Correction procedures
9.3.1
Changing and setting the password
GUID-D3FA85BA-1E36-4F8B-BD71-85C7AC46A0B4 v1
The password can only be set with PCM600.
For more information, see PCM600 documentation.
9.3.2
Identifying IED application problems
GUID-D8E1AECF-1FD8-4996-A447-948B52EAD0C2 v5
Navigate to the appropriate menu in the LHMI to identify possible problems.
•
Check that the function is on.
•
Check that the correct setting group (1 to 4) is activated.
•
Check the blocking.
•
Check the mode.
•
Check the measurement value.
•
Check the connection to trip and disturbance recorder functions.
•
Check the channel settings.
9.3.2.1
Inspecting the wiring
GUID-665B75A6-A074-4A03-ADF1-3D0FAD198E61 v5
The physical inspection of wiring connections often reveals the wrong connection for phase
currents or voltages. However, even though the phase current or voltage connections to IED
terminals might be correct, wrong polarity of one or more measurement transformers can
cause problems.
•
Check the current or voltage measurements and their phase information from Main
menu/Measurements/Analog primary values or Analog secondary values.
•
Check that the phase information and phase shift between phases is correct.
•
Correct the wiring if needed.
•
Change the parameter
Negation in Configuration/Analog modules/
3PhaseAnalogGroup/SMAI_20_n:1 (n= the number of the SMAI used).
Changing the
Negation parameter is not recommended without
special skills.
•
In PCM600, change the parameter
CTStarPointn (n= the number on the current
input) under the parameter settings for each current input.
•
Check the actual state of the connected binary inputs.
