5.2.7 Alarm Reset
This command allows an overriding reset of the alarm. Without this command, the alarm will be
switched off, as prescribed by the TM command, using a timer or an external trigger signal.
5.2.8 The Whole Alarm Story in State Diagrams
The following set of commands defines the alarm behaviour: TM, TZ, TT, TB, AF, AR, EF, RC
and SC to get the sector result which will be tested for the alarm limits.
The follow state diagram shall show the function of each.
Figure 3: Alarm State Machine
One should keep attention to the RC command! It overwrites the output of the alarm state machine!
(But, to reduce problems it gets not saved, it will always be: RC==A after reset.)
The alarm is switched off if TB = TT (both alarms) or TB = RB (low limit alarm) or TT = RT (upper limit
alarm).
