Input and output properties If liquid level exceeds limit: When K1 is set to OFF state, output relay is energized, with yellow LED ON. When K1 is set to ON state, output relay is de-energized,with yellow LED OFF. When LFD enabled, output relay 1 is de-energized,with yellow LED OFF and red LED flashing; output relay 2 is energized, with yellow LED ON.
Switch setting function A 430kΩresistor should be paralleled between electrodes when using LFD functing. NO means terminals 6,8 and 3,5. NC means terminals 6,7 and 3,4. The switches are set to OFF state by default.
