8.5.1
Avoidance of damage to rolling bearings during stoppages
Extended stoppages at the identical or almost identical resting position of the rotor in the rolling
bearings can result in damage, such as brinelling or corrosion.
• During stoppages, regularly start up the machine for a brief period once a month. As a
minimum, turn the rotor several times.
If you have uncoupled the machine from the driven machine and secured the rotor with a
rotor shipping brace, then remove this before turning the rotor over or starting up the
machine.
Make sure that the resting position of the rotor after the rotor has been turned over is
different from its previous position. Use the fitted key or the coupling halves as reference
markers.
• When recommissioning, carefully comply with the information in Chapter "Commissioning
(Page 67)".
8.5.2
Decommissioning the machine
• Record the decommissioning steps. This log will be useful upon recommissioning.
• If the machine is going to be out of service for longer than six months, then take the
necessary measures for preservation and storage. Otherwise, the machine could be
damaged as a result of not being operated.
8.5.3
Re-commissioning the machine
When you re-commission the machine, proceed as follows:
• Study the record made when the machine was decommissioned, and reverse the measures
that were taken for conservation and storage.
• Perform the measures listed in Chapter "Commissioning (Page 67)".

8.6.1
Inspections in the event of faults
Natural disasters or unusual operating conditions, such as overloading or short circuit, are faults
that overload the machine electrically or mechanically.
Immediately perform an inspection after such faults.
Correct the cause of the fault as described in the respective remedial measures section. Repair
any damage to the machine.
