indicate that the test mode is activated.By default, the test mode can only be changed from
the LHMI. Activation by remote client is possible, see the technical manual.
The Normal LED also flashes if the protection relay detects a diagnostic
failure. Check the test mode setting and the protection relay's IRF alarm
contact status to find the reason for the failure.
