2. Check the voltage supply.
3. Check all cables for pinching or shearing points.
4. Exchange the lifting module or the control unit (referencing necessary).

Interrupt the voltage supply for 30 seconds.
For distribution: Always switch on all control units
simultaneously!
Control unit in reference mode.
Perform the referencing.
Message disappears after short synchronization.
Interrupt the voltage supply for 30 seconds.
Push a button to reset the error.
If the error continues to exist, separate the control unit
from the mains for 30 seconds.
If this does not remedy the error, contact the service.
Push a button to reset the error.
If the error occurs without collision, reduce the
