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 at the beginning of this

section for a visual explanation of how alarm actions are affected by the

hysteresis.

Select the Alarm action in the event of a detected input failure (open

TC/RTD or shorted RTD).

ALARM 3 VALUE

The alarm values are entered as process units or degrees. They may

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.
