The following actions are at least required to ensure safe device function during
operation:
Maintenance specifications for Ex certified products
●
Maintenance interventions must be performed in compliance with IEC 60079-
17. The standard defines the intervals and test depths for the mandatory tests.
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.
●
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.
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)
Only screw plugs approved for the protection type may be used which also ensure
the required IP protection. Type of protection and IP protection and indicated on the
name plate.
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.
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:
