MI 019-100 – December 2003 2. Installation Table 6. JCFS10 or CFS20 (Style B) Junction Box Wiring Wire Color Black Green Red Black Black, Shield Yellow Black Brown Black White Signal RTD Sensor B Sensor A Driver 2 Driver 1 Signal Cable Preparation If conduit is to be used, run the unprepared end of the cable through the conduit from the transmitter. Flowtube End 1. Cut the flowtube end of the cable to length and strip back the jacket approximately 127 mm (4 in). 2. Separate the twisted pair conductors from their wrappers, shields, and drain wires. The wire pairs should remain twisted for ease of identification. 3. Trim the shields, wrappers, and drain wires back to the jacket interface. 4. Strip the ends of the conductors 6 mm (1/4 in). Transmitter End (Customer Supplied Cable) Follow Steps 1, 2, and 4 above. Trim shields and wrappers back to the jacket interface. Tightly twist together (2 to 4 turns) the six individual twisted pair drain wires at a point close to the jacket interface. Trim all but one drain wire close to the twist. Solder the twisted wire area, creating a single drain wire. Appropriately insulate the drain wire and soldered connection to prevent shorting. Refer to MI 019-132 for CFT50 wiring instructions. CFT50 Transmitter Installation Mounting The CFT50 Transmitter remotely mounted housing is supported by a mounting bracket which can be attached to a surface or nominal DN 80 or 3-in vertical pipe. Mount the bracket to a surface using four (user supplied) 0.375 inch or M10 bolts or to a pipe using the two U-bolts (included). See Figure 7. 16
2. Installation MI 019-100 – December 2003 HOUSING BRACKET BOLT SCREWS (4) CONNECTOR MOUNTING BRACKET SURFACE MOUNTING PIPE MOUNTING Positioning the Housing Figure 7. Transmitter Mounting The housing can be positioned at almost any angle in a horizontal plane by using one or both of two procedures. First, the housing can be rotated up to 270° in either direction in 90° increments by removing the four screws securing the housing to the connector. Second, the housing can be rotated by loosening the bracket bolt and turning the housing with respect to the mounting bracket. See Figure 7. Wiring Field Wiring To access the transmitter field terminals, remove the field terminal compartment cover by turning it counter-clockwise using the cover tool provided. The field terminal compartment cover is the one closest to the conduit openings. When replacing the cover, tighten until the cover meets the housing metal-to-metal. 17
