Full Stroke Adjustment Setting
NOTE:
Standard actuators or actuators with the Full Stroke Adjustment option are shipped by
default with a rotation setting of 90° +/-0.5°.
The stroke adjustment setting procedure can be two steps:
1.
Setting the Full Stroke Adjustment screw to the 90° (factory) poisiton.
—
This step can be applicable if a standard actuator needs to be converted
with a Full Stroke Adjustment end cap kit or if the position of the Full
Stroke Adjustment screw is somehow lost.
2.
Setting the Full Stroke Adjustment screw to the required angle.
C.3.1
Factory Setting Procedure
1.
In order to set the Full Stroke Adjustment Screws accurately to the outward position:
—
Do not change the setting of the DSA limit stop screws (A and B) located
above the air connection interface.
—
Move the pistons of the actuator outwards by applying pressure to the
A-port.
2.
Screw in both the Full Stroke Adjustment Screws (41) until the screws touch the
pistons. You will feel an obstruction.
Important:
Do not overtighten the screws.

Notes:
1.
Only the outward stroke can be adjusted with the Full Stroke Adjustment screws.
—
In case of assembly code CW, the left side limit stop (A) is redundant.
—
In case of assembly code CC, the right side limit stop (B) is redundant.
2.
For the inward stroke the standard limit stops can be used:
—
The right side limit stop (B) for assembly code CW
—
The left side limit stop (A) for assembly code CC
