Setting of Mechanical position indicator
The two dials have a slip clutch for easy adjustment. At valve fully closed, turn dial (CLOSED)
till the arrow is in alignment with the mark on the show glass. Operate valve into fully OPEN
position and adjust dial marked (OPEN) till the arrow mark is in alignment with the mark on
the cover.
Note: The dial (CLOSED) must be held in position while adjusting dial (OPEN). (fig. 22).
Maintenance and service tasks may only be performed by authorised personnel who have
been trained on functional safety (refer to chapter 5).
Once maintenance and service tasks have been finished, the functional test must be
completed by a validating process of the safety function including at least the tests described
in
the
<Safety
equipment:
check>
and
<Proof
test
(verification
of
safe
actuator
function)>
chapters.
In case a fault is detected during maintenance, this must be reported to AUMA India Private
Limited.
AUMA actuators prioritize motor operation to manual operation. This means that the actuator
automatically switches to motor operation if requested. However, we recommend activating
motor operation after any maintenance and service interventions.
1. Immediately after start-up: Ensure sealing faces at cover and housing are clean. Check
whether O-ring is correctly in position and apply a thin film of non-acid grease. Replace
the cover and fasten with 4 screws (fig. 21).
2. Fasten control cover screws and tighten glands at conduit entries.
