Fault finding list
Troubleshooting
Equipment is not working
Fault:
Failure of power supply, no function.
Remedy:
Check voltage supply and all electrical connections.
Fault:
Electronic insert is defective.
Remedy:
Replace terminal box and electronic insert.
The equipment signals a malfunction
Error code:
E.01.
LED-Anzeige:
LEDs 1, 3 and 5 are illuminated.
Fault:
Lines leading to the resistance thermometer are short-circuited.
Remedy:
Check connections of the resistance thermometer (electronic insert, terminal lugs
P 6/7 + P 10/11). If necessary replace the resistance thermometer.
Error code:
E.02.
LED display:
LEDs 1, 3 and 5 are illuminated.
Fault:
Lines leading to the resistance thermometer are interrupted.
Remedy:
Check connections of the resistance thermometer (electronic insert, terminal lugs
P 6/7 + P 10/11). If necessary replace the resistance thermometer.
Error code:
E.03.
LED display:
LEDs 1, 3 and 5 are illuminated.
Fault:
Short circuit in measuring electrode.
Remedy:
Check connections of the measuring electrode (electronic insert, terminal lugs
P 4/5 + P 8/9). If necessary replace the conductivity switch.
Error code:
E.04.
LED display:
LEDs 1, 3 and 5 are illuminated.
Fault:
Interruption in measuring electrode.
Remedy:
Check connections of the measuring electrode (electronic insert, terminal lugs
P 4/5 + P 8/9). If necessary replace the conductivity switch.
Equipment gives inaccurate readings
Fault:
The indicated conductivity value exceeds the reference reading.
Remedy:
Change correction factor (Parameter:3 Correction of measured value) and, if necessary,
temperature coefficient (4.1 TK).
Fault:
The indicated conductivity value is below the reference reading.
Remedy:
Change correction factor (Parameter:3 Correction of measured value) and, if necessary,
temperature coefficient (4.1 TK).
Fault:
Adaptation of the measured value by changing the correction factor or the temperature
coefficient not possible.
Remedy:
Remove the conductivity switch and clean the measuring electrode.
