*Note: Requires a shielded cable. The shield is connected to the GND pin of TS_ of the input board. The
other end of the shield is left floating (no connection to the flow element enclosure).
The standard cable provided is 22 AWG. Refer to
, page 35, for specific information.
Flow Transmitter Wiring Connections
, page 7, for the flow element wiring to the input boards. Run separate excitation and sense
wires for the Active, Reference, and Ground connections. The flow meter will not operate properly without these connections. If the Active
and Reference wires are reversed the flow meter will output incorrect flow rates. Use shielded cable with all signal applications. Connect
the shield to the input board only and not to the flow element terminal strip. Connect the shield to pin 1 of TS_ on the input board.
The connector for sensing point 1 must be plugged into the innermost connector on the input board which is plugged into P1 of the control
board. Sensing point 2 is connected to the outermost connector of the same input board. Sensing point 3 is plugged into the innermost
connector on the input board which is plugged into P2 of the control board. Sensing points 4 through 8 are plugged in the same manner.
Make the customer connections to the output modules (relay logic, current or voltage).
