Errors related to the drive board are identified and handled by the host control software in the form of error codes. Note that only some of the error codes reported to the host control software from the dive board can be handled automatically, while some need to be judged with the help of the users or service engineers. When error is reported, the error No. and error names are provided by host control software. The recommended solutions may appear on the screen as the software help information.
When you check for errors, first ensure the board is well fixed and all the error-related connections are properly connected. For example, when “Sample probe action failed” is
error causes are found and new components are replaced, you need to replace the drive board.
The error codes, error names and recommended solutions are listed in the following table.

Recommended action
0100 Valve output failed
FPGA does not allow the MCU write data into the valve-pump data register within 50ms, i.e. the serial output status indication bit in the register (which is used to judge the status of valves and pumps of FPGA) is always 1. It might be FPGA error or MCU read register error.
