3 Turn potentiometer (B) slowly clockwise until the relay output
switches and the yellow control lamp changes condition
4 Turn the potentiometer approximately 15° in the same direction
If the relay output has switched, empty the vessel until the electrode is
uncovered.
The relay output must now switch again.
Note:
A failure exists, if the relay output does not switch over even in the last
range. You will find instructions for fault rectification in chapter
"M
aintenance and fault rectification".

Fig. 128: Slide switch (E) for setting the switching delay
The adjusted switching delay refers to the switching function of the
relay and applies only to the switch on delay.
Note:
When carrying out switching point adjustments keep in mind that there
is a switching delay of 0.5 sec between the moment when the
switching point is reached and the moment when the switching
function is triggered. The potentiometer must therefore be turned
slowly.
A possible additional switching delay should only be switched on after
the adjustment.
The following switching delays can be selected with the 3-step switch.
