Notification of the Refer to Chart 1. status is provided using the alarm display and the tripping alarm output (TRP). (See notes 2, 3 and 4.) The alarm display will alternate between the voltage and the alarm code (A10). The primary voltage is measured at the input terminals. Detection voltage: 28.8 V (fixed) Abnormal current tripping The output current is monitored and the branch output that is abnormal is cut off if the preset current is reached. Refer to Chart 2. Notification of the status is provided using the alarm display and the tripping alarm output (TRP). (See notes 2 and 3.) The alarm display will alternate between the current and the alarm code (A11). Abnormal current detection setting range: 0.5 to 4.0 A (S8M-CP04-RS: 0.5 to 0.38 A) in 0.1-A units. Either of two abnormal current tripping types can be set. Standard detection: Tripping within 100 ms. (If a current exceeding the set value flows for 80 ms or more, it is detected as an abnormal current and power is cut off within 20 ms.) Instantaneous detection: Tripping within 20 ms. (If a current exceeding the set value flows for 10 ms or more, it is detected as an abnormal current and power is cut off within 10 ms.) (Refer to page 14 for the setting procedure.) Tripping by external signal The output can be cut off by inputting a voltage to the external tripping input (TRG terminal). If a shutdown sequence (See note 2.) has been set, outputs will be cut off according to the shutdown sequence. (Refer to page 14 for information on the shutdown sequence.) External input signal width: 10 ms min. External tripping enable/disable setting: Enabled Input signal levels High level: 19.2 to 30 VDC Low level: 0 to 2.5 VDC Tripping can also be performed by using communications (S8M-CP04-R/RS only). Refer to the S8M User's Manual (Cat. No. Z241) for information on tripping using communications. Note: 1. Two abnormal current tripping types are supported depending on the tripping current characteristics: Standard detection and instantaneous detection. Select the required tripping type. 2. Outputs are cut off using semiconductor relays and electrical insulation is not provided. 3. The output will remain OFF and the alarm display and alarm output will not be cleared even if power is restored. The S8M must be reset to restore operation. (Refer to List of Alarms on page 16 for details.) 4. The voltage at the power input terminals is monitored to detect abnormal voltages. To confirm correct output voltages, measure the voltages at the branch output terminals.

The connection timing for branch outputs 1 to 4 can be set individually to offset the connection timing of load devices. Creating time delays between starting loads enables safe load operation. It also reduces total inrush current so that power supply capacity can be optimized. Setting range: 0.0 to 99.0 s in 0.1-s units. (See note.) (Refer to page 14 for the setting procedure.) Shutdown sequence (Refer to Chart 6.) The cutoff timing for branch outputs 1 to 4 can be set individually to offset the cutoff timing of load devices for the external tipping input or to enable an emergency stop. Setting range: 0.0 to 99.0 s in 0.1-s units. (See note.) (Refer to page 14 for the setting procedure.) Startup delay A delay function is provided so that the abnormal current tripping function or overcurrent alarm function will not be triggered by large initial surge currents, e.g., for capacitive loads or lamp loads. The abnormal current tripping function will function once the set time has elapsed. (Note: The delay is fixed at 70 ms.) Current Alarm function disabled for large surge currents at startup. 0 t 70 ms: Delay Note: The sequencing functions are designed for the four branch outputs of one S8M. There is no sync processing between S8M Protectors when more than one S8M is used.

