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 ISO5211 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

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 IEC61511.
–In Low Demand Mode up to SIL2
–In High Demand Mode up to SIL1
Taking into account the required minimum hardware fault tolerance (HFT=1), the
product can also be used up to SIL3 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
è2Safety.
–Periodic tests (function test) è11Maintenance, è11.1 General.
–Ambient conditions and other technical specifications è15Technical data.
4.4 Limitations of use
If used in a safety-related system, the service life is limited to 8years subject to
compliance with the operating conditions.
–Recommended interval for a complete function test: 1year
–Maximum permissible interval for a complete function test: 3years
When a function test is negative, maintenance work must be carried out immedi-
ately.

A shaft projects outward through the housing on both sides. It transmits the
reaction torque to a process valve and, if applicable, a limit switch or position
sensor. The end stops can be adjusted in the range of 5° thanks to end-position
adjustment on both sides.
5.2 Function
The piston movement of the quarter-turn actuator is converted into a swivel move-
ment of the transmission shaft by Rack & Pinion kinematics (gear rack/pinion).
The swivel angle is 90° to a maximum of 180°, depending on the product version.

10 Commissioning
Requirement: The quarter-turn actuator must be fully assembled and connected.
1. Ventilate the quarter-turn actuator slowly.
2. Check that it is working correctly at a low speed:
–Direction of rotation of the quarter-turn actuator
–Position of the process valve
11 Maintenance
11.1 General
Low Demand Mode:
–The product is maintenance-free in intended use.
High Demand Mode:
–Check that the product is working properly at regular intervals. The check
interval depends on the operating conditions.
11.2 Proof test (Proof Test)
The proof test consists of a Full Stroke test of the actuator. Full rotation of
the shaft is tested at the connection to the process valve dependent on the
switching position of the control valve. The switching position of the shaft can
be determined visually (position of the shaft groove) using a position sensor or
something else suitable.
–Carry out the proof test at least once every 3 years.
During the proof test, the safety of the application must be ensured.
1. Trigger the rotation of the shaft at the control valve.
2. Measure the time taken until the quarter-turn actuator has caused the shaft
to rotate fully.
ÄThe test is successful if the quarter-turn actuator completes the move-
ment within the switching time intended for control by the control valve.
3. Check the actuator externally (visual inspection).
ÄThe test is successful if no defect, leakage or contamination is detected.
4. Document the test results.
