Alarm change-over
So that there is a change-over when alarms occur, alarms can be defined as
valid in menus Z3a, Z3b, Z3c and Z3d by adjusting the parameter to “1”. If this
type of alarm (which is defined as valid) occurs, the defective unit is switched
off and the standby unit with the next highest bus address is switched on. If
another unit with a valid alarm in the zone fails, a further standby unit is switched
on if there is one available.
Some alarms lead to the defective unit being switched off or to certain functions
being deactivated even if the alarm has not been defined as valid (for details,
see chapter “11.4 Alarm texts” on page 72).
The “Unit not reachable” alarm cannot be left out of the configuration and so
always remains valid. This alarm also occurs if the unit is de-energized.
