GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL Chapter 5 - Components and Functions (Theory) 5 - 129 5-11-2 AC Controller 5-11-2-1 General Description of the AC Controller The AC Controller’s main task is to supply the va rious internal subsystems with AC power and to galvanically isolate the scanner from the on-site Mains Power System. An inrush current limiter reduce the peek input current when the unit is switched on. An EMI filter helps to reduce EMI to acceptable levels. The voltage to peripherals can be configured to either 115 VAC or 230 VAC. The AC Power also controls and supplies the 20VAC ne eded by the systems cooling fan. The mains cord has plugs in both ends. A female plug connects to the scanner and a male plug to the wall mains outlet. The mains voltage is routed from the mains power inlet at the rear of the system via an EMI filter to the Mains Circuit Breaker, also located at the rear of the system. From the Mains Circuit Breaker, the AC power is routed via an Inrush Current Limiter (titled: Inrush Limiter in Figure 5-82) to an internal outlet connector for the AC Transformer. The Mains Circuit Breaker is of the auto fuse type. If for some reason the current grows to high, the switch will automatica lly break the power.Figure 5-82 AC Power Distribution AC INLET BOXTO OUTLET M INRUSH LIMIT Mains switch 230Vac 115Vac 230Vac 20Vac 23011 5 Fanregulator L TRANSFORMER BOX TO PERIPHERIALS (115 or 230 Vac) TO MONITOR (115 Vac) TO MODEM (230 Vac) TO PC (230 Vac) TO CARD RACK (230 Vac) Cable #27 Cable #7TO A14 ON INTERNAL I/OPOWER SUPPLY ON, FAN SPEED CONTROL CABLES INTERNAL IN AC CONTROL MODULE Cable #28 AC DISTRIBUTION PWB Cable #31-2 Cable #13-2Cable #31-3 Cable #31-1 Cable #30 Cable #31-4 FAN ASSEMBLY COMPLETE
GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL 5 - 130 Section 5-11 - Power Distribution 5-11-2-2 The AC Transformer The AC Transformer is the galvanic barrier between the rest of the scanner and the on-site AC Mains. Input voltage to the transformer can be either 2 30 VAC or 115 VAC. The transformer has two 115 VAC primary windings which are series- or parallel coupled depending on input voltage (see Figure 5-83). Each of the primary windings has one thermal protection device in series with the windings, which will open if internal temperature exceeds 125 oC. The plug on the cable to the AC Transformer is po sitioned different for the two AC Mains voltages, see Figure 5-84 Connector Pin-out - AC Connectors on AC Controller on page 5-131 . The secondary side of the transformer has two 11 5 VAC windings and one 20 VAC winding. The two 115 VAC windings are connected in series to produc e 230 VAC, so the following voltages are available on the plug from the AC Transformer: • 230 VAC • 115 VAC • 20 VAC Figure 5-83 115VAC/230VAC Input Voltage Selection PLUG IN 115 VAC POSITION 115 VAC MAINSPLUG IN 230 VAC POSITION 230 VAC MAINS TRAFO TRAFO

Both 115 VAC and 230 VAC are routed via fuses. • 115 VAC is routed to th e Monitor outlet (MONITOR) • An AC Voltage selector is used to select the correct voltage for the Peripherals. The selected voltage (230 VAC or 115 VAC) is routed to the Peripherals AC outlet (PERIPH’S) • 230 VAC is distributed to; - Modem AC outlet (MODEM) - Back-End Processor AC outlet (PC) - Front End Card Cage AC outlet (RACK) Figure 5-84 Connector Pin-out - AC Connectors on AC Controller
