SETPOINT ACTION
: When not using a setpoint, it should be set to
(no action).
For Counter Assignments:
With Timed Out action, the setpoint output activates when the
count value equals the setpoint value and deactivates after the
Time Out value. This action is not associated with Boundary types.
With boundary action, the setpoint output activates when the count
value is greater than or equal to (for
=
) or less than or equal
to (for
=
) the setpoint value. The setpoint output will
deactivate when the count value is less than (for
=
) or
greater than (for
=
) the setpoint value.
With Latch action, the setpoint output activates when the count
value equals the setpoint value. The output remains active until
reset. This action is not associated with Boundary types.
For Rate Assignments:
With Timed Out action, the setpoint output cycles when the rate
value is greater than or equal to (for
=
) or less than or equal
to (for
=
) the setpoint value. The Setpoint Time Out
(
) and Setpoint On Delay (
) values determine the
cycling times.
With Boundary action, the setpoint output activates when the rate
value is greater than or equal to (for
=
) or less than or equal
to (for
=
) the setpoint value. The setpoint output will
deactivate (Auto reset) as determined by the hysteresis value.
With Latch action, the setpoint output activates when the rate value
is equal to the setpoint value. The setpoint output remains active
until reset. If after reset, the rate value is greater than or equal to
(for
=
) or less than or equal to (for
=
) the setpoint
value, the output will reactivate.
Select the display that the setpoint is to be assigned.
SETPOINT VALUE
Enter the desired setpoint value. Setpoint values can also be entered in the
Quick Programming Mode when the setpoint is configured as
in Module 3.
(See Module 2 for Exchange Parameter Lists explanation.)
SETPOINT TRACKING
If a selection other than NO is chosen, then the value of the setpoint being
programmed (“n”) will track the entered selection’s value. Tracking means that
when the selection’s value is changed, the “n” setpoint value will also change
(or follow) by the same amount.
SETPOINT BOUNDARY TYPE
activates the output when the assigned display value (
) equals or
exceeds the setpoint value.
activates the setpoint when the assigned display
value is less than or equal to the setpoint.
SETPOINT STANDBY OPERATION
Selecting
will disable low acting setpoints at a power up until the display
value crosses into the alarm “off” area. Once in the alarm “off” area, the
setpoint will function according to the configured setpoint parameters.
to
The hysteresis value is added to (for
=
), or subtracted from (for
=
), the setpoint value to determine at what value to deactivate the associated
setpoint output. Hysteresis is only available for setpoints assigned to the Rate
with boundary action.
to
This is the amount of time the Rate display must meet the setpoint
deactivation requirements (below hysteresis for high acting and above
hysteresis for low acting) before the setpoint’s output deactivates.
to
seconds
This is the amount of time the Rate display must meet the setpoint activation
requirements (below setpoint for
=
and above setpoint for
=
) before
the setpoint’s output activates. If the Rate Setpoint Action is Timed Out, this is
the amount of time the output is off during the on / off output cycling.
to
seconds
SETPOINT TIME OUT
If the setpoint action is Timed Out and the setpoint is assigned to Rate, then
this is the amount of time the output is on during the on / off output cycling. If
the setpoint action is Timed Out and the setpoint is assigned to Count, then this
is the amount of time the output will activate once the count value equals the
setpoint value.
This automatically resets the display value of the Setpoint Assignment
(
) counter each time the setpoint value is reached. This reset may be
different than the Counter’s Reset Action (x
) in Module 1 or 5.

SELECTION ACTION
No auto reset.
Reset to zero at the start of output activation.
Reset to count load value at the start of output activation.
Reset to zero at the end of output activation. (
action only).
Reset to count load value at the end of output activation. (
action only).
