5. WIRING
5.1 Cables for Field Wiring
(
1
)
Use electrostatically-shielded, polyethylene-insulated, vinyl-sheathed control cables, or equivalent,
for input signal cables (CEVS 1.25-2.00mm
2
, 2-conductor). For signal cables, vinyl-insulated, vinyl-
sheathed cables (CVV, CVS, JIS C 3401) are recommended.
(

)
Ground the cable shielding to terminal "G" of the instrument. All circuitry on the detector side must
be "floated" from ground.
CAUTION
Make electrical connections upon
confirmation of valid combinations
of flowmeter (pulse generator) and
receiving instrument by their model
No., serial No., etc.

(

)
Separate field wiring from other power lines and power circuits to minimize the possibility of
inductive interference.
(

)
Using crimp-style terminals for wiring connections, ensure good electrical connections. Terminals
are found on the back of the computer.
(

)
Good practice is to provide an allowance of 30 centimeters approx. to the wirings to facilitate
internal assembly withdrawal during servicing.
5.2 Wiring Connections
(
1
)
Conduit work is recommended for field wiring.
NOTE: In conduit work, use separate conduit for power cable and signal cables to eliminate the
possibility of stray current pickup.
