Test the cable
The cable should be tested for proper function after all the loop units
are connected and before the cable is connected to the central unit. The
cable can only be tested if all short circuit isolators are bypassed.
Note!
It is not allowed to use an insulation tester with a voltage
exceeding 30 V.
Test 1: Test for cable break
Measure the resistance between the + poles and - poles
respectively. Connect an ohm meter between the + poles.
Measure and repeat the procedure for the - poles.
The measured value should be less then 130
Ω for a cable with
a maximum length of 2 km.
Proceed as follows to locate the cable break on addressable
loops:
1.
List the loop units for the actual loop under:
Menu/ 6 Service menu/ 5 Loops
2. Press “2” to list all loop units located on this loop.
3. Each loop unit will report on which side (A or B) it
answers:
(A/B)= answer on both sides
(A/-)= answer only on A side
(-/B)= answer only on B side.
4. The cable break is located between the “last” unit on
the A side and the “first” unit on the B side.
