Assembly and Operating Manual

*If the green control light lit is not lit, check the following points
(only on machines with 400 V drive):
−
Is there a phase failure?
−
Is the phase sequence incorrect?
−
If the phase sequence is incorrect, correct it
on the phase inverter (1) (power supply
plug) by turning the two plug pins 180°
using a screwdriver.
−
Is the trailing cable connected to the trolley?
−
Are the fuses in the ground-station switch box serviceable?
Motor does not produce full power:
−
Voltage drop of more than 10% of the rated voltage.
−
Select supply cable with larger cross-section.
−
If overloaded, the integrated thermal switch turns off the control
current. Work can continue after a certain cool-down period (possibly
reduce load).
Refrain from repeated overheating/overloading. - Otherwise the
service life of the motor/brakes will be shortened.
