SAFETY
NOTE
DO NOT modify the compressor except with written
factory approval.
Each day, walk around the air compressor and
inspect for leaks, loose or missing parts, damaged
parts or parts out of adjustment. Perform all
recommended daily maintenance.
OPERATOR IS REQUIRED TO READ
ENTIRE INSTRUCTION MANUAL.
1.1
Inspect for torn, frayed, blistered or otherwise
deteriorated and degraded hoses. Replace as
required.
GENERAL
Sullair Corporation designs and manufactures all of
its products so they can be operated safely.
However, the responsibility for safe operation rests
with those who use and maintain these products. The
following safety precautions are offered as a guide
which, if conscientiously followed, will minimize the
possibility of accidents throughout the useful life of
this equipment. Read the CIMA Safety Manual
prior to compressor operation and towing, if
applicable in your area.
The air compressor should be operated only by those
who have been trained and delegated to do so, and
who have read and understood this Operator’s
Manual. Failure to follow the instructions, procedures
and safety precautions in this manual can result in
accidents and injuries.
NEVER start the air compressor unless it is safe to
do so. DO NOT attempt to operate the air
compressor with a known unsafe condition. Tag the
air compressor and render it inoperative by
disconnecting the battery so others who may not
know of the unsafe condition will not attempt to
operate it until the condition is corrected.
CAUTION
Estimated hose life based on a 5-day 8-hour
work week is 3 years. These conditions
exist on an 8-hour shift only. Any other
operation of the equipment other than 8hour shifts would shorten the hose life
based on hours of operation.
1.2
TOWING (I)
PREPARING TO TOW
WARNING
Do NOT tow the compressor should its
weight exceed the rated limit of the tow
vehicle, as the vehicle may not brake safely
with excess weight. See rated limit in tow
vehicle Operator's Manual, and review its
instructions and other requirements for
safe towing.
Use and operate the air compressor only in full
compliance with all pertinent OSHA requirements
and/or all pertinent Federal, State and Local codes or
requirements.
(I) WHILE NOT TOWED IN THE USUAL SENSE OF THE WORD, MANY OF THESE INSTRUCTIONS ARE DIRECTLY APPLICABLE TO SKID-MOUNTED
PORTABLE AIR COMPRESSORS AS WELL.

Make sure that the coupling device and adjacent
structures on the towing vehicle (and also, if utilized, chain adjustment, brake and/or electrical
interconnections) DO NOT interfere with or
restrict motion of any part of the compressor,
including its coupling device, with respect to the
towing vehicle when maneuvering over any
anticipated terrain.
G. If provided, make sure chain length, brake and
electrical interconnections provide sufficient
slack to prevent strain when cornering and
maneuvering, yet are supported so they cannot
drag or rub on road, terrain or towing vehicle surfaces which might cause wear that could render
them inoperative.
WARNING
This equipment may be tongue heavy. DO
NOT attempt to raise or lower the drawbar
by hand if the weight is more than you can
safely handle.

