INSTALLATION AND MAINTENANCE INSTRUCTIONS
Monostable series 552-553 solenoid valves for safety applications
Aluminium or stainless steel body, 3/8"-1/2" thread – NAMUR interface,
according to IEC standard 61508 (SIL approval)
DESCRIPTION OF THE CERTIFICATION
Versions concerned by the certifi cation, suffi x SL:
Series 552-553, aluminium or stainless steel body, monostable
(spring return), 3/2 NC (normally closed) function or 5/2, version
isolated from the outside atmosphere. Versions without manual
override or with impulse-type manual override:
- with 3/8"-1/2" threaded connection (Do not connect the pres-
sure supply to the exhaust port 3. The "environmentally-protected"
construction is not adapted for a "distributing" function or use in NO
function. Contact us for functions available in specifi c versions)
- with NAMUR interface for direct mounting to single acting (function
3/2 NC) or double acting (function 5/2) pneumatic actuators. The
function of the valve is convertible from 3/2 NC to 5/2 by mounting
the supplied 13/2 NC or 5/2 interface plate at the bottom of the valve
(fi g.3e, 13b, ref. 1a and 1b). (Do not connect the pressure supply
to the exhaust port 3. The "environmentally-protected" construction
is not adapted for NO function. Contact us for function available in
specifi c version)
The use of any other product is prohibited and does not con-
stitute a part of this approval.
IEC standard 61508 describes a set of general requirements for
each phase in the life cycle of a safety system. The reliability analysis
performed by EXIDA has shown that these valves are suitable for use
in systems with a safety integrity level of up to and including SIL 3.
For the installation, maintenance, testing and putting into operation
of these valves, we recommend using the documents according
to IEC standard 61508.Depending on the SIL level, they lay down
the necessary measures relating to the authority, qualifi cation and
independence of the responsible personnel. All indications and
provisions contained in the general installation and maintenance
instructions form the basis of the above-mentioned documents. To
ensure the reliability, all additional provisions mentioned hereinafter
must also be adhered to.
Connect pipes for the required functions in accordance with this
documentation and the port markings on the product.
- Make sure no foreign matter enters the circuit to prevent blocking
the valve function. Restrict the use of sealing tape or sealing matter
to a minimum.
- These valves are intended for use with clean and dry air or inert
gas. Recommended minimum fi ltration: 50 microns. The dew point
of the fl uid used must be at least –10°C (18°F) below the minimum
temperature to which the fl uid may be exposed. When using lu-
bricated air, the lubricant must be compatible with the elastomers
used. Instrument air in compliance with ANSI/ISA standard S7.3
(1975) exceeds the necessary requirements and is, therefore, an
acceptable fl uid for these valves.
- All exhaust ports of the valves and pilots must be protected with
the stainless steel exhaust protectors supplied with the product (see
rep. 3).When used in a pipe connection, the valves must be protected
with (an) appropriate fi lter(s). Connect these exhaust protectors to
port 3 (3/2 NC) or ports 3 – 5 (5/2) of the valves.The reliability of
the valve cannot be guaranteed if an exhaust protection other than
that supplied is used. In this case, please contact Asco or one of its
authorised representatives.
- Allowable temperature range: -40°C to +60°C
- Maximum working pressure:
- 2 to 10 bar
- 2 à 8 bar (ISSC/PISC/PISCIS/CFSCIS/CFSDIS/CFVTIS)
DESCRIPTION
ATEX 94/9/EC versions: See "Special conditions for safe use".
Versions isolated from atmosphere: The internal parts of the
valve are isolated from the outside atmosphere in order to provide
protection in aggressive environments. All the exhaust ports of the
spool valve are pipable, providing better environmental protection,
particularly recommended for sensitive areas such as clean rooms
3/2 NC
5/2
and applications in the pharmaceutical or food processing industries.
It is necessary to connect pipes or fi ttings to the exhaust ports to
protect the internal parts of the spool valve if used outside or in
harsh environments (dusts, liquids etc.).
SPECIAL CONDITIONS FOR SAFE USE
The spool valve must be kept in its original packaging as long as it
is left unused. The protective covers must not be removed from the
connection ports and solenoid operators.
Storage conditions: protected from exposure to weather; storage
temperature: -40 C to +70°C ; relative humidity: 95 %
After storage at low temperature, the spool valves must gradually
be brought to operating temperature prior to pressurisation.
The spool valves are intended to be operated within the technical
characteristics specifi ed on the nameplate. Changes to the products
may only be made after consulting the manufacturer or his representa-
tive. These solenoid spool valves are designed to operate with
fi ltered air or neutral gas. Do not exceed the maximum allowable
pressure of the valve = 8/10 bar. Caution: observe the minimum pilot
pressure of 2 bar. Installation and maintenance of the valve must
be carried out by qualifi ed personnel only.

Caution:
- Before any intervention, turn off the electrical current to power
off the components.
- Depending on the voltage, electrical components must be
grounded according to local standards and regulations.
Most valves are equipped with coils designed for continuous
duty. To prevent the risk of personal injury, do not touch the so-
lenoid operator which can become hot under norrmal operating
conditions. If the valve is easily accessible, the installer must
provide for protection against accidental contact of the solenoid
operator.
MAINTENANCE
! Prior to any maintenance work or putting into operation,
power off, depressurise and vent the valve to prevent the risk
of personal injury or damage to equipment.
ATEX versions: Strictly follow all procedures recommended by
Directive 99/92/EC and associated standards.
• Cleaning
Maintenance of the valves depends on the operating conditions.
They must be cleaned at regular intervals. During servicing, the
components must be checked for excessive wear. The components
must be cleaned when a slowing down of the cycle is noticed even
though the pilot pressure is correct or if any unusual noise or a
leak is detected.
• Sound emission
The emission of sound depends on the application, medium and
type of equipment used. The exact determination of the sound
level can only be made by the user having the valve installed in
his system.
• Preventive maintenance
- Operate the valve at least once a month to check its function.
- If problems arise during maintenance or in case of doubt, please
contact ASCO NUMATICS or one of its authorised representa-
tives.
• Troubleshooting
- Incorrect outlet pressure: Check the pressure on the supply side
of the valve; it must correspond to the values indicated on the
nameplate.
Caution: observe the minimum pilot pressure value of 2 bar.
To avoid personal injury or damage to equipment, check that the
valve operates correctly before putting it back into operation.
