2 Safety
2.1 General safety instructions
–Only use the product in its original condition without unauthorised modifica-
tions.
–Only use the product if it is in perfect technical condition.
–Observe the identifications on the product.
–Before working on the product, switch off the compressed air supply and lock it
to prevent it from being switched on again.
–Take into account the ambient conditions at the location of use. Corrosive
environments reduce the service life of the product.
–Protect the product from fluctuations in pressure: use a pressure control valve.
Return to Festo
Hazardous substances can endanger the health and safety of persons and cause
damage to the environment. To prevent hazards, the product should only be
returned if explicitly requested by Festo.
–Consult your regional Festo contact.
–Complete the declaration of contamination and attach it to the outside of the
packaging.
–Comply with all legal requirements for the handling of hazardous substances
and the transport of dangerous goods.
2.2 Intended use
The quarter-turn actuator operates process valves in fluid systems, (e.g. ball
valves or butterfly valves).
NOTICE
The operating torque of the actuator must not be greater than the maximum
permissible torque specified in ISO5211 in relation to the size of the mounting
flange and coupling.
NOTICE
Depending on the design, part-turn actuators that are moved to a defined
switching position by spring force in a de-energised state lose at least 30% of
their calculated torque as a result of the relaxation of the spring assemblies and
friction.
• Take an appropriate safety factor into account in the application.
2.3 Training of qualified personnel
Work on the product may only be carried out by qualified personnel who can
evaluate the work and detect dangers. The qualified personnel have knowledge
and experience in process automation.
3 Additional information
–Contact the regional Festo contact if you have technical problems
èwww.festo.com.
–Accessories and spare parts èwww.festo.com/catalogue.
4 Information on functional safety
4.1 Achievable safety classification
The product is suitable for use as an element in a safety-related system in accord-
ance with IEC61511.
–In Low Demand Mode up to SIL2
–In High Demand Mode up to SIL1
Taking into account the required minimum hardware fault tolerance (HFT=1), the
product can also be used up to SIL3 in a redundant configuration of the entire
system.
NOTICE
The suitability for certain applications can only be determined in connection with
the assessment of further components of the subsystem. These must achieve the
same safety level.
4.2 Safety function
Double-acting semi-rotary drives DFPD-...-RD/-LD
The safety function is to switch the actuator to the defined safety switching
position. This switching movement is achieved by pressurising the corresponding
pressure chamber with compressed air. The value of the torque generated
depends on the pressure difference between the two pressure chambers sepa-
rated by the piston.
Single-acting semi-rotary drives DFPD-...-RS/-LS
The safety function is to switch the actuator to the defined safety switching
position when the compressed air is switched off and the spring chamber is
exhausted. This switching movement is achieved through the spring force of the
spring assembly.
4.3 Operating conditions
–General information on safe operation
è2Safety.
–Periodic tests (function test) è11Maintenance, è11.1 General.
–Ambient conditions and other technical specifications è15Technical data.
4.4 Limitations of use
If used in a safety-related system, the service life is limited to 8years subject to
compliance with the operating conditions.
–Recommended interval for a complete function test: 1year
–Maximum permissible interval for a complete function test: 3years
When a function test is negative, maintenance work must be carried out immedi-
ately.
