INSTALLATION AND MAINTENANCE INSTRUCTIONS
Low power, intrinsically safe solenoid operator (ISSC – 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 IP65
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
the electrical connection to the spade
plug connector, strip the outer insulation
of the cable back over approximately 30
mm and the insulation from the leads
over 5 mm. Select the proper sealing ring
Ø 6-8 mm or Ø 8-10 mm depending on
cable diameter. Insert cable through the
compression screw, washer, sealing ring
and connector housing and connect wires
to the terminal block. Place terminal block
into connector housing and assemble
connector cover. Note that the cover must
be pressed properly to the connector until
a ‘click’ is heard. The terminal block can be
mounted in four different positions to select
the most favourable position for the cable
entry. Assemble the sealing ring, washer
and tighten the compression screw into the
connector housing in such a manner that
the seal fits tightly around the cable. Position
connector gasket, place connector over coil
spades and tighten the central screw to
specified torque to ensure proper gaskets
compression. The coil itself can be rotated
360° to select the most favourable position
for the cable entry.
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:
V-supply The supply voltage to the
barrier.
T-ambient The ambient temperature in
degrees C.
R-barrier The maximum barrier end to
end resistance.
R-loop The maximum resistance in
lead wire
R-coil The resistance of the solenoid
coil at Tambient
R-coil = 406 Ω
+
I-loop Loop current in the circuit:
I-loop =
This current must always be greater than
or equal to 25mA for proper operation of
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.
To prevent electrostatic hazard, clean coil
surface only with a damp cloth. Do not use
solvents.
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.
