Servicing and maintenance
Damage caused by inappropriate maintenance!
→
Servicing and maintenance must be carried out exclusively by suitably qualified
personnel having been authorised by the end user or the contractor of the plant.
We recommend contacting our service for any interventions.
→
Only perform servicing and maintenance tasks when the device is switched off.

The following actions are at least required to ensure safe device function during
operation:
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.
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
tightness and sealing. If required, tighten cable glands and blanking plugs with
torque in compliance with the manufacturer's specifications.
●
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.
Seals
Preventive actions to ensure the IP protection degree. The seals of seal kit S1 should
be replaced within a period of 4 – 8 years:
After 4 years: In case of outdoor installation (frequent changes of temperature and
humidity, extreme weathers)
After 8 years: In case of indoor installation (constant or virtually constant
environmental conditions)
If original AUMA screw plugs are used, original AUMA seals must also be used.
They are included with the AUMA seal kit S1. The seal kit can be ordered with AUMA.
Lubrication
●
Within the device lifetime, no additional lubrication of the gear housing is required
during operation.
Lifetime
The maximum lifetime depends on the number of operating cycles or the number of
starts (refer to technical data) as well as the respectively applicable AUMA load
profiles. Distinction is made between actuators in open-close or modulating duty:
Open-close duty
(OPEN/CLOSE)
The load is measured by means of the number of operating cycles at a defined torque
characteristics, the AUMA load profile.
An operating cycle corresponds to an angular stroke of 90° in both directions (e.g.
OPEN - CLOSE - OPEN).
AUMA load profile:
10 % of the travel at 100 % of maximum torque.
