4.10 Alarms

Introduction
An alarm consists of a relay contact and an operator interface indication. The
alarm relay is de-energized if setpoint 1 or setpoint 2 is exceeded.
The alarm relay is energized when the monitored value goes into the allowed
region by more than the hysteresis.
The relay contacts can be wired for normally open (NO) energized or normally
closed (NC) de-energized using internal jumper placement. See Table 2-3 in the
Section 2 – Installation for alarm relay contact information.
There are four alarm setpoints, two for each alarm. The alarm type and state
(High or Low) is selected during configuration. There are several alarm types that
can be selected for each alarm setpoint.
