TROUBLESHOOTING
O
Your device does not work.
w
Make sure that power supply output tension between terminals '–' and '+' remains between 17,5
and 18,5Vd.c. Otherwise, disconnect the power supply from the system and measure tension
again . If it is correct, there is a leakage in the system. Disconnect the power supply from the
network and check the system.
w
Make sure that terminal 'D' is not short-circuited to terminals '–' or '+'.
w
Make sure that terminal 'D' has not been exchanged with 'A' in a part of the system.
O
Audio volume inadequate.
w
Adjust audio levels following the instructions indicated on page 51. In case of feedback, reduce
the volume until it disappears. If the feedback disappears only by reducing volume to a
minimum level, probably another problem exists.
O
Persisting audio feedback
w
Make sure that terminal 'A' is not short-circuited to any other terminal and that it has been properly

Make sure that the connection has been carried out acccording to the type of door opener installed (see
page 57).
w
Make a short circuit between doorpanel terminals 'CV1' and 'CV2'; in this moment the value
between the door opener terminals should be 12Vd.c. or a.c. (According to the doorpanel
configuration, see page 57). In such a case, check door opener condition.
O
The door opener remains enabled.
w
If you are using an alternative current door opener, check its connection by means of the diagram
