- Family: LIQUID LEVEL CONTROL RELAY
- Function: SINGLE PROBE PUMP DOWN
- Sensitivity Range: Sensitivity Range: 1K - 250K Ohms
- Timing Range: Fixed at 4 Sec.
- Control Voltage: 240V AC
- Output: 10A SPDT
Pump Down (Drain): When the liquid level rises & touches 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 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 & the LED is Green ON until the liquid level rises & touches the probe.
- Voltage Tolerance: AC Operation: +10/-15% of nominal at 50/60 Hz.
- Load (Burden): 2 VA
- Indicator LEDs: Green ON with Input Voltage applied; Red Flashing during timing; Red ON when relay energized.
- Probe Voltage: 5V DC Pulsed
- Response Time: Pick-up: Fixed per value shown under "Function" in table above; Drop-out: 500ms
