The installation was made with a
different cable from the one
recommended, with a higher
resistance - >8 W /100m.
5.
The system works OK,
but the voltages measured
to the terminal connectors
(VTM/VTE/ATM) are lower
than 11 Vd.c.
+14 V – GND < 11 V
+Uv – GND < 11 V
(ch. 5.6)

PROG
Only 1 wire connected on +14V
and GND terminals, instead of 2
wires, as shown in the connection
diagram.
The cable length in the system
is higher than 150 m.
We recommend the installation of
a video amplifier (DVA) before or
after SCU. An additional cable of
2
3 x 0,75 mm is required.
6.
The call from the
outdoor panel (VPM/APM)
doesn`t function.
U = 0V or 5V
CD
(ch. 5.6.)
The CD connection could be:
- incorrectly connected or in short
circuit with +14V, +Uv, GND or GNV
- interrupted or not connected to VPM/APM,
VCB/ACB, SCU or VTM/VTE/ATM.
Check CD everywhere in the
system and correct any errors.
The 2nd wire must be connected
to +14V or GND, as shown in
the connection diagram.

VPM/APM is not programmed with
address 1.
Program VPM/APM with address 1, see
the procedure (ch. 6.4.1.). If additional
are installed, they must be programmed
with different address – 2, 3 or 4.
4.
The system doesn`t work.

Short circuit between +14V and

Check the connections between +14V
and GND and/or GNV and +Uv.
Correct any errors.
7.
The terminal
(VTM/VTE/ATM)
doesn`t ring when
called from the
outdoor panel
(VPM/APM).

The CD connection may be interrupted
between SCU, VCB/ACB and
VTM/VTE/ATM.
The terminal VTM/VTE/ATM doesn`t
BEEP
signal with [ ] when the keyboard is
touched.
Program VTM/VTE/ATM with the correct
address, see the procedure (ch. 6.5.1.).
Check CD connection of SCU, VCB/ACB
and VTM/VTE/ATM and the continuity of
the wire. Correct any errors.
VTM/VTE/ATM is not programmed with
the correct address.
Check +14, GND connections of SCU,
VCB/ACB and VTM/VTE/ATM and the
continuity of the wire. Correct any
errors.
11.
The COLOR video
image of the terminal
(VTM/VTE) is blurred
all the time.
High attenuation on the cable
between VPM and VTM/VTE:
- Cable length higher than 150 m
- The cable used is different from
the one recommended (not
twisted and/ or with higher
resistance).
Remove VTM/VTE from the wall,
but keep it connected to
the system. With a PH 0
screwdriver trimmer adjusts the
impedance trimmer (2) from the back
until you get a better image.
9.
The video display of the
terminal (VTM/VTE) is Black
(off) during call and talk.

Short circuit between +Uv and

Check the connections +Uv and
GNV/ GND and correct any errors.
10.
The video display of the
terminal (VTM/VTE) is Blue
during call and talk.
No video signal.
The Vin/ Vout or GNV connection is
interrupted in one connector (VPM, SCU, VCB
or VTM/VTE. Check and correct any errors.
The connections Vin/ Vout or GNV are
reversed somewhere in the system
or in short circuit.
Check Vin/ Vout and GNV
everywhere in the system and
correct any errors.
The video camera is defect.
VPM must be replaced.
8.
There is a disturbing
noise during talk on the
terminal (VTM/VTE/ATM).
The other features are OK.
The wires remained free, including the
shield wire, will be connected only to
the GND connector of SCU (2 wires in GND).

The cable used has more wires than
UTP cat5e (AWG24), which is
recommended for installation.
The GND connections are not OK
(not tight enough).
Check the GND connections of VPM/APM,
VCB/ACB, SCU and VTM/VTE/ATM. Firmly
tighten the wires in the connector.
