Visual inspection
Perform a visual inspection every month:
Check the enclosures, cable entries and cables for any damage.
Check if the screw connections are mechanically secured.
Check fault memory for any contents.
Cleaning
Solvents should not be used to clean the control unit, as these can impair its
properties if they come into contact with seals.
Regular maintenance
Depending on the purity of the purge air used, the inlet and outlet of the control
unit must be inspected regularly for any contamination (e.g. oil, dust, etc.) or
corrosion.
In the event of any abnormalities, the operator should weigh up the possibility of
a timely and appropriate cleaning at BARTEC GmbH against a spontaneous
failure of the control unit.
Furthermore, the function of the entire system should be checked. In this regard,
the correct sequence of the purging phase and operating phase should be
checked.

Repair work
Any repairs to the control unit and the accessories may only be carried out by
BARTEC GmbH.
