8.5 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.
Longer non-operational periods
Note
● For longer non-operational periods (> 1 month), either operate the machine or at least turn
the rotor regularly, approximately once per month.
● Please refer to the section "Switching on" before switching on to recommission the motor.
● Remove any machine rotor locking devices before you turn the rotor.
NOTICE
Restricted motor function
If not used for longer periods of time, material damage or complete motor failure can occur.
If the motor is out of service for a period of more than 12 months, then environmental effects
can damage the motor.
● Apply suitable corrosion protection, preservation, packing and drying measures.
Switching on the anti-condensation heater
Switch on any anti-condensation heating while the machine is not being operated.
Taking the machine out of service
Details regarding the necessary measures, Chapter Preparing for use (Page 27).
Lubricating before recommissioning
NOTICE
Dry running bearings
Bearings can be damaged if they do not have sufficient grease.
● Re-grease the bearings if they have been out of service for more than one year. The shaft
must rotate so that the grease can be distributed in the bearings. Observe the data on the
lubricant plate.
