• Check the current or voltage measurements and their phase information from
Main menu/Measurements.
• 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 from Main menu/
Monitoring/I/O status/Binary input values.
• Test and change the relay state manually in Main menu/Tests/Binary outputs.

Sample data interruptions

Occasionally protection relays can receive corrupted or faulty measurement data
during runtime. In these cases the operation system halts the corresponding
application execution until correct data is received. In case of permanent faults, the
measurement chain should be checked to remove the origin of the faulty measurement
data.
In case of persistent faults originating from protection relay's internal
faults, contact ABB for repair or replacement actions.
