Automatic tank filling...
The LC-3 liquid level controller will automatically cycle your pump or solenoid to keep your tank at the proper level. Install your own float switches and just plug in AC power. 15A relay will control pumps up to 3/4HP @120VACor 2HP@208V.
For filling applications, the level controller turns on your pump to fill the tank when liquid level drops to the "low level control float". When the liquid level rises to the "high level control float", the relay opens to shut off your pump. The cycle repeats automatically as needed to properly control liquid level. Can be switched from tank filling to tank emptyting with a jumper setting on the circuit board.
Emergency Level Alarm Included
If there is a problem that causes the liquid level to rise above the high level-control float, a third "emergency" float causes an alarm with a flashing beacon LED and loud warbling buzzer that can be heard through any industrial plant noise. The emergency alarm float is also a redundant relay shutoff. When the button is pushed the buzzer silences while the beacon LED continues to flash. The default setting is to have the buzzer sound again every 30 minutes until the condition is corrected. Everything resets automatically when the level is corrected.
Suitable for lift pump chambers, sump pump basins, holding tanks, sewage, agricultural and other applications. If an alarm condition occurs, the horn sounds and red alarm beacon activates.