doing so, or else secure the access door in the
open position to avoid the possibility of others
closing and possibly latching the door with personnel inside.
1.11 JUMP STARTING
A. Observe all safety precautions mentioned elsewhere in this manual.
B. Batteries may contain hydrogen gas which is
flammable and explosive. Keep flames, sparks
and other sources of ignition away.
C. Batteries contain acid which is corrosive and poisonous. DO NOT allow battery acid to contact
eyes, skin, fabrics or painted surfaces as serious
personal injury or property damage could result.
Flush any contacted areas thoroughly with water
immediately. Always wear an acid-resistant
apron and face shield when attempting to jump
start the compressor.
D. Remove all vent caps (if so equipped) from the
battery or batteries in the compressor. DO NOT
permit dirt or foreign matter to enter the open
cells.
E. Check fluid level. If low, bring fluid to proper level
before attempting to jump start (not applicable to
maintenance-free batteries).
F.
DO NOT attempt to jump start if fluid is frozen or
slushy. Bring batteries up to at least 60 °F (16
°C) before attempting to jump start or it may
explode.
G. Cover open cells of all compressor batteries with
clean dampened cloths before attempting to
jump start.
H. Attempt to jump start only with a vehicle having a
negative ground electrical system with the same
voltage, and is also equipped with a battery or
batteries of comparable size or larger than supplied in the compressor. DO NOT attempt to
jump start using motor generator sets, welders or
other sources of DC power as serious damage
may result.
I.
Bring the starting vehicle alongside the compressor, but DO NOT permit metal to metal contact
between the compressor and the starting vehicle.
J. Set the parking brakes of both the compressor (if
provided) and the starting vehicle or otherwise
block both sides of all wheels.
K. Place the starting vehicle in neutral or park, turn
off all non-essential accessory electrical loads
and start its engine.
L. Use only jumper cables that are clean, in good
condition and are heavy enough to handle the
starting current.
M. Avoid accidental contact between jumper cable
terminal clips or clamps and any metallic portion
of either the compressor or the starting vehicle to
minimize the possibility of uncontrolled arcing
which might serve as a source of ignition.
N. Positive battery terminals are usually identified
by a plus (+) sign on the terminal and the letters
POS adjacent to the terminal. Negative battery
terminals are usually identified by the letters
NEG adjacent to the terminal or a negative (-)
sign.
O. Connect one end of a jumper cable to the positive (POS) (+) battery terminal in the starting
vehicle. When jump starting 24V compressors
and if the starting vehicle is provided with two (2)
12V batteries connected in series, connect the
jumper cable to the positive (POS) (+) terminal of
the ungrounded battery.
P. Connect the other end of the same jumper cable
to the positive (POS) (+) terminal of the starter
motor battery in the compressor, or when jump
starting 24V compressor, to the positive (POS)
(+) terminal of the ungrounded battery in the
compressor.
Q. Connect one end of the other jumper cable to the
grounded negative (NEG) (-) terminal of the battery in the starting vehicle. When jump starting
24V compressors and if the starting vehicle is
provided with two (2) 12V batteries connected in
series, connect the jumper cable to the negative
(NEG) (-) terminal of the grounded battery.
R. Check your connections. DO NOT attempt to
start a 24V compressor with one 12V battery in
the starting vehicle. DO NOT apply 24V to one
12V battery in the compressor.

procedure. Avoid prolonged cranking.
U. Allow the compressor to warm up. When the
compressor is warm and operating smoothly at
11
SECTION 1
normal idle RPM, disconnect the jumper cable
from the engine block in the compressor, then
disconnect the other end of this same cable from
the grounded negative (NEG) (-) terminal of the
battery in the starting vehicle. Then disconnect
the other jumper cable from the positive (POS)
(+) terminal of the battery in the compressor, or if
provided with two (2) 12V batteries connected in
series, from the ungrounded battery in the compressor, and finally, disconnect the other end of
this same jumper cable from the positive (POS)
(+) terminal of the battery in the starting vehicle
or from the positive (POS) (+) terminal of the
ungrounded battery in the starting vehicle, if it is
provided with two (2) 12V batteries connected in
series.
V. Remove and carefully dispose of the dampened
cloths, as they may now be contaminated with
acid, then replace all vent caps.

PRESSURE CALIBRATION
AUXILIARY TEMPERATURE CALIBRATION
Over time the P1, P2, and P3 pressure transducer
values might drift resulting in an inaccurate reading
showing on the pressure gauge. Using the Pressure
Calibration function the operator can adjust the
actual zero pressure to 0.00 BAR when no pressure
is present in the compressor. The offset value will be
subtracted from the transducer value to obtain an
adjusted reading used for indication and calculation.
Occasionally, and when the auxiliary temperature
input is first configured, the input may require
calibration to adjust the input to the actual known
temperature.
This is accomplished using the
Auxiliary Temperature Calibration function.
The
auxiliary
temperature
calibration
offset
is
configurable in 0.5°C increments. A total offset of +/10°C is allowable. The offset will be applied to the
RTD input signal and used for indication and
calculation during compressor operation.
To calibrate a pressure transducer:
1. Select the transducer (P1, P2, or P3) to be
calibrated by pressing both the “m” and “t”
buttons at the same time.
2. The following screen sequence will be presented (example below). This example
shows a P1 pressure of .60 BAR on a
machine that is known to actually be at zero
pressure. The current pressure value is displayed in metric units only (1 kPa = 0.01
bar).
3. Calibrate the actual pressure reading back
down to 0.00 by increasing the value of the
correction / offset by pressing the “t” button
until the Actual Pressure reads 0.00. Once
this is done, simply press both the “m” and
“t” buttons together to store this value in the
system. The offset value will be subtracted
from the transducer value to obtain the
adjusted reading. The calibration offset is
configurable in 1 kPa increments. A total offset of 0-50 kPa (0-7.25 PSI) is allowable.

