1-2 This manual contains detailed operating instructions for all aspects of the FD6000 instruments. The following condensed instructions are provided to assist the operator in getting the instrument started up and running as quickly a s possible. This pertains to basic operation only.
1-3 3. TRANSDUCER/PO WER CONNECTIONS A. Do not attempt to add additional cable to the transducers. B. Refer to the DIAGRAMS in Figure 1.2 for proper pow er and transducer connections. Verify proper jumper selections are in place for the pow er source.
1-4 The FD6000 Series flowmeter is designed to measure the flow of liquids and slurries in full-pipe closed systems. The transmitt er is field con figured to measure flow on a variety of pipes and liquids. The standard product is typically used on pipe sizes ranging from 1 - 120 inch [ 25 - 15 24 mm ] pipe I.
1-5 The flowme ter is typi cally used as a unidi rectional meter and is most ac curate when th e trans ducer is mounted in t he orient ation det ailed in this man ual. But, the met er w ill measure flow in both directions — although flo w direction will not be indicated or totalized properly.
1-6 The FD6000 Series employs modular construction and provides electrical safety for the operator. The display face c ontains voltages no g reater th an 9 Vdc and any ex posed met al work is electrically connected to Earth Grou nd.

Connect the load to the 4- 20 mA connecti on terminals located on the inside of the enclosure, matching polarity as indicated.
3-6 1. Guide the transduc er terminations thro ugh the transmitter cond uit hol e located on t he left s ide of t he enclosure. Secure t he transduc er cable w ith the supplied conduit nut. 2. The terminals o n the t ransducer ca ble are c oded w ith wire markings.
3-7 Note: The FD6000 Series flow meter system requires a full pipe of flowing liquid before a successful startup can be completed. Do not attempt to make adjustments or change configurations until a full pipe is verified. Procedure: 1. Verify that all w iring is properly connec ted and rout ed.
3-8 After a success ful flow meter installation and startup (covered in the previous sections of this manual) the FD6000 can be keypad c onfigured to prov ide select eng ineerin g unit readings of flow and a scaled 4-20mA output.
