Behaviour in cases of error

a simple error. Check the system for the listed sources of
error.
If the error cannot be removed after an inspection to the
named causes, then inform customer service or your deal-

especially on the safety devices, as

of the control window
6.1 Moving onto an obstacle
If the lifting rails or a lifting arm have been moved onto an
obstacle due to inattention of the operator, only the motor
is blocked for the lifting rail or lifting arm sitting on the
obstacle. The lift switches off as soon as the other lifting
rail has moved out of the control range of 64 mm. As an
additional safety measure, there is a temperature monitor
integrated into the motor winding which interrupts power
if the motor is overloaded. Any further operation of the
lift is only possible after some minutes have passed (cool-
ing of the motor: depending of the external temperature).
After a motor is blocked the v-belt must be checked for
any possible damage and exchanged if required. Please
contact your service partner (dealer).
