Faults

The following chapter describes possible causes of faults and the work needed to rectify them. Should faults occur frequently,
shorten the maintenance intervals in line with the actual loading on the unit.
Contact the manufacturer with any faults that cannot be rectified using the following information.
Behaviour in the event of faults
The following applies:
1. Immediately switch off the unit with faults that pose an immediate danger to persons or property!
2. Determine the cause of the fault!
3. Switch off the unit and prevent it from being reconnected if rectifying the fault requires work in the hazard area. Immedi-
ately advise a supervisor on site about the fault.
4. Either rectify the fault yourself or have it repaired by authorised personnel, depending on the nature of the fault.
The Fault table [} 38] provides information on who is authorised to rectify and remedy faults.

No power supply.
Electrical cable not connected or incorrectly con-
nected.
No request from controller, hence fans switch
off.
