9.5.2.
Running direction OPEN (white section): set
1.
Move valve in direction OPEN to desired intermediate position.
2.
If you override the tripping point inadvertently: Move valve in opposite direction
and approach intermediate position again in direction OPEN (always approach
the intermediate position in the same direction as in later electrical operation).
3.
Press down and turn setting spindle [4] with screw driver in direction of the
arrow and observe the pointer [5]: While a ratchet click is felt and heard, the
pointer [5] moves 90° every time.
4.
If the pointer [5] is 90° from mark [6]: Continue turning slowly.
5.
If the pointer [5] moves to mark [6]: Stop turning and release setting spindle.
➥
The intermediate position setting in running direction OPEN is complete.
6.
If you override the tripping point inadvertently (ratchet click is heard after the
pointer has snapped): Continue turning the setting spindle in the same direction
and repeat setting process.
9.6.
Test run
Perform test run only once all settings previously described have been performed.
9.6.1.
Direction of rotation: check
Valve damage due to incorrect direction of rotation!
→
If the direction of rotation is wrong, switch off immediately.
→
Correct phase sequence.
→
Repeat test run.
1.
Move actuator manually to intermediate position or to sufficient distance from
end position.
2.
Switch on actuator in direction CLOSE and observe the direction of rotation on
the indicator disc.
→
Switch off before reaching the end position.
➥
The direction of rotation is correct if actuator runs in direction CLOSE and
indicator disc turns counterclockwise.
9.6.2.
Limit switching: check
1.
Move actuator manually into both end positions of the valve.
➥
The limit switching is set correctly if:
-
LSC switch trips in end position CLOSED
-
LSO switch trips in end position OPEN
-
the switches release the contacts after turning back the handwheel
2.
If the end position setting is incorrect: Reset limit switching.
