LINKING WITH LEVERS
• POSITIONING THE VOS2T-R SECURELY
The output accuracy of the VOS2T-R is largely affected by
its mechanical position relative to the actuator.
The VOS2T-R and the actuator respectively must positioned
so that the distance between the centers of VOS2T-R shaft
and the actuator stem (A – C) be equal to the length of the
actuator lever (B – D) as in Figure 2.
The length of actuator lever for the VOLK can be adjusted.
Refer to the “ADJUSTMENT PROCEDURE” section.

• CONNECTING THE VOS2T-R SIDE LEVER
Connect the lever to the VOS2T-R unit with a screw in-
cluded in the package, with a plain washer and a toothed
washer between them as in Figure 1. At this stage, you do
not have to fasten the screw tightly.
• CONNECTING THE VOS2T-R SIDE LEVER
TO THE ACTUATOR SIDE LEVER
(with the actuator side lever provided by the customer)
Attach the connecting pin to the VOS2T-R side lever utiliz-
ing the nailed nut and the nut as in Figure 3. The actuator
side lever should be threaded with the connecting pin but
left loose. The nail could be positioned in either side of the
lever, however it is limited to one side at the extreme end of
the lever hole.

LINKING WITHOUT LEVERS
Refer to Figure 5 below when the VOS2T-R is to be connect-
ed directly to an actuator without utilizing levers. Adjust
the relative positions of the actuator stem and VOS2T-R
shaft so that their center positions are in a straight line, or
otherwise use a coupling which can absorb position slides.
Note that performance of the VOS2T-R mounted in this way
is more easily affected by vibration. We recommend not to
use this method when severe vibration is observed.
