7.2.3 ANALYZER
7.2.3.1 GENERALAnalyzer function supports operations for inspecting/investigating faulty section by displaying the condition ofthe control system, using communication between each controller and the multi-function display DX.By switching the multi-function display DX to analyzer mode, operative conditions of the sensor actuator thatis used for traveling, material handling, FHPS and SAS/OPS functions, or the error information detected bythe controller can be read. This is very useful for checking operative condition of each function and savingtime for repairing when there is a defect.Full utilization of the analyzer functions helps quick, easy servicing.The analyzer has the following functions:1. Diagnosis memory function "DIAG MEMORY"
The controller stores up to 10 error codes (diagnosis codes) detected in the electrical system in the past.The diagnosis function reads these error codes and indicates them on the display.Each error code is displayed with its detection time as the key ON hour meter reading.
2. In/Out monitor function "I/O MONITOR"This function displays the analog input values from individual sensors in the traveling, material handling,FHPS, SAS and OPS systems. Monitoring the displayed values enables the quality of each circuit/sensorto be judged.(1) "I/O ENGINE CTRL"Displays ON/OFF states of the engine controller switch, various input values including analog inputvoltage from the sensor and correction value of the control.(2) "I/O TRAVELING"Displays each switch ON/OFF state and analog input voltages from sensors for traveling and swing con-trol.(3) "I/O M.HANDLING"Displays the material handling and mast switch ON/OFF states and analog input voltages from materialhandling and mast sensors.(4) "I/O STEERING"Displays the ON/OFF states of knob position correction control and the analog input voltages from re-spective sensors.(5) "I/O OTHERS"Displays the ON/OFF states of hour meter time and other switches and the analog input voltages fromrespective sensors.
3. Active test "ACTIVE TEST"In the active test mode, the controller forcibly outputs an activation signal (ON or OFF signal) to the se-lected item in order to permit operation check of that function.
4. Program version display "VERSION"Displays program version of each controller.

7.2.6 MATCHING
7.2.6.1 GENERAL For the tilt angle, load and tire angle sensors among sensors used for SAS functions, the signal voltage
values under the mast vertical, no load and tire straight conditions are stored, respectively, in the control-ler for the control based on these values. When servicing or replacing these sensors, matching (updatingthe sensor signal voltage value in the standard vehicle condition) is necessary. Also, matching is neededfor the tilt angle sensor when the vehicle posture has changed excessively, and for the load sensor whenthe load under no load condition (no load on fork) is changed because of addition or removal of any at-tachment.
Each lever angle sensor for mini lever is controlled based on the memory of signal voltage values in theneutral position stored in the controller at the time of shipment. When servicing these sensors or repla-cing related parts, MATCHING (updating the sensor signal voltage value in the standard vehicle condi-tion) is necessary.
Solenoid current level for the electromagnetic relief valve (EMRV) is set for each electromagnetic reliefvalve, before shipping, and it is registered to SAS/OPS controller.So "MATCHING" is necessary when maintaining or replacing parts for electromagnetic relief valve(EMRV).

7.2.6.3 BEFORE STARTING MATCHINGSet the vehicle to "Standard vehicle condition" before starting matching."Standard vehicle condition" means that the vehicle satisfies the conditions described below.
Standard vehicle conditionNOTICE:
Items 1 to 4 below show the standard vehicle condition for SAS matching. Before carrying out matching for mini lever/joystick vehicles, move the armrest to the driving po-
sition and check the neutral state of the levers. In case of a detachable attachment, keep the attachment installed on the vehicle.
Level surface
1. Tire pressure checkAdjust the tire pressure to the specified level. Match-ing will be inaccurate if the pressure is low, or if thereare air pressure fluctuations between front and rearas well as left and right.
2. Surface levelness checkIf matching is conducted on an inclined or rough floorsurface, errors in standard vehicle condition will oc-cur, so perform matching on a flat, level surface (in-clination: within 0.5°).

3. No-load vertical condition checkStore the output voltage of the load sensor in no-loadstate in the controller. At this time, the following con-ditions must be satisfied:
For the V mast, set the lifting height to about 500mm (19.7 in) and use a goniometer to check thatthe mast is vertical.
For the FV/FSV mast, set the rear cylinder rodprojection to about 100 mm (3.93 in) and use agoniometer to check that the mast is vertical.
On a vehicle with attachment , set the mast ver-tical with the attachment at a height of 500 mm(19.7 in) and perform relief at the topmost posi-tion.
Set the mast in the vertical position from thebackward tilted position by operating the tilt leverin the forward tilting direction.

4. Tire straight traveling position checkStore the tire angle sensor output voltage in the con-troller in the condition of the vehicle traveling straightahead. Condition of the vehicle traveling straight aheadmeans that the deviance to left or right is within 50mm (2.0 in) when the vehicle travels for 5 meters (16ft) with the steering being fixed.
