The internal FIFO register of all events will appear when the event viewer is
launched.
When the IED is brought into normal service it is recommended to delete all events
resulting from commissioning tests to avoid confusion in future fault analysis. All
events in the IED can be cleared in the local HMI under Main Menu//Clear/Clear
internal event list or Main menu/Clear/Clear process event list. It is not possible to
clear the event lists from PCM600.
When testing binary inputs, the event list (EL) might be used instead. No uploading or
analyzing of registrations is then needed since the event list keeps running,
independent of start of disturbance registration.

Use the technical manual to identify function blocks, logic diagrams, input and output
signals, setting parameters and technical data.
13.3 Differential protection

Prepare the IED for verification of settings outlined in Section
"Preparing the IED to
verify settings".
13.3.1.1 Verifying the settings
SEMOD54284-51 v11
1. Go to Main menu/Test/Function test modes/Differential protection and make
sure that the restricted earth fault protection, low impedance function REFPDIF
(87N) is set to Disabled and that the four step residual overcurrent function
EF4PTOC (51N/67N) under Main menu/Test/Function test modes/Current
protection is set to Disabled, since they are configured to the same current
transformer inputs as the transformer differential protection. Make sure that the
