TROUBLESHOOTING -- USING THE EZ-CAL WITH THE FLOW CHARTS USING THE EZ-CAL WITH THE FLOW CHARTS Use the EZ-Cal Flow Charts as a guide to locate diagnostic information and make adjustments. Each box in the flow chart will have bits of information. 5C- Identification Number UP MAX Personality 75% Default Setting Figure -8: EZ-Cal Display Example to match with information tables, this number will not appear on the EZ-Cal display The IDENTIFIER (5c): Used to locate this specific personality in the informational charts. Here you can obtain specific information on the individual personalities. The PERSONALITY (Up Max): Identifies the individual personalities. The DEFAULT SETTING: The factory setting. If adjustments are made, they must be returned to default setting. ART_8 ACCESS LEVEL PROVIDES ACCESS TO CHANGE PERSONALITIES NORMALLY PRESET AT THE FACTORY TO PROVIDE PROPER MACHINE MOVEMENT AT SAFE SPEEDS. PERSONALITIES MUST NOT BE CHANGED WITHOUT PRIOR AUTHORIZATION FROM MEC AND MAY ONLY BE RETURNED TO FACTORY SPECIFICATION AS LISTED IN THE FOLLOWING TABLES. ERROR MESSAGES To obtain error messages from the EZ-Cal, access the EZ-Cal as mentioned above. The display will read, HELP:PRESS. Press Enter to display the current error message. If an error message is present, use the following list of error messages to better understand the fault. If an error message is not present, the display will show the last operation performed. Pressing Enter twice will provide a log of previous errors and operations that may have occurred within recent operation. The first message will be the most recent. FLASH CODES Flash Codes, provided from the GP00 red LED, will also assist in the event an EZ-Cal is not available. However, the EZ-Cal yields considerably more relevant information.

TROUBLESHOOTING -- EZ-CAL MESSAGES EZ-CAL MESSAGES "Help Messages" will appear on the EZ-Cal scan tool as a means of explaining operating and non-operating function(s) and system errors or interruptions that are accompanied by flash codes. It can also be used for verifying system operation. On Titan models, the EZ-Cal is conveniently located inside the lower control box. Refer to the EZ-Cal Instruction page for additional help with EZ-Cal operation. To access messages, power the system up, (it is not necessary to have the engine running) the EZ-Cal display will illuminate and read "HELP - PRESS ". Press to view current message. Press a second time then use right and left arrow buttons to access up 0 logged messages from the memory. Many messages simply detail operations being performed by the GP00; other messages detail occurrences that also take place during operation either normal or may be symptomatic of a malfunction. OPERATIONAL MESSAGES The following messages appear as result of normal operation and usually do not represent a problem. EVERYTHING OK Flash Code: None All circuits performing properly, no current operation performed. GROUND MODE ACTIVE Flash Code: None Base/Platform selector switch set to base control station. STARTUP Flash Code: None GP00 performing start up procedure, normally a short sequence. MOVING FRAME Flash Code: None Chassis level in progress. MOVING PLATFORM Flash Code: None Platform level in progress TELESCOPING Flash Code: None Boom extend/retract (telescope) in progress LIFTING Flash Code: None Boom lift up in progress LOWERING Flash Code: None Boom Lower down in progress DRIVING Flash Code: None Drive forward or reverse in progress VEHICLE TILTED Flash Code: None Chassis is tilted beyond pre-set maximum. Use auto-level feature to level chassis or re-position the machine. CAN BUS RELATED MESSAGES CAN bus communication system is the network by which the control modules and CAN Tilt modules communicate with the GP00.

Flash Code: 6/6 The CAN bus cable may be damaged or disconnected from one or more of the modules. All modules must be connected to the CAN bus for machine operation. CALIBRATION RELATED MESSAGES The following messages appear when the GP00 microprocessor has not been calibrated or was improperly calibrated. FACTORY OVERRIDE FAST FLASH GP00 is shipped in this condition to allow temporary operation of the machine without interruption from the safety system so that calibration procedures can be performed. The GP00 must be prepared for the machine to which it will be installed, including calibration and Customer/model selection. See "GP00 Setup" for instructions. Once Calibrated, Factory Override is gone forever. ALL SAFETY SETTINGS ARE INACTIVE WHEN THE GP00 IS IN FACTORY OVERRIDE, NEVER OPERATE MACHINE IN FACTORY OVERRIDE EXCEPT TO CALIBRATE THE GP00. NOT CALIBRATED Flash Code: / The GP 00 microprocessor has not been calibrated. Operation will be restricted until calibration is completed. Refer to "Set up procedures" in this section for calibration information and instructions. HEIGHT NOT CALIBRATED Flash Code: / The Height portion of the calibration has not been completed. Operation will be restricted until calibration is completed. Refer to "Set up procedures" in this section for calibration information and instructions. FUNCTIONS LOCKED - NOT CALIBRATED Flash Code: / The GP 00 microprocessor has not been calibrated. Operation will be restricted until calibration is completed. Refer to "Set up procedures" in this section for calibration instructions. FAULT: CUSTOMER Flash Code: / Customer vs. Model settings not correct.

FUNCTIONS LOCKED - TOO HIGH Flash Code: / Elevation sensor indicating elevation beyond 98%. Height Calibration performed incorrectly; Angle Transducer loose or remounted incorrectly or extend proximity switch/s failure. Use EZ- Cal in conjunction with EZ-Cal Flow Charts to identify GP00 or GP0 for sensor's inputs to check sensor readings. FUNCTIONS LOCKED - EXTERNAL SHUTDOWN Flash Code: / Boom not retracted or axle/s off level. Boom must be retracted to allow frame level, drive or outrigger operation. Axles must be centered before drive is allowed when the platform is elevated. Also, drive will be interrupted if Stabilizer pressure sensor output is below 0. volts (possible sensor failure or sensor wiring issue). CHECK DRIVE/STEER SWITCHES Flash Code: / Drive joystick output without enable or during power up. Check drive joystick analog output and steer switch digital output using the EZ-Cal. CHECK LIFT SWITCHES Flash Code: / Lift joystick or toggle switch movement without enable or during power up. Check joystick analog output using the EZ-Cal.

TROUBLESHOOTING -- TROUBLESHOOTING CHART TROUBLESHOOTING CHART The following chart describes the possible causes for inoperation of the different functions of the Titan Boom 60-S. The Causes and Solutions columns list various points of references that can be found in the Hydraulic, Electrical, Schematics and Troubleshooting sections of this manual. The majority of electrical troubleshooting on this model will require the use of the onboard EZ-Cal scan tool, located inside the lower control box door. Please refer to "EZ- Cal Scan Tools" on page -8 for further instructions on the use of the EZ-Cal scan tool. Perform a full assessment of machine operations prior to troubleshooting this model and using this chart. This model is operated by a Microprocessor Control System equipped with a variety of built-in safety interlocks to prevent continued operation in the event of a failure or misoperation. Some interlocks may only be detected through the use of the EZ-Cal.

Variable elevated speed Variable hydraulic oil temperature Out of the stowed position, each machine is set to drive 0m ( ft) in 0 seconds with the hydraulic oil at 50 C ( F), at a speed of. m/s (.7 mph). Through testing, this setting causes the speed to increase to 0m in 5 seconds [.0 m/s (.9 mph)] at an oil temperature of 0 C (68 F), and 0m in 8 seconds [.55 m/s (. mph)] at an oil temperature of 0 C ( F). Although colder ambient temperatures are likely, once the engine has started and hydraulic oil has been circulating, it very quickly reaches 0 C ( F) and therefore the elevated driving speed should not exceed.7 m/s (.57 mph).
