7.3 Monitoring of the bearing temperature in the event of a fault
WARNING
Shutdown of the machine caused by increased bearing temperature in the event of a fault
Standstill of the machine in the event of a fault can lead to death or physical injuries.
In the event of a fire/fault, machines must fulfill their function irrespective of the bearing
temperature.
Switch off the protection equipment for monitoring the bearing temperature in the event of a
fault.
NOTICE
Damage to the machine
In order to avoid material damage, check the following points before commissioning the
motor:
•
Using appropriate measures, check whether the correct direction of rotation of the motor
has been set by the customer, e.g. by decoupling from the driven load.
•
Ensure that temperature-sensitive parts (cables, etc.) are not in contact with the
machine enclosure.
• Ensure that the condensation drain holes are always located at the lowest part of the
motor.
NOTICE
Damage caused by insufficient cooling
Effective cooling is no longer possible if air guidance of the machine is not provided as
intended. This can damage the machine.
•
Before commissioning, attach the covers to guarantee the intended air guidance.
Measures
Once the system has been correctly installed, you should check the following prior to
commissioning:
● Ensure that the machine has been correctly installed and aligned.
● Connect the machine corresponding to the specified direction of rotation.
● Ensure that the operating conditions match the data specified on the rating plate.
● Lubricate the bearings, depending on the version. Ensure that machines with roller
bearings, which have been stored for longer than 24 months, are relubricated.
Also observe the notes in Chapter Preparation for use.
● Ensure that any optional supplementary machine monitoring equipment has been
connected correctly and is functioning as it should.
