for more information.

SELECT.
28. Use the arrow buttons to toggle the
alarm function between latching (alarm

(allowing for any deadband) AND unit is
manually reset) and non-latching (alarm
returns to normal as soon as input returns
to normal, allowing for any deadband)
function.
29. Press SELECT when the display shows
the desired setting. This returns the unit
to the Alarm Configuration menu at “EXIT
ALRM”.
30. Press SELECT to bring up the menu for
the next installed alarm. If no additional
alarms are installed, or to return to the
Main Menu, press SELECT from “EXIT
ALRM”.
To set the operating parameters for the
next installed alarm, use the arrow buttons
from the “EXIT ALRM” screen to display
the next alarm, “AL2 CONF”, for example,
and press SELECT, and return to step 3.
When all of the alarm parameters for all
of the installed alarms have been set
as desired, press SELECT from “EXIT
ALRM”, and press SELECT again from