DESCRIPTION
4.1
INTRODUCTION
This section describes the operation of the Compass
Controller, the function of the controller components,
and the various types of displays that may appear on
the display screen. Descriptive lists of all messages
appearing in the display are also provided.
4.2
OPERATING MODES
SLEEP MODE
Sleep mode occurs when the Compass Controller is
not powered on. All electrical components are
inactive during Sleep mode to prevent battery
drainage (i.e. microprocessor, relays, indication
lamps, etc).
Sleep mode is dependent upon the position of the
Off/On/Start switch and current operating status of
the compressor. If the compressor is in any state
other than running, then placing the Off/On/Start
switch in the OFF position will enter Sleep mode. If
the compressor is running, placing the Off/On/Start
switch in the OFF position will initiate Waiting mode
followed by Sleep mode.
If the compressor has shutdown due to fault
condition, then the fault must be acknowledged by
pressing the reset switch and switching the Off/On/
Start switch to the OFF position.
If the compressor was enabled via Remote Start, a
compressor malfunction will allow entering Waiting
mode only. The malfunction must be acknowledged
by pressing the Reset switch and Off/On/Start switch
must be in the OFF position to enter into Sleep
mode.
START-UP MODE
Start-up mode initializes the system instrumentation
components for operation. Start-up mode is internal
to the Compass Controller and does not permit
engine/compressor activation.
Start-up mode is enabled by one of the following
two methods:
1. Press the Off/On/Start switch to ON.
2. Activating the Remote Start switch (if
enabled).
Placing the Off/On/Start switch to the ON position will
energize the Master Gauge and begin initializing the
system for Waiting mode.
Start-up mode may be exited/cancelled before
reaching Waiting mode. If Start-up is entered by
placing the Off/On/Start switch in the ON position,
placing the switch in the OFF position powers down
the entire system.
If a start-up initialization
parameter is out-of-tolerance, the Compass
Controller will enter a safe-shutdown state and
demand user interaction to completely power down
the unit.
NOTE
If the Start-up mode is entered via Remote
Start, then only a start-up initialization
parameter “out-of-tolerance” failure and
“Remote Start binary input not low” will
exit Start-up mode and prevent entering
Waiting mode. Otherwise, the Compass
Controller will maintain Start-up mode status while waiting for allowable conditions
to begin initializing Waiting mode.
It is during Start-up mode that system integrity is
verified. System integrity verification involves checks
of functional instrumentation, communication status,
and confirmation of proper initial parameter settings.
33
COMPASS CONTROLLER USER MANUAL
A successful completion of Start-up mode transitions
the Compass Controller to the Waiting mode.
When the controller is in Waiting mode the LCD
display will indicate that the system is ready to be
started, as shown below.

Waiting mode is a transitional state between
initialization of the Compass Controller, operation of
the compressor and compressor shutdown.
In
Waiting mode, the Compass Controller is ready to
enter an operational state. However, the compressor
is not active in Waiting mode. Waiting mode is
characterized by “Ready… ” appearing on the LCD
1st line parameter display. If Remote Start is
configured then “Ready… r. ” will be displayed.

trickle charge must be applied to the batteries in order for the compressor to
maintain Start-up readiness.
When the appropriate remote start conditions are
met, the system will automatically enter the Start-up
mode, and the compressor will start.
While the compressor is attempting to start in both
Manual and Remote start mode, the LCD will display

analyzing specific system parameters to determine if
entering Sleep mode is allowable.
When the
necessary conditions are met, the system enters

energized. If the compressor was enabled via
Remote Start, the Start/On/Off switch is disabled and
only a compressor malfunction will allow entering
Waiting mode and then Sleep mode.
FAILURE TO START
In manual mode, if the engine does not start, the
Compass Controller will attempt another start cycle
as long as the maximum number of crank attempts is
not exceeded. This is an automatic process until the
Start attempts equal the set maximum.
If the maximum number of crank cycle attempts (a
preset value) is exceeded, the system will display an
error message in the LCD display as shown below,
and the system will wait until the “Reset” switch is
pressed. Once the “Reset” switch is pressed, the
Compass Controller system will shut down. Restart
the compressor by switching the Start/On switch to
ON.
In Run mode, the compressor is ready to supply
service air. The engine RPM will automatically be
adjusted to maintain the desired air pressure. If the
2nd line scroll (UCP) has been turned on, the
operator can scroll thru the list of available
parameters by momentarily pressing the “m” button.
Each press of <5 seconds will scroll one parameter.
The available parameters are listed below.

