3.2 Mounting Remote Positioner on a Rotary Actuator (Models 4235 & 4335)
Step 1. Mount bracket and inner beacon coupler to actuator as described in Section 3.1 Step 1.
Step 2. Press fit the inner beacon to the inner beacon coupler. The inner beacon needs to be prop-
erly oriented. Use the symbols on the top of the inner beacon to mount as shown in Condition 1 or
Condition 2. (See Figure 3-3). Condition 1 and Condition 2 show the placement of the inner beacon
with respect to the position sensor housing while the actuator is in the fail position.
Step 3. Mount the position sensor to the bracket. As stated in Step 2 make sure that the position
sensor is mounted in a fashion that properly orients it with respect to the inner beacon.
