The instrument has been configured and calibrated to custom specifications. In-depth programming
of the instrument in the field should not be necessary.
Apply power to the instrument. Wait 10 minutes for the instrument to stabilize. During this period
the instrument may indicate a high flow condition. When the instrument is powered up, the
instrument will display an initialization sequence. Then the instrument will display the normal
operation information. Shown below is the normal operation window.
Caution:
FCI recommends placing an ON/OFF switch in line with the power source. When
JP1 is connected to the power source the instrument is ON.

Normal Operation Window
AC or DC power can be used to operate this instrument. For best results route the output signal
wiring through the left port of the instrument enclosure and the power input wiring thorough the
right port. See the wiring table on Page 16 to determine the minimum size of wiring to be used
versus the length of the wire run to the power source.
115 or 230 VAC Power Option
The input power can be switched from 115 Vac to 230 Vac by moving switch S1 to the correct
setting. (The instrument requires only AC or DC to be connected, not both.) Connect the hot side
of the AC Line to AC Line, the neutral side to AC NEUT, and ground to EARTH GND. (Do not
connect the local enclosure shield wire to the EARTH GND on this plug.)
24 VDC Power Option
If DC power is used, the AC Input and switch S1 are not pertinent. Wire the positive 24 volt input
to +24V. Connect the negative wire to DC GND.
