For remote instruments only: The flow element wires should be routed through the 3/4 inch NPT port for the
flow element as shown in Figure 2-3. Connect the flow element wires to TS2 on the electronics assembly
according to Figure 2-5. Connect the cable shield to HTR RTN. Leave the other end of the shield floating.
A 14 AWG ground wire should also be routed between the enclosures (wire terminals are supplied in the kit).
Note:
Connecting the shield in any other way will decrease the accuracy of the instrument. See Figure 2-4
for the wiring diagram.
Caution:
Be sure an earth ground wire is connected to the ground terminal (see Figure 2-4). On a remote
configuration, connect an earth ground wire to the ground screw in the local enclosure. This is for
the purpose of safety.
10. If a wire comes loose from the instrument during installation, refer to Chapter 5 - Troubleshooting for a
complete instrument wiring diagram.
