Acknowledging collective/dosing alarms
The collective alarm combines all alarms in the alarm list. It simplifies signaling
of one or several active alarms with external indicating devices or to control
rooms. The digital signal for the collective alarm is available in the binary selec-
tor in 2 versions:
•
Collective alarm: Is triggered by the occurrence of any alarm and disap-
pears only after all alarms in the alarm list have been cleared.
• Collective alarm ack.: Is triggered by the occurrence of any alarm and dis-
appears when the alarm is acknowledged.
Selection of a collective alarm when configuring device functions and
digital outputs:
Binary selection > Alarm and Internal Signals >
Collective Alarm/Collective Alarm Ack.
Dosing alarms are triggered by the controllers if the absolute value of the con-
trol deviation is larger than the "alarm tolerance". An "alarm delay" can be set for
each dosing alarm. Dosing alarms and acknowledgment of them must be acti-
vated in the controller configuration. The "alarm tolerance" and "alarm delay"
settings are made in the controller parameters.
