3. ELECTRICAL CONNECTIONS Route 12-30 volt DC power
and earth ground through one of the FUSION conduit
connections and secure at the 12-30 VDC In, Power Gnd and
Earth Gnd terminals. Ensure that electrical codes applicable to
the installation area are followed. An installation drawing
covering Hazardous Area installations is located in the back of
this manual. (The FUSION meter contains several output
options that will be covered in detail in subsequent sections of
this manual.)
4. APPLY POWER After power is applied to the FUSION flow
meter, the display will illuminate and show the software
version that is running inside of the flow meter as Ux.xx. The
flow meter will then conduct self-diagnostic, measurement
and buffering operations during an Auto Adjust countdown
that is shown on the display. These operations are also
conducted each time a user exits from the keypad
configuration menu.
5. OPERATION If the flow meter is started empty, the display
will indicate “EMPTY PIPE” until the flow meter fills with liquid.
If the flow meter is filled with liquid, the flow meter will
display either DOPPLER or TRANSIT (indicating the mode of
operation that is supplying the flow readings to the display
and outputs).
6. CONFIGURATION There are seven parameters that are
configured in the field on a typical installation.
A. RATE UNIT
B. TOTAL UNIT
C. FLOW DIRECTION
D. OUTPUT <4-20 mA, PULSE>
E. FULL FLOW
F. FLOW CUTOFF
G. RESPONSE
7. TOTALIZER RESET The flow totalizer can be reset to zero
by simultaneously pressing the MENU and ENTER keys or by
momentarily connecting the Reset Total In terminal to Power
Gnd terminal.