COMPASS CONTROLLER USER MANUAL
AUTO-START (REMOTE) OPERATION
When using the Auto-Start feature, there are two
parameters that can be set by using the Compass
Controller Communicator Software tool on a laptop
computer. The first is the P1 System Service Pressure, and the second is the time duration that the
compressor must stay at or above the P1 pressure.
These values are settable when the Compass Communicator software and communication adapter are
installed. When the compressor is operating in AutoStart Mode, it will not enter a normal Shutdown
mode until both conditions below are met.
a. The System Service Pressure (P1) is greater
than the UCP (User Configurable Parameter) specified level for the UCP specified
duration.
b. The “Remote Start” input has returned to its
normally open position.
In the event that an abnormal shutdown occurs, the
compressor could shut down without these
conditions being met.
See Section 5:
TroubleShooting for handling abnormal shutdowns.
SHUT DOWN
The Shutdown mode can be entered when either of
the following conditions occurs:
If the Compass Controller system was started manually, the operator must press the “Off/On/Start”
switch to the OFF position.
If the Compass Controller system was auto-started
(Remote), the system will enter Shutdown mode
when both the Service Pressure (P1) is greater than
the specified level for the user-specified duration
(Note: Both of these values are pre-set), and when
the remote start binary input is deactivated.
When the system enters the Shutdown mode, the
compressor will complete the following tasks before
shutting down:
1. The LCD will display the message shown
below.
Stop Initiated
Cool Down Cycle
1400 rpm
36
eng speed
SECTION 4
2. The engine will go to the low idle setting
(1400 RPM) for a preset period of time.
3. When the cool-down cycle is complete, the
engine will shut down.
4. The Compass Controller will continue to
monitor P1, P2, and P3 inputs until they fall
below the specified level (Note: This value is
pre-set), and the LCD will display a message
similar to the one shown below.
Monitoring Pressures
0 PSI
Serv Pres …
This is displayed as a safety measure that
indicates to the user that the system is under
pressure.
5. When the system pressures fall below the
pre-determined levels, the controller will
enter Sleep mode.
NOTE
If while the engine is cooling down during
the normal shutdown phase, but is still
running, the operator presses the "Off /
On / Start" switch back to the momentary
"Start" position (or if the Remote Start
input becomes active and the Compass
Controller is configured to accept Remote
Start), the system will immediately reenter the Warm Up phase of the Start-up
mode.
However, during the final portion of shutdown, after
the Compass Controller has stopped the
compressor’s engine, the Compass Controller no
longer pays attention to the "Off / On / Start" switch
(or Remote Start). The operator must wait until this
phase completes to restart the compressor.

POWER-UP OPTIONS MENU
Master Gauge –Service Air pressure
The menu is activated by pressing and holding down
both the “m” and “t” buttons while powering-on the
Compass Controller by pressing the “Off/On/Start”
button on the front panel.
When performed, the
following “yes/no” options will appear. The current
setting (either yes or no) is displayed in reverse
characters.
The air pressure gauge is driven by the air pressure
sender analog input. Open and shorts of the P1
Pressure sender analog input are considered out of
range and will force the pointer to fluctuate full scale.

