Pump Controls and Liquid Level Controls

PC-XXX-LLC-CZ / PC-XXX-LLC-GM SERIES

Liquid level control

Description

The PC-xxx-LLC-CZ and PC-xxx-LLC-GM series are liquid

level control relays used to control conductive liquid pumping

operations in a pump-up or pump-down application.The units

come in two different voltage ranges (see specs below).

The units have an adjustable sensitivity knob (4.7 k to 100 k ohms)

that is set according to the resistance level at which you want the

probes (sold separately) to sense the conductive liquid.The units

have a built-in debounce time delay that prevents the relay from

energizing if the probe resistance momentarily goes above or

below the sensitivity setpoint (due to liquid splashing in the tank).

The units operate their internal relay based on inputs from a high

and low probe and a common reference (when a conductive tank

is used) or common probe (when a non-conductive tank is used).

Features & Beneﬁts

FEATURES

BENEFITS

Debounce time delay

(2 seconds)

Prevents rapid cycling of the pump due to

turbulance in the tank

Adjustable sensitivity

(4.7 to 100 K ohms)

Allows user to ﬁne tune the sensing resistance

to prevent false tripping due to foam or debris

Dual probe design

(plus a common)

Allows user the ability to set the level

differential required
