Set Up Delay Time - Emerson Autochangeover Controllers AC8 User Manual

7.5.11 Set Up Delay Time

Each sensor may be set up with a specified time delay between the
triggering of a high or low setpoint—a monitored sensor crosses the
high or low setpoint threshold—and any response by the AC8. This fea-
ture can prevent transient conditions from prompting unnecessary
responses.
This delay is the amount of time that must elapse before the AC8
acknowledges the change in the monitored sensor and takes any fur-
ther action, such as dialing configured pagers. The default time delay
is 1 second (displayed as 00 MIN : 01 SEC).
The time delay applies to the triggering of a high or low setpoint and
also after the monitored sensor returns to its normal state. When the
monitored device returns to its normal state, the specified time delay
must elapse before the AC8 acknowledges the return-to-normal condi-
tion.
• From the Setup Sensor Menu, choose Sensor Delay, as shown at
right, and press Enter .
• To change the time delay in minutes and seconds (in the range of
00:00 to 99:59):
• For minutes (MIN), press and hold one of the arrow keys
• Press Enter
• For seconds (SEC), press and hold one of the arrow keys
to advance to seconds (SEC).
