each module's terminal to prevent sinking of current into one module when it is OFF while the others are ON. The diode should be capable of carrying the maximum current and the forward voltage (Vf) drop should be lower than what is in the table below. iHP Manual 30 | P a g e iHP Owners Manual Table 2-5 Model Min Voltage Rating (V) Min Current Rating (A) Maximum Vf Use below recommended device or its equivalent 12V 45 300 0.9V @ 160A (Tj = 125degC) IXYS: DSS 2x160-0045A (45V 2x160A) 24V 45 200 0.9V @ 160A (Tj = 125degC) IXYS: DSS 2x160-0045A (45V 2x160A) 32V 100 120 0.7V @ 80A (Tj = 125degC) STMicroelecronics: STPS160H100TV (100V 2x80A) 48V 100 120 0.7V @ 80A (Tj = 125degC) STMicroelecronics: STPS160H100TV (100V 2x80A) 80V 150 80 1.5V @ 50A (Tj = 125degC) STMicroelecronics: STTH10002TV1 (200V 2x50A) 125V 200 50 1.5V @ 50A (Tj = 125degC) STMicroelecronics: STTH10002TV1 (200V 2x50A) 200V 400 30 1.5V @ 60A (Tj = 125degC) STMicroelecronics: STTH120R04TV1 (400V 2x60A) 250V 400 30 1.5V @ 60A (Tj = 125degC) STMicroelecronics: STTH120R04TV1 (400V 2x60A) For series connection, the remote sense for each module should be connected to its output busbar instead of the output load. Figure 2-11 Antiparallel diode for use when connecting modules in series iHP Manual 31 | P a g e iHP Owners Manual Digital Communication Digital communication is necessary to setup and operate the iHP system. Digital communication will be used to: Read the configuration setting of the iHP Change the configuration setting of the iHP Voltage, current, temperature, and power reporting Status reporting SW updates for module, PFC, and ISOCOMM Available user digital communications interfaces for the iHP are CAN, RS485, and Ethernet. The connection ports are shown in Figure 3-1. Ethernet (UDP protocol), RS485 (custom RS485 protocol), and CAN (custom CAN protocol) protocol specifications are in a separate document. Communication with the iHP system is controlled via the iHP ISOCOMM (ISOlated COMMunication) section of the supply. All commands are sent to and from the iHP ISOCOMM via the digital communication link. Once a command has been sent to the iHP ISOCOMM, ISOCOMM will handle the sending of the information to the internal PFC section and installed modules. The ISOCOMM functions as a bridge between iHP internal communication and iHP external communication. Inside the iHP rack, there is an Internal Communication Bus. The installed modules, PFC (Primary Side), and ISOCOMM are all connected to this Internal Communication Bus, but are electrically isolated from each other per safety requirements. ISOCOMM manages the internal communications and external communication of the iHP. Once ISOCOMM receives a command from the user, ISOCOMM will transmit the command to the module or PFC section of the iHP. If the user needs data from a module or PFC device, the module or PFC device will transmit data to the ISOCOMM and ISOCOMM will be the one to send data to the user. Figure 3-1 12kW and 24kW ISOCOMM Section iHP Manual 32 | P a g e iHP Owners Manual 3.1 iHP Digital Communication Identifier To communicate to the iHP, the user needs to know the iHP address and the specific device inside the iHP system in which the user needs to communicate. ISOCOMM, installed modules and PFC devices function independently inside an iHP system and each device has its own device address as shown in Figure 3-2 and 3-3. Figure 3-2 24kW iHP rack internal communication architecture iHP Manual 33 | P a g e iHP Owners Manual Figure 3-3 12kW iHP rack internal communication architecture 3.1.1 iHP Address Each iHP system will have a specific address for digital communication. The address will be used to communicate from the PC/Laptop to the iHP system. The iHP address is dependent on the mode of communication. Ethernet Address - depends on the configuration of iHP. IP setting can be Static or DHCP. For Static IP, this will need to be set to an unassigned IP address by the user before integration into a system. For DHCP, the router will assign an open IP address. CAN/RS485 - CAN and RS485 communication shares the same address from 0 to 5. When using multiple iHP systems, the address will need to be set before integrating with other iHP systems to avoid address conflicts. The IP setting and CAN/RS485 address configuration settings are discussed in more detail in Section 5.1.3. iHP Manual 34 | P a g e iHP Owners Manual 3.1.2 Internal Device Address inside iHP An iHP system is composed of different independent devices (modules and PFC devices). The internal device address is used to identify the specific device or module group in which user wants to communicate. Please see below table for the Internal Device Address inside the iHP system.

