Introduction
An alarm consists of a relay contact and an operator interface indication.
The alarm is de-energized if Setpoint 1 or Setpoint 2 is exceeded. The
alarm 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) or normally
closed (NC) at the rear terminals. See Section 2 — Installation for details.
There are four alarm setpoints, two for each alarm. The type and state
