ALARM RESET MODE ALARM 1
???1 ???? Automatic
????
In Automatic mode, an energized alarm turns off automatically after the
Temperature/Process value leaves the alarm region. In Latched mode, an
energized alarm requires an F1 key or user input alarm reset to turn off. After an
alarm reset, the alarm remains reset off until the trigger point is crossed again.
ALARM STANDBY ALARM 1
???1 ??? Standby on
??
Standby prevents nuisance (typically low level) alarms after a power up or
setpoint change. After powering up the controller or changing the setpoint, the
process must leave the alarm region (enter normal non-alarm area of operation).
After this has occurred, the standby is disabled and the alarm responds normally
until the next controller power up or setpoint change.
ALARM VALUE ALARM 1
???1
? T16
??? P16
The alarm values are entered as process units or degrees. They can also be
entered in the Display or Hidden Loops. When the alarm is configured as
deviation or band acting, the associated output tracks the Setpoint as it is
changed. The value entered is the offset or difference from the Setpoint.

ALARM HYSTERESIS

The Hysteresis Value is either added to or subtracted from the alarm value,
depending on the alarm action selected. The same value applies to both alarms.
See the Alarm Action Figures for a visual explanation of how alarm actions are
affected by the hysteresis.
