How to check control system before starting of cold room

Set the multi meter to voltage and check L V M common supply with neutral, if it shows voltage, we have to check N O supply. If there is voltage on N O, then our L V M is ok otherwise change the R Y B sequence.
Then we check supply in LP / HP inlet, if it’s showing voltage, we have to check LP / HP outlet. If voltage is there on output too, so our HP / LP switch is ok otherwise check both the suction and discharge pressures.
Then we check compressor overload inlet number 95. If it’s showing voltage, check the overload output number 96. If voltage is there on output too, so our compressor overload is ok. Otherwise reset the overload.
Then we have to check the controller supply. If supply is there and not showing readings on display, so check the controller display.
