ALARM 2 STANDBY
Y
Standby on
NO
Standby off
Standby prevents nuisance (typically low level) alarms after a power
up. After powering up the controller, 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.
ALARM 2 RESET MODE
Auo
Automatic
LA
Latched
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 1 / 2 key or user input alarm reset to
turn off. After an alarm reset, the alarm remains off until the trigger point
is crossed again.
ALARM 2 VALUE
The alarm values are entered as process units or degrees. They can
also be entered in the Parameter 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 3 parameters in this module are programming dependent. They
are available only when Output 2 control action is programmed as alarm.
On OFF
Select the Alarm action in the event of a detected input failure (open
TC/RTD or shorted RTD).
Shaded parameters are programming/model dependent.
