SAFETY
1.1 GENERAL
Sullair designs and manufactures all of its productsso they can be operated safely. However, theresponsibility for safe operation rests with those whouse and maintain these products. The followingsafety precautions are offered as a guide which, ifconscientiously followed, will minimize the possibilityof accidents throughout the useful life of thisequipment. Read the CIMA Safety Manual prior tocompressor operation and towing, if applicablein your area.
The air compressor should be operated only by thosewho have been trained and delegated to do so, andwho have read and understood this Operator’sManual. Failure to follow the instructions, proceduresand safety precautions in this manual can result inaccidents and injuries.
NEVER start the air compressor unless it is safe todo so. DO NOT attempt to operate the aircompressor with a known unsafe condition. Tag theair compressor and render it inoperative bydisconnecting the battery so others who may notknow of the unsafe condition will not attempt tooperate it until the condition is corrected.
Use and operate the air compressor only in fullcompliance with all pertinent OSHA requirements
and/or all pertinent Federal, State and Local codes orrequirements.
DO NOT modify the compressor except with writtenfactory approval.
Each day, walk around the air compressor andinspect for leaks, loose or missing parts, damagedparts or parts out of adjustment. Perform allrecommended daily maintenance.
Inspect for torn, frayed, blistered or otherwisedeteriorated and degraded hoses. Replace asrequired.
1.2 TOWING
PREPARING TO TOW
NOTE
OPERATOR IS REQUIRED TO READ ENTIRE INSTRUCTION MANUAL.
CAUTIONEstimated 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 8-hour shifts would shorten the hose life based on hours of operation.
(I)
WARNINGDo 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.

1.6.1 TIER 4 EMISSIONS MODULE
General Guidelines: Thermal Protection. The mainexhaust piping routes exhaust gas from the engine tothe Clean Emissions Module (CEM). Normaloperating temperatures can reach up to 530 °C (986°F). During regeneration of the Diesel ParticulateFilter (DPF), the Auxiliary Regeneration Device(ARD) will be in operation, this creating temperaturesabove normal engine exhaust temperatures. Gastemperatures during the regeneration period canreach 750 °C (1382 °F).
WARNINGIncreased DPF skin temperature and exhaust gas temperature may occur in the event of an unexpected engine/aftertreat-ment failure. An unexpected failure of the engine/aftertreatment may increase temper-ature at the DPF as high as 900 °C (1652 °F) gas temperature and 750 °C (1382 °F) skin temperature. This may result in fire, burn, or explosion hazards, which may result in per-sonal injury or death. Do not expose flam-mable material or explosive atmospheres to exhaust gas or exhaust system components during regeneration. The aftertreatment skin temperature and the gas temperature are difficult to measure and/or simulate and are dependent upon many factors including the following: the nature of the engine/after-treatment failure, the design and packaging of the aftertreatment, the engine speed/load conditions, the condition of the aftertreat-ment and ambient conditions. Therefore, the potential temperatures are provided as a guideline even under conditions of unex-pected engine and/or aftertreatment failure. Proper precautions should be taken to ensure that the aftertreatment device is not mounted in close proximity to components that may be damaged by heat.

This compressor is equipped with a Sullair CompassController for controlling the compressor systemoperation, adjusting the machine parameters andperforming maintenance operations. The CompassController utilizes digital technology that ensuresaccurate and safe operation of the compressorsystem. When fault conditions occur, the controllerautomatically shuts down the machine to preventinjury to the operator or damage to the equipment.Features of the Compass Controller include:
• Dual gauges for display of pressure,engine temp, compressor temp, enginerpm, and fuel level
• LCD screen displaying machine status andoperating information
• Remote start capabilities
• Automatic self diagnosis at startup
• Multiple language support
• An external diagnostics port which allowsPC interface for configuration of the systemparameters.
• Backlighting of gauges with green LED toallow clear view of gauges in low lightareas.
2.2 CONTROLLER PANEL LAYOUT
The Compass Controller panel is shown in Figure 2-1. The controller components and functions aredescribed in detail in Section 4.
2.3 COMPASS CONTROLLER POWER UP
The compass controller is used to start thecompressor either manually or remotely.
Manual Start: Start the machine by pressing the
“OFF/ON/START” button to the “START” position onthe controller panel. Once the switch has been set tothe START position and the controller hassuccessfully initialized (see Self Test, Bus Checks,Safety Checks this section for further information),the Compass Controller will check status, then willautomatically continue to energize the starter untileither the engine starts or the maximum crankduration is reached.
Auto Start: The compressor can be startedremotely if the remote start function has beenenabled during setup. If this option is activated, an
“ ” will display in characters in the upperright corner of the LCD display.
SELF TEST
When the controller is initially powered up, thesystem will initiate a “Self Test” sequence to verify itsoperational integrity and safety status. During thisprocess, the following self tests will be performed.
1. Gauge pointers will move to the zero posi-tion, then to half and full scale, then back tozero, and finally to the actual value reading.
2. The LCD display will turn on all its segmentsfor one second, off for one second, and thendisplay the Sullair logo followed by the soft-ware product number with revision level.
3. All warning lights will turn on for 5 secondsand then turn off, then set to the actual indi-cator state.
The Self Test feature may be bypassed by disablingthe sequence as describe in Section 3 of thismanual.

