ALARM 1 RESET MODE
ï²ïï´1 ï
ïïµï´ï¯ Automatic
ï ïïµï´ï¯ ïïï´ï£ 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 reset off until the trigger point is crossed again.

ALARM 1 STANDBY
ïï
ï Standby on
ïï 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 1 VALUE
ïï¹ï¹ï¹ to ï¹ï¹ï¹ï¹
The alarm values are entered as process units or degrees. They can be entered
in the Parameter or Hidden Loops, when enabled in 3-LC. 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
at which the alarm condition will occur.
