In the Ex area, 135°C is the reference temperature for determining
the temperature class (T4) and for further considerations with
respect to the safety distance from the smoldering temperature.
The permissible ambient temperature range is -10°C ≤ Ta ≤ 50°C.
The C01 series electrical solenoid valves of type 30MM-ATEX in
accordance with PTB 09 ATEX 2041 X of AVENTICS can be
combined in all aforementioned zones with the mechanical valves
listed in section "1 About This Documentation". The interconnection
has been tested for compliance with explosion protection. Also
observe the valid operating instructions for the solenoids.
General safety instructions
W Observe the general technical rules for the selection and
operation of devices.
W Take suitable measures to prevent unintended activation or
impermissible interference.
W Do not remove connection lines or valves that are part of a
system under pressure.
W Device ignition protection classes must be installed only for the
appropriate zones!
W All connected electrical devices must be suitable for their
respective functions.
W Avoid electrostatic charges.
W Comply with the ambient conditions specified in the operating
instructions at all times.
During assembly and commissioning
W After removing the packaging and during assembly, make sure
that no contamination enters the system.
W Assembly work in Ex areas may only be carried out in
accordance with the local installation regulations.
Furthermore, observe the following guidelines:
– Assembly is only permitted in non-Ex atmospheres and with
a fire permit.
– Additional safety precautions are necessary if there is a
probability of hydrogen sulfide, ethylene oxide and/or
carbon monoxide. These substances have a very low
ignition energy threshold!
– Where nevertheless an explosive atmosphere can be
expected, use only non-sparking tools for these substances.
W Install the valves in a superior system.
W Always observe the nationally valid installation guidelines
(e.g. EN 60079-14).
W The devices are designed for protection class IP65 and may
require further protection if used under more adverse ambient
conditions.
W Note the EC prototype test certifications for electrical
equipment and any requirements contained therein.
W Establish a low-induction connection between the PA port (if
available) of the associated equipment and the system's PA. At
the least, establish a conductive connection between the
mechanical body and the PA.
W The accuracy of the interconnection between the mechanical
valve and electromagnetic valve coil in terms of explosion
protection must be tested and certified by the person installing
the system.
W The system owner must take precautions to protect against
lightning.
During operation
W Operation of the valves is only permissible in fully assembled
housings that are free of defects. Operation is prohibited in
damaged housings.
W Accessory parts for use in explosive areas must comply with
the requirements stipulated in the European directives and
national laws.
W Do not subject the system to deflection, torsion, impact, or
shock.
W Only air prepared outside the Ex area that does not attack the
system or its sealing materials is permitted for use.
W During installation, make sure that the exhaust in a dust Ex
area exits in accordance with the IP protection class
appropriate to the zone.
W The maximum surface temperatures depend on the
installation situation and are the responsibility of the customer
or system owner. During intended use, no temperature
increases > 20 K can be reached on the outer housing parts.
Temperature class T4 is adhered to.
W All exterior materials consist of suitable low-spark materials.
However, the system owner is responsible for checking for
ignition hazards due to sparks during operation of the
complete machine. Lightweight metal parts must be protected
against external shock energy when installed.
W In explosion group IIB and zone 1, projected surfaces for
2
plastics > 100 cm are not permitted; with dust, 100 cm
acceptable.
W Discharges of medium in the Ex area must be diffuse.
W Icing is not permissible!
During maintenance and repair
W Maintenance and repair measures may only be performed by
personnel with equal or comparable qualification according to
TRBS 1203.
W Avoid contact between external liquid or corrosive media and
the device.
W Maintenance tasks must only be performed in non-Ex
atmospheres. A fire permit is required.
W Devices in Ex areas must be cleaned regularly. The intervals
must be stipulated by the system owner in accordance with the
local environmental conditions and the respective IP protection
class.
W Accessory parts for use in explosive areas must comply with
the requirements stipulated in the European directives and
national laws. Components may only be exchanged for original
spare parts that are also approved for use in explosive areas.
W Maintenance of internal components cannot be conducted on
site. Send the device to the manufacturer for inspection.
W After service and/or maintenance, all barriers and warnings
must be returned to their original locations.
