12.1. Preventive measures for servicing and safe operation
The following actions are required to ensure safe device operation:
6 months after commissioning and then once a year
●
Carry out visual inspection:
Check cable entries, cable glands, blanking plugs, etc. for correct tightness and
sealing.
Consider torques according to manufacturer's details.
●
Check fastening screws between actuator and gearbox/valve for tightness. If
required, fasten screws while applying the tightening torques as indicated in
chapter <Assembly>.
●
When rarely operated: Perform test run.
For enclosure protection IP68
After submersion:
●
Check actuator.
●
In case of ingress of water, locate leaks and repair. Dry device correctly and
check for proper function.
12.2. 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.
12.3. Disposal and recycling
Our 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 sep-
arate recycling according to materials.
