Correction procedures

9.3.1

Changing and setting the password

The password can only be set with PCM600.
9.3.2

Identifying IED application problems

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

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 voltages.
• Check that the phase information and phase shift between phases is correct.
• Correct the wiring if needed.
•
•
• Check the actual state of the connected binary inputs.
