Electro-Pneumatic Positioners
5) After setting fork lever position, lock nuts which are assembled on the bottom of the fork lever.
Make sure to set upper height of the fork lever between 6-11mm, which is lower than upper
bracket height. <Figure 8>

6) Attach YT-1000R to the bracket. Fix the clamping pin on the main shaft's center of U-EPR and
insert connection bar into the fork lever slot, so it can be locked to the fork lever spring. This
sets the alignment of the main shaft of U-EPR and center of the actuator stem.
Bad alignment of the main shaft and the actuator stem lowers U-EPR
s durability, because too much force will be on the main shaft of U-EPR.

7) Tighten U-EPR base and the bracket with hexagon-headed bolts and plate washer.
It is
recommended to tighten four bolts after checking U-EPR 's position. <Figure 10>