All PFC devices have a specific set of commands, all module devices have a specific set of commands, and the ISOCOMM device has a specific set of commands. The PFC command list is in Appendix B.1, the module command list is in Appendix B.2, and the ISOCOMM command list is in Appendix B.3. iHP commands can be classified into four groups: iHP Manual 35 | P a g e iHP Owners Manual User Configurable Commands - Commands that can be configured based on the user operation requirements. The user configurable commands are the commands that can be read or written by the user. Notes for Module User Configurable Command: The user needs to send the save command (Using ISOCOMM command D7h) in order to retain the command on the next power-up. ISOCOMM command is required to change the module's D3h (MODULE_CONFIG), B5h (MODULE_VRISE_TIME), B6h (MODULE_IRISE_TIME). When the user sends these commands, the setting will be AutoSaved to the module and there is no need to send a separate save command. Manufacturer Commands - Commands used by the manufacturer. The user is not allowed to use these commands. Read-Only commands - Commands for iHP system reporting and fixed configuration settings. The user can only read these commands. Voltage, current, power, and temperature reporting Status reporting Fixed configuration settings Special Command - Commands that have special function in the operation of the iHP system. 3.3 Interval Between User Commands To communicate properly there should be a time interval between user commands. Table 3-2 iHP Module Mode in an iHP Rack Time Interval between User Command Ethernet RS485 CAN All iHP modules are configured as Digital Mode 20msec 100msec TBA At least one iHP module is configured as Analog Mode 50msec 100msec TBA 3.4 Ethernet Communication The iHP Ethernet connection can support up to 10/100Mbps link speed. The iHP IP setting can be configured to static IP or Dynamic Host Configuration Protocol (DHCP). By default, the Ethernet communication is set to DHCP, which requires connection with a router to assign an IP address. If a router is not being used, the iHP will not have an IP address to allow communication, so the user will need to use the LAN RESET button to set the iHP to known state, which is static IP with IP address of 192.168.2.100. iHP Manual 36 | P a g e iHP Owners Manual The iHP rack can be connected to a PC directly using the static IP setting. When using the iHP system with static IP mode, the user computer may need to have a static IP as well to communicate. Details on setting the IP configuration is discussed in Section 5.1.3. Figure 3-4 shows an example of connecting directly to the iHP system using a static IP. If the user has forgotten the Ethernet setting, the user can push the LAN RESET button to reset the Ethernet. The LAN RESET button will reset the Ethernet connection to a known state, which is static IP with the IP address of 192.168.2.100. Figure 3-4 iHP system connected directly to the PC (static IP) iHP Manual 37 | P a g e iHP Owners Manual If the user's PC/Laptop needs to connect to the iHP system and the user's network, the user should use a router (static IP or DHCP) or switch (static IP) as shown in Figure 3-5. Figure 3-5 IHP system connected using a router or switch Up to six iHP systems can be used on the same network at the same time. To communicate using a PC with multiple iHP systems, the user can use a router (static or DHCP IP) or switch (static IP) as shown in Figure 3-6. iHP Manual 38 | P a g e iHP Owners Manual Figure 3-6 Multiple iHP systems connected to PC via a router or switch The recommended equipment for communicating with the iHP system via the Ethernet are as follows: 8-pin RJ45 cable Router or Switch iHP Manual 39 | P a g e iHP Owners Manual 3.5 RS485 Communication An iHP system can support RS485 communication with below settings: Bits per seconds = 115200 Data bits = 8 Parity = None Stop bits = One Flow control = None RS485/CAN Bus Terminator or 120 terminating resistors are required at both end terminals, PC and iHP rack.

It is assumed in this section that this will be the first time the iHP rack and iHP module will be powered up after iHP rack and module was manufactured by Artesyn. 4.1.1 Initial Power-up Discussed in this section are the iHP rack and iHP module default settings when shipped from Artesyn. Configure the input and output connections to the iHP rack and iHP modules based on user requirements. Please follow Section 2 for the installation requirement. Apply input AC to the iHP rack. Note: Please follow the allowable input AC parameters located on the AC input rating label of the iHP rack. Figure 4-1 AC Input connections and AC input rating label location Upon the application of input AC, the ISOCOMM will undergo boot-up sequence. The fan will momentarily turn on at full speed and will settle down. The power LED, in the front panel, shown in Figure 4-2, will be blinking GREEN color during the boot-up sequence. After boot-up sequence, the power LED will be either steady RED (AC BAD) or steady GREEN (AC OK) depending on the AC power to the iHP rack. For a full list of LED responses, please refer to Appendix A. iHP Manual 43 | P a g e iHP Owners Manual Figure 4-2 Front Panel Power LED After about 20secs from the application of input AC, the boot-up sequence should be completed. The iHP rack will have detected the slot with installed modules and ISOCOMM will be functional. From the factory, when initially applying input AC, the iHP module outputs will not power-up by default and the user will need to press the front panel switch. The modules are shipped by Artesyn with Digital Voltage Source (DVS) configuration and the output voltage will be set to the module's nominal voltage. The iHP rack and module software configuration when shipped from Artesyn are listed on the next section. 4.1.2 iHP Module Default Settings Table 4-1 contains iHP module default settings when shipped from Artesyn.

To compensate for the voltage drops on the wire, remote sense is employed. The module has a positive return, V_SNS+ J2 Pin 1, and a negative return, V_SNS- J2 Pin 8, remotes sense to compensate for ground drops and line drops respectively. Remote sense will be able to regulate out a maximum of 200mV drop on each sense line. It is recommended for user to connect the remote sense either on the load side or to the output terminals of the modules. The connection of the remote sense signal determines the point at which the voltage will regulate. Remote sense is required to meet the regulation specification of the module. Remote sense is required during voltage source configuration. The module will protect itself if the polarity is incorrectly connected between the V_SNS+ and V_SNS- to module's output positive and negative terminal. It is recommended to use twisted and equal length wires for V_SNS+ and V_SNS- for noise immunity. For parallel module output operation, all module V_SNS+ should be star connected and all module V_SNS- should be star connected as shown by examples in Figure 4-7. Star connection is recommended to reduce the introduction of DC offset and noise to the signals. iHP Manual 54 | P a g e iHP Owners Manual Figure 4-7 Examples of star connections for remote sensing 4.2.1.2.2 External Current Sense An external shunt resistor can be connected to the iHP module. The current sensing will be transferred from the iHP module internal shunt to external shunt. The iHP module's EXT_ISENSE+ J2 Pin 3 and EXT_ISENSE- J2 Pin 9 signals are used for external current sense application. The module configuration should be changed to enable external current sense operation via ISOCOMM command module MODULE_CONFIG (D3h). iHP Manual 55 | P a g e iHP Owners Manual When using external current sense, all output current information used by the iHP module will be taken from the differential voltage across the external shunt. The information collected from external sense connections will be used for output reporting, current protection, and constant current operation. Connection of the external shunt should only be on the negative output busbar of the iHP module. The EXT_ISENSE- should be connected to the external shunt's negative output busbar side and the EXT_ISENSE+ should be connected to the external shunt's load side as shown in Figure 4-8. Figure 4-8 Location of external shunt and external shunt sense lines Table 4-9 list the required shunt resistor per iHP module.

Interconnecting the ISHARE signal of the modules in a star connection activate the active current sharing circuitry. Active current sharing is required when modules are connected in parallel. The module's ISHARE signal and D_RTN J2 Pin 4 should be star connected. This will reduce the introduction of DC offset and noise to the signals. 4.2.1.2.6 D_RTN D_RTN (J2 Pin2 and Pin7) is used for twisted pair cabling of IMON and VMON signal to reduce noise pick up. D_RTN (J2 Pin2) is used for twisted pair cabling with IMON. D_RTN (J2 Pin7) is used for twisted pair cabling with VMON. D_RTN (J2 Pin4) is used as return ground for the ISHARE signal. iHP Manual 57 | P a g e iHP Owners Manual D_RTN is internally connected to module's negative output and D_RTN is isolated from module's J1 SYS_RTN. 4.2.2 iHP Rack Communications and Interfaces The following section describes the available communication ports and protocols available on the rack to interface the rack to the user's system.

The operating mode is set by the ISOCOMM D3h command and once set remains in the mode chosen until changed by a sending a new configuration via the ISOCOMM D3h command. Digital Voltage Source (DVS) - The module operates as a voltage source. The module output voltage functions can only be controlled by sending a command using a PC or laptop. Digital Current Source (DCS) - The module operates as a current source. The module output current functions can only be controlled by sending a command using a PC or laptop. Analog Voltage Source (AVS) - The module operates as a voltage source. The module output voltage can only be controlled by inputting 0V-10V to module's 0-10VEXT_VPROG signal (module J1 connector pin1) or 0V-5V to module's 0-5VEXT_VPROG signal (module J1 connector pin2). iHP Manual 64 | P a g e iHP Owners Manual Analog Current Source (ACS) - The module operates as a current source.

A wide range of digital commands is supported. Module commands are specific to an individual module at the module level. ISOCOMM commands are higher-level system commands such as when controlling a group of modules. Many of the commands are fixed but several are user configurable. A list of the user configurable commands specific to the modules and example of the command structure is shown in Section 5.2. Definition of all the Module Commands is in Appendix B.2, Module Command. Definition of ISOCOMM Command is in Appendix B.3, ISOCOMM Command. 4.4.1 Digital Voltage Source (DVS) In this operating mode, the user has the capability to control the output voltage using digital means. A PC or laptop will be required to change the output voltage. To change to Digital Voltage Source (DVS) mode, the user needs to send below commands to ISOCOMM. Device Address ISOCOMM Command Data1 Data2 00h D3h <Module slot or Group #> 00h *Before writing to the ISOCOMM, please ensure that the ISOCOMM Command Write Protect (10h) is disabled. Where: Data1 please refer to ISOCOMM Command Table Data2 "00h" signifies Digital Voltage Source After sending ISOCOMM Command D3h, the modules will momentarily shutdown, re-initialize, and then restart. The shutdown, re-initialize, and restart process takes approximately 1.5 seconds. Since the module iHP Manual 65 | P a g e iHP Owners Manual will re-initialize, the Module Operational Command (01h) and Module Write Protect Command (10h) will be set to enable. The module output will be ON and set to nominal V out. Table 4-17 lists the status of the module command and the functionality of the commands when configuring the module to DVS mode. Table 4-16 Functional in DVS Module Command Command Name Upon Change to DVS B1h VREF Yes Set to the module's nominal output voltage. B2h IREF Yes 48h OV_FAULT_LIMIT_MULTIPLIER Yes IREF is the output current level in which the module will enter to Constant Current Source. During 52h set to Constant Current, value will be set based on Module Command 4Dh and nominal output current. During 52h set to Latch Type, although the Latch level can be adjusted, the IREF value will be fixed to 120% of the nominal output current. No change from previous value 49h OV_WARN_LIMIT_MULTIPLIER Yes No change from previous value 4Bh UV_FAULT_LIMIT_MULTIPLIER Yes No change from previous value 4Ch UV_WARN_LIMIT_MULTIPLIER Yes No change from previous value 4Dh OC_FAULT_LIMIT_MULTIPLIER Yes No change from previous value 52h OC_RESPONSE_TYPE Yes Set to Constant Current Protection B5h SET_VOLTAGE_RISE_SETTING Yes No change from previous value B6h SET_CURRENT_RISE_SETTING No No change from previous value B7h SET_IO_ACTIVE_LEVEL_LOGIC Yes No change from previous value B8h SET_MODULE__LOAD_TYPE Yes Default to capacitive load type Data "02h" BAh ANALOG_FILTER_ENABLE No No change from previous value *Functional: If Yes, Module Command is operational during the module mode. If No, Module Command is not operational during the module mode To change module output voltage, a B1h (VREF) command to the module. Device Address Module Command Data <Module Slot Address> B1h < Data is the Set Voltage in hexadecimal> *Before writing to the module, please ensure that the Module Command Write Protect (10h) is disabled. *Please refer to Section 5.2 for Module User Configurable Parameters or Appendix B.2 Module Command The user can program the module's output voltage within 5% to 120% of the nominal output voltage rating of the module. For example, a 24V module has a nominal voltage of 24V and can be set to operate between 1.2V and 28.8V. iHP Manual 66 | P a g e iHP Owners Manual Setting the VREF outside the valid range: Setting the VREF value beyond the acceptable range, but not to 0V, the module will trigger a Status CML (Communication Memory Logic) fault and will retain the existing value. Setting the VREF value to 0V, the module will enter to standby mode. To re-enable the module, set VREF to an acceptable range. During a module change of output voltage: 4.4.1.1 OVP is temporary disabled until the output voltage level increases to the commanded VREF. UVP is temporary disabled until the output voltage level decreases to the commanded VREF. IREF will automatically readjust if the voltage request is above the nominal output voltage. This will prevent the module from operating above the rated power. DVS Protection Modes When the supply is in DVS mode, the output is protected against over current, short circuit, over voltage, and under voltage faults. The behavior of the supply during an over current fault or short circuit fault is dependent on whether IREF is set to constant current behavior or latch behavior. In constant current mode, the module will attempt to operate at a constant current level while reducing the output voltage and in latch mode, the supply shut off. In the event of over voltage and under voltage faults, the supply will shut down. Please refer to Section 8 on how to clear the fault and power up the module after fault. 