If the four screws [1] are fastened: Unfasten the screws [1] with approx. 3 turns.
2.
Move valve to end position OPEN with handwheel. Check whether end stop
nut [2] rotates simultaneously.
→
Otherwise: Turn end stop nut [2] counterclockwise until end stop.
3.
In case end position OPEN has been passed: Turn back the handwheel by
several turns and approach end position OPEN again.
4.
Turn end stop nut [2] clockwise by 1/8
th
turn.
Information: In this process, the protective cap [3] must not be unfastened.
➥
Thus, the end stop OPEN within the part-turn actuator is set to a slightly higher
swing angle (approx. 1°) than the valve end position.
5.
Fasten screws [1] crosswise at 25 Nm.
●
Subsequent to this setting, the limit switching for end position OPEN can
be set (refer to <Limit switching: set> chapter). For this, the switch com-
partment must be opened and the indicator disc removed (refer to <Switch
compartment: open> chapter).
●
In general, the end stop CLOSED does not require setting due to the fact
that the swing angle was already set in the factory.
9.3
Swing angle
The swing angle must only be changed if the swivel range for end stop setting is not
sufficient.
The swing angle set in the factory is indicated on the name plate.
In the standard version the swing angle can be adjusted within the range of 80° to
110°. Optional swivel ranges: refer to technical data pertaining to the order.
