16. Maintenance After commissioning, check part-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 part-turn actuators require very little maintenance.
Precondition for reliable service is correct commissioning.
Seals made of elastomers are subject to aging and must therefore regularly
be checked and, if necessary, 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 operated seldom, 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 for tightness. If required,
tighten applying the torques given in table 1, page 5.
The gear housing is filled with lubricant in the factory. This filling lasts for
several years of service.
17. Disposal and recycling
AUMA actuators have an extremely long lifetime. However, there will come a
time when you have to replace them.
Our 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.
.
See disassembled material to a sound disposal or to separate recycling
according to materials.
.
Observe the national regulations for waste disposal.
18. Service AUMA offers extensive services such as maintenance and inspection for
actuators. Addresses, AUMA offices and representatives can be found
on page 28 and on the Internet (www.auma.com).
