Cable break
No answer from any section unit
−
The cable is broken before the first section unit on a single ended loop.
−
The cable is broken before the first section unit at least once and it is also broken
after the last section unit, if the loop is a double ended loop.
Section units are answering
Look for the last section unit answering on each side of the loop. The cable
break is situated after or between these units.
Earth fault
•
Check the earth fault circuit, change it if it is faulty.
•
If the circuit is working properly, check the loops one by one.
•
Disconnect the loops one by one, see Disconnection, Electric isolation of a loop.
Short circuit
No answer from any section unit
Search for the short circuit between the central unit and the short circuit
isolator.
Section units are answering
Search for the short circuit between the short circuits reporting the faults.
Proceed as follows when you want to locate an earth fault. Divide the cable in two
halves, locate the earth fault on one of the halves. Thereafter divide this part of the
cable into two halves. Continue to divide the cable into halves until you have found
the earth fault. If you are using a multimeter use the diode tester range.
