5. TROUBLESHOOTING
In case of problems, always first check with a multimeter whether the following
voltages
are present:
• between b and a: approx. +24VDC;
• between b and P: approx. +24 VDC;
• between M and P: approx. +24VDC;
• between M and V1 or V2: approx. +5VDC.
A list of possible problems with their causes and remedies is given below.

If a call is in progress, the relay switches to open the door.
If no call is in progress, the light relay switches.
The image on the video internal
unit is not clear.
Conductors V1 and V2 have been
reversed.
Reverse conductors V1 and V2.
Cable is unsuitable:
• cable distance is too great;
• cable is eroded;
• cable cross-section too small;
• cable is not a twisted pair cable.
Replace the current cable with a suitable cable.
The gain on the splitters is not set cor-
rectly.
Adjust the gain on the splitters with the potentiometers.
No image on the video inter-
nal unit. The other functions
work OK.
Wiring is not connected correctly:
• M or P missing;
• V1 or V2 not connected.
Check the wiring (see wiring diagram).
Jumpers not configured correctly.
Set the jumpers correctly on the contacts (see chapter Installation)
