Turn ON the INSTRUMENTS power switch on the front, top left of the Control Cabinet.
The (2) PP3 pressure controllers and the RPM4 reference pressure monitor in the
Control Cabinet should initialize and go their main run screens. If they do not power up,
check from the rear of the Control Cabinet that their power cords are properly connected
and/or that the power switch on the power strip inside the Control Cabinet is ON.
Turn ON the UTILITY PUMP power switch on the front, top left of the Control Cabinet. If
the utility pump does not power up, check the power switch on the pump and turn it ON if
necessary.
If ADCS Tools software is currently ON, be sure the current measurement mode is
gauge. Turn ON the REFERENCE PUMPS power switch on the front, top left of the
