The Pump Monitoring Relay (PMR1) performs both Motor Over Temperature and Seal Leakage Monitoring in one unit. The PMR1 is powered by 120 VAC, with relay contacts rated for 8 Amps at 120 VAC, and comes in a white case. The PMR1 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, the reset pushbutton, and the adjustment potentiometer.

N/A
The PMR1 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. The PMR1 has two mounting options and comes with an 11 pin reverse socket for dead front mounting. |
