Introduction
Procedure for
displaying the alarm
setpoints
4/00
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 at the rear terminals. See Table 2-8 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 Section 3 –
Configuration for details.
Table 5-20 lists the procedure for displaying and changing the alarm
setpoints.
