The indicator has several built-in diagnostic functions to alert operators of any malfunction. Extensive testing of noise interference mechanisms and full burn-in makes the indicator extremely reliable in industrial environments. The die-cast front bezel meets NEMA 4/IP65 requirements for washdown applications. Plug-in style terminal blocks simplify installation wiring and change-outs. The Apollo Intelligent Strain Gage Meter (IMS) accepts low level signals from a variety of bridge-type transducers, such as load cells, pressure transducers, torque transducers, etc. User selectable low (20 mV) and high (200 mV) input ranges and a stable, bridge excitation voltage, that is user selectable 5 V or 10 V at 60 mA, is provided. A two Hz, two pole, low pass filter coupled with programmable digital filtering can be tuned to match the characteristics of most processes. A digital tare (re-zero) operation can be performed at a touch of a button along with recall of process peak and valley (max/min) values. Stateof-the-art digital circuitry virtually eliminates errors due to drift. A full complement of option packages are available to fulfill many process applications. The indicator features a choice of two different scaling procedures which greatly simplifies initial set-up. A full 6-digit display accommodates virtually any process-engineering unit. English Style display prompts aid the operator through set-up and operation. A front panel lock-out menu protects set-up data and operation modes from unauthorized personnel. Programmable remote input E1-CON and/or E2-CON, can be utilized to control a variety of totalizing, alarm control, display hold and tare operations. All set-up data is stored in E2PROM, which will hold data for a minimum of 10 years without power. As a standard feature, all units include an integrator (totalizer)/ linearizer which can be used to totalize or integrate signals up to a maximum display value of 999,999. It features independent scaling and a low signal cut-out to suit a variety of signal integration applications. Additionally, nine slopes and offsets can easily be programmed to linearize transducers with non-linear outputs, such as square law devices. All readings are retained at power-down. Optional dual relays with parallel solid state outputs are fully programmable to operate in a wide variety of modes to suit many control or alarm applications. Optional 20 mA loop, bidirectional serial communications provides computer and printer interfacing to extend the capabilities of the indicator. More than one unit can be connected in the loop with other RLC products which have serial communications capabilities. An optional 4 to 20 mA or 0 to 10 VDC re-transmitted analog output can be scaled by the user to interface with a host of recorders, indicators and DIMENSIONS "In inches (mm)" l SAFETY SUMMARY All safety related regulations, local codes and instructions that appear in the manual or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it.

ENV 50140 - Radio-frequency radiated electromagnetic field 1 ENV 50141 - Radio-frequency conducted electromagnetic field 1 TOTALIZER/LINEARIZER/PEAK/VALLEY/TARE The integrator feature simply totals (adds) input readings with a programmable time base and scaling coefficient. The integrator/totalizer may be reset via a remote input, by the front panel or through the serial communications loop. Alarms may be programmed to trigger from totalizer values, for example to signal total weight thresholds for batching operations. A programmable low signal level disable feature completes the integrator/totalizer features. At loss of power to the indicator, the contents of the totalizer are saved. The linearizer feature is a series of programmable scaling points that are used to construct linear segments to linearize the input signal. The most common application would be to interface with square law devices. A maximum of nine segments are available and using nine segments for a square law device would reduce linearity errors to less than 0.5%. The other features are peak and valley detection and a re-zero (tare) function. The indicator will record the lowest reading (valley) and the highest reading (peak) automatically, for later recall. This information is valuable when monitoring the limits of the process over any length of time (shifts, days, etc.) since these values are stored at power-down. An external input can be programmed to reset or engage the unit into a peak or valley reading indicator. Additionally, the peak and valley can be viewed and reset from the front panel, if so programmed, and viewed and reset through the serial communication option. The re-zero (tare) function can also be controlled externally or by the front panel. This feature can quickly compensate for small shifts or drifts in the input signal or can be used to re-zero after every operation, such as batching. ISOLATED ALARM OPTION The alarm option consists of an additional printed circuit board with 9 connections. Six of these terminals are for the two Form-C relays and the other three are for the two open collector transistors, which act in parallel with the relays. The two alarms are completely independent with programmable values, hysteresis (deadband), high or low acting, auto or manual reset, triggering from input or total, and they can be programmed to track each other, if desirable. If the alarms are programmed to latch (manual reset), then they can be reset either by the front panel or