2.0 DSXSV9 suggested Layout Installation
1. The servo arm moves the drive-wire through the turnout throw-bar hole
using an approx 1/2" access clearance hole or slot through the layout base
material, centered under the throw-bar drive hole. Use base-template below.
2. Pass the free end of the drive-wire through the access hole and then through
the throw-bar center hole. There will be excess drive-wire tip to trim later.
3. Align the servo mount so that the drive-wire will move in the throw-bar ac-
tuation direction. Set mount orientation so Thrown/ Clockwise horn rotation
will drive the throw-bar to the diverging or Thrown turnout direction .
4.
Use two 5/16" long mount screws to hold the unit when in the correct posi
-
tion. There are mount slots for up to 4 mounting screws and the slots allow
some fine position and orientation adjustments using screw pairs.
5. Connect the servo to a DS78V and drive to Thrown and Closed positions and
observe the turnout throw-bar moves as needed.
6. In the Thrown or Closed position, using eye protection, carefully trim the
drive-wire tip just below the rail tops, so as not to catch on any rolling stock.
7. With the drive-wire using the outermost horn arm hole, there will be about
+/- 0.25" of travel at a throw-bar offset of about 1" from the servo mount.
This will be fine for most HO and N scale turnouts and layout base material
depths. Any excess drive angle using the 0.6mm wire will provide com-
pliance and some spring tension on the rails. The heavier 0.8mm wire will
provide even more spring pressure, and not be required in most cases.
8. Always ensure at extreme T/C angles that the
horn arm
does not bind to
make servo jam ON. This may damage servo and is not covered under war
-
ranty.
These steps are some of many possible methods to install the DSXSV9, and user
skills will allow many variations of these broad steps.
