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. |
