Illustration33: Fault areas and causes
The following table explains the possible causes.
Fault area Explanation Possible causes
1
Load circuit interrupted after U
R
pickup point
• Wire break, heating element break.
• Contact to heating element is defective.
Current transformer signal inter-
rupted
• I
R
measurement cable from current transformer inter-
rupted.
2
Primary circuit interrupted
• Wire break, triac in controller defective.
• Primary winding of pulse transformer interrupted.
• Kb contactor open.
