Omega FD6003 - Manual (Page 23)

3-7
Note: The FD6000 Series flow meter system requires a
full pipe of flowing liquid before a successful startup can
be completed. Do not attempt to make adjustments or
change configurations until a full pipe is verified.
Procedure:
1. Verify that all wiring is properly connected and routed.
2. Apply power.
3. Adjust the GAIN control [R13] to 1/4 turn from full
counter-clockwise rotation.
4. Apply power to the instrument.
5. If the pipe is full of a flowing liquid that contains ade-
quate concentrations of suspended solids, the flow me-
ter signal strength will increase from a zero reading.
(press the 2nd FUNCT key, then press SIGNAL STR).
If the Signal Strength does not increase to a minimum
of 000125 counts, gradually turn the GAIN control
[R13] clockwise until the indication is at between
000125 and 000200. (Do not over adjust this setting
as ambient noise can influence readings.)
6. If possible, turn off the flow in the pipe. Verify that
SIGNAL STR. is lower than 000100. If SIGNAL STR.
is greater than 000100, verify that the sensor/
transmitter are not located near electrically noisy
components. (VFDs, inverters, motors, power relays,
etc) Verify that DT6 transducer connections are proper
and secure. If the SIGNAL STR. remains greater than
000100,
consult OMEGA Engineering for
assistance. It is possible that the GAIN control [R13] is
set too far clockwise and ambient noise is influencing
the readings. Turn the control counter-clockwise until
the signal strength decreases to below 000070 counts.
5. If the instrument passes steps 5 and 6, the basic setup
of the instrument is complete.
PART 3 - STARTUP AND CONFIGURATION
Before Starting the
Instrument
Important!
Instrument Startup
It is normal to have low/zero SIGNAL STRENGTH
indication at ZERO flow.
