1) If the display is flashing, currently no valid signal is being received.
2) This is the case when the timeout for the switchover to the substitute synchroniza-
tion has been selected larger than the monitoring timeout of the external synchroni-
zation.
The timeout for the switchover to the substitute synchronization can be set via the
following parameter entry:
/Redundancy/Redundancy/timeout (0.09.10)
The timeout of the external synchronization can be set via the following parameter
entry:
/Inputs/Input 1/Monitoring/timeout (0.20.01)
/Inputs/Input 2/Monitoring/timeout (0.21.01)
