Hi, we have an issue where our Turbo power supply, Pfeiffer split-flow turbo, +48 VDC (G1960-60648) doesn't appear to be working. We checked the voltage entering the power supply and it is reading accurately at ~207 volts. When plugged into the power supply we were expecting that the Power Supply On light would at least illuminate. Is this a correct assumption? Would we get at least this one LED if the unit was not broken as long as it has power? We plugged it into the wall directly with 240V and still get no illuminated LEDs. Is this enough to safely assume the power supply is bad? Looking at the side vents you can see an internal led light illuminated green. We checked the fuse inside the power supply and it is good, any advice is appreciated.
