AC Power Supply

The gantry power supply is located in the lower left corner in the rear of the table console. It
powers the entire system except for the processing station. The outputs are divided into two
groups:
•
One group of continuous outputs (see Table 3.1 on page 3-7)
•
One group of safety interrupted outputs (see Table 3.2 on page 3-7).
All low voltage outputs are protected by PTC fuses.
Note. To reset the PTC fuses, all loads on the affected output must be removed; power must be
removed momentarily and then reapplied. Any capacitance within the circuitry will cause the fuse
not to reset. These fuses are not accessible and are not field-replaceable. Should one of these fuses
fail, the entire power supply must be replaced.
