Suction Pressure Pull Down - This option provides for
a slow lowering of the Suction Pressure when in Suc-
tion Pressure Capacity Control. Slowly “walking” the
pressure down prevents rapid drops in system pres-
sure that causes violent boiling of refrigerant in the
system.
[Enable] - This key is provided if the control is
disabled.
[Disable] - This key is provided if the control is
enabled.
Hot Gas Bypass/SV Setpoint - This option is available
if it applies to the compressor model (Reference “Com-
pressor Model Differences”). This feature is provided to
turn on up to three digital outputs based on an entered
Slide Valve position setpoint. For further setup see the
“Slide Valve Setpoints” screen. A toggle key is provided
that changes between the following selections:
[Hot Gas Enable] - This key is provided if the con-
trol is disabled.
[Hot Gas Disable] - This key is provided if the
control is enabled.
Auxiliaries 3-8 - This provides for selecting additional
(more than 2) auxiliary digital input modules to be used

Auxiliary Analog Temperature and Pressures - This
provides for using one or up to ten analog input auxil-
iaries to monitor either temperature or pressure read-
ings. For further setup see the “Auxiliary Analog Tem-
peratures & Pressures” screen and the “Calibrate Aux-
iliary Analog” screen. A toggle key is provided that
changes between the following selections:
[Analog Auxiliaries Enable] - This key is provided

pressor Model Differences”). This provides for using
the Remote Slide Valve Position analog channel 13.
The remote (4-20 ma) input signal to this channel can
be used to control the Slide Valve. For further setup see
the “Calibrate Slide Valve Position” screen and the [Re-
mote Slide Valve] command key from the Slide Valve
mode screen command keys on the “Operating Status”
screen. A toggle key is provided that changes between
