SEQUENCING WITH MULTIPLE SUPERVISOR CONTROLS

2.1 NORMAL OPERATION
Supervisor and Supervisor II Deluxe controllers all feature internal sequencing functions. To
enable any Supervisor in the system, press the Auto key
and Remote key
on the key-
pad. Enable the Supervisor II Deluxe by simply pressing the Auto
button. Any unit can
be stopped by pressing the STOP key
, and remaining members will continue to operate
as needed.
The Supervisor Controller has a Remote keypad
on the display module that is used to
enable and disable the controller from any sequencing mode that is currently programmed.
When the Remote key
is first pressed after sequencing has been programmed, it will
enable that mode and light the REMOTE LED on the Display Module. Pressing that keypad
again will turn off the LED and disable the sequencing mode. The compressor will then oper-
ate as though it is not in any sequencing mode. The process will be reversed when the key-
pad is pressed again.
2.2 COMPRESSOR SYSTEM
Internal controller sequencing is designed to operate a group (2-16) of compressors feed-
ing a common header. As air demands change, the compressors will be controlled to deliv-
er the required compressed air in an efficient manner. If a group of similar compressors is
used, the controllers can be set up to automatically rotate operation to equalize run time.
Or, the controllers can be set up for a desired order of compressor operation. The three
modes of sequencing are:
SEQUENCE HOURS -
In this mode, machines are started and loaded depending on the
SEQUENCE HOURS parameter. The sequence hours parameter is similar to run hours
except that it can be changed. Digital inputs for Remote control are disabled. ROTATE hours
are disabled.
COM NUM -
In this mode, machines are started and loaded depending on the COMMUNI-
CATION NUMBER parameter. Operation is exactly the same as the SEQUENCE HOURS
method (see above) except the communications number is used to determine machine
sequence instead of sequence hours. Digital inputs for Remote control are disabled.
SEQUENCE HOURS with ROTATE Hours Enabled -
A special version of SEQUENCE
hours for balancing run hours for use in only two-machine applications that has a demand
for only one machine. DO NOT use with more than two machines (See ROTATE hours
parameter setting for more information). Digital inputs for remote control are disabled.
It is best if the P2 (line pressure) transducers of all machines are connected to a common
header, down stream of individual dryers, etc. Note that the dP1 (separator maintenance
DO NOT enable this mode when the above situation is NOT true, because unexpected starts
and stops may occur when manually starting or stopping a machine in the sequence for main-
tenance.
