In the event of faults during start-up or operation,
first check the following
points;
Mains power available?
Emergency stop pushbutton unlatched?
Program switch in the correct position?
Light barrier transmission
paths clear and light barriers clean?
Door obstructed?
Door panels easy to move (counter-roliers,
floor guides)?
Fuse OK?
All external activators,
emergency stop switches, program switches and locks correctly wired?
All plugged connections
firmly
in place?

For connection of the interconnecting
cable, completely open the corresponding terminal
by
unwinding the
ill
screw in a counter-clockwise
direction.
Insert the wire and tighten the screw.
For installation
work, remove plugs 11/12113 in order to disconnect
the control unit.
If the fault should not be remedied
by any of the above, use the hand terminal
(HO) for fault analysis. Further aids
are provided by the diagnostics
display on the expansion module and the information
for fault rectification
given in
the following
table.

Response of control units in the event of a short circuit.
•
The 24V power supply for radar detectors, electro. mechanical
locks and the motor connection
are of short-circuit-proof
design.
In the event of a short circuit,
the power supply unit interrupts
all secondary voltages and the operating
status
display is extinguished.
After rectification
of the short circuit,
the power supply unit does not automatically
switch on again! Remove pains plug, wait approx. 3 seconds and then re-insert mains plug.
