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.
There are four alarm setpoints, two for each alarm. The type and state
(High or Low) is selected during configuration.
