The IOX replaces the CI board and the new iPDB replaces the PDI board on the rear of the chassis. The power supply units are re-located to the back of the electrical chassis. 09/11/2020 12 23 Electrical Chassis Comparison As mentioned before, the power supply units were re-located to the back of the chassis, but now there is only a 12VDC and 24VDC. The X-ray Generation components have been replaced by a 12VDC and 48VDC PSU, and are now on the chassis as opposed to being on-board the PDI board. 5 600XRhp Series: System Components 09/11/2020 13 25 600XRhp Series Components Now that we have looked at the basic structure of the XRhp sub-systems, lets take a closer look at each of the components. 26 600XRhp Series Components We will discuss the following components starting from power coming into the system. •Power Distribution including; • Main Circuit Breaker. • In-Rush PCB • Transformer and Terminal Block assembly. •IPDB (integrated Power Distribution Board) •PSU’s (Power Supply Units) •IOX (Input-Output Extension) •Junction Board and Photo Sensors •Concentrator board •DAB’s (Diode Array Boards) •X-ray PSU •XRC (X-ray Controller) •Inverter •Lamps, ICP & LVDS •Error Messages 09/11/2020 14 27 600XRhp Series Components POWER DISTRIBUTION & iPDB 28 - Proprietary - Power Distribution Overview 09/11/2020 15 29 600XRhp Series Components The Main Circuit Breaker (MCB) is located by the main power receptacle. The system uses a 16A circuit breaker that is used to interrupt the power in to the system. The MCB from the inside of the system. 30 600XRhp Series Components The transformer is responsible for transferring power from the wall to the system without a physical connection. In this configuration, the transformer is used both as an isolation device as well as a step-up transformer (when required). 09/11/2020 16 31 600XRhp Series Components The function of the in-rush suppressor is to reduce the surge of current on power up and prevent nuisance tripping of the circuit breakers. The inrush suppressor contains two thermistors in-line with the primary side of the main transformer. 6A Fuses on terminal block. The thermistors remain cool since they are bypassed after power up. 32 - Proprietary - Power Distribution Sequence iPDB acts as an interface between the: Rollers Power-on switch, key-switch Interlocks, E-stops, and Indicator lamps. The iPDB distributes AC voltage to the following components: PSU’s and X-ray power supply UPS and Computer Inverters 09/11/2020 17 33 System Fuses and Location 34 600XRhp Series Components The iPDB distributes AC/DC power to various components. It handles AC distribution to components such as the UPS, power supply units, inverter, generator fan, X-ray transformer, computer, and the power strip. With a number of useful indicators and test points, the IPDB is the first area to observe when checking system malfunctions. 09/11/2020 18 35 600XRhp Series Components The iPDB also send DC voltage to the power-on and key-switches, the system fans, and the PC power on pulse. The iPDB is also responsible for monitoring the safety circuits such as the inverter status, emergency stops, interlocks, trip trays and the operator sensor. 36 600XRhp Series Components 24VDC 620XRhp 12VDC 12VDC 24VDC The iPDB feeds the PSU’s which generate the DC voltages used by most components on the system. •PSU1 24VDC: Feeds iPDB •PSU2 12VDC: Feeds IOX and Concentrator 618XRhp 09/11/2020 19 37 IOX BOARD 38 IOX Board The Input and Output Extension (IOX) provides an interface between the data acquisition system and the rest of the peripheral hardware. The IOX controls indicator lights, search buzzer, Inverters and the XRC board. The IOX also monitors: •System fans and heaters •Position sensors •Interlocks •E-stops •Trip trays •Operator sensors •Drive roller status The IOX functions with 12VDC from PSU2 09/11/2020 20 39 Lets take a look at the connectors that are used in this board. 2x 12VDC inputs from PSU2. IOX Board 40 Just like the iPDB, the IOX has many indicator LEDs that will help in diagnosing a system fault.
