Model GF92 Flowmeter 6 Doc. No. 06EN003321 Rev.-
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.
Step 5. Operation
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.
Wiring the Input Power:
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 through the right port. See the wiring table on Page 4 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.
