GENERAL NOTICES/MAINTENANCE
For your own safety and the safety of your monitored appliances the function
needs to be checked regularly.
The Water Level Switch does not need maintenance. When constantly used
there is the danger that the sensor tips may become dirty. Therefore, it is nec-
essary to check and clean the sensor on a regular basis. As with every security
device, regular service needs to be made. This should be on a monthly basis. To
check the function, the sensor needs to be activated with water or a conductive
metal.
MAINTENANCE AND HANDLING
The Water Level Switch is a maintenance free device. Only the electrodes of the
sensor should be checked and cleaned occasionally if the sensor is in constant
use. To ensure a reliable monitoring the function should be tested approx. once
a month, as usually done with all safety devices. To do this, short circuit the pins
at the tip of the sensor with a piece of metal or a drop of water. The switching
of the relay should be heard and the red LED
“
Rel. Ein
”
should light up.
