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.

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.

ALARM RELAY

RELAY A

RELAY B

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 on set-point is set at a value 800uS for example, the off
set-point must be set higher. The controller will not let the user
input a value below the low alarm on. 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
