CrystalSix Sensor Operating Manual 5 Tighten the feedthrough nut. 6 Add the air fitting to the tube which has the female thread adapter installed. 7 Connect the 1/8" Teflon air tube from the valve to the just installed fitting. CAUTION Use of more than 80" (2 meters) of 1/8" tubing between the valve and the bellows may cause switcher failure because of the time required to bleed out sufficient air during de-pressurization. If tubing greater than 1/8" is used, the maximum length must be reduced proportional to the additional volume. 8 Attach the valve’s intake (normally closed (NC) port) to the 80-90 psi source of air. Verifiy that the orifice (IPN 059-189) has been installed into this NC valve port. (See Figure 2 of Figure 3-2 on page 3-4.) 3.2 Installation with 2 3/4” Feedthrough Installation of the shutter control valve requires a 2 3/4" feedthrough inclusive of two coaxial feedthroughs (IPN 002-080, see Figure 5-2 on page 5-2). The second coaxial feedthrough is not used, and should be protected from damage as a result of process material. Follow the steps below: 1 Install the Feedthrough. 2 Add the valve bracket (modified) to the desired location as illustrated in Figure 3-3 on page 3-5. 3 Tighten the feedthrough bolts. 4 Install the air fitting to the female thread adapter. 5 Connect the 1/8" Teflon air tube from the valve outlet to the feedthrough fitting. See the CAUTION in section 3.1 above. 6 Attach the valve’s intake (normally closed (NC) port) to the 80-90 psi source of air. Verify that the orifice (IPN 059-189) has been installed into this NC valve port. (See Figure 2 of Figure 3-2 on page 3-4.) NOTE: Maximum temperature for the shutter control valve assembly is 105 °C for bakeout and operation. IPN 074-155G 3 - 2
3.3 Electrical and Pneumatic Connections 3.3.1 Electrical CrystalSix Sensor Operating Manual To complete installation of the assembly, make electrical connections to Pins A and C for either 25 V(ac) or V(dc). (See Figure 3-1.) Current required is approximately 70 mA.
