gefran GPC - Generic Alarms AL1

3.13. Generic alarms AL1 ... AL8
Alarms can be configured to be triggered if the reference
threshold is exceeded (value read greater than maximum
threshold or less than minimum threshold), or if the thresh-
old value is not reached (value read less than maximum
threshold or greater than minimum threshold) or for other
reasons.
The following diagram shows the parameter processing
sequences for the generation of generic alarms.

The Advanced Power Controller has 8 alarms (AL1...AL8)
per module, described as generic, which can take on vari-
ous functions.
The hysteresis value is used to define a band for the safe
re-entry of the alarm condition and to avoid the continu-
ous generation of alarms if the reference signal fluctuates
around the threshold value.
