All fault codes can be reset manually by switching On/Off the CS (cabin switch)
.
Fault codes
F0-F7 and U0-U7 are reset automatically if the function in question is running (function verified).
Fault codes L and H are reset automatically if the battery voltage becomes correct. Fault code E
is reset automatically if the control system has not received any signal from the relevant control
device for 6 minutes.
Example of sequence of fault codes:
Output No. 3 short-circuited.
9.1.3
Supply voltage
A supply voltage of between 8.0V and 15.0V is regarded by the unit as correct for a 12V system.
A supply voltage of between 18.0V and 29.0V is regarded by the unit as correct for a 24V sys-
tem.
All functions on the unit cease when the supply voltage is less than 7.0V. If the supply voltage
then rises to more than 7.0V, functionality is restored.
Control device 1 (together with 2h1 on certain models) allows emergency operation of the lift at
voltages down to 7V or 16V. This takes place at your own risk and only works for a limited time,
after which an idle period is required.
