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 regu
-
larly 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.
Part-turn actuators SG 05.1 – SG 12.1 / SGR 05.1 – SGR 12.1
