TROUBLE SHOOTING

Nothing works
Check whether the power supply led is unlit.
a) Check the mains voltage b) Disconnect the +, -
terminals of the power supply and verify that the
voltage at the terminals is 18Vdc. If there is no
voltage detected at these terminals, the power supply
unit may be defective. Otherwise, check if there is
a short circuit in the +, - connections between the
devices of the installation.
It is not possible to make a call from the
entrance panel. There is no voltage in
the entrance panel
(If there is voltage in terminals 1,2 of the entrance
panel (15-18Vdc) see the next point.)
Disconnect cables 1 and 2 of the monitor and
check the voltage in the terminals. If this voltage is
correct, check the cable between the monitor and
the entrance panel. Otherwise, if the voltage is not
correct, the monitor may be defective.
It is not possible to make a call from the
entrance panel
Check the specifications about distances and
cross section cables shown in the first page of this
manual. If no fault is detected, the entrance panel
may be defective.
You cannot hear the entrance panel in
the monitor
Adjust the volume using the monitor's volume control.
If no fault is detected, the monitor or entrance panel
may be defective.

You cannot hear the monitor from the
entrance panel
Adjust the volume using the volume control on the
entrance panel. If no fault is detected, the monitor
or entrance panel may be defective.
The voltage supplied to the door opener
is very low
The entrance panel is designed to send an impulse
signal to the electric lock followed by a maintain
current. It is not possible to measure this pulse with
a tester, so the measurement corresponds to the
maintain current, which could be between 3V and
14V. This allows the activation of electric locks with
coils of 10 to 50 ohms, which corresponds with
most of the electric locks, so it is not anomaly. If the
electrick lock is not working see the next point.
The electric lock is not working
If the electrick lock has polarity, check that the
positive terminal is connected to terminal 5 and
the negative terminal to terminal 6 of the entrance
panel. Verify that the terminal resistance of the door
opener is between 10 and 50 ohms.
Verify that the voltage is present in the electric lock,
if not, disconnect cables 5 and 6 from the entrance
panel and check the voltage in terminals, if there
is no voltage the entrance panel may be defective.
If not, check the cable between the entrance panel
and the electric lock.
