The ATC Diversified LPC Series Liquid Level Pump Controller is a conductive liquid level controller that uses two probes to sense tank level. There are two modes of operation that are user selectable:
Drain (Pump Down): The output relay of the LPC Series Liquid Level Pump Controller will pick-up and the LED will turn on when the liquid level reaches the high level probe. When the liquid level falls below the low-level probe the relay will drop-out and the LED will turn off.
Fill (Pump UP): The output relay of the LPC Series Liquid Level Pump Controller will pick-up and the LED will turn on when the liquid level falls below the low-level probe When the liquid level reaches the high-level probe the relay will drop-out and the LED will turn off.
