Description –

The Controller compares the 4/20mADC Level signal to an adjustable on and off setpoint. The Controller contact closure output connects to the Supervisory Transmitter which is connected to a dry wire pair. The Supervisory Transmitter transmits the signal to the Supervisory Receiver. The Supervisory Receiver receives and converts the signal to a dry contact closure which is used to operate a pump starter.

The Supervisory Receiver accepts a pump running contact and transmits it back to the Supervisory Transmitter. The Supervisory Transmitter provides a contact output that is used to operate Pump Status indicators. This application is used to maintain a level in a tank. Also, the Supervisory Transmitter will turn both Pump Status indicators on in the event there is a communication fault.
