Power and Control Box — Decode Control Box Beep Codes

Power cycle the Control Box to allow it to reboot.
While the Control Box is rebooting, it will perform a self test and report any errors with long and/or short beeps.

Long Beeps	Details
*_ One Long:* Using firmware from bank 1 Normal Startup	For redundancy, each controller has two firmware banks. Either of them can be used during startup.
*_ _ Two Long:* Using firmware from bank 2 Normal Startup	For redundancy, each controller has two firmware banks. Either of them can be used during startup.
*_ _ _ Three Long:* Control Box is not powered USB is connected to the control box, but there is no external power to the control box. It is normal to hear the beeps when you turn OFF the control box and keep the USB cord connected. After it the controller might reboot and beep about firmware bank and again for no power present.	If the Control Box power is ON, the is a potential power issue due to: EMERGENCY STOP button pressed (reset to enable power) Bad AC power cable (verify cable is seated properly and not damaged) Bad power switch on the control box If fans are spinning in the control box, it could potentially be a faulty internal power supply on the motherboard inside the control box.

**_ _ _ _ Four Long:** Firmware issue detected	Firmware model configuration not present. Contact DOF Reality Technical Support

Example: Two long beeps after the control box powered – the firmware from bank 2 is used.

Short Beeps	Details
*– One Short:* Feedback sensor issue	One, two or three long beeps refers to the specific motor/port number. Check sensor phone connector and wire.
– – Two Short: Motor self-calibration issue	One, two or three long beeps refers to the specific motor/port number. Check that nothing blocks the motor and gearbox from moving both directions. Check the motor power connector and cable. Check platform weight balance.
– – – Three Short: Motor or power issue	One, two or three long beeps refers to the specific motor/port number. Motor is not performing as it should. Check the motor power connector and cable. Check platform weight balance.

Example: Two short and three long beeps – there is an issue with motor/port 3 calibration.
