Power supply protection

• If the main unit connects to other devices such as the external parameter module, USB drive, and scanner, first disconnect these devices from the main unit. If the monitor can be started after the disconnection, an external device may fail, leading to power supply protection.

• If the main unit is not connected to other devices, check whether there is any short circuit fault in the internal module rack backpane or main control board and it leads to protection of the power output.
