Safety instructions related to the product and technology
Danger of injury due to stored energy (compressed air)!
When the system is at a standstill, there is still a danger due to stored energy
(compressed air).
O Generally avoid storing compressed air.
O Exhaust the system before working on it.
O Remove all other sources of danger in the immediate work area that may
result from stored energy in the system.
Danger of injury by dismantling the valve!
Pre-tensioned springs may suddenly be released when dismantling the valve.
O Never dismantle the valve.
O Do not remove the mounting screws for the valve cover (
O Do not remove the mounting screws for the pilot valve (
O Do not remove the mounting screws for the sensor housing (
O Do not replace or disassemble the sensor, or change its position.
Injuries if system-specific limits are not complied with!
The operating conditions for the IS12-PD valve may deviate from the system
operating conditions.
O Always observe the information in the documentation for the superior system.
O Before assembly, contact the system manufacturer or AVENTICS GmbH to
clarify any contradictions or questions.
Danger of burns caused by hot surfaces!
Touching the surfaces of the valves and adjacent components during operation
could cause burns.
O Let the relevant system component cool down before working on the valve.
O Do not touch the relevant system component during operation.
Danger of injury if assembled under pressure or voltage!
Uncontrolled system movements are possible.
O Make sure that the relevant system part is not under voltage or pressure
before you assemble the product.
O Protect the system against being switched on.
Personal protective equipment
O Wear appropriate protective clothing during assembly and maintenance. Observe
the applicable occupational safety regulations for the system.
Responsibilities of the system owner
As the owner of a system that will be equipped with an IS12-PD valve with spool
position detection, you are responsible for
W
ensuring intended use,
W
ensuring that operating employees receive regular instruction,
W
ensuring that the operating conditions are in line with the requirements for the
safe use of the product,
W
ensuring that no unauthorized repairs are attempted if there is a malfunction.
3 General Instructions on Equipment and
Product Damage
Valve damage due to falling!
If the module falls, the product may be damaged even if no damage is visible.
O Always transport the module carefully.
O If the module has fallen, it may no longer be installed.
O Check the packaging when you receive the product. If the packaging is
damaged, the module must not be installed.
Spool position detection malfunction due to magnetic sources!
Spool position detection may malfunction due to magnetic sources.
O Make sure that no magnetic sources are located near the valve.
Mechanical loads!
The device may be damaged. The protection class IP65 is no longer guaranteed.
O Do not mechanically load the vale, the electrical connecting cables, or the
pneumatic tubing.

Function
5
IS12-PD series valves are electrically operated pneumatic 5/2 directional valves
with an integrated spool position detection. Spool position detection is realized by
means of the following system: A magnet is integrated in the piston (spool) of the
valve and an ST4 series proximity sensor with an M8x1 connection is installed in a
sensor housing on valve side 14.
The sensor LED indicates the position of the spool. This allows the user to detect
whether the valve is in the home position (sensor LED is lit) or in the switching state
(sensor LED is not lit). In addition, the position of the sensor is transferred to the
controller via the M8 connection, PIN 4 (OUT).
The sensor is switched on when the spool is located on valve side 14, meaning in
home position. In this case, the sensor LED is lit.
The sensor is switched off when the spool is located on valve side 12, meaning in the
switching position. In this case, the sensor LED is not lit.
Depending on the order, IS12-PD series vales have different features:
W
With or without manual override (MO)
W
With internal or external pilot
Home position, sensor LED lit
When the valve is not actuated electrically, it is in home position. The spool is
positioned so that connections 1 and 2 and connections 4 and 5 are connected
respectively. With typical use, connection 2 is under pressure while connection 4 is
pressure-free. The sensor LED is switched on and indicates that the valve is in the
home position. The output voltage is applied to pin 4 (OUT). To ensure the system is
not under pressure in home position, the working connection to the system must be
connected at connection 4.
Switching position, sensor LED not lit
When the valve is actuated electrically, it is in switching position. The spool is
positioned so that connections 2 and 3 and connections 1 and 4 are connected
respectively. With typical use, connection 2 is pressure-free while connection 4 is
under pressure. The sensor LED is switched off and indicates that the valve is in the
switching position. 0 volts are applied to pin 4 (OUT). To ensure the system is under
pressure in the switching position, the working connection to the system must be
connected at connection 4.
Sensor signal change when pressurizing port 4
When the valve is switched on, the spool moves from valve side 14 to valve side 12.
During spool movement, the signal of the sensor switches from "ON" to "OFF".
Sensor signal change when exhausting port 4
When the valve is switched off, the spool moves from valve side 12 to valve side 14.
During spool movement, the signal of the sensor switches from "OFF" to "ON" if port
4 is connected to port 5.