4.4.1.1.1 DVS Protection Over Current Response Over current (OC) response mode will be set by Module Command 52h (OC_RESPONSE_TYPE). The two types of response are Constant Current and Latch. The over current level will be based on Module Command 4Dh OC_FAULT_LIMIT_MULTIPLIER setting. Module command 4Dh OC_FAULT_LIMIT_MULTIPLIER range is 50% to 105% When 52h is set to Constant Current Response, the module will enter constant current mode when load current reaches the IREF value (B2h). The output voltage will decrease to maintain the load current at the current limit. No fault reporting occurs during this condition. The module will revert to normal operation when load current becomes less than IREF value (B2h). The constant current setting, IREF, is dependent on the Vout setting (VREF). When the: Vo (VREF) is below or equal to the nominal voltage IREF = (Inominal) * (OC_FAULT_LIMIT_MULTIPLIER) Vo (VREF) is above the nominal voltage, the IREF, value is automatically reduced to maintain the supply within the maximum peak power of the module IREF = [ (Pnominal) * (OC_FAULT_LIMIT_MULTIPLIER)] / VREF iHP Manual 67 | P a g e iHP Owners Manual Note that the CC setting level, IREF, will be reflected on IREF (Module Command B2h). When 52h is set to Latch Type, the module will shut down when the output current reaches the Latch Level for 500msec and a fault status will be reported. The Latch Current Level setting is dependent on the Vout setting (VREF). When the: Vo (VREF) is below or equal to the nominal voltage Latch Current Level = (Inominal) * (OC_FAULT_LIMIT_MULTIPLIER) Vo (VREF) is above the nominal voltage, Latch Level value is automatically reduced to maintain the supply within the maximum peak power of the module Latch Current Level = [ (Pnominal) * (OC_FAULT_LIMIT_MULTIPLIER)] / VREF Note that latch setting level will NOT be reflected to IREF (Module Command B2h). Latch Level can be determined by computation as stated above. 4.4.1.1.2 DVS Short Circuit Protection When 52h is set to Constant Current Response, the module will shut down when Vo is approximately less than 4% of the nominal for 2 seconds or more. A fault status will be reported. When 52h set to Latch Type Response and an output short circuit occurs, the current level should exceed the latch current level and the module will shut down. A fault status will be reported. 4.4.1.1.3 DVS Protection Over Voltage Protection (OVP) Over voltage protection will be based on Module Command 48h (OV_FAULT_LIMIT_MULTIPLIER) and B1h (VREF), OV Level = (48h OV_FAULT_LIMIT_MULTIPLIER) x (B1h VREF) The module will shut down when the output voltage reaches the OVP level and a Fault status will be reported. 4.4.1.1.4 DVS Protection Under Voltage Protection (UVP) Under voltage protection will be based on Module Command 4Bh (UV_FAULT_LIMIT_MULTIPLIER) and B1h (VREF), UV Level = (4Bh UV_FAULT_LIMIT_MULTIPLIER) x (B1h VREF) The module will shut down when the output voltage is less than UVP level and a fault status will be reported. Note that output UVP will be disabled when the module enters constant current protection. iHP Manual 68 | P a g e iHP Owners Manual 4.4.2 Digital Current Source (DCS) In this operating mode, user has the capability to control the output current using digital means. A PC or laptop will be required to change the output current. To change to Digital Current Source (DCS) mode, the user needs to send below commands to ISOCOMM. Device Address ISOCOMM Command Data1 Data2 00h D3h <Module slot or Group #> 0x08h *Before writing to the ISOCOMM, please ensure that the ISOCOMM Command Write Protect (10h) is disabled. Where: Data1 please refer to ISOCOMM Command Table. Data2 "08h" signifies Digital Current Source. After sending ISOCOMM Command D3h, module will momentarily shutdown, re-initialize and restart. The shutdown, re-initialize, and restart process takes approximately 1.5 seconds. Since the module will reinitialize, the Module Operational Command (01h) and Module Write Protect Command (10h) will be set to enable. IREF will automatically be set to 0A. Table 4-17 list the status of the module command and the functionality of the commands when configuring the module to DCS mode.

Device Address Module Command Data <Module Slot Address> B2h < Data is the Set Current> *Before writing to the module, please ensure that the Module Command Write Protect (10h) is disabled. * Please refer to Section 5.2 for Module User Configurable Parameters or Appendix B.2 Module Command The user can program the module's output current within 0% to 100% of the nominal output current. Setting the IREF value beyond the acceptable range, but not to 0A, the module will trigger a Status CML fault and will retain the existing value. Setting the IREF value to 0A will cause the module to enter to standby mode. To enable again the module, set IREF to an acceptable range. 4.4.2.1 DCS Protection Modes When the supply is in DCS mode, the supply limits the current to the IREF value and the voltage is limited by the VREF value. Secondary output protection is provided in rare load conditions by the OC Fault Level and the OV Fault Level. 4.4.2.1.1 DCS Protection: Constant Voltage Clamp There are conditions that can exist when the output voltage will be greater than the VREF level (B1h) Fixed load resistance and the user increases the IREF setting Fixed IREF setting and load resistance increases. When module output voltage reaches the VREF level, the module will enter constant voltage mode. This will protect the module from continuous increase in output voltage. There will be no fault reporting during this condition. To enter again to DCS, the user needs to decrease the IREF setting or decrease the load resistance. For module software v04.10.00 and above, user can update the Constant Voltage Clamp from nominal voltage down to 5% of the nominal voltage of the module via Module Command B1h. For module software below v04.10.00, constant voltage clamp is fixed to the nominal output voltage. 4.4.2.1.2 DCS Protection: Over Current Response and Short Circuit Protection During DCS, over current response will be fix to "Latch type" (52h). OC level will be based on Module Command 4Dh OC_FAULT_LIMIT_MULTIPLIER setting. Module Command 4Dh OC_FAULT_LIMIT_MULTIPLIER range is 50% to 105% The module will shut down when the output current reaches the OC level and a fault status will be reported. With Vo (VREF) below or equal to the nominal voltage, the latch level setting value is Latch Current Level = (Inominal) * (OC_FAULT_LIMIT_MULTIPLIER) Note that the latch setting level will NOT be reflected to IREF (Module command B2h). Latch level can be determined by computation as stated above. iHP Manual 70 | P a g e iHP Owners Manual 4.4.2.1.3 DCS Protection: Over Voltage Protection (OVP) Over voltage protection level during DCS will be based on the OV Fault Limit Multiplier (48h) and VREF (B1h) setting. OV Level = (48h OV_FAULT_LIMIT_MULTIPLIER) x (B1h VREF) The module will shut down when the output voltage reaches the OVP level and a fault status will be reported. 4.4.2.1.4 DCS Protection: Under Voltage Protection (UVP) During DCS operating mode, under voltage protection is not functional. 4.4.3 Module Grouping for Series or Parallel Connection Digital Operation Modules can be operated in Series or Parallel connection during Digital Mode. Below are list of possible series or parallel connections. DVS parallel connection DVS series connection DCS parallel connection To work properly, the modules must be connected in parallel or series. Only modules of the same model can be connected in series or in parallel. When a certain module will be included in the group, there are restrictions in place to protect the user and system. Please refer to Section 5.1.5.2 for Module Grouping configuration and Section 6 for Module Grouping details. 