Maintenance
After commissioning, check multi-turn actuator for damage to paint finish.
Do a thorough touch-up to prevent corrosion. Original paint in small quantities
can be supplied by AUMA.
AUMA multi-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 fastened 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 multi-turn actuator and valve/gearbox for tightness. If
required, tighten applying the torques given in table 1, page 11.
.
For multi-turn actuators with output drive type A: At intervals of approx. 6
months from commissioning, press in Lithium soap EP multi-purpose
grease on mineral oil base at the grease nipple with grease gun (quantity
see table 2, page 12).
27.
Lubrication
.
The gear housing is filled with lubricant in the factory.
.
A grease change is recommended after the following operation time:
.
If rarely operated, after 10 – 12 years.
.
If operated frequently, after 6 – 8 years.
Lubrication of the valve stem must be done separately.
28.
Disposal and recycling
AUMA actuators have an extremely long lifetime. However, they have to be
replaced at one point in time.
The actuators have a modular design and may therefore easily be disas-
sembled, separated, and sorted according to materials, i.e.:
.
electronic scrap
.
various metals
.
plastics
.
greases and oils
The following generally applies:
.
Collect greases and oils during disassembly. As a rule, these substances
are hazardous to water and must not be released into the environment.
.
Arrange for controlled waste disposal of the disassembled material or for
separate recycling according to materials.
.
Observe the national regulations for waste disposal.

AUMA offers extensive services such as maintenance and inspection for
actuators as well as various training courses. Addresses of AUMA offices
and representatives can be found on page 60 and on the Internet