The following modes can be selected from the Mode Selection Menu using the Up and Down Keys. Run Mode Used for normal operation. (1) Run Mode Setting Mode Used to set or change S8M parameters. Test Mode In Run Mode, the current, input voltage, and other values are displayed for the branch outputs. Use this mode for operation once initial settings and system adjustments have been completed. Used to test operation for devices connected to the S8M. Note: Refer to the S8M User's Manual (Cat. No. Z241), when having further setting. Initial Settings When First Using the S8M The following diagram illustrates mode transitions for the S8M. When the S8M is turned ON for the first time, it will enter Setting Mode. First set the required initial settings for the parameters in Setting Mode and then switch to Test Mode or Run Mode. (2) Setting Mode Setting Mode is used to set parameters. Operation starts from this mode when using the S8M for the first time. (3) Test Mode Test Mode enables forcing branch outputs ON and OFF. Connections and cutoffs can be manipulated for all outputs for each branch output. By default, all outputs will be OFF. Test Mode is thus used to turn ON branch outputs as required. (4) Protection Level Protection Level can be used to set restrictions for reading and writing parameters. Three levels, levels 0, 1, and 2, are available. The default is level 1. Refer to the S8M User's Manual (Cat. No. Z241) for the parameters that are protected in each level. Power ON When power was turned OFF in any mode except Test Mode When power was turned OFF in Test Mode Mode Selection Menu Run Mode (5) Parameter Initialization Parameter Initialization is used to return all parameters to their default settings. The Parameter Initialization is not displayed in the default protection level (level 1), and the protection level must be set to level 0 to initialize parameters. Refer to the S8M User's Manual (Cat. No. Z241) if initialization is required. Run Mode run (RUN) Press for 3 s. Setting Mode set (SET) Setting Mode Test Mode tst (TST) Test Mode Press for 3 s. Protection Level prt (PRT) Press for 3 s.

Recommended Wire Types !CAUTION Terminals Minor electric shock, fire, or Product failure may occasionally occur. Do not disassemble, modify, or repair the Product or touch interior of the Product. Wiring materials Torque Solid, 1.08 N*m Power input AWG14 terminals (2.081 mm2) x 2 Stranded (9.6 in. lb.) Strip length 8 to 10 mm Minor burns may occasionally occur. Do not touch the Product while power is being supplied or immediately after power is turned OFF. Branch output terminals AWG16 to 20 (1.309 to 0.517 mm2) 0.8 to 1.0 N*m 6 to 7 mm (7.2 to 8.8 in. lb.) Fire may occasionally occur. Tighten terminal screws to the specified torque. Power input terminals: M4 1.08 N*m (9.6 in. lb.) Branch output terminals: M3.5 0.8 to 1.0 N*m (7.2 to 8.8 in. lb.) Other terminals AWG18 to 26 (0.823 to 0.129 mm2) --- Do not apply more than 100-N force to the terminal block when tightening screws. Minor electric shock, fire, or Product failure may occasionally occur. Do not allow any pieces of metal or conductors or any clippings or cuttings resulting from installation work to enter the Product. Be sure to remove the sheet covering the S8M for machining before power-ON so that it does not interfere with heat dissipation. Installation Environment The Product will be damaged. Do not incorrectly connect the polarity of power input terminals. Do not use the S8M in locations subject to shocks or vibrations. In particular, install the S8M as far away as possible from contactors or other devices that are vibration sources. Additionally, install a PFP-M End Plate on each end of the S8M. Precautions for Safe Use Install the S8M well away from any sources of strong, high frequency noise and surge. Mounting Take adequate measures to ensure proper heat dissipation to increase the long-term reliability of the S8M. Install the S8M so that the air flow circulates around it, because the S8M is designed to radiate heat by means of natural air flow. Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. Do not use any mounting method other than a standard one. Side-by-side mounting of two or more S8M is possible. The switch mode power supply connected to inputs and any other sources of heat, however, must be separated as shown below. (See note 1.) 10 mm (See note 2.) Operating Life The life of the S8M is determined by the life of the electrolytic capacitors used inside. Here, Arrhenius Law applies, i.e., the life will be halved for each rise of 10C or the life will be doubled for each drop of 10C. The life of the S8M can thus be increased by reducing its internal temperature. Ambient Operating and Storage Environment Store the S8M at a temperature of -25 to 65C and a humidity of 25% to 90%. Internal parts may occasionally be deteriorated or damaged. Do not use the S8M in areas outside the derating curve (i.e., in the area shown by shading ( ) in the derating curve diagram on page 6). Surrounding air temperature for UL 508 Listing and UL60950-1 Recognition is 50C. (See note 1.) (See note 3.) (See note 4.) Note: 1. Convection of air 2. 