Function

The product compares the input signals with the Set Point selected by the user. It then changes its output signal to control the water

level in the boiler or tank.

Inputs

The product has two inputs to accept the following signals:

-

Levelprobeortransmitter1-6Vor4-20mA.

-

A 1 K potentiometer input ~ for Valve Motor Drive (VMD).

Outputs

The output control signal can be configured / wired to work with a pump or a modulating control valve. It also provides two relay outputs

for high or low level alarms and can provide an isolated 4 - 20 mA retransmission output.

Other features:

-

An additional filter can be selected to increase the damping effect for turbulent conditions.

-

Commissioning parameters are protected with a pass code.

-

The LC2250 can communicate via an infrared link between adjacent controllers. It enables the parameters to be passed to a product

fitted with RS485 (User). The LC2250 is designated as a slave unit – no set-up or adjustment is needed.

Important: Do not cover or obstruct the infrared beam between products.
