7.1 Notes on safety
Danger to life due to dangerous operating states when using serial commu-
nication
If the interface is used, interference from radio waves or other electrical inter-
ference can trigger a reaction. The product no longer responds to the defined
set point.
Make sure that no interference is present when using the interface.
u
7.2 Basic requirements
Product-specific requirements
• In case of supply pressure interruption: Switch off 24 V supply voltage (mate-
rial protection).
7.3 Step-by-step commissioning
Procedure
1. Switch on the pneumatic supply.
2. Screw in the sealing cap to the stop.
3. Switch on the 24 V DC supply voltage.
8 Operation
8.1 Basic requirements
General requirements
• Never switch off, modify or bypass safety devices.
In case of malfunctions during operation
• In case of a malfunction that presents an immediate danger for employees or
systems: Switch off product.
• Carry out analysis and troubleshooting of malfunctions. See
bleshooting.
9 Service
9.1 Inspection
9.1.1 General requirements
Use in normal ambient conditions
• Inspection interval: The product must be checked monthly for contamination
and damage.
Use in aggressive ambient conditions
Aggressive ambient conditions include, for example:
• High temperatures
• Heavy accumulation of dirt
• Proximity to grease-dissolving liquids or vapors

Aggressive ambient conditions lead to further requirements for inspection:
• Adapt the inspection interval for seals to the ambient conditions.
NOTICE! Seals age faster under aggressive ambient conditions. Defective

9.1.2 Procedure
Gray
Preparation
Shield
1. Do not carry out any work on the system during preparation.
2. Close off dangerous areas.
3. Make sure the system or system part is not under pressure or voltage.
4. Protect the system against being restarted.
5. Allow the product and adjacent system parts to cool down.
6. Wear PPE.
Visual inspection
Visually inspect for integrity.
u
Detailed inspection
• Identifications and warnings on the product: The system owner has to replace
labels or warnings that are difficult to read immediately.
• Check the compressed air connections.
• Check the lines.
• Check the seals.
• Check the ground connection.
• Check to make sure that all fittings are properly connected.
• Check the safety devices on the system.
• Check the product functions.
9.2 Cleaning
9.2.1 General requirements
Cleaning intervals
• The system owner specifies the cleaning intervals in line with the ambient
conditions at the operating site.
Aids
• Only clean the product with damp cloths.
• Only use water for cleaning and a mild detergent, if necessary (material pro-
tection).
NOTICE! Make sure that no water or water mist can enter the product via the
compressed air connections. Penetrating fluids destroy seals and cause dam-
age to the product.
9.2.2 Procedure
1. Close all openings with suitable safety devices so that no cleaning agent can
enter into the system.
2. Remove all dust deposits from the product and the adjacent system parts.
3. If necessary, remove other production-related deposits from the product and
the adjacent system parts.
9.3 Maintenance
In normal ambient conditions, the product is maintenance-free.
9.4 After service
If no damage has been detected and the operator has not reported any malfunc-
tions, the product can be reconnected to the power supply and put back into op-
eration.
10 Disassembly and exchange
Disassembly is only required if the product has to be exchanged, installed in a dif-
ferent location or disposed off.
