Thru-Bolt™ Mounting
1. Attach mounting plate to actuator using fasteners
and lockwashers provided.
2. Loosen indicator cover set-screw.
2a. Rotate indicator cover to desired viewing angle and
retighten set-screw. (Make sure indicator cover is
pushed all the way into housing slot.)
3. Rotate coupling spacer and indicator drum to
desired position. (OPEN or CLOSED appearing
through indicator window)
4. Remove spacer screw and fit torque coupling or
Namur coupling onto coupling spacer. Separate
spacer and indicator drum and rotate spacer to align
coupling with actuator shaft. Fit coupling spacer
over indicator drum drive hub.
4a. Secure torque coupling assembly or Namur coupling
with screw of proper length. (Additional coupling
spacers and longer screw may be required on some
mountings.)
5. Slide Thru-Bolts with washers into housing and fit
retaining quad-rings over bolts to retain them.
5a. Top of actuator shaft should be within 1/4"
(6.35mm) from coupling screw head or Namur
coupler.
5b. Torque coupler or Namur coupler must be fully
engaged in slot and be centered on the shaft or
block attached to the shaft.
6. Operate actuator to full open and full closed
positions and check for proper alignment between
switch and actuator. Eccentricity of shaft must
be no greater than .01" (.254mm) from
centerline. The torque coupler or Namur coupler
must be centered on the flats of the actuator shaft or
block in both the full open and full closed position.
Realign as necessary and final tighten Thru-Bolts.
7. "Fine-tune" visual indicator cover repeating #2 and
lightly tighten set screw.