4.4.3.1 DVS Parallel Connection All modules connected in parallel should: be grouped as one using ISOCOMM WebTool. have the same module configuration. have positive terminals connected in parallel. have negative terminals connected in parallel. have "ISHARE" signals (Module's J2 pin 10) star connected. have "D_RTN" signals (Module's J2 pin 4) star connected. have "REMOTE_SENSE_+" star connected and connected to the desired point of regulation. have "REMOTE_SENSE_-" star connected and connected to the desired point of regulation. To change Group Module output voltage, the user needs to send below B1h (VREF) command to the group. Device Address Module Command Data <Group Number> B1h < Data is the Set Voltage> *Before writing to this command, please ensure that the Group Address Write Protect (10h) is disabled. The group output voltage can be programmed within 5% to 120% of the nominal output voltage. Setting the VREF value beyond the acceptable range, but not to 0V, the module will trigger a Status CML fault and will iHP Manual 71 | P a g e iHP Owners Manual retain the existing value. Setting the VREF value to 0V, the module will enter to standby mode. To enable again the module, set VREF to an acceptable range. During group module change of output voltage: All modules in the group will adjust based on the commanded output voltage. OVP is temporarily disabled until the output voltage level reaches the commanded VREF. UVP is temporarily disabled until the output voltage level reaches the commanded VREF. IREF will automatically readjust if the voltage request is above the nominal output voltage. This will prevent module to operate above the rated power. 4.4.3.1.1 DVS Parallel Connection Protection Each individual module in a group will protect independently. Each individual module in a group will protect as stated on section 4.4.1.1. 4.4.3.2 DVS Series Connection All modules connected in series should: be grouped as one using ISOCOMM WebTool. have the same module configuration. have the terminals connected in series. have each module's "REMOTE_SENSE_+" connected to its own positive output terminal. have each module's "REMOTE_SENSE_-" connected to its own negative output terminal. connect external reverse biased anti-parallel diode to each module output.

Device Address <Group Number> Module Command B1h Data < Data is the Set Voltage> *Before writing to this command, please ensure that the Group Address Write Protect (10h) is disabled. The desired output voltage setting should be set to the desired output voltage at the load. Series Operation DVS "Data" = Total Output Voltage of the Series Module connection. For example, when setting four modules in series to obtain an output voltage of 80V, the group command B1h should be set to 80V. Internally ISOCOMM will divide the set voltage by the number of modules and will set each module to an output voltage of 20V. The module's output voltage can be programmed within 5% to 120% of the nominal output voltage. Setting the VREF beyond the acceptable range, but not to 0V, the module will trigger a Status CML fault and will retain the existing value. Setting the VREF value to 0V, the module will enter standby mode. To enable the module again, set VREF to an acceptable range. During group module change of output voltage: All modules in the group will adjust based on the computed output voltage for each module. OVP is temporary disabled until the output voltage level increases to the commanded VREF. UVP is temporary disabled until the output voltage level decreases to the commanded VREF. iHP Manual 73 | P a g e iHP Owners Manual IREF will automatically readjust if the voltage request is above the nominal output voltage. This will prevent module to operate above the rated power. 4.4.3.2.1 DVS Series Connection Protection Each individual module in a group will protect independently, as stated in Section 4.4.1. 4.4.3.3 DCS Parallel Connection All modules connected in parallel should: be grouped as one using ISOCOMM WebTool have the same module configuration. have output positive terminals connected in parallel. have output negative terminals connected in parallel. The module will clamp into constant voltage source if the requested IREF or load resistance increases enough to cause the output voltage to be greater than the VREF. To operate the group in this condition: All Module REMOTE_SENSE_+ should be star connected and connected to the desired point of regulation. All Module REMOTE_SENSE_- should be star connected and connected to the desired point of regulation. All Module ISHARE signal (Module's J2 pin 10) should be star connected. All Module D_RTN signal (Module's J2 pin 4) should be start connected. To change module output current, send below B2h (IREF) command using Group Device Address. Device Address Module Command Data <Module Slot Address> B2h < Data is the Set Current> *Before writing to this command, please ensure that the Group Address Write Protect (10h) is disabled. The desired output current setting should be set to the desired output current at the load. Parallel Operation DCS "Data" = Total Output Current of the Parallel Module connection. For example, when setting four modules in parallel to obtain an output current of 100A, the group command B1h should be set to 100A. Internally ISOCOMM will divide the set current by the number of module and will set each module output current to 25A. The module's output current can be programmed within 0% to 100% of the nominal output current. Setting the IREF outside the valid range will cause the modules to trigger an INVALID PGM RANGE fault (STAUS_MFR_SPECIFIC) and turn the output of the modules off. Set the command within valid range to recover. 4.4.3.3.1 DCS Parallel Connection Protection Each individual module in a group will protect independently and will protect as stated in Section 4.4.2. iHP Manual 74 | P a g e iHP Owners Manual 4.5 Analog Control The module's output (output voltage or current) can be controlled using an external supply connected to the modules' IPROG (0-10VEXT_IPROG or 0-5VEXT_IPROG) or VPROG (0-10VEXT_VPROG or 0-5VEXT_VPROG) signal. Definition of module is in Appendix B.2 Module Command. Definition of ISOCOMM Command is in Appendix B.3 ISOCOMM Command. 4.5.1 Analog Voltage Source (AVS) In this operating mode, the user has the capability to control the output voltage using analog means. For AVS, user can control the output using the 0-5VEXT_VPROG or 0-10VEXT_VPROG input. To change to Analog Voltage Source (AVS) mode, the user needs to send the below commands to ISOCOMM. Device Address Command Data1 Data2 00h D3h <Module slot or Group #> 02h *Before writing to the ISOCOMM, please ensure that the ISOCOMM Command Write Protect (01h) is disabled. Where: Data1 please refer to ISOCOMM Command Table. Data2 "0x02h" signifies Analog Programmed Voltage Source. After sending ISOCOMM Command D3h, the module will momentarily shutdown, re-initialize and restart. This will happen for 1.5 seconds. Since the module will re-initialize, the Module Operational Command (01h) and Module Write Protect Command (10h) will be set to enable. The module output voltage will be based on the VPROG signal. Table 4-19 lists the status of the module command and the functionality of the commands when configuring the module to DCS mode. iHP Manual 75 | P a g e iHP Owners Manual Table 4-19 Module Command Command Name Functional in AVS B1h B2h VREF IREF No Yes Upon Change to AVS Fix to Module's Nominal Output Voltage During 52h set to Constant Current, value will be set based on Module Command 4Dh and nominal output current. 48h OV_FAULT_LIMIT_MULTIPLIER No During 52h set to Latch Type, value will be fixed to 120% of the nominal output current.

