Fault Finding
Fault Diagnosis
This section is designed to simplify the Task of Fault Finding.
When a message is displayed, the description of the fault is shown and the Problem No. is shown; this in turn then relates to the
relevant page showing the Problem No.
Procedure
Depending on the result of the inspection or measurement inside the box, continue on to either the YES or NO branch and onto
the next box. Inside each box, the inspection or measurement method or values are written. The necessary preparatory work,
operations and values are listed. Make sure the preparatory work is carried out, that is checking the procedures and equipment,
as mistakes in judgements and procedures can seriously damage the equipment.
Note: When removing or checking a piece of electrical equipment turn the key switch OFF.
