Please check following points, if the smoke vent system fails to function satisfactorily or the green control LED in the button fails to lighten. Diagnosis must be
carried out in following order: 1st supply plug-in card VE, 2nd line plug-in card LE, 3rd group plug-in card GE, 4th window lock plug-in card AE, 5th smoke
detector and external control. Detected faults must be eliminated at once before the diagnosis is continued!
Trouble shooting
To test the function of the earth fault checkup, the diagnosis pins on the VE must be bridgeover.
If the LED does not light, it might be necessary to check the grounding and connect it correctly.

Remedy
Eliminate earth fault.
Check accumulator, connection and fuse.
Call in-house electrician immediately for eliminating
power failure.
Connect line.
.
1. Bridge diagnostic pin against middle pin on line
plug-in card.
Check fuse, connections, cables, t ,
clamps, smoke detectors and external control.
2. Bridge diagnostic pin against middle pin on line
plug-in card.
Check fuses, connections, cables, terminal resistors,
terminals and smoke vent buttons.
Check fuses, connections, cables, and t
on drive.
Check t or terminal module between
terminal and .
Check t or terminal module between
terminal and .
.
1. Bridge diagnostic pin against middle pin
on plug-in card
Check fuses, connections, cables, t ,
terminals, smoke detectors and external control.
2. Bridge diagnostic pin against middle pin
on plug-in card.
Check fuses, connections, cables, t ,
terminals and smoke vent buttons.
Check fuse, terminals and loop resistance.
Exchange detector.
Exchange detector.
In case of repetition, disconnect contact.
Search for fault in external system.
Disconnect temporary perhaps, so that the
smoke vent remains operative.
Search for interruption; check whether
contact in external system is really closing.

Detector is dirty or faulty.
Defector is faulty or wrong type.
External system gives possibly only short
contact by malfunction or has given alarm or
false alarm and has been unknown reset
again.
Ensure, that contact in external system is
opened. If external alarm is not resettable by
malfunction, search there for malfunction.
Main contact is not closing
