The ALARM RELAY will respond to both a rising and falling
process. The ALARM RELAY will act as a low alarm (falling
process) and a high alarm (rising process). Both relay bands will
have independently adjustable on and off set-points. If a low
alarm set-point is set at a value 20 for example, the off set-point
must be set higher. The controller will not let the user input a
value below 20. The same rule holds true for the high alarm.
The Alarm Relay can be configured for the following operations
-LOW ON Set-point
-LOW OFF Set-point
-HIGH ON Set-point
-HIGH OFF Set-point
-Failsafe

TO HIGH OFF

If you wish to change the setting, press the
key once which will move the cursor to the first
character of the value to be changed

The LOW OFF set point is the value that
the process must reach in order to de-
energize the alarm relay after it has
dropped below and tripped the LOW ON
set-point. This value must be higher than
the LOW ON Set-point.

The HIGH ON set-point is the high process
value that will cause the relay to energize.
This value can be set anywhere 0-100% of
Full Scale.

The LOW ON set point is the low process
value that will cause the relay to energize.
This value can be set anywhere 0-100%
of Full Scale.