PRESSURE CALIBRATION
Over time the P1, P2, and P3 pressure transducervalues might drift resulting in an inaccurate readingshowing on the pressure gauge. Using the PressureCalibration function the operator can adjust theactual zero pressure to 0.00 BAR when no pressureis present in the compressor. The offset value will besubtracted from the transducer value to obtain anadjusted reading used for indication and calculation.
To calibrate a pressure transducer:
1. Select the transducer (P1, P2, or P3) to becalibrated by pressing both the “m” and “t”buttons at the same time.
2. The following screen sequence will be pre-sented (example below). This exampleshows a P1 pressure of .60 BAR on amachine that is known to actually be at zeropressure. The current pressure value is dis-played in metric units only (1 kPa = 0.01bar).
3. Calibrate the actual pressure reading backdown to 0.00 by increasing the value of thecorrection / offset by pressing the “t” buttonuntil the Actual Pressure reads 0.00. Oncethis is done, simply press both the “m” and“t” buttons together to store this value in thesystem. The offset value will be subtractedfrom the transducer value to obtain theadjusted reading. The calibration offset isconfigurable in steps of -50 to +50 with 0 thefactory default. Each step is approximatelyequal to ±1 kPa (±0.15 psi) on machinesless than 300 psi and ±3.25 kPa (±0.47 psi)on machines over 300 psi.
AUXILIARY TEMPERATURE CALIBRATION
Occasionally, and when the auxiliary temperatureinput is first configured, the input may requirecalibration to adjust the input to the actual knowntemperature. This is accomplished using theAuxiliary Temperature Calibration function. Theauxiliary temperature calibration offset isconfigurable in 0.5°C increments. A total offset of +/-10°C is allowable. The offset will be applied to theRTD input signal and used for indication andcalculation during compressor operation.
To calibrate the Auxiliary Temperature input:
1. Select the Aux Temp input by simultaneouslypressing both the “m” and “t” buttons whenthe input is highlighted.
2. The following screen will be presented(example).
3. Adjust the offset value using the m and t but-tons.

COMPASS CONTROLLER USER MANUAL
DESCRIPTION4.1 INTRODUCTION
This section describes the operation of the CompassController, the function of the controller components,and the various types of displays that may appear onthe display screen. Descriptive lists of all messagesappearing in the display are also provided.
4.2 OPERATING MODES
SLEEP MODE
Sleep mode occurs when the Compass Controller isnot powered on. All electrical components areinactive during Sleep mode to prevent batterydrainage (i.e. microprocessor, relays, indicationlamps, etc).
Sleep mode is dependent upon the position of theOff/On/Start switch and current operating status ofthe compressor. If the compressor is in any stateother than running, then placing the Off/On/Startswitch in the OFF position will enter Sleep mode. Ifthe compressor is running, placing the Off/On/Startswitch in the OFF position will initiate Cooldownmode followed by Sleep mode.
If the compressor has shutdown due to faultcondition, then the fault must be acknowledged bypressing the reset switch and switching the Off/On/Start switch to the OFF position.
If the compressor was enabled via Remote Start, acompressor malfunction will allow entering Readymode only. The malfunction must be acknowledgedby pressing the Reset switch and Off/On/Start switchmust be in the OFF position to enter into Sleepmode.
START-UP MODE
Start-up mode initializes the system instrumentationcomponents for operation. Start-up mode is internalto the Compass Controller and does not permitengine/compressor activation.
Start-up mode is enabled by one of the followingtwo methods:
1. Press the Off/On/Start switch to ON.
2. Activating the Remote Start switch (ifenabled).
Placing the Off/On/Start switch to the ON position willenergize the Master Gauge and begin initializing thesystem for Ready mode.
If Start-up is entered by placing the Off/On/Startswitch in the ON position, placing the switch in theOFF position powers down the entire system. If astart-up initialization parameter is out-of-tolerance,the Compass Controller will enter a safe-shutdownstate and demand user interaction to completelypower down the unit.
It is during Start-up mode that system integrity isverified. System integrity verification involves checksof functional instrumentation, communication status,and confirmation of proper initial parameter settings.A successful completion of Start-up mode transitionsthe Compass Controller to the Ready mode.
NOTEIf 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 sta-tus while waiting for allowable conditions to begin initializing Waiting mode.
COMPASS CONTROLLER USER MANUAL SECTION 4
36
READY MODE
When the controller is in Ready mode the LCDdisplay will indicate that the system is ready to bestarted, as shown below.
The compressor can be started in one of the twoways as described in Section 2. When the
compressor is waiting to be started remotely, an “ ”in the upper right corner of the LCD will display in
characters as shown below.
When the appropriate remote start conditions aremet, the system will automatically enter the Start-upmode, and the compressor will start.
While the compressor is attempting to start in bothManual and Remote start mode, the LCD will displaythe following:
Ready mode is a transitional state betweeninitialization of the Compass Controller, operation ofthe compressor and compressor shutdown. InReady mode, the Compass Controller is ready toenter an operational state. However, the compressoris not active in Ready mode. Ready mode ischaracterized by “Ready… ” appearing on the LCD1st line parameter display. If Remote Start is
configured then “Ready… ” will be displayed.
Ready mode to Run mode is dependent on userinitiation of a compressor start enabler.
• Manual Start – initiated by the Start/Onswitch placed in the Start position.
• Auto (Remote) Start or Remote StartMomentary – Remote Start enabled.
In Ready mode, the Compass Controller is analyzingspecific system parameters to determine if enteringSleep mode is allowable. When the necessaryconditions are met, the system enters Sleep modeand all electrical components are de-energized. Ifthe compressor was enabled via Remote Start, theStart/On/Off switch is disabled and only acompressor malfunction will allow entering Ready
NOTEFor remote start applications, an appro-priate trickle charge must be applied to the batteries in order for the compressor to maintain Start-up readiness.If configured for remote start, the inactiv-ity auto sleep UCP is disregarded and no auto-sleep transitions will occure.

