AIR CARE
SEMINAR TRAINING
Sullair Air Care Seminars are 3-day courses that provide hands-on instruction in the proper operation, mainte-
nance and service of Sullair equipment. Individual seminars on Industrial compressors and compressor electrical
systems are presented at regular intervals throughout the year at a dedicated training facility at Sullair’s corporate
headquarters in Michigan City, Indiana.
Instruction includes discussion of the function and installation of Sullair service parts, troubleshooting of the most
common problems, and actual equipment operation. The seminars are recommended for maintenance and serv-
ice personnel.

SECTION 1.1 SUPERVISOR II PROTOCOL VER 3.0
This document describes features that are more technical in nature than the normal opera-
tion of the machine, in particular sequencing and communication.
The Supervisor II communications link is a RS-485 (two wire) serial line. The following three
parameters must be set correctly to be able to communicate through this link.
COM ID# Unique number for each machine on the link.
BAUDRATE Must be the same for all machines (default is 9600).
SEQUENCE Sequencing mode (see below).
The function of the link is specified by the setting of the Sequence parameter as follows :
DISABLED Responds to status and parameter change messages but will not
respond to messages to start, stop, load or unload.
REMOTE Responds to status and parameter change message but will not
respond to messages to start, stop, load or unload. The remote inputs
and outputs are enabled (start/stop, load/unload, master/local).
SLAVE Will respond to all messages, but will not start or load unless com-
manded to do so by a message. This mode is used to control the
machine from a master computer.
HOURS Sends net status message about once a second, starts, loads and
unloads machines based on sequencing hours.
COM ID# Sends net status message about once a second, starts, loads and
unloads machines based on machine Com ID#.
If the sequence parameter is set to Hours or Com ID# then the following parameters must
be set (see section on Sequencing Methods) :
LAST COM Highest Com ID#
LOWEST Lowest line pressure before starting machine.
RECOVER Recovery time.
ROTATE Machine rotation time.
CAPACITY Capacity of the machine.
SEQ HRS Sequencing hours.
See Sequencing (Section 2) for detailed descriptions of sequencing parameters and operation.
Messages can be sent between Supervisor II controls and to/from a computer. There are two
modes of operation, query and broadcast.
If the sequence parameter is set to DISABLED, REMOTE, or SLAVE then the query mode
is enabled. The Supervisors will only send messages in response to a message from the
host computer. In DISABLED and REMOTE the Supervisor controls the machine locally (ie.
start, stop load, and unload) and will ignore any messages to start, stop, load or unload.
Only status and parameter change messages will be acted on. In SLAVE mode the
Section 1
SUPERVISOR PROTOCOL
2
Supervisor will not start, stop, load or unload unless a message commands the action.
If the sequence parameter is set to HOURS or COM ID# then the broadcast mode is
enabled. In this mode the machines send the net status message periodically.
Approximately once a second, all machines that are on line will send a net status message.
In this manner, each machine knows the status of every other machine. Sequencing deci-
sions are made individually by each machine based on the status of all on line machines in
the system. Collisions on the serial channel
are avoided by a time slice scheme (See section on Time Slice).
BROADCAST MODE OFFERS SEVERAL ADVANTAGES:
1. Because there is no master, the number of messages are cut in half (decreasing
response time). In master/slave mode the master must send a message to request sta-
tus and the machine must send a message back. In broadcast mode, each machine
sends it’s status approximatley once a second.
2. When a machine goes off line or on line there is no need to poll for a new master.
3. Individual machines may be taken off line or put on line with no effect on communications.
This is handy for maintenance or when a machine is to be controlled manually.When the
machine is stopped it still sends net status messages so other machines or a monitor can
display it’s status. When the machine is DISABLED it will not send net status messages
but will respond to status and parameter change messages.
4. Because decisions are made locally, the response of the system is very good, less than
one second for trimming, loading and unloading. One second plus starting time for a
machine to start.
5. There are no extra communications for monitoring. Since each machine sends it’s status
every second, the monitor does not need to send messages. However, the monitor may
send messages to get other status, change parameters or issue run commands (for
example a machine may be stopped from the monitor).
6. The monitor does not need to be continuously connected. A monitor may be connected
or disconnected at any time.
MESSAGE FORMAT
All messages will have the following format.
@ Start of text (2)
## Two character com number
m One character message type
d Zero to several data characters (values separated by comma’s)
xx Two character check sum
CR Carriage return (13)
LF Line feed (10)
For the following examples the STX, CR and LF will not be shown.
Message transmission format is 8-bit, 1-stop bit, no parity.

MESSAGE TYPES
The following messages sent by the sequencing master to slaves:
MESSAGE TYPE FORMAT EXAMPLE
Q - Quick status ##Qxx 01Q4E
S - Stop ##Sxx 01S4C
U - Unload ##Uxx 01U4A
L - Load (Modulate) ##Lxx 01L53
F - Full load ##Fxx 01F59
T - Trim (Modulate) ##Txx 01T4B
E - Emergency Stop ##Exx 01E5A
If a machine is stopped U, L, F or T will start the machine.
The slave response to these messages is:
MESSAGE TYPE FORMAT EXAMPLE
q - Quick status ##q1,2,h,r,mxx 01q0,115,2000,M,C65
1 is Capacity, 2 is P2, h is Run Hours, r is Run Status and m is Mode
RUN STATUS (r)
E - E-Stop
M - Manual Stop m - Manual stop & Common Fault
R - Remote Stop r - Remote stop & Common Fault
B - Standby b - Standby & Common Fault
S - Starting s - Starting & Common Fault
U - Unloaded u - Unloaded & Common Fault
L - Loaded l - Loaded & Common Fault
T - Trim t - Trim & Common Fault
F - Full load f - Full load & Common Fault
MODE (m)
A - Auto run mode, remote start/stop enabled.
a - Auto run mode, remote start/stop disabled.
C - Cont run mode, remote start/stop enabled.
c - Cont run mode, remote start/stop disabled.
The following messages sent by machines when the system is in stand alone sequencing :
MESSAGE TYPE FORMAT EXAMPLE
N - Net status ##N1,2,h,r,mxx 01N0,115,2000,M,C88
M - Monitor Enable ##Mxx 01M52
1 is Capacity, 2 is P2, h is Run Hours, r is Run Status and m is Mode.
