Instructions related to the product and technology
W
Only mount the solenoid coil with electrical connector onto pneumatic valves
or pneumatic cylinder-valve units from AVENTICS GmbH which have been tested
in compliance with the ATEX directive or qualify as devices without their own
potential source of ignition.
W
Never loosen any cables, lines or valves if the system is under voltage
or pressure.
W
For base devices with their own potential source of ignition, also observe
the operating instructions of the respective device.
W
Only use cables that are suitable for temperatures of –20°C to +90°C,
in accordance with EN 60079-14.
W
Make sure the relevant system component is not under pressure or voltage
before assembling the product or when connecting and disconnecting plugs.
Protect the system against being switched on.
W
Do not place any deflection, torsion, or impact loads on the unit.
Protected installation may be necessary under certain circumstances.
W
To avoid short circuits and interruptions, make sure that connection cables
and strands are not sharply bent.
W
If, by loosening the center screw, the electrical connector has been separated
from the solenoid coil several times, the electrical connector and the seal must
be exchanged for original spare parts.
W
Before commissioning, make sure that all conductive metal parts are electrically
connected to each other and that the device is grounded in accordance
with the applicable regulation.
W
Make sure that the given values for current and voltage are not exceeded.
W
Do not disconnect the electrical connector from the solenoid coil while under
voltage.
W
Only use media that do not corrode the system and the sealing materials
contained therein.
W
Before commissioning, make sure that the entire machine or system complies
with the ATEX and EMC directives.
W
The maximum permissible working pressure depends on the pneumatic base
device.

Use in Explosive Areas

Danger of explosion with open or damaged products!
Open or damaged devices cannot be operated safely in explosive areas.
O Never open the device in an explosive atmosphere.
O Before commissioning, make sure that the device is completely closed
and undamaged.
Pneumatic base valves from AVENTICS GmbH which have been tested in compliance
with the ATEX directive or qualify as devices without their own potential source
of ignition can be electrically actuated with the solenoid coil and electrical connector.
The solenoid coil with electrical connector is electrical equipment designed for use
in explosive areas.
O Always observe the technical data and limits indicated on the name plates,
particularly the data from the ATEX identification.
ATEX identification
II 3G Ex nA IIC T4 Gc X
II 3D Ex tc IIIC T125°C Dc X
-10°C ≤ Ta ≤ 50°C IP65
Please note the following regarding device identification with "X":
The devices are designed for protection class IP65 and may require further
protection if used under adverse ambient conditions.
W
Without additional mechanical protection, installation is only permitted in areas
with a low risk of mechanical danger (according to EN 60079-0, 26.4).
W
The installation location for the plug connector must be protected against light.
W
Protection class IP65 is only attained if the end device (base device, coil,
and electrical connector) is fitted properly. Use the provided seal and observe
the specified torque when tightening the mounting screw.
W
Only disconnect the EX plug connector from the end device in a voltage-free state.
On the name plate, the device's year of manufacture is coded in the date
of manufacture as follows:
yyWww (yy = year of manufacture; ww = week of manufacture)
Example: "15W17" means year of manufacture 2015, week 17

Device Description

The components of the solenoid coil with electrical connector are depicted
and named in fig. 1.
DANGER
6 Mounting the Solenoid Coil
To mount the solenoid coil with electrical connector, the solenoid coil must
be mounted to the base valve and the electrical connector electrically connected.
Mounting on the base valve
1. Remove the mounting nut from the armature system of the base valve.
2. Slide the solenoid coil onto the armature guide tube of the base valve.
The coil can be adjusted in 45° staggered increments and must be completely
engaged.
3. Tighten the solenoid coil back onto the armature guide tube of the base valve.
Tightening torques:
– Metal nut 0.8 ± 0.12 Nm
– Plastic nut (open) 0.5 ± 0.075 Nm
– Plastic nut (closed with sealing edge) 1.3 ± 0.1 Nm
Connecting the solenoid coil
Removing the electrical connector
To connect the cables, the electrical connector must be removed from the solenoid
coil.
Damage of the cable sealing ring and seal due to incorrect disassembly!
Liquids and foreign objects could penetrate and destroy the device.
O Before commissioning, make sure that all seals and plugs are leaktight.
O Make sure that no dirt or other foreign particles come into contact
with the electrical connector components or the seal of the device.
1. Loosen the center screw (fig. 1, 3) on the electrical connector (1) and remove
the electrical connector from the solenoid coil (10).
2. Carefully remove the center screw (3) and seal (2) without damaging the seal (9).
3. Raise the electrical connector insert (8) out of the electrical connector (1)
by inserting a screwdriver into the recess (11).
4. Loosen the cable guide screw (6) and remove the thrust ring (5) and the cable
sealing ring (4) without damaging it.
Connecting the cable
1. Push the cable guide screw (6), the thrust ring (5), the cable sealing ring (4) and
the electrical connector (1) onto the cable.
O Observe this component order while mounting the cable guide.
O Especially observe the orientation of the thrust ring (5).
2. Connect the individual wires to the connection terminals (7) as shown
in the wiring diagram (fig. 2).
Tightening torque: 0.2 ± 0.1 Nm
The electrical connector is equipped with connection terminals (7)
with a sleeve terminal design. Use wire end ferrules.
Assembling the electrical connector
Depending on the application, the electrical connector insert can be mounted in 90°
increments.
1. Reinsert the electrical connector insert (8) into the electrical connector until
it engages.
2. Screw the cable guide screw (6) back onto the electrical connector
without damaging the cable sealing ring.
Tightening torque: 1.8 ± 0.2 Nm
O Place the center screw (3) and seal (2) carefully into the electrical connector.
Installing the electrical connector
1. Place the assembled electrical connector onto the three contacts
of the solenoid coil (10).
2. Make sure that the seal (9) is lying smoothly between the solenoid coil
and electrical connector.
3. Tighten the center screw (3) in the electrical connector
with a hexagon socket (WS2).
Tightening torque: 0.4 ± 0.1 Nm
Overcurrent protection
Danger of explosion!
Overcurrent, e.g. resulting from a short circuit, can cause an explosion
in explosive areas.
O Provide for overcurrent protection as per EN 60204-1 if the current in any
circuit can exceed either the rated value for a component or the current
carrying capacity of the conductor, whichever is the lower value.
O Before commissioning, make sure that the entire system is in accordance
with the ATEX and EMC directives.
O Make sure that the device and all conductive metal parts are electrically
connected and grounded.