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 (apreset value) is exceeded, the system will display anerror message in the LCD display as shown below,and the system will wait until the “Reset” switch ispressed. Once the “Reset” switch is pressed, theCompass Controller system will shut down. Restartthe compressor by switching the Start/On switch toON.
When Remote is enabled, if the engine does notstart, the “Fault / Reset” switch will need to bedepressed to reset and shut the machine down. Thesystem will then wait for the appropriate start-upconditions and then activate the remote start input tostart the compressor.
RUN MODE
Once the compressor has completed the warm upcycle, it will phase into Run mode. When in Runmode, the LCD display will look similar to the displayshown below.
In Run mode, the compressor is ready to supplyservice air. The engine RPM will automatically beadjusted to maintain the desired air pressure. If the2nd line parameter (UCP) has been turned on, theoperator can scroll thru the list of availableparameters by momentarily pressing the “m” button.Each press of <5 seconds will scroll one parameter.The available parameters are listed below.

AUTO-START (REMOTE) CONFIGURATION
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 Pres-sure, 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 Com-municator software and communication adapter are installed. When the compressor is operating in Auto-Start Mode, it will not enter a normal Shutdown mode until both conditions below are met.
a. The System Service Pressure (P1) is greaterthan the UCP (User Configurable Parame-ter) specified level for the UCP specifiedduration.
b. The “Remote Start” input has returned to itsnormally open position.
In the event that an abnormal shutdown occurs, thecompressor could shut down without theseconditions 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 manu-ally, 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 shownbelow.
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, theengine will shut down.
4. The Compass Controller will continue tomonitor P1, P2, and P3 inputs until they fallbelow the specified level (Note: This value ispre-set), and the LCD will display a messagesimilar to the one shown below.
This is displayed as a safety measure thatindicates to the user that the system is underpressure.
5. When the system pressures fall below thepre-determined levels, the controller willenter Sleep mode.
However, during the final portion of shutdown, afterthe Compass Controller has stopped thecompressor’s engine, the Compass Controller nolonger pays attention to the "Off / On / Start" switch(or Remote Start). The operator must wait until thisphase completes to restart the compressor.
Stop Initiated Cool Down Cycle
eng speed1400 rpm
NOTEIf 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 re- enter the Warm Up phase of the Start-up mode.

