INSTALLATION CONDITIONS
a. The place where the scale is to be installed should be thoroughly cleaned from oil, dust, coolant,
and burrs etc.
b. Appropriate reader head mounting brackets will need to be designed to fix the reader head making sure
that the reader head can freely move along the magnetic scale.
c. Mount the scale so that the magnetic strip on the extrusion will be to the top side of the extrusion.
INSTALLATION
The magnetic scale (open extrusion) measures the movement precisely and accurately. To ensure
the specified accuracies, installation of the magnetic scale (open extrusion) must be done correctly as
de-scribed in this manual. Please read this manual carefully before use of the products.
Mounting Bracket
Connecting Bracket
Magnetic scale installation:
1. Select the mounting surface for the scale on the machine insuring that the reader head also can be
mounted in such a way to be able to travel along the length of the scale. The surface should be as flat as
possible and run parallel with the axis. Whilst there is adjustment on the brackets this is limited and still
may require packing.
2 Drill and Tap Holes:
a) Select the mounting brackets required and confirm the location of threaded holes needed to hold the
brackets to the machine. The brackets should be attached so that the scale is supported every 900 -
1000mm. Insure that the connecting brackets are also mounted so that they are in a position to connect the
extruded lengths.
b) Drill and tap M5 threaded holes on the machine surface to suit each of the brackets.
3. Mount the Scale
a) Install the scale in the mounting brackets and connecting brackets on the machine surface and secure
with the lock blocks so that the scale is secure.
b) Once the scale is installed in the mounting plates on the machine surface, using a dial indicator ad-
just the scale so that it sits in the correct location, square and in line with the axis. Adjustment screws
are mounted in each of the brackets
(c) Once the aluminium extrusion has been secured to the
mounting blocks, and is aligned, clean the aluminium so that it is
dry and free from dirt and oils. Lay the magnetic tape (sticky
face down ) in the groove in the extrusion, carefully removing the
backing paper as magnetic strip is attached to the extrusion. The
strip must sit evenly in the groove provided.
(d) Once the magnetic strip is in place, slide the metal protec-
tive strip into the grooves provided so that it covers the magnetic
strip..
(e) Attach the end caps to the two ends of the scale so that the
metal cover strip is secured..
The Reader Head Installation
1:Select the appropriate reader head mounting surface
a) Mount the reader head securely on a suitable mounting surface that will hold the reader head rigid and
secure, parallel with the magnetic strip
b) Insure that the gap between the reader head and the tape is between 0.5~1.2mm for the full length of
the scale
d) Connect the signal line of the reader head to the corresponding location on the DRO making sure that
the cable is clear of any moving parts.
