ACCESSING:
DESCRIPTION: This screen will be available if Sequencing
is enabled in Compressor confi guration. The screen shown
represents System 1. There are additionally a System 2
and a System 3 setup screen, which are not discussed fur-
ther here, as all three screens show the same layout, al-
though they may get setup using different capacity modes.
Use these screens to setup all of the necessary operating
parameters for performing compressor sequencing. The
information from these three screens will be shown on the
Sequencing Status screen.
SEQUENCE ORDER
On the blue Sequence Order status bar, is an
Enable / Disable button. Use this button to set
the current condition of System 1 (2 or 3):
• Disabled - The compressors that are
listed on this screen will not run as part
of the sequencing scheme (System 1
will be ignored).
• Enabled - The compressors that are
listed on this screen will run when
called for as part of the sequencing
scheme (System 1 will be included).
The following pop-up menus and setpoint boxes
are shown here:
Setpoint - Use this setpoint box to set the

High Stage System Link - The High Stage
System Link setpoint is provided to tie a
system of Booster compressors to a system
of High Stage compressors.
Current Value - This is the actual value for
the capacity control (as measured from the
Leader compressor). The leader compres-
sor is the unit with the lowest IP Address.
It is to this value that the compressors will
attempt to maintain. This is strictly a dis-
played value, and cannot be changed here.
Minimum Run Time - This is the minimum
amount of time that each compressor with-
in this system will run, when called upon to
do so.
There are eight rows of setpoint boxes shown
at the bottom of this screen. These rows cor-
respond to up to eight different compressors,
which combined will make up this system. The
user may program as few or as many of these
rows as their situation requires:
Sequencing ID - Enter the last octet of the
IP Address here. This will identify each of
the possible eight compressors to the
Leader A row with a 0 (zero) as the
