    is there some red LED lit on OPUS panel inside main control cabinet?
    a lot of suggestions.
    You need electrical diagram first.
    Check if there is +24V and -24V - it's easy just on terminals of power supply units.
    Then check contactors and trigger fuses next to these power supply units.
    Finally, check power on button on op panel - must be 24V on contacts. Check connection from the button to cable.
