WARNING
VY### vortex owmeter (Integral Flowmeter
and Remote Sensor), and VY4A Remote
Transmitter are products which have been
certied as explosion protection type products if
model code for explosion protection is specied.
Strict limitations are applied to the structures,
installation locations, external wiring work,
maintenance and repairs, etc. of these products.
Su󰀩cient care must be taken, as any violation of
the limitations may cause dangerous situations.
Be sure to read this manual before handling the
explosion protection type products.
WARNING
If the terminal box cover and display cover are
locked by hexagon socket head cap screw, in the
case of opening the cover, use the hexagonal
wrench (nominal size 3).
Read the Maintenance Manual, IM 01F07A01-
02EN, for the procedure.
Before opening the cover, be sure to check that
the power of owmeter has been turned o󰀨.
Once the cover is closed, be sure to re-lock the
product.
Be sure to lock the cover with the screw by using
the hexagonal wrench after tightening the cover.
IMPORTANT
For multiple approval types:
For the installation, once a particular type of
protection is selected, any other type of
protection cannot be used. Apply a permanent
mark in the check box of the selected approval
type on the certication label to distinguish it from
unused approval types as follows;
e.g.)
