Supplementary safety instructions for P8S- GPFLX/
EX sensors installed in Ex-areas
Serious, even fatal, damage or injury may be caused by the hot moving
parts of the P1D cylinders in the presence of explosive gas mixtures and
concentrations of dust.
Instructions for use
Safety instructions
• Cylinder sensor ATEX classed for category II3G and II3D
• Ambient temperature Ta = -20 °C to +45 °C
• Temperature class T4, or max. surface temperature of T = 135 °C
• Protection class IP67
• Read installation instructions before startup
• Installation, connection and commissioning must be carried out
by trained personnel
Applications
• This sensor is designed for use in the T-groove of cylinders, and
detects the magnetic field in potentially explosive areas. The
sensor can only be installed in the T-groove of these cylinders.
• The sensor may also be installed on round cylinders by means of
the following attachments:
P8S-TMC01 Suitable for P1S and P1A diameter 10 - 25 mm
P8S-TMC02 Suitable for P1S diameter 32 - 63 mm
P8S-TMC03 Suitable for P1S diameter 80 - 125 mm
The following data applies to these attachments:
- Ambient temperature Ta = 0 °C to 45 °C
- Low energy absorption to EN 50 021
• The sensor may also be installed on tie-rod cylinders or profile
cylinders by means of this attachment:
P8S-TMA0X Suitable for P1D-T diameter 32 - 125 mm, P1E-T
diameter 160 – 200 mm and C41 diameter 160 – 200 mm
Installation
General: The sensor must be protected from UV radiation. The cable
must be installed such that it is protected from external influences,
for example it may be necessary to attach an external strain relief to
the cable.
Technical data for sensor
Operating voltage Ub = 18 to 30 V DC
Max. load current Ia d" ¡Ü 70 mA
Ambient temperature: -20 °C to 45 °C
Commissioning
When connecting the sensor to a power source, please pay attention
to the following
a) the load data (operating voltage, continuous load current)
b) the wiring diagram for the sensor
Maintenance
Our P8S-GPFLX/EX cylinder sensor is maintenance free, but the
cable connections should be checked at regular intervals.
The sensor must be protected from UV radiation. The sensor must be
kept clean on the outside, and a layer of dirt thicker than 1 mm must
never be allowed to form. Strong solvents should not be used for
cleaning as they may damage the sensor.

Ex means that this product is intended for use in potentially
explosive atmospheres
II Stands for the equipment group (I = mines and II = other
hazardous areas)
3G Stands for the equipment category 3G means the equipment
can be used in zone 2 where there is a risk involving gases,
vapours or mists of combustible liquids
EEx means that this is an electrical product intended for use

T4 X If equipment is in temperature class T4, the maximum
surface temperature must not exceed 135 °C. (To guarantee
this, the product has been tested to ensure that the maximum
is 130 °C. This provides a safety margin of 5 °K.) X Must be
installed in accordance with the installation manual
3D Stands for equipment category 3D in zone 22 where there is
a risk involving dusts.
135 °C Maximum permitted surface temperature on the motor in
atmospheres containing potentially explosive dusts.
IP67 Satisfies protection class IP67
Components such as cylinder attachments,
tube fittings, tubes, etc.
Components
Parker Hannifin guarantees that our cylinder attachments, tube
fittings, tubes, etc. are not subject to the provisions of the ATEX
directive.
A component means any item essential to the safe functioning of
equipment and protective systems but with no autonomous function.
Components intended for incorporation into equipment or protec-
tive systems which are accompanied by an attestation of conformity
with the ATEX directive, including a statement of their characteristics
and how they must be incorporated into products, are considered
to conform to the applicable provisions of directive 94/9/EC. Ex-
components as defined in the European standard EN 50014 are
components in the sense of the ATEX directive 94/9/EC as well.
Components must not have the CE marking affixed unless otherwise
required by other directives.
Examples of components:
• terminals
• push buttons assemblies
• relays
• empty flameproof enclosures
• ballasts for fluorescent lamps
• meters (e.g. moving coil)
• encapsulated relays and contactors, with terminals and/or flying
leads