GAUGES DISPLAY
Master Gauge –Service Air pressure
The air pressure gauge is driven by the air pressuresender analog input. Open and shorts of the P1Pressure sender analog input are considered out ofrange and will force the pointer to fluctuate full scale.
4-in-1 Gauge
The 4-in-1 slave gauge displays Engine CoolantTemperature, Engine Speed CompressorTemperature and Fuel Level. CompressorTemperature and Fuel Level are driven by analoginputs. Open and shorts of the fuel level senderanalog input are considered out of range and willforce 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 buttonslocated directly below the LCD, the “m” (mode) and“t” (task) buttons, allow user to navigate through theLCD display.
As the Compass Controller system is executing inany of its states, the LCD displays information to theuser that is pertinent to its operation and thecompressor state. In addition, through navigationwith the “m” and “t” buttons, menus may be solicitedto alter system behavior, modify the informationdisplayed, and make selection of the displayparameters.
PRIORITY MESSAGES
Priority messages are displayed in the LCD due tovarious inputs or data messages. The prioritymessage will take over the second line (parameterline) of the screen. Multiple messages may bedisplayed by continually showing the message for 2seconds before displaying the next message. Somemessages can be acknowledged by pressing the “m”button while the message is being displayed. Onceacknowledged, the priority message will leave thedisplay. Certain acknowledged priority messagesmay redisplay if the condition still exists after threeminutes, others will not reoccur until the next key-oncycle.
POWER-UP OPTIONS MENU
The menu is activated by pressing and holding downboth the “m” and “t” buttons while powering-on theCompass Controller by pressing the “Off/On/Start”button on the front panel. When performed, thefollowing “yes/no” options will appear. The current
setting (either yes or no) is displayed in characters.
Navigation of the menu is as follows:
• Press “m” to move circularly through theoptions.
• Press “t” to toggle the yes / no setting ofthe current option
• Press both “m” and “t” to exit the menu,saving the current settings in the CompassController’s non-volatile memory.
Momentary Start—(Only displayed when BOTHRem Start Momentary? AND Remote Start Enabled?are set to Yes). The remote stop will operate asoutlined in the Auto-Start (Remote) Operation inthis section. Alternatively, if Momentary Start is set to“No”, the remote start input will act in the samemanner as the Off/On/Start switch on the panel inthat if the circuit is closed the machine will start and ifthe circuit is opened then the machine will go intoshutdown mode and ultimately power down.

Line 2 Parameter – enables the display of anadditional compressor / engine parameter duringRunning state. The first line parameter duringRunning state is always the system service pressure(P1) The second line may display any of severalpossible parameters.
Self Test - determines whether the gauge self test isperformed at start-up upon entry to the SystemPower-up, Check & Initialize state.
Remote Start - determines whether the activation ofthe normally open low-side remote start input can
attempt to start the engine once in the Ready state.
MAIN SCREEN WHILE NOT IN RUNNING STATE
Prior to transitioning into the Running state, theCompass Controller displays messaging indicatingthe operational state of the Compass Controllersystem. For example, while in the System PressureChecking phase of the System Power-up, Check &Initialize state, the Compass Controller will indicate“Checking Pressures” on the LCD display. During theEngine Cranking phase of the Starting state, theCompass Controller displays “Cranking Engine”.
BACKLIGHTING
Gauge backlighting is a user configurable parameterspecified using a menu entry. Lower and upper levelsof the UCP are 0% to 100% intensity. The specificparameter value is stored in the Compass Controller(EEprom) memory.
GAUGES INTERNAL WARNING INDICATORS
High Coolant Temperature
The High Coolant Temperature indicator light willturn on when the Compass Controller receives thecorresponding output signal from the Caterpillarengine.

Louvers Closed Warning Informs operator of louver position. None unless machine overheats. Otherwise check Ambient Temp Sensor reading on LCD display. If the Ambient Temp reading is higher than the 70°F and the louvers are closed, check louver solenoid for proper operation. Also check louver air cylinders for proper operation. If the Ambient Temp Sensor is reading lower than atmospheric conditions, then check the temp sensor for proper operation and replace is necessary.
AC Freeze Imminent Warning If the Compass Controller is configured with an aftercooler and no louvers installed and the temperature at the discharge of the aftercooler falls below the setpoint, this message is displayed.
Bypass the aftercooler service air discharge circuit by locking out the aftercooler from the system and using non- aftercooled air.
Install Louvers on the aftercooler (if equipped) or the canopy intake.
Overflow Condition Warning A minimum service pressure must be maintained to prevent overflowing the oil separator filter. If the service pressure drops below required value for a period of 15 seconds, Compass will override any throttle control and command TSC1 to UCP Low Engine Idle. “Overflow Condition” will be displayed to inform end-user of condition. The warning message can be end-user acknowledged. Message acknowledgement does not release TSC1 control.
The service pressure must rise above the programmed set point, to normal operating pressure, for longer than 5 seconds to clear the fault condition. When the service pressure returns above the set point, throttle control reverts back to previous method and un-acknowledged warning message will clear. The 300 PSI Compass set point is 85 PSI, 600 PSI Compass set point is 150 PSI.
