4. If required, attach the spacer to the actuator shaft.
Refer to figures 2-9 and 2-10. The travel indicator
assembly can have a starting position of 7:30 or
10:30. Determine the desired starting position then
proceed with the next step. Considering the top of the
digital valve controller as the 12 o’clock position, in the
next step attach the travel indicator, so that the pin is
positioned as follows:
If increasing pressure from the digital valve
controller output A rotates the potentiometer shaft
clockwise (as viewed from the back of the
instrument), mount the travel indicator assembly such
that the arrow is in the 10:30 position, as shown in
figure 2-9.
If increasing pressure from the digital valve
controller output A rotates the potentiometer shaft
counterclockwise (as viewed from the back of the
instrument), mount the travel indicator assembly such
that the arrow is in the 7:30 position, as shown in
figure 2-10.
Note
ValveLink software and the Field
Communicator use the convention of
clockwise (figure 2-9) and
counterclockwise (figure 2-10) when
viewing the potentiometer shaft from
the back of the FIELDVUE instrument.
5. Attach the travel indicator, to the shaft connector or
spacer as described in the mounting kit instructions.
6. Attach the mounting bracket to the digital valve
controller.
7. Position the digital valve controller so that the pin
on the travel indicator engages the slot in the feedback
arm and that the bias spring loads the pin as shown in
figure 2-11. Attach the digital valve controller to the
actuator or positioner plate.
8. If a travel indicator scale is included in the
mounting kit, attach the scale as described in the
mounting kit instructions.
