22. Maintenance After maintenance, check part-turn actuator for damage to paint finish. If
damage to paint-finish has occurred after mounting, it has to be touched up to
avoid corrosion. Original paint in small quantities can be supplied by AUMA.
AUMA part-turn actuators require very little maintenance.
Precondition for reliable service is correct commissioning.
Seals made of elastomers are subject to ageing and must therefore regularly be
checked and, if necessary, be exchanged.
It is also very important that the O-rings at the covers are placed correctly and
cable glands tightened firmly to prevent ingress of dirt or water.
We recommend additionally:
.
If rarely operated, perform a test run about every 6 months. This ensures that
the actuator is always ready to operate.
.
Approximately six months after commissioning and then every year check
bolts between part-turn actuator and valve/gearbox for tightness. If required,
tighten applying the torques given in table 1, page 9.
23. Lubrication AUMA part-turn actuators are filled with grease for lifetime.
A change of grease or re-lubrication is not necessary.
