LCP1A100F1
Lead Time: 7 Days
Description Of Function
Pump Up (Fill): When the liquid level falls below the probe, a fixed time delay begins & the LED flashes Red. This time delay prevents rapid cycling of the output relay & its load. At the end of the time delay, the output relay energizes & the LED is Red ON. The pump is ON to fill the tank. The relay remains energized until the liquid level rises & touches the probe. The output relay de-energizes, turning off the pump, and remains de-energized & the LED is Green ON until the liquid level falls below the probe.

Operation
Pump Up (Fill): When the liquid level falls below the probe, a fixed time delay begins and the LED flashes Red. This time delay prevents rapid cycling of the output relay and its load. At the end of the time delay, the output relay energizes and the LED is Red ON. The pump is ON to fill the tank. The relay remains energized until the liquid level rises and touches the probe. The output relay de-energizes, turning off the pump, and remains de-energized and the LED is Green ON until the liquid level falls below the probe.
Pump Down (Drain): When the liquid level rises and touches the probe, a fixed time delay begins and the LED fl ashes Red. This time delay prevents rapid cycling of the output relay and its load. At the end of the time delay, the output relay energizes and the LED is Red ON. The pump is ON to drain the tank. The relay remains energized until the liquid level falls below the probe level. The output relay de-energizes, turning off the pump, and remains de-energized and the LED is Green ON until the liquid level rises and touches the probe.
If the container is non-conductive or insulated, an additional probe must be installed as the COM connection where it will always be submerged.
