4. WIRING
4.1 Field Wiring
(1)Cables for field wiring
The following cables should be used unless otherwise specified.
Shielded chloroprene cabtyre cables (kind , JIS C 337, shielded) or shielded vinyl cabtyre
cables (JIS C 33, shielded) with a conductor area .5mm
.
3-conductor cables may be used to suit your specific application. Shielded end should be
grounded
at the ground terminal of the receiving instrument.
()Transmission length
With transmission cables conforming to JIS C 337 or C 33 conductor area .5mm
, the
maximum transmission length is typically one kilometer.
NOTE:
If it exceeds one kilometer, consult factory.
(3)Prevention of inductive interference
To minimize the possibility of stray current pickup, route the field wiring sufficiently away from other
power cables and power circuits.
CAUTION: Verify the validity of flowmeter (pulse generator) to receiving instrument
combination by their product No., instrument No., etc. before making wiring
connections.
NOTE : Also see the topic "WIRING" in the instruction
manual of the receiving instrument used.
