Maintenance
Lubrication
●
In the factory, the gear housing is filled with grease.
●
Grease change is performed during maintenance
-
Generally after 4 to 6 years for modulating duty.
-
Generally after 6 to 8 years if operated frequently (open-close duty).
-
Generally after 10 to 12 years if operated rarely (open-close duty).
●
We recommend exchanging the seals when changing the grease.
●
No additional lubrication of the gear housing is required during operation.
Notes regarding the
maintenance
●
Check actuator visually. Ensure that no outside damage or changes are visible.
●
The electric connection cables must be without damage and wired correctly.
●
Thoroughly touch up any possible damage to painting to prevent corrosion.
Original paint in small quantities can be supplied by AUMA.
●
Cable entries, cable glands, plugs etc. have to be checked for correct tightness
and sealing. Consider torques according to manufacturer's details. If required,
replace the components. Only use components which are approved for use in
hazardous locations.
●
Check whether Ex connections are fastened correctly.
●
Take care of possible discoloration of the terminals and wires. This would indi-
cate an increased temperature.
●
For Ex housings, pay special attention to a possible collection of water. This
may originate from condensation due to severe temperature variations (e. g.
change of night and day), from damaged seals etc. Remove any water immedi-
ately.
●
Check the flame path gaps of flameproof enclosures for dirt and corrosion.
●
Since the dimensions of all flameproof joints are strictly defined and inspected,
no mechanical work (such as grinding) shall be performed on them. The
flameproof joints should be cleaned suitably.
●
Prior to fitting, preserve joint surfaces with an acid-free corrosion protection
agent (e. g. Esso Rust-BAN 397).
●
Ensure that all housing covers are handled carefully and that the seals are
checked.
●
All cable and motor protection components have to be checked.
●
If defects impairing the safety are detected during maintenance, repair measures
have to be initiated without delay.
●
Any kind of surface coating for the flameproof joints is not permitted.
●
When exchanging parts, seals etc. only original spare parts shall be used.
12.4.
Disposal and recycling
AUMA devices have a long lifetime. However, they have to be replaced at one point
in time. The devices have a modular design and may, therefore, easily be separated
and sorted according to materials used, i.e.:
●
electronic scrap
●
various metals
●
plastics
●
greases and oils
The following generally applies:
●
Greases and oils are hazardous to water and must not be released into the
environment.
●
Arrange for controlled waste disposal of the disassembled material or for sepa-
rate recycling according to materials.
●
Observe the national regulations for waste disposal.
