Setting up Control Channels
Closed-loop control channels can be set up in various ways in
the PPC-2000. The following procedure identifies the basic
steps:
1.
See
parameters. On the
Inputs
spreadsheet:
a.
Choose the appropriate
Input Type
for the sensor con-
nected to each analog input you have wired.
b.
Choose
Units
for each analog input.
c.
For any linear voltage, current, or pulse sensors, set
the linear scaling parameters (
Input Signal Lo, Input Sig-
nal Hi, PV Lo,
and
PV Hi
). See
2.
See
for descriptions of the channel
parameters. On the
Channels
spreadsheet:
a.
Choose the input in the
PV Source
field that you want
to monitor or use as feedback for closed-loop control
for each channel.
b.
Choose outputs in the
Heat Output Dest
and/or
Cool Out-
put Dest
fields for each channel that you want to use
for closed-loop control.
c.
Choose a
Heat/Cool Output Type
for each output.
d.
Set the
Heat/Cool Cycle Time
for any outputs with
Heat/
Cool Output Type
set to
Time Prop
.
3.
See
for descriptions of the digital
I/O parameters. On the
Digital I/O
spreadsheet:
a.
Set the
Direction
for each I/O point to be used for con-
trol to
Output
.
4.
On the
Channels
spreadsheet:
a.
Set the
Heat/Cool Prop Band
for any outputs with
Heat/
Cool Output Type
set to
On/Off
to 1.
b.
Set the PID parameters (
Heat/Cool Prop Band, Heat/Cool
Derivative
, and
Heat/Cool Integral
) for each output used
for PID control. The parameters may be determined
by performing an autotune on each channel or by oth-
er means. See
mation on autotuning.
c.
If both heat and cool outputs are used, set the
Spread
.
d.
Set the
Set Point
to the desired value and the
Control
Mode
to
Auto
to begin closed-loop control.