If No, command register is not operational during the module mode To change the output voltage using 0-10VEXT_VPROG, apply 0-10V across the connector J1's pin 1 (010VEXT_VPROG) and pin 8 (SYS_RTN) to get a corresponding output voltage from 5% to 120% of the nominal output voltage. Applied voltage 0V - 0.42V yields 5% nominal output voltage. To change the output voltage using 0-5VEXT_VPROG, apply 0-5V across the connector J1's pin 2 (05VEXT_VPROG) and pin 8 (SYS_RTN) to get a corresponding output voltage from 5% to 120% of the nominal output voltage. Applied voltage 0V - 0.21V yields 5% nominal output voltage. Note: IREF will automatically readjust if the voltage request is above the nominal output voltage. Please note that 0-10VEXT_IPROG and 0-5VEXT_IPROG cannot be used simultaneously: If the user will use 0-10VEXT_VPROG, 0-5VEXT_VPROG should be floating. If the user will use 0-5VEXT_VPROG, 0-10VEXT_VPROG should be floating. iHP Manual 76 | P a g e iHP Owners Manual 4.5.1.1 AVS Protection Modes When the supply is in AVS mode, the output is protected against over current, short circuit, over voltage, and under voltage faults. The behavior of the supply during an over current fault or short circuit fault is dependent on whether IREF is set to constant current behavior or latch behavior. In constant current mode, the module will attempt to operate at a constant current level while reducing the output voltage and in latch mode the supply shut off. In the event of an overvoltage and under voltage faults the supply will shut down. Please refer to Section 8 on how to clear the fault and power up the module after fault. 4.5.1.1.1 AVS Protection Over Current Response Over current response mode will be set by Module Command 52h (OC_RESPONSE_TYPE). The two types of response are Constant Current and Latch. The over current level will be based on Module Command 4Dh OC_FAULT_LIMIT_MULTIPLIER setting. Module Command 4Dh OC_FAULT_LIMIT_MULTIPLIER range is 50% to 105% When 52h set to Constant Current Response, the module will enter constant current mode when load current reaches the IREF value (B2h). The output voltage will decrease to maintain the load current at the current limit. No fault reporting occurs during this condition. The module will revert to normal operation when load current becomes less than IREF value (B2h). The constant current setting, IREF, is dependent on the Vout setting (VREF). When the: Vo (VREF) is below or equal to the nominal voltage IREF = (Inominal) * (OC_FAULT_LIMIT_MULTIPLIER) Vo (VREF) is above the nominal voltage, the IREF, value is automatically reduced to maintain the supply within the maximum peak power of the module IREF = [ (Pnominal) * (OC_FAULT_LIMIT_MULTIPLIER)] / VREF Note that the CC setting level, IREF, will be reflected on IREF (Module Command B2h). When 52h set to Latch Type, the module will shut down when the output current reaches the latch level for 500msec and a fault status will be reported. The Latch Current Level setting is dependent on the Vout setting (VREF). When the: Vo (VREF) is below or equal to the nominal voltage Latch Current Level = (Inominal) * (OC_FAULT_LIMIT_MULTIPLIER) iHP Manual 77 | P a g e iHP Owners Manual Vo (VREF) is above the nominal voltage, Latch Level value is automatically reduced to maintain the supply within the maximum peak power of the module Latch Current Level = [ (Pnominal) * (OC_FAULT_LIMIT_MULTIPLIER)] / VREF Note that the latch setting level will NOT be reflected to IREF (Module Command B2h). Latch level can be determined by computation as stated above. 4.5.1.1.2 AVS Short Circuit Protection When 52h is set to Constant Current Response, the module will shut down when Vo is approximately less than 4% of the nominal for 2 seconds or more. A fault status will be reported. When 52h set to Latch Type and an output short circuit occurs, the current level should exceed the latch current level and the module will shut down. A fault status will be reported. 4.5.1.1.3 AVS Protection Over Voltage Protection (OVP) Tracking over voltage protection Module Command 48h (OV_FAULT_LIMIT_MULTIPLIER) is not operational during AVS. A Brick Wall OVP is operational during this mode. In Brick Wall OVP mode the limit is hard coded in module firmware at the factory and cannot be changed. The module will shut down when the output voltage reaches the Brick Wall OVP level. Brick Wall OVP level is specified in Section 4.1.2 and a fault status will be reported. 4.5.1.1.4 AVS Protection Under Voltage Protection (UVP) During ACS operating mode, under voltage protection is not functional. 