debugging, after re-energizing the unit, please conduct
debugging from the above 01 step.
No component of ODU is found in the system, it will enter
into the next step 10 seconds later.
Error of components of IDU are detected. For example, the
IDU displays d5 and d6 simultaneously, the nixie tube will
repeatedly display ―0 7‖, ―d 5‖, ―d 6‖. After eliminating all the
errors, it will automatically enter into the next step. If the
ODU should be powered off for the debugging, after

Insufficiency preheating of compressor. The nixie tube will
display as the left until the preheating time for compressor
has reached 8 hours, then press SW3 can skip over the
waiting time, and automatically enter into the next step 2
seconds later. (Note: if the preheating time for the
compressor is less than 8 hours, there may be a risk for
damage of compressor, please conduct with care)
If the ODU is continuously energized for ≥8h, or the
continous 8-hour energizing time in the last time till now is
less than 2 hours (it requires clock chip), it means the
preheating is completed, the system will automatically enter
into the next step 2 seconds later.
The system shuts down due to malfunction. The error
module nixie tube repeatedly display ―0 9‖ and ―U6‖, other
module nixie tubes repeatedly display ― 09‖ and ―J 0‖. If erroe
occurs, please check if the valve is opened, and at the same
time check if the connecting pipes between different
modules are correctly connected.
If all the modules shut down, then all the module nixie tube
will display ―0 9‖ and ―o C‖ for once.
The whole unit has gone through the debugging, the system
is in stand-by status.
