Short-circuiting the motor terminals
• The motor terminals of the synchronous lift machines, type WSG, can be short-circuited, if required, to brake
the lift machine faster.
• However, this is only permissible at speeds less than or equal to the rated speed of the respective motor.
PTC thermistors
The maximum operating voltage of the PTC thermis -
tors is not allowed to exceed 25 V DC
To achieve the maximum precision, the
measurement voltage per PTC thermistor must not
exceed 2.5 V DC.
Cable cross-section required:
