X2 Check Power Supply
1. Retighten the power input and 24v supply on the power supply.
2. Unplug the power supply input on the PCB and connect the voltage tester.
Plug in the unit and check voltage between blue and blue/white. You should have 24v DC. If there is
not 24v, the power supply unit needs to be replaced.
