PC 102 Enhanced Duplex Float Controller


The PC102-S is designed for the operation of two loads requiring alternation for the equalization of wear, where floats or pressure switches are the primary sensor.

The PC102-S is similar to the PC101-S with additional monitoring functions for hand/off/auto selector position and critical alarm inputs such as pump overtemperature, VFD fault, etc.

Operation differs from the PC101-S in that during a pump operation cycle, if a pump specific critical alarm occurs, then that pump is taken out of service. The non-operational pump started and a pump fault alarm is indicated.

Inputs are provided to allow the controller to monitor each pump’s H-O-A selector. Pumps will be called into the duty cycle only if their H-O-A is in the “auto” position.

All other features are the same as the PC101-S
