7. Commissioning and operating
7.1. Important notes
DANGER
f
The commissioning may only be carried out by trained and qualified personnel with professional knowledge of
electrical engineering and lift construction.
f
Check that all live connection points are safe against accidental contact.
f
During commissioning, unintentional movements of the traction sheave may occur. Make sure that, even if the
motor starts to move unintentionally, no danger can result for personnel or machinery.
Before starting up the motor the following points must be checked:
•
Check that all performance and application data specified on the name plate of the machine are consistent
with your application.
• Have all securing, auxiliary and installation tools been removed from the danger area?
•
Check if the lift machine is being used for its intended purpose – comply with the permissible ambient
conditions.
•
Check if the lift machine has been properly fastened with the fastening bolts – have all the bolts been
tightened to the specified torque and secured?
•
Has the motor been properly connected, including the motor protection? Has the PE terminal been properly
connected? Is the potential equalisation with the machine frame ensured?
•
Check the proper functioning of the temperature monitoring devices (e.g. by interrupting the temperature
monitoring circuit).
• Has the measuring system been properly connected?
• Check the brake connection and the proper functioning of the brake monitoring switches.
•
Ensure that the brake operates correctly; perform a brake test using one partial brake.
•
Has the rope slip-off guard been tightly fastened and properly adjusted?
Information
f
An initial function test of the motor and the brake, together with the inverter, should be performed before the ropes
are put in place.
f
If the motors are being operated at no shaft load (no ropes put in place) for an extended period of time, abnormal
noise may occur resulting from the bearing type used.
Half-load test
Information
f
If the motor winding is short-circuited with the control system deactivated, a speed-dependent braking torque will
be produced, even at low speeds. Therefore, the short-circuiting should be deactivated during the half-load test. It
is imperative for it to be reactivated after the test.
