INSTALLATION AND MAINTENANCE INSTRUCTIONS
Intrinsically safe/low power solenoid operator (WP/WSIS-M12-I NVR)
GENERAL
This installation and maintenance
instruction sheet of the solenoid is a general
supplement to the particular I&M sheet for
the valve. The identification is made by prefix
IS to the catalogue number. Always use both
I&M sheets for installing and maintaining the
solenoid valve.
DESCRIPTION
The solenoid valves are designed in accord-
ance with Annex II of the European Directive
94/9/EC or 2014/34/EU and IECEx Scheme:
IECEx 02. EC type examination certificate
KEMA 98ATEX2544X and IECEx certificate
IECEx KEM08.0017X are in compliance
with International and European standards:
ATEX IECEx
EN 60079-0 : 2012 IEC 60079-0 : 2011
EN 60079-11 : 2012 IEC 60079-11 : 2011
EN 60079-26 : 2007 IEC 60079-26 : 2006
EN 13463-1 : 2009 IEC 60529 : 2001
Classification:
II 2G Ex ia IIC Gb / II 2D Ex ib IIIC Db IP67
INSTALLATION
ASCO components are intended to be used
only within the technical characteristics as
specified on the nameplate. Changes to the
equipment are only allowed after consulting
the manufacturer or its representative. These
solenoid valves are intended for installation
in potentially explosive atmospheres,
Groups II A, II B or II C gases, vapors,
mists or dusts (Group II, category 2G/2D).
The surface temperature classification is
T6/85°C.
ELECTRICAL INSTALLATION
Wiring must comply with local and national
regulations of explosion proof equipment.
Application of the IS solenoid in the
hazardous area is not permitted without
the addition of an approved and classified
device (such as barriers), located between
the safe and the hazardous area. The
purpose of the safety device is to protect
the equipment located within the hazardous
area from current and voltage surges,
which might enter the system from the
energy sources located in the safe area.
In addition the wiring to the equipment
installed within the hazardous location
should satisfy particular requirements with
respect to resistance (R), inductance (L),
capacitance (C), inductance to resistance
ratio (L/R) and screening.Due to redundant
blocking diodes the effective internal
inductance and capacitance of the solenoid
are neglibly small.To make connection to the
coil terminals, remove solenoid cover. Strip
the outer insulation of the cable over approx.
30 mm and the insulation from the leads
over 8 mm.Insert wires through the cable
gland or conduit hub and connect wires
to the terminals of the coil. Connect cable
ground wire to the internal ground terminal.
Keep some slack in the leads between cable
entry and coil to avoid excessive strain on
the leads. Assemble the cable gland and
tighten the elastomer compression seal
so that it fits tightly around the cable. The
solenoid can be rotated 360° to select the
most favorable position for the cable entry.
The solenoid housing is provided with an
external connection facility for an earthing
or bonding conductor.
NOTE: THE STANDARD CABLE GLAND
ACCEPTS CABLES WITH OVERALL O.D.
from 7 to 12 mm.
ELECTRICAL SPECIFICATIONS
Minimum operating current 25mA.
Intrinsically Safe Coil Calculations
The following application information will
allow the calculation of the loop current for
the ASCO intrinsically safe solenoid.
Definitions:
Vsupply The supply voltage to the
barrier.
Tambient The ambient temperature in
degrees C.
Rbarrier The maximum barrier end to
end resistance.
Rloop The maximum resistance in
lead wire
Rcoil The resistance of the solenoid
coil at Tambient
Rcoil = 406

This current must always be greater than
or equal to 25mA for proper operation fo
the solenoid valve. The minimum supply
voltage applied to input terminals of the
barrier to reach the minimum 25mA can be
calculated as follows:
Vsupply min. = (20 + Rcoil + Rloop + Rbarrier)
0,025 + 1,4
CAUTION
Electrical load must be within the range
stated on the nameplate. Failure to stay
within the electrical range of the coil rating
results in damage to or premature failure of
the coil. It will also invalidate the approval.
If the solenoid is used in a gas and/or
dust environment, the risk of electrostatic
discharge shall be avoided.
SERVICE
To prevent the possibility of personal or
property damage, do not touch the solenoid.
It can become hot under normal operation
conditions. If the solenoid valve is easily
accessible, the installer must provide
protection preventing accidental contact.
MAINTENANCE
Maintenance depends on service conditions.
Periodic cleaning is recommended, the
timing of which will depend on the media
and service conditions. During servicing,
components should be examined for
excessive wear. A complete set of internal
parts is available as a spare parts kit.
If a problem occurs during installation/
maintenance or in case of doubt please
contact ASCO or authorized representative.
CAUTION: Before servicing the solenoid
valve, turn off electrical power, depressurize
valve and vent fluid to a safe area. Solenoid
must be fully reassembled as the housing
and internal parts complete the magnetic
circuit. In case of any replacement of parts
by the user, the traceability of the final
product can not be guaranteed by ASCO.
Wrong assembly will invalidate the approval.
