11.3. 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, re-
place the components. Only use components which are approved for use in haz-
ardous locations.
●
Check whether Ex connections are fastened correctly.
●
Take care of possible discoloration of the terminals and wires.This would indicate
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 immediately.
●
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.
11.4. 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 environ-
ment.
●
Arrange for controlled waste disposal of the disassembled material or for separate
recycling according to materials.
●
Observe the national regulations for waste disposal.
