OPERATION

The LC-3 Level Controller will automatically cycle your pump to keep your tank filled, or empty if that’s how you set it. In tank-filling mode, 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 LC-2 shuts off your pump. The cycle repeats automatically as needed to properly maintain your liquid level.

To switch between to pump-down mode, simply remove a circuit board jumper.

EMERGENCY LEVEL ALARMS INCLUDED

If there is a problem that causes the liquid level to rise above the high level-control float, or fall below the low-control float, extra “emergency” floats causes an alarm. This alarm is given with a flashing 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.

INSTALLATION

The LC-3 Pump Controller has an electronics box that mounts on the wall.  The adjustable level probes are  quickly installed and working by adjusting the depth of the high and low float with the thumb screws.  The standard high level pipe is 8 inches long. The low level float pipe is selectable in 10 inch increments. Each pipe is adjustable for almost its entire length.  For example, a 20 inch long low float pipe can be adjusted from 2-20 inches working depth.  The standard communications cable length is 10 ft.

To connect your pump or solenoid, it comes with a convenient piggyback plug so you can simply plug in your pump directly.  Alternatively we can supply a solenoid valve as an option.