Temperature and Fuel Level. Compressor
Temperature and Fuel Level are driven by analog
inputs. Open and shorts of the fuel level sender
analog input are considered out of range and will
force the pointer to fluctuate full scale.
MESSAGE DISPLAY CENTER
The message display consists of a graphical, backlit,
LCD display on the master gauge. Two input buttons
located directly below the LCD, the “m” (mode) and
“t” (task) buttons, allow user to navigate through the
LCD display.
As the Compass Controller system is executing in
any of its states, the LCD displays information to the
user that is pertinent to its operation and the
compressor state. In addition, through navigation
with the “m” and “t” buttons, menus may be solicited
to alter system behavior, modify the information
displayed, and make selection of the display
parameters.
PRIORITY MESSAGES
Priority messages are displayed in the LCD due to
various inputs or data messages. The priority
message will take over the second line (parameter
line) of the screen. Multiple messages may be
displayed by continually showing the message for 2
seconds before displaying the next message. Some
messages can be acknowledged by pressing the “m”
button while the message is being displayed. Once
acknowledged, the priority message will leave the
display. Certain acknowledged priority messages
may redisplay if the condition still exists after three
minutes, others will not reoccur until the next key-on
cycle.
Navigation of the menu is as follows:
• Press “m” to move circularly through the
options.
• Press “t” to toggle the yes / no setting of
the current option
• Press both “m” and “t” to exit the menu,
saving the current settings in the Compass
Controller’s non-volatile memory.
Momentary Start - When “Yes” is selected and
Remote Start is enabled, the remote stop will operate
as outlined in the Auto-Start (Remote) Operation in
this section. Alternatively, if Momentary Start is set to
“No”, the remote start input will act in the same
manner as the Off/On/Start switch on the panel in
that if the circuit is closed the machine will start and if
the circuit is opened then the machine will go into
shutdown mode and ultimately power down.

MAIN SCREEN WHILE NOT IN RUNNING STATE
Prior to transitioning into the Running state, the
Compass Controller displays messaging indicating
the operational state of the Compass Controller
system. For example, while in the System Pressure
Checking phase of the System Power-up, Check &
Initialize state, the Compass Controller will indicate
“Checking Pressures” on the LCD display. During the
Engine Cranking phase of the Starting state, the
Compass Controller displays “Cranking Engine”.
Gauge backlighting is a user configurable parameter
specified using a menu entry. Lower and upper levels
of the UCP are 60% and 90% intensity, respectively.
The specific parameter value is stored in the
Compass Controller (EEprom) memory.

TROUBLESHOOTING
INTRODUCTION
This Troubleshooting section is provided as a guide
to aid in diagnosing and resolving compressor
problems when they occur.
The information
contained in Table 5A, Troubleshooting Guide, has
been compiled from factory experience and contains
symptoms and usual causes for the described
problems. Each warning or fault message is listed
with conditions of when the problem may occur, a
probable cause, and a suggested solution to the
problem. DO NOT assume that these are the only
problems that may occur. This document cannot
address every possible adverse condition that may
occur nor does it provide every solution for the
potential troubles listed.
All available data
concerning the trouble should be systematically
analyzed before undertaking any repairs or
component replacement procedures.
Always perform a detailed visual inspection when a
machine problem occurs prior to attempting any
repairs. Doing so may avoid unnecessary repair
and/or additional damage to the compressor.
Always remember to:
a. Check for loose wiring, loss of ground, wire
termination, etc.
b. Check for damaged piping.
c. Check for parts damaged by heat or an electrical short circuit, usually apparent by discoloration or a burnt odor.
Should your problem persist after making the
recommended check, consult your nearest Sullair
Distributor or the Sullair Corporation factory Service
Department.
NOTE
Section 5.3 portrays common systematic
problems that can occur during controller
operation. For a more thoroughly in-depth
coverage of the compressor operation troubles, consult the Troubleshooting Section in
the machine’s operator’s manual.

TROUBLESHOOTING GUIDE
INTRODUCTION
The following guide contains symptoms and usual
causes for the problems that may occur throughout
the compressor system. Each warning or fault
message that may appear is listed along with
conditions for the problem, a probable cause, and a
suggested solution to the problem. DO NOT assume
that these are the only troubles that may occur. The
following table denotes all warning/shutdown
conditions that the Compass Controller will sense.
Shutdown conditions will display the associated
message on the LCD, light the Compressor
Shutdown panel light, shut the system down, and
wait for operator to press the Fault/Reset button to
acknowledge the fault condition before a restart may
be attempted. Warning conditions display the
associated message on the LCD and light the
Compressor Warning panel light. Under a warning
condition the system will continue to operate
normally. In addition, the operator may dismiss the
warning message from the LCD screen by pressing
the “m” (mode) and “t” (trip) buttons on the master
gauge.