4.5.2 Analog Current Source (ACS) In this operating mode, the user has the capability to control the output current using analog means. For ACS, the user can control the output using 0-5VEXT_IPROG or 0-10VEXT_IPROG To change to Analog Current Source (ACS) mode, the user needs to send below commands to ISOCOMM. Device Address Command Data1 Data2 00h 0xD3h <Module slot or Group #> 0x0Ah *Before writing to the ISOCOMM, please ensure that the ISOCOMM Command Write Protect (01h) is disabled. Where: Data1 please refer to ISOCOMM Command Table. Data2 "0x0Ah" signifies Analog Programmed Voltage Source. After sending ISOCOMM Command D3h, the module will momentarily shutdown, re-initialize and restart. The shutdown, re-initialize and restart process takes approximately 1.5 seconds. Since the module will re-initialize, the Module Operational Command (01h) and Module Write Protect Command (10h) will be set to enable. The module output current will be based on the IPROG signal. iHP Manual 78 | P a g e iHP Owners Manual Table 4-20 lists the status of the module command and the functionality of the commands when configuring the module to ACS mode. Table 4-20 Module Command Command Name Functiona l in ACS B1h B2h 48h VREF IREF OV_FAULT_LIMIT_MULTIPLIER Yes No Yes Upon Change to ACS Fix to nominal Fix to 0A OVP will be based on the set VREF. OVP multiplier no change from previous value. 49h OV_WARN_LIMIT_MULTIPLIER Yes OV Warning will be based on the set VREF. OVP warning multiplier no change from previous value. 4Bh UV_FAULT_LIMIT_MULTIPLIER No No change from previous value 4Ch UV_WARN_LIMIT_MULTIPLIER No No change from previous value 4Dh OC_FAULT_LIMIT_MULTIPLIER Yes No change from previous value 52h OC_RESPONSE_TYPE Yes Fix to Latch type B5h SET_VOLTAGE_RISE_SETTING No No change from previous value B6h SET_CURRENT_RISE_SETTING No No change from previous value B7h SET_IO_ACTIVE_LEVEL_LOGIC Yes No change from previous value B8h SET_MODULE__LOAD_TYPE Yes Last user B8h command. Artesyn Factory setting of DCS is Resistive (01h). Bah ANALOG_FILTER_ENABLE No No change from previous value *Functional: If Yes, command register is operational during the module mode. If No, command register is not operational during the module mode To change the output current using 0-10VEXT_IPROG, apply 0-10V across connector J1's pin 3 (010VEXT_IPROG) and pin 8 (SYS_RTN) to get a corresponding output current from 0% to 100% of the rated output current. To change the output current using 0-5VEXT_IPROG, apply 0-5V across connector J1's pin 4 (0-5VEXT_IPROG) and pin 8 (SYS_RTN) to get a corresponding output current from 0% to 100% of the rated output current. Please note that 0-10VEXT_IPROG and 0-5VEXT_IPROG cannot be used simultaneously: If the user will use 0-10VEXT_VPROG, 0-5VEXT_VPROG should be floating. If the user will use 0-5VEXT_VPROG, 0-10VEXT_VPROG should be floating. iHP Manual 79 | P a g e iHP Owners Manual 4.5.2.1 ACS Protection Modes When the supply is in ACS mode, the supply limits the current to the IREF value and the voltage is limited by the VREF value. Secondary output protection is provided in rare load conditions by the OC fault level and the OV fault level. Please refer to Section 8 on how to clear the fault and power up the module after fault. 4.5.2.1.1 ACS Protection: Constant Voltage Clamp There are conditions that can exist when the output voltage will be greater than the VREF level (B1h): Fix load resistance and user increases the IPROG input. Fix IPROG input setting and load resistance increases. When module output voltage reaches the VREF level, the module will enter constant voltage clamp. This will protect the system from continuous increase in output voltage. There will be no fault reporting during this condition. To enter again to ACS, the user needs to decrease the IPROG input or decrease the load resistance. For module software v04.10.00 and above, the user can update the Constant Voltage Clamp from nominal voltage down to 5% of the nominal voltage of the module via Module Command B1h. For module software below v04.10.00, Constant Voltage Clamp cannot be changed and is set to the nominal output voltage. 4.5.2.1.2 ACS Protection: Over Current Protection and Short Circuit Protection During ACS, over current protection will be fix to "latch type" (52h). OC level will be based on Module Command 4Dh OC_FAULT_LIMIT_MULTIPLIER setting. Module Command 4Dh OC_FAULT_LIMIT_MULTIPLIER range is 50% to 105% The module will shut down when the output current reaches the OC level and a fault status will be reported. With Vo (VREF) below or equal to the nominal voltage, the latch level setting value is Latch Level = (Inominal) * (OC_FAULT_LIMIT_MULTIPLIER) Note that the latch setting level will NOT be reflected to IREF (Module Command B2h). Latch Level can be determined by computation as stated above. 4.5.2.1.3 ACS Protection: Over Voltage Protection (OVP) Over voltage protection level during ACS will be based on the OV Fault Limit Multiplier (48h) and VREF (B1h) setting. OV Level = (48h OV_FAULT_LIMIT_MULTIPLIER) x (B1h VREF) 4.5.2.1.4 ACS Protection: Under Voltage Protection (UVP) During ACS operating mode, under voltage protection is not functional 4.5.3 Module Grouping for Series or Parallel Connection Analog Operation Modules can be operated in Series or Parallel connection during analog mode. Below are list of possible series or parallel connections: iHP Manual 80 | P a g e iHP Owners Manual AVS parallel connection AVS series connection ACS parallel connection To work properly, user needs to group the modules connected in parallel or series.

