FLUID COMPONENTS INTL INSTALLATION, OPERATION AND TROUBLESHOOTING GUIDE
Wiring the Remote Instrument (Option):
Install a shielded, 8 wire cable between the remote
enclosure and the local enclosure as shown.
The Shield wire and the Heater Return wire must
be connected together and inserted into the connector.
The connector is plugged into the connector (TS2)
at the top of the board as shown. Use the schematic
representations of the mechanical assemblies as a wiring
guide.

Wiring the Input Power:
Caution:
FCI recommends placing an ON/OFF switch in line with the power source. When TS1 or TS4 is
connected to the power source, the instrument is ON.
AC or DC power (not both) can be used to operate this instrument. For best results route the output signal wiring through the
opposite port from the power input wiring. See the wiring table on the previous page to determine the size of wiring to be used
versus the length of the wire run to the power source.
