CrystalSix Sensor Operating Manual 5 Place the compression spring (item #28) in the cavity surrounding the 0.25" diameter shaft of the carousel assembly. Install the Teflon washer (item #39) onto the.25" diameter shaft. 6 With the connector facing outward, pass the top plate (item #10) over the 0.25" diameter shaft of the carousel assembly (item #5) and the .125" diameter alignment pin. 7 Secure the top plate to the sensor body utilizing the three #4-40 screws (items #14 and 17). 8 Install the pawl and actuator stem assembly (item #24) into the bellows assembly (item #19) by threading the actuator stem into the mating hole located in the bore of the bellows assembly. Continue to thread the actuator stem until the shoulder of the actuator stem is approximately .035" away from the bellows assembly. This .035" distance specification is for reference only; the actuator stem position may have to be adjusted to obtain the desired condition, as illustrated in Figure 1-3 on page 1-6. 9 Fasten the bellows assembly to the top plate utilizing the two #4-40 x 1.125" long screws (item #20). Do not tighten the screws. Position the bellows assembly in such a fashion as to allow the actuator stem to come in contact with the ball bearings (item #25) as illustrated in Figure 1-3 on page 1-6. Tighten the screws. Loosen the #2 screw (item #42) which secures the detent to the bellow assembly (item #19). 10 Slide the ratchet (item #22) and the stop ratchet (item #38) onto the 0.25" diameter shaft of the carousel assembly (item #5) as illustrated. Do not tighten the #6-32 set screws (item #33). 11 Attach the loop of the extension spring in the hole provided in the pawl of the pawl and actuator stem assembly (item #24). 12 Position the ratchet (item #22) such that it engages the pin of the pawl and actuator stem assembly (item #24). 13 Position the detent (item #41) so it engages the ratchet (item #22). Unit is now ready to be aligned, refer to section 4.4.1 on page 4-4. IPN 074-155G 4 - 8
CrystalSix Sensor Operating Manual 4.5 Troubleshooting the CrystalSix Sensor Table 4-1 Troubleshooting Symptom Cause Remedy Crystal fail signal on front panel of unit will not disappear even though crystal can be seen through heat shield aperture. Damaged Crystal. Loss of electrical signal. Replace crystal. Check for electrical continuity betwen feedthrough and leaf srpings that make contact with the crystal holder in the sensor.* If electrical problem originates in the sensor, consult Chapter Chapter 4 for disassembly instructions, if necessary. IPN 074-155G Unit will not advance when crystal switch key is pressed. Crystal not centered in aperture. Loss of pneumatic supply, or pressure is insufficient for proper operation. Operation has been impaired as a result of peeling of the material accumulated on the face of the cover. Improper alignment. 0.025” diameter orifice not installed inline to the supply side of the solenoid valve assembly. Large jumps of thickness Mode hopping due to reading during deposition damaged crystal. * Make certain the leaf springs in the carousel assembly are bent up far enough to contact the crystal holder when installed. Establish air supply and regulate to 80-90 psi for operation. Consult Chapter Chapter 4 for disassembly instructions to remove material or to correct mechanical failure. Realign per alignment instructions in Chapter Chapter 4. Install orifice where shown on Figure 2-3 on page 2-8. Replace crystal. 4 - 9