Please refer to Section 4.3 for the function of VREF with respect to module mode. iHP Manual 106 | P a g e iHP Owners Manual Module Group Module Group function was designed to treat multiple modules in a rack as one. The main function of module grouping is to provide a: 1. Single command for all modules in a group (limited command). 2. Single status reporting for all modules in a group. 3. Single reporting of Vo, Io, and Po for all modules in a group. Modules are REQUIRED to be grouped as one during parallel or series connections. Using a group address, the modules included in the group will receive the write command simultaneously. Individual write command to a module is not allowed when a module belongs to a group. This is needed during parallel or series operation in which the module should react simultaneously. Ex. Changing VREF to change the output voltage. Changing IREF to change the output current. User will need to configure in the ISOCOMM WebTool. Please refer to Section 5.1.5. Modules will be allowed to be included in one group only. 6.1 Group Device Address ISOCOMM SWv02.08.00 and below have four module groupings. ISOCOMM SW v03.00.00 and onwards have seven module groupings. Instead of using ISOCOMM or module device address to send WRITE or READ command, Group device addresses are available. There are seven groupings available. Each group has a specific, unique device address. iHP Manual Group Device Address Group Number 18h Group 1 19h Group 2 1Ah Group 3 1Bh Group 4 1Ch Group 5 1Dh Group 6 1Eh Group 7 107 | P a g e iHP Owners Manual The group address will be used to send READ or WRITE commands to all modules included in the group. Only one READ or WRITE command sent is needed to simultaneous command all modules in a group. 6.2 Group Initialization at Start up Group initialization will take place after ISOCOMM boot sequence. If the grouping function is activated, ISOCOMM will check the configuration of each module. Each specific configuration should be the same in each module that belongs to a group. If there are discrepancies in the module configurations, all iHP modules in the iHP rack will not be allowed to turn-on. ISOCOMM command 80h (MFR Status) low byte bit 4 will be asserted (Group Mismatch Fault). ISOCOMM will check if below configuration are the same for each module that belongs to a group.

When the modules are inserted in different iHP rack and there is a need to synchronize turn-on or turn-off of the modules. During multi-rack operation, Rack Synchronization Off should be enabled. This function can be configured in the ISOCOMM WebTool Rack section. The number of racks included in the multi-rack operation should be selected. Rack Synchronization OFF is REQUIRED when modules in parallel or series are connected to different iHP racks. The main purpose of Rack Synchronization Off is to ensure that all modules in the multi-rack operation: Turn-on simultaneously Turn-off when there is at least one module at fault. Turn-off when there is at least one module commanded to turn-off via hardware or software. When Rack Synchronization Off Operation is enabled, Module Synchronization Off will be automatically enabled, but requires each rack be connected via Ethernet communication as it uses Ethernet communication to perform this function. All IP addresses of the iHP rack, router and PC should be the same except for the last octet. For example, each IP address will start at 192.168.2.xxx and each iHP rack, router and PC will have a unique value for xxx (except for 0 and 255) The following diagram shows the system configuration for Rack Synchronization OFF Ethernet communication. iHP Manual 112 | P a g e iHP Owners Manual Each rack will send status via the communication lines. Rack status during multi-rack operation can be either: GOOD FAULT/STANDBY To have an iHP rack status "GOOD", all of these conditions are met: All modules included in the rack do not have any Latching Fault or Auto-recoverable Fault iHP rack does not have any Latching Fault or Auto-recoverable Fault All modules included in the rack are NOT in standby mode via Using software Operational command. Using module hardware signal (Module Enable or Module Inhibit signal). Using iHP rack hardware signal (Global Enable/Inhibit signal). If any below scenario occurred, the status "FAULT/STANDBY" will be reported by the iHP rack. At least one module included in the rack has a Latching Fault or Auto-recoverable Fault iHP rack has any Latching Fault or Auto-recoverable Fault At least one module included in the rack is in standby mode via Using software Operational command. Using module hardware signal (Module Enable or Module Inhibit signal). Using iHP rack hardware signal (Global Enable/Inhibit signal). Using Power SW button located in the front panel. 7.1 During Turn-On iHP rack with Rack Synchronization OFF enabled will communicate to each other via Ethernet. Each iHP rack will get all the IP addresses (for Ethernet) of all rack with enabled Rack Synchronization OFF. This will be recorded in the ISOCOMM WebTool. Aside from the communication address, the rack serial number will also be recorded and shown in the ISOCOMM WebTool. Ex. iHP rack with IP address: 192.168.2.100 Rack Synchronization OFF is ENABLED Number of racks connected is three. 192.168.2.100 is included in the three iHP rack. The remaining two will be reflected on 192.168.2.100 WebTool Home page. iHP Manual 113 | P a g e iHP Owners Manual Each rack with enable Rack Synchronization Off will send its status via Ethernet communication. When the status of all racks are "GOOD", all module outputs will turn-on. 7.2 During Turn-off o iHP rack with fault or standby will send a "FAULT/STANDBY" status via Ethernet. Once the iHP rack receives the "FAULT/STANDBY" status, each iHP rack will shut down all modules. After this, the iHP rack with Fault or Standby status will continue to broadcast the "FAULT/STANDBY" from time to time until the fault is clear or standby mode is deactivated. 7.3 From Module Standby Activated to Module Standby De-activated. When the module standby is de-activated, the iHP rack will send a status "GOOD" via Ethernet. When all iHP racks in the multi-rack system have a status "GOOD", all modules will turn-on. 7.4 From Fault to Fault Clear. When the module recovers from fault condition latch condition, the iHP rack will send a status "GOOD" via Ethernet. When all iHP racks in the multi-rack system have a status "GOOD", all modules will turn-on. 7.5 Broadcast Command on Multi Rack Operation Broadcast command is recommended when modules in each iHP Rack in Multi Rack operation are grouped; see Section 6 on how to group modules. Group address on each Rack should be the same in order to do broadcast command. iHP Manual 114 | P a g e iHP Owners Manual Above sample Multi Rack operation is using 2 units of iHP 12KW Rack with two modules each inserted per Rack. The 2 modules, Module 1 & Module 2 are group in Group 1. Broadcast address is set at 192.168.2.255. Using Group 1 address, the modules included in the group will receive the write or read command simultaneously. iHP Manual 115 | P a g e iHP Owners Manual Faults and Output Recovery. 8.1 Module Fault Fault Output Voltage Over Voltage Fault.
