In this article, we’re going to discuss how to mount a remanufactured Fisher DVC6000 series positioner on an actuator.
This example explains the process using a remanufactured Fisher 667 size 30.
Step 1
The first step is positioning the mounting hardware. The main components you’ll be working with are the adjustment arm, connector arm, lock nut, and star washer.
Start by having one of your bolts halfway screwed into the yoke. That way, you can accurately line up your bracket. As you slide the bracket into position, keep the connector arm on top of the bias spring.
When you have the bracket positioned, thread the other bolt into the yoke and tighten both bolts.
Step 2
The second step is adjusting the travel.
First, retrieve the alignment pin from inside the cover.
- Remove the four captivated screws
- Remove the cover. There, you will find the alignment pin.
The alignment pin will hold the feedback arm in position as you adjust for its travel. Say for example you have an actuator with a 3/4″ travel. In this case, you’d adjust the feedback arm to line up with the connector arm shaft at the .75 mark while using the alignment pin to align hole “A” with the threaded hole in the housing.
Once the feedback arm is secure, tighten the nut to maintain its position and return the alignment pin.
Step 3
Next, connect the actuator output to the DVC.
Step 4
After that, apply slight pressure and move on to auto calibration.
