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.
Problem Cause Remedy
You hear a negative tone when

• 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 internal
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)
