Smart Positioner YT-2700L,R Installation manual
Bracket Information
YT-2700R is supplied with standard bracket which would fit to actuator stem of 20mm. For other
height of the stem, please make brackets according to the different height.
1) Attach bracketed YT-2700R to the actuator by using hexagon-headed and wrench bolts.
Size of the bracket hole is 6mm. When tightening bolts, please use spring washer or similar
for firm attachment to the actuator, so YT-2700R will not be affected by vibration or any other
impact.
2) Set rotation position of the actuator stem at zero point, “0%”. For a single type of actuator, it
is easy to check zero point, because the actuator stem is positioned at zero point when there
is no supply pressure. If double acting actuator is used, check actuator stem’s rotation
direction (clockwise or counter-clockwise) by supplying pressure.
3) Install the fork lever as shown below after setting actuator stem at zero point. Check the
direction of the actuator stem – clockwise or counter-clockwise. Installation angle of the fork
lever should be 45 degrees based on the linear shaft. For NAMUR shaft, the angle does not
matter.
4) After setting fork lever position, assemble lock nuts which are located on the bottom of the
fork lever. Make sure to set the height of upper fork lever between 6-11 mm, which is lower
than upper bracket height.
