IMPORTANT
■ When wiring ULTRA YEWFLO, avoid locating it near such sources of noise as
transformers, motors or electromotive power supplies with large current capacities.
■ Remove the terminal cover and dust-prevention plug on the wiring port before wiring
ULTRA YEWFLO.
■ ALWAYS waterproof all threaded parts. (A silicon-resin, non-hardening sealing
material is recommended for the waterproof treatment.)
■ To protect against noise, do not allow the signal cable and electromotive cables to
run through the same duct.
■ Explosion-proof models of ULTRA YEWFLO must be wired in compliance with
applicable regulations to ensure explosion-proof performance.
Refer to “Installation and Operating Precautions for Flameproof Instruments” at the
end of this manual to wire ULTRA YEWFLO correctly.
5.1 Selecting the Cable
Observe the following precautions when choosing cables for use with the transmission
loop line.
■ Use a twisted cable equal to or better than 600V grade polyvinyl chloride insulated
wiring (JIS C3307).
■ When wiring ULTRA YEWFLO in an area susceptible to noise, use a shielded cable.
If ULTRA YEWFLO will be used in a simultaneous analog-pulse output mode,
separately shielded two-wire cables may become necessary. (See Section 5.5 for
more information.)
■ When wiring ULTRA YEWFLO in an area where the ambient temperature is
comparatively high or low, use a cable suited for the place of use.
■ When using ULTRA YEWFLO in an area where a harmful gas, liquid, oil and/or
solvent is present, use a cable resistant to these substances.
■ Crimp-on terminals (for 4-mm screws) with insulated sleeves are recommended as
the cable-end configuration.
CAUTION
For the remote type, using UYF021 signal cable to connect the converter and remote
type flowmeter.
