Electric wire rope winch BETA EL
English
4.5 Project Planning Help for Control Construction
For delivery of a rope winch without electronic control (without electronic overload
protection)
The electronic control is developed and produced by the operator under his responsibility. This makes
the producer of the electronics control the overall lifting gear producer according to the European Ma-
chinery Directive.
To keep the lag of load as low as possible when lowering it, the connection of the solenoid magnet disc
brake MUST be interrupted on the direct-current side when the motor is shut down!
The deactivation time at direct-current side interruption by the switching contactor of the motor is about
1/3 of the deactivation time at alternating-current side interruption. This means that the braking dis-
tance for stopping of the load is much shorter at interruption of the brake control by the respective
switching contactor on the direct-current side than in case of alternating current deactivation!
Connection of the brake rectifier for direct-current side deactivation of the brake
(short braking distance)
>Delivery condition<
Remove jumper A at the brake rectifier
during commissioning!
For more information on the setup of the electric control, see circuit diagram in the
operating instructions! Observe the included operating instructions!
