Before any work is carried out on the actuator, ensure that
■
the planned measures (possible operation of valves, for example) will not result in injury to
persons or faults in the plant,
■
the actuator or plant section is properly isolated. In addition to the main circuits, also check that
any additional or auxiliary circuits are disconnected!
Furthermore, the general safety regulations have to be observed:
■
Disconnect all poles (also 24/48 V DC),
■
Prevent accidental reconnection.
■
Conrmthatequipmentisnotlive.
■
Ground and short-circuit equipment.
■
Fit barriers or covers to neighboring live components.
This can also be achieved by removing the connection hood.
14�1 General information
The actuators are virtually maintenance-free (for the relubrication intervals, refer to chapter 14.2).
We recommend submitting the actuators after commissioning or after approx. 50 operation hours to
a general inspection to verify that
■
correct functioning is guaranteed,
■
no unusual noises/vibration occur,
■
thexingcomponentshavenotbecomeloose,
■
no leakages occur.
The housing of the SEVEN actuator consists of an aluminum alloy which is corrosion resistant un-
der normal environmental conditions. If the paint was damaged during assembly, it can be touched
up with original paint supplied in small quantity units by SIPOS Aktorik.
This list cannot cover every eventuality. Further checks may be necessary in accordance with the
plant-specicconditions.Anyimpermissibledeviationsorchangesdetectedduringinspectionmust
berectiedimmediately.
Under normal operation conditions, service or inspection of the devices is recommended every 8
years, including storage time. The following maintenance work also has to be performed:
■
Replace lubricant within gear housing,
■
Replace seals,
■
Check all parts within the direct power drive for wear,
■
Tighten screw connections of electrical connections.
Depending on the operation conditions, shorter maintenance intervals may be required
This applies in particular to actuators in high temperature version – add. version T09. They have
to be checked for proper condition by the SIPOS service every 2 years and wear parts have to be
replaced!
It is recommended that the services of the local SIPOS Aktorik service centers are utilized for this
purpose.
