WARNING
VY### vortex owmeter (Integral Flowmeter or
Remote Sensor), and VY4A Remote Transmitter
are products which have been certied as
explosion protection type products.
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 special 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 special screw
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.)

In case Nonincendive Field Wiring Concept is used for the interconnection, Associated
Nonincendive Field Wiring Apparatus, which meets the following conditions, must be sed as the
Power Supply / Control Equipment. When more than one Nonincendive Field Wiring Apparatus
are connected in a Nonincendive Field Wiring circuit, total Ci and Li of the connected apparatus
must be considered.

2.4 Operation
• Take care the following warning marking.
“POTENTIAL ELECTROSTATIC CHARGING HAZ-
ARD.”
“DANGER POTENTIEL DE CHARGES ÉLECTRO-
STATIQUES.”
Integral Flowmeter
Explosionproof (Certication Code: CF1)
• Take care the following warning marking.
“AFTER DE-ENERGIZING, DELAY 3 MINUTES
BEFORE OPENING.”
“APRÈS MISE HORS TENSION, ATTENDRE 3 MIN-
UTES AVANT L'OUVERTURE.”
Remote Transmitter
Explosionproof (Certication Code: CF1)
• Take care the following warning marking.
“AFTER DE-ENERGIZING, DELAY 3 MINUTES
BEFORE OPENING.”
“APRÈS MISE HORS TENSION, ATTENDRE 3 MIN-
UTES AVANT L'OUVERTURE.”
2.5 Maintenance and Repair
• A modication of the equipment would no
longer comply with the construction described
in the certicate documentation.
• Only personnel authorized by Yokogawa
Electric Corporation can repair the equipment
2.6 Specic Condition of Use
• Electrostatic charges on the non-metallic parts
(excluding glass parts) or coated parts of the
equipment shall be avoided.
• Read Section 2.1 for details of temperature
ratings.
Integral Flowmeter
Explosionproof (Certication Code: CF1)
• Explosionproof joints are not intended to be
repaired. Contact Yokogawa representative or
Yokogawa o󰀩ce.
• If the equipment is used as Um = 60 V DC, it
must be installed in a SELV (safety extra-low
voltage) or PELV (protective extra-low voltage)
system, or it must be directly connected to
apparatus complying with CAN/CSA-C22.2 No.
61010-1 or a technically equivalent standard.
• The equipment shall be installed as overvoltage
category I.
Intrinsically Safe (Certication Code: CS1,
Communication and I/O Code: JA or JB)
• When the equipment is mounted in Zone 0, it
shall be installed in such a way that, even in the
event of rare incidents, an ignition source due to
impact and/or friction sparks is excluded.
• The dielectric strength of 500 V r.m.s. between
the intrinsically safe circuit and the enclosure of
the equipment is limited, only by the removable
surge absorber.
Remote Sensor
• When the equipment is mounted in Zone 0, it
shall be installed in such a way that, even in the
event of rare incidents, an ignition source due to
impact and/or friction sparks is excluded.
• From the safety point of view, the intrinsically
safe circuit of the remote sensor shall be
assumed to be connected to earth.
Remote Transmitter
Explosionproof (Certication Code: CF1)
• Explosionproof joints are not intended to be
repaired. Contact Yokogawa representative or
Yokogawa o󰀩ce.
• If the equipment is used as Um = 60 V DC, it
must be installed in a SELV (safety extra-low
voltage) or PELV (protective extra-low voltage)
system, or it must be directly connected to
apparatus complying with CAN/CSA-C22.2 No.
61010-1 or a technically equivalent standard.
• The equipment shall be installed as overvoltage
category I.
Intrinsically Safe (Certication Code: CS1,
Communication and I/O Code: JA or JB)
• When the equipment is mounted in Zone 0, it
shall be installed in such a way that, even in the
event of rare incidents, an ignition source due to
impact and/or friction sparks is excluded.
• The dielectric strength of 500 V r.m.s. between
the intrinsically safe circuit of the remote
transmitter without the option code /BWC and
the enclosure of the equipment is limited, only
by the removable surge absorber.
2.7 Primary Seal Failure
Annunciation
If the Primary Seal fails, Process uid leaks out
from the Hole of BRACKET by Stopper out.
This leakage is noticed visibly or audibly and
decreasing pressure by venting uid.
