Inleiding

This guide will cover the removal and replacement of the analog PCB within the Newport e500. In order to perform this operation, a screwdriver and torque wrench will be required. Be sure to keep track of all cables as they will be reused on the replacement PCB. For some helpful tips, go to page 64 in the user manual.

  1. Newport e500 Analog PCB Disassembly, Newport e500 Top Cover Disassembly: stap 1, afbeelding 1 van 1
    • Place device so that the top cover is facing you.

    • Open the top cover.

  2. Newport e500 Analog PCB Disassembly: stap 2, afbeelding 1 van 1
    • Remove the four hex nuts and lock washers (two at each hinge) that secure the cover to the hinges on the left side of the pneumatic box.

  3. Newport e500 Analog PCB Disassembly: stap 3, afbeelding 1 van 1
    • Remove the cover and set aside. Retain hardware for re-assembly.

  4. Newport e500 Analog PCB Disassembly, Newport e500 Exhalation Module Disassembly: stap 4, afbeelding 1 van 1
    • Pull up and remove the flexible rubber exhalation outlet boot (push fit).

  5. Newport e500 Analog PCB Disassembly: stap 5, afbeelding 1 van 1
    • Disconnect the tubes from both sides of the flow sensor and the two tubes from the exhalation valve.

  6. Newport e500 Analog PCB Disassembly: stap 6, afbeelding 1 van 1
    • Pull the exhalation module straight up to remove it from the GDU.

  7. Newport e500 Analog PCB Disassembly, Newport e500 Air and Oxygen Flow Sensors Disassembly: stap 7, afbeelding 1 van 1
    • Remove the 2 screws and washers securing the manifold/mixer assembly

  8. Newport e500 Analog PCB Disassembly: stap 8, afbeelding 1 van 1
    • Slide the manifold/mixer assembly forward to disengage the flow sensors

  9. Newport e500 Analog PCB Disassembly: stap 9, afbeelding 1 van 1
    • Gently pull each flow sensor straight out from the servo valve, (the flow sensor push-fits into the servo valve port).

  10. Newport e500 Analog PCB Disassembly: stap 10, afbeelding 1 van 1
    • Disconnect the flow sensor cable from its 10 pin connector at the underside of the flow sensor PCB and lift out the flow sensor.

  11. Newport e500 Analog PCB Disassembly, Newport e500 Pneumatic Panel Disassembly: stap 11, afbeelding 1 van 1
    • Remove the screw and washer that secure the exhalation manifold support to the pneumatic panel.

  12. Newport e500 Analog PCB Disassembly: stap 12, afbeelding 1 van 1
    • Pull up on the exhalation valve guide block to remove it from the pneumatic box.

  13. Newport e500 Analog PCB Disassembly: stap 13, afbeelding 1 van 1
    • Remove the standoff and five screws and washers that secure the pneumatic panel to the pneumatic box.

  14. Newport e500 Analog PCB Disassembly: stap 14, afbeelding 1 van 1
    • Lift the pneumatic panel out of the box, and from the underside, detach all tubes and the heater wires that connect to the analog PCB.

  15. Newport e500 Analog PCB Disassembly, Newport e500 Analog PCB Disassembly: stap 15, afbeelding 1 van 1
    • Remove the cable from the connector J1 on the analog PCB.

  16. Newport e500 Analog PCB Disassembly: stap 16, afbeelding 1 van 1
    • Carefully pull the tubes from each of the seven transducers on the analog PCB. Take note of the tubing connections for re-assembly.

  17. Newport e500 Analog PCB Disassembly: stap 17, afbeelding 1 van 1
    • Disconnect the J4 connector from the analog PCB.

  18. Newport e500 Analog PCB Disassembly: stap 18, afbeelding 1 van 1
    • Remove the four screws and washers that hold the analog PCB to the pneumatic box assembly.

  19. Newport e500 Analog PCB Disassembly: stap 19, afbeelding 1 van 1
    • Hold tubing aside and remove analog PCB from the box assembly.

Conclusie

To reassemble your device, follow these instructions in reverse order.
