OTT PLS - Information on Repair; Technical Data

How to join the plug-in connection:
䡵 If necessary: dry and clean the connector, pressure probe and protective cap*.
䡵 Take the protective cap off the connector and the pressure probe.
䡵 Check the O-ring on the pressure probe for damage and correct seating.
Replace O-ring if necessary* (spare par
t - temporarily cover the thread with
adhesive tape before replacement: danger of damage to the O-ring)
䡵 Carefully put the connector onto the pressure probe, taking note of the
coding lugs.
䡵 Hold the pressure probe tight and turn the connector clockwise as far as it
goes. Do not use a tool for this! There must be no gap between the connector
and the pressure probe.
* After cleaning/replacing the O-ring, regrease the interior of the plug-in connector (thread/sealing
surface/O-ring – omitting contacts) with suitable, standard grease for NBR materials (petroleum-based)
6 Information on repair
In the case of a device fault, particularly with variable measurement values and
measurement drift, please send the complete device including the pressure probe
cable for repair. A reliable fault diagnosis is only possible if both units are present.
