When the display changes from [STEP4CPU Adjustment] to [CPU Adjustment Not Available], adjustment cannot be performed.
A (display condition) is reading the engine speed, its speed is above 850RMP, when the step motor is upshifting and downshifting, if the speed drops by 10RPM after downshifting:
Cause: The engine speed sensor has not been correctly read.
Deal with:
1. After measuring the voltage of the speed sensor and adjusting it, adjust it by line A.
2. Pull out the sensor wiring plug and take a measurement.
3. High-speed idling should be above 3V (AC) (the lowest readable voltage of the controller).
4. When the factory adjustment, tell the idling to be above 4V (AC).
5. Specified voltage: 1.4~6V (AC).
6. Resistance value 2.3; 0.2 ohm
B (display condition) When there is abnormal rotation (offset) on the idling side of the element:
Cause: The adjustment of the adjustment rod of the progressive motor is poor.
Repair:
1. After determining the adjustment link, make an A adjustment.
2. Adjust the length of the connecting rod: 288mm (SK200-6), 304mm (SK230-6), 198MM (SK320-6).
3. When the adjustment is still unbalanced, as an emergency treatment method, the buzzer stop switch is pressed once in the offset, and the virtual high-speed idling state can be entered to display [CPU adjustment end].
two. When [CPUROM Data] is displayed, adjustment cannot be made.
A (display condition) when an abnormality occurs inside the electromechanical controller.
Cause: There may be damage inside the electromechanical controller.
Disposal: When the electromechanical A adjustment is still not possible, the electromechanical controller should be replaced.
B (display condition) when the electromechanical controller is replaced.
Reason: No electromechanical A adjustment
Processing: Perform electromechanical A adjustment
When the display of [STPE 1 Adjusting Case] cannot enter the display of [STEP 2 Clearance Adjustment], adjustment cannot be performed.
(Display adjustment) The limit switch signal (ground) in the progress motor can not enter the electromechanical controller.
Cause: The limit switch in the motor is defective; the motor of the motor is defective or there is a wire break.
Remedy: Check if the limit switch of the progressive motor is in the ON or OFF position; check the wiring, wiring, etc. for adjustment.
