Commissioning
7.2 Measures before start-up
Measures
Once the system has been correctly installed, you should check the following prior to
commissioning:
● The machine has been assembled and aligned correctly.
● The machine has been connected so that it rotates in the direction specified.
● The operating conditions match the data specified on the rating plate.
● The bearings have been lubricated as appropriate for the version used. Rolling-contact
bearing machines which have been in storage for more than 24 months have been
relubricated.
● Any supplementary machine monitoring equipment has been connected correctly and is
functioning as it should.
● For versions with bearing thermometers, the bearing temperatures must be checked
during the machine's first period of operation. The warning and shutdown values are set
on the monitoring device.
● Appropriately configured control and speed monitoring functions ensure that the machine
cannot exceed the permissible speeds specified on the rating plate.
● The output elements have the correct settings for their type (e.g. alignment and balancing
of couplings, belt forces in the case of a belt drive, tooth forces and tooth face clearance
in the case of toothed-wheel power output, radial and axial clearance in the case of
coupled shafts).
● The minimum insulation resistance and minimum clearance values have been adhered
to.
● The grounding and equipotential bonding connections have been established correctly.
● All fixing screws, connection elements, and electrical connections have been tightened to
the specified torques.
● Lifting eyes that were screwed in have been removed following installation or secured to
prevent them becoming loose.
● The rotor can turn without coming into contact with the stator.
● All touch protection measures for both moving and live parts have been implemented.
● In cases where the shaft extension is not being used and is, therefore, exposed, it has
been covered and the feather key has been secured to prevent it from being thrown out.
● If being used, the external fan is ready for operation and connected so that it rotates in
the direction specified.
● The flow of cooling air is not obstructed.
● If a brake is being used, it is functioning correctly.
● The specified mechanical limit speed n
70
is adhered to.
