Electrical faults
Current active fault messages are briefly displayed cyclically (10 sec.) at the display
program switch during operation. In addition, they are also entered in the
e®
and
Oe
fault memories.
If the dot lights up in the left half of the program display selector screen, then the
installation was unable to completely initialise.
Either there is an obstruction or something in the installation itself has become
jammed.
The dot disappears as soon as the door has been opened completely and closed
again once.
If no fault is indicated during a malfunction or if the display program switch is not
functioning:
➮
Check whether the power supply is connected.
➮
Check cables and cable connections.
➮
Check fuses in the controller and transformer, and replace if necessary (see
below).
For troubleshooting and elimination, see the fault table.
