Alarms are set up as part of the instrument configuration procedure (Section 4.13). Up to 16 alarms can be
configured.
An alarm can be assigned to any analog data point (Analog Input, Analog Output, or Calculated Value) and
can be one of these types.
Alarm type
HIGH
LOW
DEV (Deviation)
LDEV
HDEV
HRATE (High Rate)
LRATE (Low Rate)
An alarm programmed with delay will not activate before its delay time. An alarm programmed with
hysteresis will clear after its hysteresis delay.
The alarm will remain active as long as the conditions causing it remain. When the conditions no longer
exist, the alarm will be "cleared" automatically. "Clear" means that the indicators for the particular alarm
on all displays will be removed and the alarm will be removed from the Alarm Summary list.