a remote input. The alarms can be set to trigger from either the integrator/totalizer or the input display, such as actuating external alarms, control valves, etc. Alarm #1 can be programmed to track Alarm #2 by enabling alarm tracking. This is useful in alarm set-ups where a pre-warning control activates before a second alarm shuts off the process when tracking is programmed. Changing the shut-off trip value (alarm #2) automatically changes the pre-warn value (alarm #1) an equal amount. Alarm and hysteresis values can be modified through the optional serial communications to provide automatic control. ISOLATED SERIAL COMMUNICATIONS OPTION The serial communication option is a half-duplex, two-way 20 mA loop that can connect to a variety of printers, computers, terminals and controllers to suit many data-polling or automatic operation applications. The indicator responds to a host of commands, including change alarm value, reset totalizer and transmit input signal. Two loops are required for all hook-ups; a transmit (outgoing data) loop and a receive (in-coming data) loop. Since the indicator monitors the receive loop for a busy signal (current interrupted) while transmitting, the receive loop must be connected even if the indicator is transmitting only, such as to a printer. A built-in 20 mA source is provided in the transmit loop. Additionally, multiple units and other Red Lion Controls instruments can be serially addressed, with a maximum address capability of 99 units. (Note: There are hardware limitations which restrict this to a lower number of units per serial loop.) 2 ISOLATED RE-TRANSMITTED ANALOG OUTPUT OPTION 4 to 20 mA 0 to 10 VDC The re-transmitted analog output option transmits a digitally programmable 4 to 20 mA current to drive chart recorders, remote indicators and controllers. The compliance is 10 VDC. Non-standard current ranges within the 4 to 20 mA range can be supported by calculating the slope and intercept of the display/output and calculating the required display values at 4 and 20 mA. The re-transmitted analog output option transmits a digitally programmable 0 to 10 VDC output signal to drive chart recorders, remote indicators and controllers. Non-standard current ranges within the 0 to 10 VDC range can be supported by calculating the slope and intercept of the display/output and calculating the required display values to 0 VDC and 10 VDC. PROGRAMMABLE FUNCTIONS "E1-CON" 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 "E2-CON" Programming of the IMS is divided into modular steps. Each module is a short sequence of data entries. The front panel buttons "UP" and "DOWN" (shown as arrows on the front panel) are used to change the data and set-ups, while the "P" button is used to `save' or `enter' the data. After pressing "P" which gains entry into the programming mode, the programming modules are identified by the message "Pro" and a number in the display. "UP" and "DOWN" are used to select the desired programming module and "P" is used to enter it. All of the subsequent programming steps follow the same procedure. The rear terminal labeled "PGM. DIS." must be disconnected from ground to gain access to programming. The following table lists the programming steps.

"Pro 9" - SERVICE OPERATIONS (Protected by access codes) 3 IMS FORMULA BATCHING APPLICATION STEAM PRESSURE MONITOR/DISPLAY APPLICATION An IMS is used to display the weight of the contents of a hopper used to formulate dry soap mixes. A hopper weighing 1100 lb. is required to produce batches of 600 lb. A total of 1700 lb. must be supported. Therefore, two 1000 lb., 350 W compression load cells are used. The sensitivities of the load cells are 2 mV/V and the excitation voltage is 10 volts, producing a signal output of 11 mV when the hopper is empty and 17 mV when full. The 20 mV input range is selected, and display resolution is 0.5 lbs. The load cells are connected to the IMS. Scaling procedure "PRO 1" is used by emptying the hopper and keying in a display value of "0.0" lbs. Then 600 lbs. of material is emptied into the hopper and "600.0" lbs. is entered. Scaling is completed, including compensation for the weight of the hopper. Batching is accomplished by wiring a switch to the remote input E1-CON of the indicator. As each ingredient is mixed in, its weight is displayed. The display can be re-zeroed by the switch, allowing the next ingredient to be mixed into the batch. When the formula is complete, the mixing hopper is emptied and re-zeroed, ready for the next batch. An IMS is used to monitor and display the steam pressure within an oilfired generating station. A pressure transducer with a 3 mV/V output over a 0 to 2500 psi range is used. The 5 volt excitation supply is selected, resulting in a 15 mV full scale output. The 20 mV input range of the IMS is used. After connecting the transducer, scaling is accomplished by entering into the "PRO-1" mode and entering in "0" psi when the line pressure is 0, and entering in the exact line pressure, when pressure is taken at full scale (@ 2500 psi). During operation, the tare function can be used to re-zero the display to compensate for small shifts in the transducer. The optional dual alarms are used as high/low pressure limit detectors. The indicator's max/min signal recording is used as an aid for unattended operation. The 4 to 20 mA retransmitted analog output drives a second, remotely located display and is also looped with a hard-copy chart recorder for process analysis.
