Safety function failure
If a safety function fails, the equipment must not be operated until it is repaired.
Malfunctions
The chain hoist can only function when it is correctly connected to the power supply. In the event of a failure,
therefore, first check cables, strain relief and power supply connections. Malfunctions may also be caused by in‐
correct transmission of commands from the control pendant. Therefore, check the control pendant and the control
cable for damage and the plug-in connector on the pendant and in the service enclosure for correct fit.
The symbols are shown one after the other.
● Please contact our after-sales service if the cause of the fault cannot be eliminated with the given measures.
