Automatic tank filling...

The pump-down controller will automatically cycle your pump to keep your tank filled. When the liquid level drops to the bottom float switch, the LC-2 Pump Controller turns on your pump to fill the tank. When the liquid level rises to the high level float, the relay opens to shut off your pump. The cycle repeats automatically as needed to properly maintain your liquid level.

The liquid level controller can easily work the opposite way as a pump-down controller to empty tanks by removing a jumper 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.

The audio buzzer has a silence button that with a 30 minute snooze alarm if desired so the alarm won't be forgotten.

The Pump Controller is designed to be quickly installed and working in a few minutes with no tools. Simply mount it on your tank and adjust the depth of the high and low float with the thumb screws.

The high level pipe is 7 inches long and can be mounted from 2-7 inches below the threaded plug. The low level foat is selectable in 10 inch increments.
