W
The dual valve must be attached in such a way that it cannot be loosened by jolts, vibrations,
or the like.
W
The position of the sensor was fixed at the factory and secured with a clamping screw and
resin. The sensor must not be replaced or disassembled, or its position changed. The sensor
housing (4) is bolted to the valve cover (3) and secured with resin. The sensor housing must
not be replaced or disassembled, or its position changed.
O
Make sure that the dual valve is only used as described in "Intended use".
Preparing for installation
Prepare for assembly as follows:
1. Stop system operation and protect it against being switched on.
2. Return all suspended loads to a statically secure position or remove them from the system.
3. If required, exhaust stored compressed air from system parts in the immediate work area.
4. Make sure the relevant section of the system is not under pressure or voltage and protect it
from being switched on.
5. Secure self-turning or other movable system parts before starting assembly.
6. Before assembly, check the sensor cable for damage. If the sensor cable is damaged, you
must replace the entire valve. In this case, we recommend that the entire dual valve is
replaced.
Installing the dual valve
Any mounting orientation may be used with the dual valve.
Assembly consists of the following steps:
W
mechanical fastening to the system,
W
connection to the compressed air supply of the pneumatic system,
W
connecting the sensors
W
coil connection.
Mechanically fastening the dual valve to the system
O
Mount the base plate on the assembly surface with 4 x M6 fixing screws in a way that
prevents mechanical strain (see 9
O
Make sure that the dual valve that it cannot be loosened by jolts, vibrations, or the like.
O
Install the dual valve in your system in a manner where the pneumatic connections are
always accessible (maximum dimensions: 160 mm x 152 mm x 160 mm).
Connecting the compressed air supply
The valves are supplied with compressed air via the base plate.
O
Make the pneumatic connections as follows:
– Connection 1 to the supply pressure,
– Connections 2 to the working connections.
Connections 3 (
–7) are equipped with a silencer at the factory.

Danger of injury!
Electric shock due to incorrect power pack!
O
Only use the following power supply for the dual valve: 24 V DC PELV circuits in
accordance with DIN EN 60204-1.
O
The PELV power source must be a safety isolation transformer in accordance with
IEC 61558-1 or IEC 61558-2-6, or a power source offering the same degree of safety as a
safety isolation transformer.
O
Make sure that the power supply of the power pack is always less than 300 V AC (outer
cable – neutral wire).
Connect the sensor
The contacts on the M8x1 connection have the following pin assignment (see
Contact Pin assignment acc. to EN 60947-5-2:1998
Pin 1 (+) Brown (BN)
Pin 3 (-) Blue (BU)
Pin 4 (OUT) Black (BK)
Malfunction due to damaged sensor cable!
If the seal in the sensor plug is missing or defective, protection class IP65 is not achieved.
O
Make sure that the seals are integrated in the plug and not damaged.
Damage to the sensor due to excessive voltage!
The ST4 sensor may only be operated with 10–30 V DC even if you use 110 V AC or 230 V AC
coils.
O
Make sure that the ST4 sensor is always operated within the voltage limits.
O
Connect the sensor plug and the knurled nuts to the controller. See the table for the pin
assignment (above).
We recommend using short circuit protection.
for distances of holes).
WARNING
NOTICE
Connecting the coil
Fig. shows that the coil can be mounted in a 180° radius in 5 different positions (0°, 45°, 90°,
2
135° and 180°).
To connect the coil, you need cables with the following connections:
W
An electrical connector according to ISO 440, form A, CN1 series
W
or one M2x1 socket, 3-pin, A-coded.
The cable and connectors are not part of the scope of delivery. The pin assignments of the coils
are shown in Fig.
O
Connect the electrical connector or the M12 socket to the coil. Make sure that the seals have
been inserted correctly. Tighten the screw on the coil (form A) or the knurled nuts to the M12
plug.
Screw tightening torque: 0.4 +0.1 Nm
9 Commissioning
Danger of injury while working on the system!
Working while the system is running can cause major injuries from moving machinery.
O
Maintain a sufficient safety distance to moving machine components.
O
Do not work on the system while it is running.
Risk of injury when actuating the manual override!
Uncontrolled movement of the system components!
O
Before actuating the manual override, make sure that it will not trigger uncontrolled
system movements.
Checking the connections
O
Before commissioning, make sure that all plugs are correctly connected to ensure
protection class IP65.
Function test
Commissioning can be simplified by actuating the valves with the manual override (MO). The MO
on the IS12-PD valves is "without detent". This means that the valve switches to home position
when you discontinue actuating the MO.
Checking the "slider position detection" function
O
Before initial operation, check whether the "slider position detection" function is working
properly.
– If the valve is not actuated (electrically or mechanically on the MO), the sensor LED should
be lit. The output voltage is applied to pin 4 (OUT).
– If the valve is actuated (electrically or mechanically on the MO), the sensor LED must not
be lit. 0 volts are applied to pin 4 (OUT).
Check of redundant safety functions

SF1: Safe exhaust
A pressure volume must be available on working connection (2) that can be exhausted, such as
a cylinder, to test safe exhaust, as shown in figure
O
Check the "safe exhaust" function as follows:
Exhaust the working connection
Pressure must be applied to the working connection, e.g. by pressurizing a cylinder
1. Valve 1:
Not actuated
Pressure must be applied to the working connection, e.g. by pressurizing a cylinder
2. Valve 1:
