
Adaption of the electrodes to the operating conditions in case of type “Universal”
The electrodes of the electronic level control Universal must be shortened according to the desired activation
and deactivation points. A use of the level control with electrodes not shortened is not possible!
The adaption shall be effected as follows:

Disconnect the power supply before adaption

Fix the electrode holder to the pump and/or the tank wall.

The electrodes must be shortened as follows on the side without thread :

Shorten the earth electrode in such a way that the electrode is minimum 5 mm longer than the deactivation
electrode.

Shorten the deactivation electrode in such a manner that the electrode rises out of the water at the desired
deactivation point

Shorten the activation electrode in such a manner that the electrode dives into the water at the desired
activation point

Shorten the alarm electrode in such a manner that the electrode dives into the water at the desired alarm
point

Cut the protection hose at the lower end of the electrodes by approx. 5 mm after shortening.

The electrodes are screwed into the electrode holder (please respect the sequence according to indication
on the electrode holder)
