Damage to health due to loud noise!
Levels above 70 dB(A) may lead to damage to health!
Always wear ear protectors during operation.
u
Before commissioning, the installation has to be carefully inspected by a quali-
fied, trained professional.
1. Make sure that the technical specifications match the operating criteria of the
machine and/or the pneumatic system.
2. Always set the compressed air supply to a level that ensures that the mini-
mum operating pressure is adhered to (see

7.1.1 3/2 directional valves

Test Result
1. Solenoid A energized Valve is faulted, supply is shut off, downstream air exhausts
through port 3. Sensor A voltage is off, sensor B is on.
2. Reset valve by de-energiz- Valve is off, supply is shut off, and downstream air is ex-
ing both solenoids hausted through port 3. Sensors A and B are switched to
HIGH.
3. Solenoid B energized Valve is faulted, supply is shut off, downstream air exhausts
through port 3. Sensor A is on, sensor B is off.
4. Reset valve by de-energiz- Valve is off, supply is shut off, and downstream air is ex-
ing both solenoids hausted through port 3. Sensors A and B are on.
5. Solenoids A and B ener- Valve is on, compressed air supply is supplied downstream
gized through port 2, port 3 is shut off. Sensors A and B are off.
6. Solenoids A and B de-ener- Valve is off, supply is shut off, and downstream air is ex-
gized hausted through port 3. Sensors A and B are on.

Results from the test procedure other than those listed above indicate a valve
malfunction. See g 8. Care and
Failure of the valve to shift synchronously can be monitored with the help of the
sensors. This malfunction could happen for a variety of reasons, such as:
• Defective piston seals,
• Main valve elements experiencing a switching delay due to dirt or resinous oil,
• Insufficient electrical signals to valve solenoids; suitable voltage not available,
• Receipt of signals at solenoids not synchronous,
• Pilot valves experiencing a switching delay due to damaged components, dirt,
or resinous oil,
• Excessive water build-up in the valve.

8 Care and maintenance

8.1 Care

Damage to the product due to the use of solvents and aggressive cleaning
agents!
The product can be damaged if washed with a solvent or aggressive cleaning
agent. The chemical resistance of the valve material cannot be guaranteed if
exposed for such agents. Solvents and aggressive detergents will destroy the
surface, labeling, and seals of the product.
Make sure that no solvents and aggressive cleaning agents come into con-
u
tact with the valve.
Damage to the product due to washing at high pressures and temperatures!
The product will be damaged if you clean it with high pressure and/or at a high
temperature.
Make sure that the product is not cleaned with high pressure and/or at a
u
high temperature.
No special care is required for the safety valve. Note the following if you would
like to clean the valve:
1. Check that all seals and plugs for the plug connections are firmly seated so
that no humidity can penetrate the safety valve during cleaning.
2. Only clean the safety valve using a slightly damp cloth. Only use water to do
this and, if necessary, a mild detergent.
8.2 Maintenance
Risk of injury while working with a running system!
Working with the system while it is running can cause major injuries from mov-
ing machinery.
Bring the system into a state in which working movements are no longer
u
possible. Wait until all moving machine parts come to a standstill, and pro-
tect the system against being switched on.
In normal operation, the safety valve is maintenance-free. However to ensure the
correct function, the safety valve must be actuated at least once per month.
1. Activate the safety valve at least once per month.
2. Perform a functional test at least annually (see
The safety valve seals may age faster in aggressive ambient conditions. A dam-
aged seal can be recognized by parts of the seal visibly protruding from the hous-
ing gaps. Defective seals will lead to pneumatic leaks. Please return to factory in
case of faulty product.
1. Regularly check that the seals are in perfect order.
2. Immediately exchange the safety valve if the seals are defective.
3. Check regularly whether all plug connectors are firmly fitted.
4. Establish the maintenance intervals according to your ambient conditions and
store them in the system-dependent maintenance plan.
5. Observe the system-specific maintenance intervals.
In case of any maintenance requirements, it is advisable to replace the entire
safety valve as this is the only way of ensuring a life cycle value for the entire
valve.
The operator is responsible for determining the maintenance intervals.

9 Disassembly and exchange

Danger of injury if disassembled under pressure or voltage!
Uncontrolled movement of the system components!
Make sure that the system is not under pressure or voltage when you re-
u
move the safety valve from the system.
