Analog
refers to a remote analog set-point applied to Pin 4 of the Mini-DIN connector as described
in the installation section of this manual. To determine what type of analog set-point your controller
was ordered with, refer to the Calibration Data Sheet that was included with your controller. 0-5 Vdc is
standard unless ordered otherwise. Note that if nothing is connected to Pin 4, and the controller is set
for analog control, the set-point will float at some positive value.
Serial
refers to a remote digital RS-232 set-point applied via a serial connection to a computer or PLC
as described in the Installation and RS-232 sections of this manual.
Local
refers to a set-point applied directly at the controller. For more information on changing the set
-point locally refer to the heading “Select” below. Local input must be selected prior to attempting to
change the set-point locally.
Loop
– The PC Series is defaulted to pressure.
Select – To avoid accidental changing of the PID loop parameters or the set-point, the Control Setup
mode defaults with the selector on a null position. To change the set-point or the P and D PID loop
parameters, push the button in the upper left corner just above the dynamic label “Select” until the
selection arrow is pointing to the parameter you wish to change. When the parameter you wish to
change is selected, it may be adjusted up or down with the buttons under the display below the dynamic
labels “UP” and “DOWN”. Press the buttons repeatedly to make slow adjustments or hold them down
to make fast adjustments.
P
refers to the Proportional term of the PID loop. Before changing this parameter, it is good practice to
write down the initial value so that it can be returned to the factory settings if necessary.
D
refers to the Differential term of the PID loop. Before changing this parameter, it is good practice to
write down the initial value so that it can be returned to the factory settings if necessary.
Set
refers to the Set-point. This parameter may only be changed if “Local” is selected as the Input. See
above for information on selecting the input. Using the UP and DOWN buttons, the set-point may be
adjusted between zero and the full-scale range of the controller.
