PI CONFIGURATION
[Action] - One of the following actions will be
shown here:
• Forward - The output will increase at
values greater than the Control Set-
point.
• Reverse - The output will increase at
values less than the Control Setpoint.
[Setpoint] - Enter the value that you wish to
control to.
[Proportional Band] – This setpoint determines
the size of a region either above or below the
Control Setpoint. Within this region, the Pro-
portional component of the PI Output value is
the number between 0% and 100% that directly
corresponds to the difference between the Con-
trol Input (Actual) and the Control Setpoint (Set-
point). Outside of this region, the Proportional
component is either 100% or 0%. If the PI’s Ac-
tion is Forward, the Proportional Band extends
above the Control Setpoint. If the PI’s Action is
Reverse, the Proportional Band extends below
the Control Setpoint.
[Integration Time] - This setpoint controls the
infl uence that the Integral component exerts on
the PI Output value. The Integral component
works to push the Control Input toward the Con-
trol Setpoint by tracking the difference between
the Control Input and the Control Setpoint over
time.
[High Limit] - The highest value that the
output can be is shown.
[Low Limit] - The lowest value that the
output can be is shown.
[Off Value] - If the PI’s Control is set to
When Running, then the value shown here
sets the value of the PI output when the
compressor is off.
STATUS
Control Value - The Actual value of the input
signal. This is not a setpoint value.
Output Value- The value of the Output signal as
controlled by the PI. This is not a setpoint value.
IO SETUP
[I/O Board] - One of the following Analog Boards
will be shown:
• None
• Analog Board 1
• Analog Board 2
[Output Channel] - The analog board output
channel that will be used is shown here.
