2) Setpoint Limit: Specifies the value that the setpoint parameter must exceed for Over
Setpoint or go below for Under Setpoint for the setpoint to become
active. The Setpoint Return Limit is 0.95xSetpoint Limit for Over
Setpoint and 1.05xSetpoint Limit for Under Setpoint.
3) Setpoint Delay: Specifies the minimum duration in seconds that the setpoint condition
must be met before the setpoint becomes active. If the setpoint is
already active, it specifies the minimum duration in seconds that the
Setpoint Return condition must be met before the setpoint becomes
inactive. An event will be generated and stored in the SOE Log for any
setpoint status changes. The range of the Setpoint Delay is between
0 and 9,999 (seconds).
4) Setpoint Trigger: Specifies what action the setpoint will take when it becomes active.
These actions include No Trigger or Trigger DOx.

4.3.2 Digital Input Setpoints
The Digital Input Setpoints can be used to monitor external status and provide alarming and control
capability in response to the external status becoming active. The Digital Input Setpoints can be
programmed from the front panel or via communications. To enable Digital Input Setpoints through
the front panel, enter Setup Configuration mode, scroll to the DI1_PRO and DI2_PRO setup
parameters and choose OFF, DO1 or DO2 from the selection list. The following table illustrates the
operational behavior of the Digital Input Setpoints.
