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.
The PMR2 is a direct replacement for Xylem-Flygt MiniCas product part numbers 14-407129, 14-407113, 835848, and 835857. The PMR2 performs both Motor Over Temperature and Seal Leakage Monitoring in one unit, can be powered by 120 VAC, 24 VAC, or 24 VDC, has relay contacts rated for 8 Amps at 120 VAC, 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 PMR3 performs both Motor Over Temperature and Seal Leakage Monitoring in one unit. The PMR3 is powered by 230 VAC, with relay contacts rated for 8 Amps at 230 VAC, and comes in a white case. The PMR3 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.

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 and 4. When the High ...
