For Vortex Flow Converter (Dya) - YOKOGAWA DY025 User Manual

3.6.2 For Vortex Flow Converter (DYA)

1 Strip off the outer polyethylene jacket, outer braided
shield and inner jacket, and inner braided shield as
per the dimensions as shown.
2 Cut of the black conductive layers(convering the
two wires) completely, as per the dimensions below.
Twist each of the conductor and drain wires so that
there are no free strands.
3 Do not short-circuit the conductive layer and the
terminals (A, B, C, G and T).
4 Strip off about 5 mm (0.2 in.) of insulation for each
of wires A, B, and T, and twist the strands of each
wire.
5 Slide black FEP (fluorinated ethylene propylene)
tubing over the inner shield drain wire C and blue
FEP tubing over outer shield drain wire G until
the tubing cannot be slid any further, and then cut
off the tubing leaving 5 mm (0.2 in.) of the drain
wires exposed.
6 Slide heat shrinkable tubing over the cable end so
that the tubing covers the braided shield and
overlaps both the polyethylene jacket and loose
wires A, B, C, G, and T.
7 Slide a short piece of heat shrinkable tubing over
each of wires A, B, C, G, and T. Install a crimp-on
terminal lug at the tip of each wire. Crimp and
solder each lug.
8 Slide each short piece of heat
shrinkable tubing over the crimp sleeve. Heat all
pieces of heat shrinkable tubing with a heat blower
or dryer.
9 Attach an identification label to the end of the cable.
NOTE
Check that the insulation resistance between each
wire including the inner shield is 10MΩ or greater at
500V DC. Ensure that both ends of the wires are
disconnected (open-circuited) during the check.

Do not touch the '' conductive layer"
(black area covering the signal cables A
and B) to the converter case, terminal,
and other leadwires. If it is touched,
operation of the converter may be
incorrect. When the cable is terminated,
remove the conductive layer properly.
