Malfunction without error-no.
In some cases, it will be technically impossible to display an "irregular functioning" of the installation
by a definite error number. An alleged error may by all means also be due to "correct" causes.
For this reason the list shown hereafter has been established, which contains the probable or
already encountered irregular functioning, their possible causes as well as the corrective action
(error elimination) to be taken.
Malfunction
Analysis
Possible causes
Remedy
Drive unit fails to react:
• No automatic opening.
• No reaction on the
control elements (side
cover/D-Bedix).
• LED 5 V (green) on the
control is not lighted.
Power supply voltage is
missing.
• Measure the mains supply
voltage, check its cabling and
eliminate any detected
deficiencies.
Drive unit fails to open.
• LED SE (safety element,
yellow) is lit.
• Determine the active safety
element via the diagnostic
level.
One or more safety
elements are active or
incorrectly cabled.
• Remove the obstacle.
• Check the cabling between the
safety element and the control
unit, and eliminate any detected
deficiencies.
• Replace the safety element.
• LED SE (safety element,
yellow) is not lighted.
• LED OE (opening command,
blue) reacts to the opening
element.
• Determine the opening
element via the diagnostic
level.
Depending on the enabled
operating mode, the opening
commands (inside/
outside, etc.) are ignored.
• Change the operating mode.
• Correct the cabling of the
opening elements.
• LED SE (safety element,
yellow) is not lighted.
• LED OE (opening command,
blue) is not lighted despite the
active opening element.
The opening command is
not evaluated.
• Check the cabling between the
opening element and the control
unit and eliminate any detected
deficiencies.
• Replace the opening element.
Drive unit fails to close.
• LED SE (safety element,
yellow) is lit.
One or more safety
elements are active or
incorrectly cabled.
• Remove the obstacle.
• Check the cabling between the
safety element and the control
unit and eliminate any detected
deficiencies.
• Replace the safety element.
• LED SE (safety element,
yellow) is not lighted.
• LED OE (opening command,
blue) is lit.
An opening command is
pending.
• Check the cabling between the
opening element and the control
unit and eliminate any detected
deficiencies.
• Replace the opening element.
• Check the operating mode.
The operating mode OPEN
is active.
• Change operating mode.
The operating mode
cannot be changed.
• The program switch in the
side cover fails to react.
Program switch cable is not
plugged in.
• Check the cable and eliminate
any detected deficiencies.
• The operating mode symbol
on the display is underlined.
The operating mode is
overridden via connection
terminal X110.
• Change the operating mode by
means of the external program
selector switch.
• Correct the cabling of the
external program selector switch.
Prior to commissioning:
During manual opening,
the door leaf encounters
an important resistance
and closes at high speed.
The motor connector plug
is not connected.
• Plug the motor connector plug
into the socket
