Excessively high machine temperature when heating is switched on
If the anti-condensation heating is operated while the machine is running, this can increase
the temperatures inside the machine. Material damage can result.
● Make sure that the anti-condensation heating is switched off before the machine is switched
on.
● Only operate anti-condensation heating when the machine is switched off.
8.3 Stoppages
The stoppage is a shutdown for a period of time, during which the machine is stopped but
remains at the location of use.
Under normal ambient conditions, e. g. the stopped machine is not exposed to any vibration,
no increased level of corrosion, etc. in general, the following measures are necessary during
stoppages.
8.3.1 Prolonged outage periods
If the machine is out of operation for longer than one month, start up the machine regularly,
that is, approximately once a month. Alternatively, as a minimum, turn the rotor.
If the machine is to be taken out of operation for more than 12 months, suitable anti-corrosion,
preservation, packaging, and drying measures must be taken.
