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?

A\

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

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.
