8.8 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.
Measures for machines ready to operate during longer non-operational periods
● For longer periods when the machine is not being used, either energize it at regular intervals
(roughly once a month), or at least spin the rotor.
● Please refer to the section"Switching on" before switching on to recommission the motor.
NOTICE
Damage due to improper storage
The
machine
can be damaged if it is not stored properly. If the motor is out of service for
extended periods of time, implement suitable anti-corrosion, preservation, and drying
measures.
When recommissioning the motor after a long period out of service, carry out the measures
recommended in the chapter entitled "Commissioning".
8.8.1 Switching on the anti-condensation heater
If the machine has anti-condensation heating, then switch it on when the machine is not in
operation.
● If the controller does not do this automatically, switch on any anti-condensation heating
during stoppages. This will avoid the formation of condensation.
●
Observe the specifications on the anti-condensation heating plate in this regard.
WARNING
Explosion hazard
If the
anti-condensation heating is switched on directly after the machine is switched off, the
temperature class or the maximum surface temperature of the machine can be exceeded.
In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious
injury or material damage.
● Only switch on the anti-condensation heating after the motor has been switched off.
Carefully comply with the data on the anti-condensation heating plate.
