When the DC power supply opens to generator immediately hit exactly (engine not working)

1, check the MPU have to use the appropriate isolation wire or strip away shielding, check the wiring in accordance with the need to fix wiring confirmation no jumper between terminals 2 and 3, check the connection or in accordance with the need to repair.

2,Generator controller safety protection circuit may be damaged or defective, replace the generator controller.

3, under the DC power supply shut down pull out actuator lead, check each conductive terminals on the shell.Any terminal for the shell should be cannot conduct electricity generator controller, if the shell can be conductive, replace the controller.

4, if speed control potentiometer is receiving the terminal of the controller 6, 7 and 9 is dismantle such some lead first, open the speed of DC power supply, if the actuator movement is normal, check the external potentiometer and connecting the following narrative.

Governor completely motionless, and when there is a power delivery to generator is still stopped at the minimum position.

1, check the battery voltage on the controller terminals 1 and 2, terminal 1 for power supply, check the battery terminal and the contact point for sending to the generator controller.

2, check whether the connecting rod is appropriate - correction and unload connecting rod.

3, MPU low or no signal, when starting the engine measuring terminal 10 and 11 of the AC voltage, voltage should have at least 1 vac.(note: the impedance of the voltmeter must be greater than 5000 ohm/volt) check the clearance between the gear and the top of the MPU, should be between 0.037 mm - / - 0.037 mm.

4, measure the MPU coil resistance, resistance should be greater than 50 ohm - if there is open circuit or short circuit phenomenon MPU is replaced.

5, measure the MPU each resistance value between the pins on the metal shell, should confirm all conductive.

6, if the shell can be conductive, replace the MPU.

7, if the actuator coil open or short-circuit is replaced with the shell actuator.

If the actuator is still not move, the following steps.

8, the ohmmeter measuring scale with low actuator chart with shell resistance, if the general principles of the guide way to replace the actuator.

9, the governor has a DC power supply and the engine stops, measuring terminal 6 (+) and (-) terminal 2, should be around 4 VDC voltage, if not present 4 DVC controller is replaced.

10 and 7 in the terminal (+) and 2 (-) terminal should be measured about 4.6 VDC, if did not present 4.6 VDC generator controller is replaced.

Generator governor erratic running

1, the controller of (+) 1 and 2 (-) terminal can measure DC voltage.

2, low voltage 20% May result in erratic operation, check the battery and charging system.

3, caused by the incorrect shielding RFI (radio frequency interference), correct wiring.

4, RFI with feed with the power supply, power fuses under battery direct connection.

Due to the speed control potentiometer caused by improper operation

1, the investigation of speed control potentiometer connection is open circuit or short circuit, check the wiring.

2, if the answer to the speed control potentiometer terminals 6 and 7 reverse connection, the speed control by remote control potentiometer will instead, correct wiring.

3, lead to the speed control potentiometer wire must be a 3 core shielded wire, check this isolation in potentiometer terminal and ground insulation, if connected to the potentiometer terminal 6 open, engine speed will drop, check the wiring.

4, if lead 8, 9 (remote control potentiometer in the middle of the foot) is open circuit, speed control potentiometer will have no effect, confirm and correct the wiring.

5, if 7 lead to speed control potentiometer clockwise is open circuit, the speed will stay with the values in the controller.

6,

The speed or frequency in small increments, slowly vibration

Connecting rod stuck or is very loose, correct connecting rod.

Governor rod swing quickly

Confirm the control as the school set, if necessary, readjust.

The engine won't start - during startup actuator drive to the point of maximum fuel

1, confirm with fuel oil, and check the engine fuel, check the automatic stop circuit wiring.

2, there may be in the fuel pipe.

3, check the fuel pipe loophole, try to use manual engine.
