command keys on the Operating Status screen.
The Remote Slide Valve Position option can be used.
This option which is enabled in Panel Setup is not
available for all compressor models (Reference Com-
pressor Model Differences). This uses a (4-20 ma) in-
put signal to the Remote Slide Valve Position analog
input (Channel #13 on Analog Board #1) to control the
Slide Valve. For further setup see the Calibrate Slide
Valve Position screen and the [Remote Slide Valve]
command key from the Slide Valve Mode screen
command keys on the Operating Status screen.
The Slide Valve Position \ Capacity analog output can
be used to determine the present Slide Valve posi-
tion % or Capacity % dependent on the compressor
model (Reference Compressor Model Differences). A
(4-20 ma) output signal to the Slide Valve Position \
Capacity analog output (Channel #3 on Analog Board
#1) corresponds to the present (%) value displayed on
the Operating Status screen.
ASCII communication to the Com-2 port can be used
(reference 090.040-CS Communications Setup man-
ual). A compressor should be in both Remote Com-
pressor Mode and Remote Slide Valve or Capacity
Mode for Remote Control.
Note 1: If the compressor is in Remote mode and
communication through the communication port has
not occurred for 5 minutes, then the compressor is
placed into Automatic mode and the Slide Valve is
placed into Auto mode.
Note 2: If there is a shutdown in response to a safety
setting, a compressor in Remote mode is placed into
Manual mode requiring operator intervention.
