7.1.1.1
Visual inspection
Perform a visual inspection monthly by:
Checking the enclosure, cable entries and cables for damage.
Checking the screwed connections for tight fit.
7.1.1.2
Regular maintenance
No solvents should be used to clean the Ex p relay as these can impair the
properties on contact with the seals.
In the case of anomalies, the operator should weigh up the possibility of a timely
and proper cleaning by BARTEC GmbH against a spontaneous failure of the Ex p
relay.
Furthermore, the function of the overall system should be checked. The correct
function (safe separation of the power supply to the Ex p equipment) should be
checked.
Repairs
Repairs to the control unit and accessories may only be made by BARTEC GmbH.
Faults and troubleshooting
ATTENTION
AN ALTERED OPERATING BEHAVIOUR CAN BE AN INDICATION OF ALREADY
EXISTING DAMAGE TO THE CONTROL UNIT.
Only put the Ex p system back into operation after the cause of a
fault has been rectified.
It is assumed that all external electrical and mechanical equipment has been
properly connected. Therefore, the correct installation and connection of the
electrical devices should be checked first.
