•
Device does not switch:
- Check whether the control voltage is correctly applied to terminal A1, A2 and corresponds to the voltage
specification on the name plate.
- Check whether the electrodes are connected correctly.
•
Device switches although the electrodes are not wetted:
- Check if electrodes are bridged by moisture film or foam
- Cable capacity too high
Error can usually be corrected in both cases by selecting a less sensitive setting (turn Poti R
liquid
to the left)
When the device is switched on or when the program is changed, the following is displayed by rapid flashing
of the yellow LEDs:
•
The K1-K4 displays the active program number
(e.g. K4 flashes for program 1).
•
The displays E1-E4 show the software status.
The display is binary, i.e. read from left to right: 8 - 4 - 2 - 1
If all four relay LEDs (K1 - K4) and two red LEDs (E1, E4) flash, no valid program is selected. Check the
switch position of the DIP switches.
→ In the case of other errors, send in the device with error information for review.
