13.1. 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:
Cable entries, cable glands, blanking plugs, etc. have to be checked for correct
fit and sealing. If required, tighten cable glands and blanking plugs with torque
in compliance with the manufacturer's specifications.
Check actuator for damage as well as for grease or oil leakage.
●
When deployed in areas where dust formation represents a potential explosion
hazard, perform visual inspection for deposit of dirt or dust on a regular basis.
Clean devices if required.
●
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.
13.2. Maintenance
Manual operation
During maintenance, the mechanical parts of the handwheel activation, in particular
motor coupling and retaining spring, must be checked. Replace the parts in case of
visible wear.
Lubrication
●
In the factory, the gear housing is filled with grease.
●
Additional lubrication of the gear housing is not required during operation.
●
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 infrequently (open-close duty).
●
We recommend replacing the seals when changing the grease.
13.3. 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
