Alarm Parameters
900M050U00  Athena Controls, Inc. 9-5
9.2.3 Specifying the Alarm Delay – Optional
Unless the alarm will be used to signal ramp/soak recipe event, you can configure an
alarm delay. If you specify an alarm delay, then when the controller detects an alarm
condition, the alarm will not be activated until the alarm delay time has passed. Use the
alarm delay to reduce nuisance alarms for transient conditions that are corrected without
any operator action.

9.2.4 Inhibiting the Alarm– Optional
Unless the alarm will be used to signal a ramp/soak event, you can configure an inhibit
time for the alarm. If you specify an alarm inhibit time, the controller will not activate the
alarm following power up until the alarm inhibit time has elapsed. This is particularly
useful for preventing activation of low alarms during startup (before the process has had
time to reach operating temperature).
