ARW Low Limit Ċ The Anti-Reset Windup (ARW) low limit sets the low
limit for the anti-reset windup function. The valid range is -13.97 to
113.97 percent, and is tunable using DDP #20, ARW LOLM. Refer to
ARW HIGH LIMIT for a complete description.

Description
1 Manual Station For manual (operator) adjustment of the controller output. Used with
Manual Loader PCA only.
2 Auto/Manual Station In Auto, PCA determines the controller final output value. In manual,
controller output is manually adjusted. Used with the following PCAs:
Bias and Gain Notch Gain PI/PID
Signal Selector Adaptive Gain PI/PID
P/PD with Bias Control Sequence
PI/PID/I Control Sequence with Bias
Error-Squared PI/PID
3 Auto/Manual/RSP Station Auto and manual modes are the same as Auto/Manual Station.
Remote Set Point is an automatic mode in which the set point is
received from a different source (such as an analog input) and is not
operator-adjustable. Used with the following PCAs:
P/PD with Bias Notch Gain PI/PID
PI/PID/I Adaptive Gain PI/PID
Error-Squared PI/PID Control Sequence
Control Sequence with Bias
4 Auto/Manual/SUP Station Auto and manual modes are the same as in Auto/Manual Station.
Supervisory is an automatic mode in which the set point is received
from a host computer and is not operator-adjustable. Used with the
following PCAs:
P/PD with Bias Notch Gain PI/PID
PI/PID/I Adaptive Gain PI/PID
Error-Squared PI/PID Control Sequence
Control Sequence with Bias
5 Auto/Manual/DDC Station Auto and manual modes are the same as in Auto/Manual Station. In
Direct Digital Control, a host computer sends a valve output value to
the controller. Used with the following PCAs:
P/PD with Bias Notch Gain PI/PID
PI/PID/I Adaptive Gain PI/PID
Error-Squared PI/PID Control Sequence
Control Sequence with Bias
6 Manual/DDC Station Manual mode is the same as Manual Station. In DDC, a host computer
sends an output value to the controller. Used with Manual Loader PCA
only.
7 Auto/Manual/DDC/SUP
Station
Same as Auto/Manual/DDC Station, except that a supervisory mode is
also available. Supervisory is an automatic mode in which the set
point is received from a host computer and is not
operator-adjustable. Used with the following PCAs:
P/PD with Bias Notch Gain PI/PID
PI/PID/I Adaptive Gain PI/PID
Error-Squared PI/PID Control Sequence
Control Sequence with Bias
