Pump Controller

The PC-xxx-LLC-CZ is a liquid level control relay used to control
conductive liquid pumping operations in a pump-up or pump-down
application. The unit comes in two different voltage ranges. The model
PC-100-LLC-CZ is for 95-120VAC applications and the model PC-200­LLC-CZ is for 190-240VAC applications.

Model PC-XXX-LLC-CZ

Features:

• One unit serves pump-up and pump-down
applications

• Adjustable sensitivity knob (4.7 to 100K
ohms)

• Debounce time delay (2 seconds)

• Single or dual probe inputs (+ common

reference)

• Compatible with Crouzet’s PNR & PNRU
series liquid level control

• LED indicator

• UL508 listed

• CE marked

• 8-pin plug in; DIN rail or surface mount

• 5-year warranty

• Made in the USA

The unit has an adjustable sensitivity knob (4.7-100K ohms) that is
set according to the resistance level at which you want the probes
(sold separately) to sense the conductive liquid. The unit has a built­in 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 unit operates its 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).

Pump-up application: when the liquid level drops and the low probe
resistance increases above the sensitivity setpoint, the relay energizes

to run the pump and ll the tank. When the liquid level rises and the

high probe resistance decreases below the sensitivity setpoint, the relay
de-energizes to stop the pump.

Pump-down application: when the liquid level rises and the high probe
resistance decreases below the sensitivity setpoint, the relay energizes

to run the pump and empty the tank. When the liquid level drops and

the low probe resistance increases above the sensitivity setpoint, the
relay de-energizes to stop the pump.

The unit can also be congured to work with a single probe input and

a common reference (or common probe).