75 mm min. 3. 75 mm min. 4. 10 mm min. Use the S8M at a humidity of 25% to 85%. Do not use the S8M in locations subject to direct sunlight. Do not use the S8M in locations where liquid, foreign matter, or corrosive gases may enter the S8M. Input Voltage Input voltage range: 19.2 to 26.4 VDC Wiring Minor electric shock during operation may occasionally occur. Always attach the terminal cover when using the S8M. The S8M provides abnormal voltage protection. All branch outputs will be cut off if the input voltage exceeds 28.8 VDC. This function, however, does not protect loads and internal parts from high voltages in all cases. Be sure the input voltage is within the rated range. Minor fire may possibly occur. Ensure that input and output terminals are wired correctly. Outputs may be cut off by the abnormal voltage protection with loads that generate reverse peak electromotive force. Increases in the temperature of internal parts resulting from heating of wiring materials may result in deterioration or damage to internal parts. Use wiring materials suitable to the current being used. The following wiring materials, torque and strip length are recommended to prevent heating and possible fires in wiring materials. The S8M operates by DC input. Do not connect AC input to power input terminals. 20 S8M Input Power Supply Selection Startup Delay The overcurrent protection characteristics of the power supply connected to the input side can cause a voltage drop, resulting in tripping. The startup delay will not operate when a relay or other device is used for ON/OFF control on the output side of the S8M, so a tripping operation may occasionally occur. If the capacity of the input power supply is too small compared with the load, the overcurrent protection characteristics of the power supply can cause the failure of S8M operating or tripping by voltage drop occasionally. Select a Power Supply Unit with a current capacity that is 10 to 12 A higher than the maximum current supply to the connected devices. Connections It is possible to connect S8M like below. Correct If the input power supply starts or stops too slowly, the overcurrent protection characteristics of the power supply can cause the failure of S8M operating or tripping by voltage drop occasionally. +V Power supply +V +V -V -V -V +V S8M -V +V -V +V -V Tripping Performance +V Always remove the cause of the output first and then reset the alarm when abnormal tripping operates. -V +V -V +V S8M -V When using a load with a fixed power operation, the S8M may cause tripping when the power is turned OFF. Internal parts may possibly be deteriorated or damaged. Do not repeatedly perform tripping or recovery operations more than necessary. Tripping performance depends on the ambient operating temperature. Use the S8M within the derating curve shown in the derating curve diagram on page 6. Dielectric Strength Test The S8M is designed to withstand 500 VAC for 1 minute between I/O terminals, all branch output terminals, all output signal terminals, the external tripping input terminals, and all communications terminals of the S8M. -V +V +V -V Series connections, such as connecting an S8M to the output of another S8M, are not possible. Incorrect +V Power supply +V +V -V -V -V V +V S8M S8M -V +V V -V +V -V The S8M may possibly be damaged from the impulse voltage if a testing device switch is used to abruptly apply or shut off 500 VAC. Increase the applied voltage gradually using the voltage adjustment on the testing device. Always short the specified terminals so that the voltage is applied to all of the terminals at the same time. Power input terminals and branch output terminals are not isolated. Do not perform dielectric strength tests or other insulation appraisal testing between inputs and outputs. External Tripping Input When using the external tripping input, always confirm the application methods described in the S8M User's Manual (Cat. No. Z241) before designing the system. Display The voltage detection function monitors the voltage at the power input terminals. Measure the voltage at the branch output terminals to confirm that the output voltage is correct. Backup Device Connections Observe the following precautions when using a backup device, such as one from OMRON's S8T Series. * When connecting a backup device to an S8M branch output, the backup current will be supplied to other branches through internal circuits and it is conceivable that internal parts may be deteriorated or damaged at the same time. When using a backup device with the S8M, connect the backup device to the power input side. * When connecting a backup device to the S8M input side, the backup time will be shorter than normal due to internal power consumption. Always confirm the backup time when using a backup device. 21 S8M Troubleshooting If the S8M is not operating properly, check the items listed in the following table before requesting repairs.
