MAINTENANCE

Replacement of sensing probe
The EE22 series are transmitters with interchangeable sensing probes and connectors.
If the sensing probe gets damaged (e.g. mechanical destruction of the sensor probe) it is
possible to replace the probe without re-adjustment.
Procedure of replacement:
1) Switch off supply voltage
2) Remove damaged sensor probe
3) Plug in the replacement probe
Attention: Do not mix up the position of the probes!
(see chapter 3.1 “Mounting of the probe”)
