14.2.1.17 Binary output: Bus fail
The output is open if healthy bus voltage is present. It closes with a delay
given by bus protections if bus voltage or frequency gets out of the limits.
For example see Mains fail.
14.2.1.18 Binary output: VectorShiftTrp
The output closes if the Vector shift protection gets active. The output stays
closed for 3s, then opens again.
14.2.1.19 Binary output: Horn
The output closes together with the output Alarm. It opens when the output
Alarm is opened or Horn reset button is pressed or Horn timeout has
elapsed.
14.2.1.20 Binary output: Alarm
The output is closed if there is at least one unconfirmed alarm in the alarm
list.
NOTE:
Some alarm types as e.g. Off load, History record, Low power, Mains
protection do not require confirmation, they disappear from the alarm list
automatically when the alarm condition disappears. That means the Alarm
output is not activated by alarms of these types.
