1 FUNCTION AND USAGE
CA 462 is a combined standalone leakage detection and temperature blocking
relay for DIN rail mount.
1.1 Function leakage
In case of water leakage, the resistance between the sensor electrode and hous-
ing will decrease. If the resistance becomes less than 100 kohm (±10 %) between
terminals 11 and 12, the relay contact on terminal 1 and 2 closes. The signal has
to be stable for at least 10 seconds before the relay is been activated.
1.2 Function Temperature blocking
If the temperature in the pump is rising and the terminal protector sets off, the
CA462 is blocking the pump without any delay.
Automatic reset
− if terminal 14 and 15 are open; pump starts automatically when the tempera-
ture is back to normal.
Manual reset
− if terminal 14 and 15 are bridged; manual reset has to be done by terminal 13
and 14 after the temperature is back to normal.

4.2 Cleaning
How to clean the unit
Powers off the unit and only outside/front shall be cleaned by using a dry, soft
cloth. A good choice would be the microber type of cloth and gently wipe the
CA 462 unit on front in order not to scratch the overlay. If the dry cloth did not
completely remove the dirt, do not press harder in an attempt to scrub it off. If
necessary, moisten the cloth by adding a small amount of water with thin solution
of mild detergent and try again. Never use detergent with polish or solvent which
can have an impact of the plastic surface.
