8.6.1 Avoidance of condensation or formation of condensation within the machine
● If the controller does not do this automatically, switch on any anti-condensation heating
during stoppages. This will avoid the formation of condensation.
● Do not switch on the anti-condensation heating for at least two hours after the motor has
been switched off. This prevents damage to the winding insulation.
8.6.2 Avoidance of damage to roller bearings during stoppages
Extended stoppages at the identical or almost identical resting position of the roller bearings
can lead to damage such as brinelling or formation of corrosion.
● During stoppages, regularly start the machine up for a brief period once a month, or at least
turn the rotor over 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 the machine
up.
Make sure that the resting position of the roller bearings after the rotor has been turned
over is different from what it previously had been. Use the fitted key or the coupling halves
as reference markers.
● During re-commissioning, refer to the information in the "Commissioning" section.
