5.11 Alarm Setpoints
Introduction
 An alarm consists of a relay contact and an operator interface indication. The alarm relay is de-energized
if Alarm 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.
 There are twelve alarm setpoints, two for each alarm.
 The type and state (High or Low) is selected during configuration: see Section 3 - Configuration for
details.
ATTENTION
An active alarm will always provide an indication on the display but may not control the relay;
that is, a higher priority function such as a control loop or timer may have control of the relay.
