Mobile Digital C-Arm Service Manual - Periodic Maintenance
Inspect/Adjust the C-Arm Power Supply Voltages (PS2)
WARNING:
Electrical circuits inside the equipment use voltages that are capable of causing serious injury
or death from electrical shock. Use appropriate precautions.
1. Refer to the PROCEDURES section of the service manual (00-878315) for accessing the 6600
Controller PCB. Refer to the Power Distribution section in the service manual (00-878315) for
the location of PS2.
2. PS2 output voltages are adjusted using the voltage adjustment pot shown in FIGURE 3. Power
supply voltages are measured on the 6600 Controller PCB at the test points listed below:
- Lead + Lead Supply Tolerance Reading Range
TP2 TP42 +24.0 VDC +10%/-5% +22.8 to +26.4 VDC
TP2 TP37 +12.0 VDC ±3% +11.6 to +12.4 VDC
TP2 TP23 +5.0 VDC ±2% +4.9 to +5.1 VDC (VCC)
TP2 TP39 +5.00 VDC ±2% +4.9 to +5.1 VDC (+5.00 V Ref)
TP2 TP43 -10.00 VDC ±2% -9.8 to -10.2 VDC (-10.00 V Ref)
TP2 TP44 -12.0 VDC ±3% -11.6 to -12.4 VDC
TABLE 4
NOTE:
The 6600 Controller PCB contains a circuit breaker (CB1) to protect the +24 volt supply to the
monoblock X-ray source.
