3. General
3.1 Proper use
Linear actuators for continuous positioning are intended to be used exclusively for actuating final con-
trol elements (valves, vanes, etc.). Do not use these actuators for any other purpose. Otherwise, a ha-
zard of personal injury or of damage to or impairment of the operational reliability of the device may
arise.
3.2 Safety and precautions
When mounting the actuator in areas which may be accessed by unauthorized persons, take the requi-
red protective measures.
- Linear actuators perform movements for positioning vanes and valves. Handle properly and with ca-
re. Otherwise, a hazard of bruise injuries may arise.
- When changing the oil of the actuator, thoroughly remove any oil that may have run down on the
floor during the procedure to avoid accidents.
- Dispose of the waste oil in compliance with the respective local regulations. Make sure that no waste
oil reaches the water cycle
- Only qualified specialists who have been trained for these tasks are authorized to mount and adjust
the control actuator, and to make the electrical connection.
- When working on the actuator itself or its electronics always observe the locally valid accident pre-
vention regulations and the regulations concerning the construction of technical installations.
4. Storage
Linear actuators may be stored under moist and aggressive condition for a short time. The equipment
is protected against external corrosive influences. However, direct exposure to rain, snow, etc. must be
avoided
Interior areas of the actuator with risk of condensation are protected by desiccant placed in the follo-
wing locations:
Motor:. . . . . . . . . . . . . . . . . . . . . . . . . . . . under brake cover
Position sensor: . . . . . . . . . . . . . under position sensor cover
Electronics (delivered separately): . . . in terminal enclosure
The desiccant guarantees sufficient protection for approximately 150 days. It can be regenerated at a
temperature of 90° C within 4 h.
The desiccant must be removed prior to commissioning the actuator or the electronics.
4.1 Long-time storage
If you intend to store or transport the device for a longer time, we recommend to wrap it in plastic foil
and add desiccant. Regularly check if the desiccant is still active.
In the case of standstill periods of more than 6 months with extended thrust rod, the chromated spindle
surface must be treated with a corrosion inhibitor. Prior to re-commissioning the unit clean the thrust
rod to avoid damage to the stripper and thrust rod gasket.
5. Delivery settings
