Problem Solving (Troubleshooting)
-
The power light does not turn on: Check if the emergency stop button is pressed or if the key is in the center position.
-
Invalid platform operations: Verify that the key is in the "Platform" position and that the system has been reset after an update.
-
The platform does not rise to the maximum (Indoor): Recalibrate the height or adjust the travel switch.
-
Forward/backward movement not working: Check PWM connectors of the proportional solenoid valve on the carriage.
Important Notes
- For any error code, always consult the manufacturer's manual.
- If the problem persists after applying the solution, contact technical support.
- Keep a record of error codes to facilitate preventative maintenance.
