The Adjustable Transmitter is a device used in an analog current loop to test a 4-20mA Input, calibrate or demo equipment. The 4-20mA Current Simulator is a current simulator/loop simulator, which simulates an analog field device such as a Pressure Transducer or Temperature Transmitter. When placed in the analog current loop, the loop powered 4-20mA simulator regulates the current in the loop to the setting on the knob from 4 to 20 mA. When a more precise setting is required, place an ammeter in the current loop to display the loop current.
The BOAC is a device that performs the various task required to manage a 12VDC alarm system that has an alarm strobe light and horn that must be powered by a 12V backup battery. The BOAC charges the backup battery, provides a Power Loss Alarm (when required), has a repeat cycle timer for the horn, a system push-to-test button and indication of the battery charging mode.
During an alarm condition the alarm strobe light and horn are powered by the battery. After an alarm condition and with 120VAC applied/restored, the BOAC will recharge the 12V backup battery. During an alarm condition battery power is conserved by operating the horn intermittently, on for 2 seconds, and then off for 2 seconds.
The Pump Monitor Relay provides Motor Over Temperature and Seal Leakage alarms for Submersible Pumps.
Motor Over Temperature Alarm - The unit applies a low voltage DC signal to the Motor Thermal Sensor to check its status. If the unit detects that the Motor Thermal Sensor contacts are closed (normal condition), the Overtemp indication remains off, and the Overtemp Relay is energized closing the contacts between terminals 1 and 3.
If the Motor Thermal Sensor contacts open (Over Temperature condition), the Overtemp Indication is turned on and the Overtemp Alarm Relay is de-energized opening the contacts between terminals 1 and 3 and closing the contacts between terminals 1 ...

Pump Monitor Relay PMR1 The Pump Monitoring Relay (PMR1) performs both Motor Over-Temperature and Pump Seal Leakage Monitoring in one unit. The Seal Fail Relay is powered by 120VAC, with relay contacts rated for 8 Amps at 120VAC, and comes in a white case with an included socket.
The Over Temperature Relay has two mounting options with standard surface mounting or dead front mounting so that the dead front door need not be opened to see the status of the Seal Leakage condition and Pump Over-Temperature, as well as power indication, the Auto/Manual reset select switch, the reset pushbutton, and the adjustment potentiometer.
The Automatic Reset Seal Fail Relay applies a low voltage DC signal to the Motor Thermal Sensor to check its status, and uses a low voltage AC signal to measure the resistance between a single (or dual) Leakage Probe(s) and the grounded motor housing, or between two Leakage Probes to check for the Seal Leakage condition.
Pump Monitor Relay PMR2 The PMR2 is a direct replacement for Xylem-Flygt MiniCas product part numbers 14-407129, 14-407113, 835848, and 835857 and works with pumps using FLS and CLS sensors. The PMR2 performs both Motor Over-Temperature and Seal Leakage Monitoring in one unit, can be powered by 120VAC, 24VAC, or 24VDC, has relay contacts rated for 8 Amps at 120VAC, and comes in a blue case.
The PMR2 is dead front mountable so that the dead front door need not be opened to see the status of the Seal Leakage condition and Pump Over-Temperature, as well as power indication, the Auto/Manual reset select switch, and the reset pushbutton.
The PMR2 applies 12 VDC to the sensor and measures the current flow through the sensor. The sensor controls the current in the circuit. If the sensor current is in the normal range the Temperature Alarm Relay is energized to allow normal pump operation. If the sensor circuit becomes shorted, the 12 VDC is turned off and all LEDs flash. With the sensor current below the Trip Point, the Overtemp Indication is turned on. If the sensor current increases above the Trip Point, the Leakage Indication is turned on.

When power is applied, the power LED comes on. When a motor start signal is applied to pin 3, the middle LED comes on, showing that the 500 VDC is being applied to the motor winding. If the winding is good, the Automeg completes the megging operation, and the motor starts signal is then connected from pin 3 to 4.
If the winding is bad, the Low Meg LED comes on, and the motor start signal will not be available at pin 4 to engage the motor starter. To unlatch the Low Meg alarm contact, depress the Motor Reset pushbutton. The Low Meg Alarm contacts, pins 10 and 11, are a normally open relay contact that closes upon the Low Meg Alarm condition.
An Emergency Bypass Switch is provided to bypass the megging process. Placing ...
