17.12.4 Consequences of the alarm

When a unit detects a disconnection on the local LAN network, the following occurs:
•
signal on the main mask;
•
forced unit activation in case it is in stand-by;
•
average regulation inhibited, in case it has been previously enabled;
•
Time count interruption for reserve unit rotation.
•
election of a new Priority if the network is divided into several sections.
Moreover, the Priority unit activates a backup unit.
