Linear Actuator
The FY500 can be mounted in any orientation. The mounting parts kit for the linear actuator
contains a mounting bracket with NAMUR/IEC 60534-6-1 standard mounting patterns. Applicable to
actuators with cast yoke (with rib or plane surface design), or pillar yoke for U-bolt application.
WARNING
In case of a pneumatic or electrical failure, it is important to know the behavior of the
actuator. Before mounting the positioner on an actuator, the failsafe position and
direction of rotation of the actuator drive shaft should be verified.
The connection between the actuator stem and feedback arm is typically made using a slotted
bracket and a feedback pin. There are two ways to transfer the motion through the feedback pin, the
traditional mounting method, and the alternate mounting method .
The Traditional Method
The feedback pin is fixed in the slotted bracket and rides inside the feedback arm.
WARNING
Before starting any assembly or disassembly of the actuator/positioner set, the electrical
supply and pneumatic supply must be removed. The actuator line must also be emptied.
Stay away from moving parts to avoid serious injury.
1. Attach the feedback pin to the slotted bracket with two M6x1 hex nuts, and two flat washers.
Leave the hex nut loose for later adjustment. See figure 1.8.

2. Attach slotted bracket to the actuator stem with two M6x1 screws, two lock washers, and two flat
washers, but do not tighten the fasteners because fine adjustment is required. See figure 1.8.
3. If required, a mounting adaptor is included in the mounting kit. Attach the mounting adaptor to the
actuator stem so that the mounting adaptor extends through the yoke leg, then attach the slotted
bracket to the adaptor, as shown in figure 1.9. The feedback pin must be on the opposite side of the
stem.
