Pump not responding on Coulter T540

Can someone give help for "Pneumatic low" message on Coulter T540?. The pump is not operating and the 24V voltage is laking in the diagnostic screen. In the front panel connector of the power supply cage, there is no voltage between GND and 24V pin.

Can someone give help for "Pneumatic low" message on Coulter T540?. Pump: no action at startup 24V: Absent trought the diagnostic creen an also between power supply GND an 24V Pin. Other devices: No action. There is a multivoltage connector in front of the power supply cage. Is it normal that between GND and 24V pin of this connector the voltage should be 0V? Can someone send me the diagram of the power supply system? NB:[b] [i]The FAN operates only when it's connector is removed from the mainboard.[/i][/b]
