Alarm Setpoints

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 type and state (High or Low) is
selected during configuration. See Subsection 4.6 – Configuration for details.
