Protective measures
1.1.6
The end user or the contractor is responsible for implementing required protective
measures on site, such as enclosures, barriers, or personal protective equipment for the staff.
Maintenance
1.1.7
Auma India multi-turn actuators require very little maintenance but they
need to be tested regularly for its correct functioning. After commissioning, check
actuator for damage to paint finish. Do a thorough touch-up to prevent corrosion. Correct
commissioning is a prerequisite for reliable service. Seals made of elastomers are
subject to aging and must therefore regularly be checked and, if necessary, exchanged.
It is also very important that the O-rings at the covers are placed correctly and cable
glands fastened firmly to prevent ingress of dust or water.
We recommend additionally:
If operated seldom, perform a test run about every 6 months. This ensures that the
actuator is always ready to operate. The version of actuators discussed in this manual
have an option for
Partial Valve Stroke Test (PVST)
to check if the actuator is healthy.
Approximately six months after commissioning and then every year check bolts
between part-turn actuator and valve for tightness. If required, tighten applying
appropriate torques.
The gear housing is filled with lubricant in the factory. This filling lasts for several years
of service.
Corrosions of paint damage parts must be prevented through touch up.
Any device modification requires the consent of the manufacturer.
