How do I interpret the status and trouble lights on the Spectrum 375?

The Power light indicates input power status. The Pressure, Cup, and Temperature lights indicate system conditions. A steady Power light means input power is okay and the system is normal if Pressure/Cup/Temp lights are off. When the Pressure light is on, it indicates no or low (below 40 psi) input pressure. When the Cup light is on, the torch cup is loose or off. When the Temperature light is on, the power source has overheated and needs to cool down. Flashing lights indicate specific fault conditions that require checking consumables, torch, or input pressure. (Page 27)
