2 Fault analysis and elimination
The following procedure is recommended for isolating the cause of the fault and enabling
effective repair of the KRC:
2.1 Fault analysis
Is the fault reproducible?
-- Permanent fault
-- Sporadic fault
Did the fault occur after installation or conversion?
-- Transportation damage
-- Commissioning faults
Did the fault occur during operation?
-- Operator influence, incorrect operation
-- Program modifications
-- Software configuration modifications
W as the fault caused by external factors?
-- Electrical factors such as undervoltage/overvoltage, static electricity , interference fields
-- Mechanical factors such as impact, vibration
-- Environmental factors such as heat, cold, humidity
What is the fault profile?
-- Observe the status of operator control and display elements on the KR C
(switch positions, lamps, LEDs)
-- Interpret error messages in the message window of the KCP
(for more detailed information see Section 3.2 and the following sections)
-- Collate the statuses and error messages of higher--level controllers
(process control systems, automation components)
-- Read logbook entries
2.2 Isolation of faults using checklists
The cause of the fault can be isolated by comparing the fault profile with a list of typical fault
profiles (see Section 3.1.5).
2.3 Isolation of faults by exchanging components
In the case of a potentially defective overall system, functioning modules are introduced
into the system one after the other and changes in the behavior of the system are observed.
In the case of a potentially defective component, this is introduced into a functioning
system and changes in the behavior of the system are observed.
