Err34 appears immediately at startup (without any operation)

• Fault Causes: Accelerator plug loose, accelerator failure, monitor failure.

  
  

  When the accelerator is in the neutral position, the voltage is 2.5V - 2.6V. When the accelerator is rotated forward, the voltage gradually increases to 4.5V. When the accelerator is rotated backward, the voltage gradually decreases to 0.5V.

  
  

  Troubleshooting Method 1

  Enter the stacker diagnostic interface and observe the neutral position voltage value of the accelerator on the screen and the voltage changes when rotating the accelerator forward and backward. If the voltage changes do not match the above standards, it is judged as an accelerator failure. If the voltage matches the standards, it is judged as a Monitor failure.

  
  

  Troubleshooting Method 2

  Use a multimeter to measure the neutral position voltage of the accelerator and the voltage changes when rotating the accelerator forward and backward. If it does not match the above standards, it is judged as an accelerator failure. If the voltage matches the standards, it is judged as a monitor failure.
