The LC1350 input options are:

-

High alarm or low alarm from a conductivity probe.

-

Pump on/off control from two conductivity probes.

Function / outputs

The controller reacts to a change in probe conductivity (open /closed circuit) and energises / de-energises a relay. This action switches

a pump or sounds an alarm.

Other features:

-

Additional filters can be selected to increase the damping effect for turbulent conditions.

-

To prevent unwanted or inadvertent changes being made, all commissioning parameters are protected with a fixed pass code.

-

The product can communicate via an infrared link between adjacent boiler house controllers. It is designated as a slave unit.

-

A panel mounted external test switch may be fitted if required.
