9 Operation
9.1 Basic requirements
The following points must be observed during operation.
General requirements
• Do not touch the product or any connected parts during operation (accident
prevention).
• Never switch off, modify or bypass safety devices.
• Observe the system descriptions for your valve system components. See
g 1.2 Additional documentation.
In case of malfunctions during operation
• In case of a malfunction that presents an immediate danger for employees or
systems: Switch off product.
• If a malfunction cannot be remedied: Inform the customer service. Contact
data: see back cover.
10 Service
The following operation-related activities are necessary to ensure safe use of the
product with minimal wear and tear:
• Inspection. See g 10.2 Inspection
• Cleaning. See g 10.3 Cleaning
• Maintenance. See g 10.4 Maintenance
10.1 Notes on safety
To eliminate risks during service, observe the notes on safety. See g 2. Safety.
10.2 Inspection
During inspection, check the product for damage and contamination at regular
intervals.
10.2.1 General requirements
Use in normal ambient conditions

tem.
Use in aggressive ambient conditions
Aggressive ambient conditions include, for example:
• High temperatures
• Heavy accumulation of dirt
AVENTICS™ AES | R412018150-BAL-001-AC | English
Diagnosis
No error has occurred.
An error has occurred.
• 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
seals will lead to pneumatic leaks and non-compliance with the degree of pro-
tection. Inspect seals more frequently (material protection).
• Enter the adapted inspection intervals in the system-specific maintenance
plan (accident prevention, material protection).
10.2.2 Procedure
Preparation
All work has to be prepared as follows:
1. Close off dangerous areas (accident prevention).
2. Make sure the system or system part is not under pressure or voltage (acci-
dent prevention, material protection).
3. Protect the system against being restarted (accident prevention).
4. Allow the product and adjacent system parts to cool down (accident preven-
tion).
5. Wear PPE (accident prevention).
Visual inspection
Visually inspect for integrity.
Detailed inspection
• Check identifications and warnings on the product: Labels and identifications
must be legible (accident prevention, material protection).
Replace hard-to-read labels or identification immediately.
• Check to make sure that all fittings are properly connected.
• Check the safety devices on the system.
• Check the product functions.
10.3 Cleaning
10.3.1 General requirements
Cleaning intervals
• The system owner specifies the cleaning intervals in line with the ambient
conditions at the operating site.
• Observe the information in the system documentation.
Aids
• Only use water for cleaning and a mild detergent, if necessary (material pro-
tection).
Notes
• Penetrating fluids destroy seals and cause damage to the product (material
protection).
10.3.2 Procedure
Preparation
1. Close all openings with suitable safety devices so that no cleaning agent can
enter into the system.
Cleaning
1. Remove all dust deposits from the product and the adjacent system parts.
2. If necessary, remove other production-related deposits from the product and
the adjacent system parts.
10.4 Maintenance
In normal ambient conditions, the product is maintenance-free.
Notes
• Observe the maintenance plan for the overall system: Further maintenance
tasks may result from the maintenance plan for the overall system and the
maintenance intervals specified therein.
10.5 After service
After completion of the service work, carry out the following steps:
1. Remove all tools and devices from the work area.
