electromagnetic wave interference from other equipment.
1. Do not pass lead and connection cables through the same ducts as power lines.
2. Be sure to install the unit at least 0.5 m (20") or more away from high voltage or large
current sources or high-power relays.
3. Absolutely do not bring the unit near magnets or sources of electromagnetic waves.
Note
•Magnet chucks and other sources of magnetic force of approx. 600×10–4T (600 G)
should be kept at least 50 mm (2") or more away from the side surfaces and 100 mm (4")
or more away from the opening surfaces of the scale's steel chassis.
•If the unit must be installed close to sources of magnetic force, be sure to implement
adequate electromagnetic shielding countermeasures.
Installation place precautions
1. Mount the scale for more precise positioning as closely as possible to the workpiece or to
the object being measured.
(The farther the scale is mounted from workpiece, the greater the mechanical errors grow.)
2. The scale unit should be used within an ambient temperature range of 0 to 40°C. Avoid
locations where the scale is exposed to direct sunlight and heat sources such as motors.
3. Do not place anything on the mounted scale, or step on it: excessive force to the scale
causes trouble.
4. Never install the scale in locations such as places where the scale could be exposed
directly to coolant liquid or to coolant in mist form.

3-1-2. Setting the operating range
•The measuring length of the scale is the distance between the
measuring length marks (D) at both ends of the scale.
•Mount the scale in such a position that the slider center moves
within these measuring length marks.
•A leeway (10 mm (0.39") on the left and right) is provided for
the slider movement. Take special care not to move the slider
beyond this limit or the scale may be damaged.
3-1-3. Protection of the head cable
The head cable and scale come as a single integrated unit. Take
care not to pull the head cable forcefully or bend it repeatedly or
the cable may break.
3-1-4. Mounting a protective cover
If the scale is mounted in a location where it may be exposed
directly to chips or cutting oil, it is recommended that a protective
cover such as the one shown in Fig. 3-4 be installed so that the
scale is not exposed to the outside as far as possible. This will
help to maintain the scale's performance.
Slider center
Measuring length mark
Mount the scale so that the slider center moves within this range.
(Effective movement range)
Fig. 3-4 Example of protective cover
Fig. 3-3 Operating range
•Mechanical limiting devices (stoppers, etc.) are required for
sliders which move in excess of the effective movement range
of the scale unit. In these cases, be sure to take the appropriate
measures before mounting the scale unit.

3-3. Mounting Procedure
Precautions
The procedures for mounting the scale unit are described below.
For the scale unit, the only disassembly process during the
mounting work is removing the slider holder. (See “3-4-3”.) Do
not disassemble other locations.
The scale unit is comprised of precision mechanical and
electromagnetic parts, so applying excessive force will have a
large effect on the unit's performance and service life. Therefore,
take care not to apply excessive force when mounting the scale
unit.
In addition, when carrying the unit, the scale body and slider
should be held together. Take care not to carry the scale by the
head cable or interface unit.

3-4-1. Mounting of scale
〈1〉When the mounting surface already meets
parallelism and flatness requirements
When the scale mounting surface is finished and meets the
parallelism and flatness specifications below, just mount the
scale. (For scales of L < 1250 mm (49"), use two M4 x10 hex
socket head cap screws and two plain washers (M); for scales of
L >1250 mm (49"), use three M4 x10 hex socket head cap
screws and three plain washers (M). Tightening torque: 350
N.cm/35 kgf.cm)
Flatness of A, B surfaces
Parallelism of A, B surfaces to
machine table movement
Provide the range shown in Fig. 3-5 for surface A.
The above tolerances suppose no quick change in the surfaces
and no obstacle in the way between the right and left mounting
surfaces.
〈2〉When the scale mounting surface is a casting
surface
Mount the scale using mounting brackets
(1) When the scale mounting surface is a casting
surface and parallelism is not satisfied
Use mounting brackets and adjust so that the parallelism
specified in 〈1〉may be satisfied.
Fig. 3-6 Length of mounting brackets and measurement
of their parallelism
Shorter than the machine table stroke
Mounting bracket
Mounting brackets are only necessary at the left and right
foot areas of the scale. They do not need to extend the entire
length of the scale. However, if it is not possible to measure
the parallelism of the left and right feet due to the movable
length of the mounted unit, it will be necessary to make
longer mounting brackets.
within 0.15 mm (0.006")

English
10 (E)
SJ700A
(2) Checking of mounting position and tapping
Check that the parallelism for mounting scale meets the
specifications, and then tap for M4 screws of 10 mm (0.39")
depth referring to the Dimensions on page 19.
(3) Mounting of scale
Mount the scale loosely with M4 x10 hex socket head cap
screws and plain washers (M), and leave it for 30 minutes for
the scale to reach ambient temperature. Then firmly mount
the scale.
(4) Measuring parallelism of scale with machine table
movement
Place a dial gauge directly where the alignment mark (Fig.
3-7 1in the figure below) is positioned on the side of the
scale, and check that the scale is surely mounted parallel to
the machine table movement.
Adjust the parallelism of the length between the two alignment
marks to within 0.15 mm (0.006") and tighten the setscrews. For
the scale with a measuring length of 1250 (49.21") or more,
adjust the parallelisms of the lengths between the alignment mark
and those on both sides of it to within 0.15 mm (0.006").
Note
Since alignment marks are not provided on scales with a
measuring length of 250 mm (9.8") or less, place the dial gauge
on the scale unit and ensure that the allowance at the two ends of
the machine travel is within 0.15 mm (0.006").

3-4-2. Mounting of the slider
(1) When parallelism and flatness of the mounting
surface are already satisfied
When the mounting surface is finished and its parallelism
and flatness satisfy the specifications below, just mount the
slider using two M4 x14 hex socket head cap screws and
two plain washers (S).
The mounting dimensions differ depending on the clearance
between the Band Csurfaces.

•If clearance between B and C surfaces is set to
between 8.7 and 8.9 mm
Move the machine table till the mounting surface comes just at
the slider. First use the spacers provided to fill the gap between the
mounting surface and slider, and then secure the slider. Then
remove the screws which fix slider holder. (If the gap is still not
filled, check the gap between the Band Csurfaces and adjust it
is necessary.)

9 mm (0.35") ±0.1 mm (0.004")
(5) When the specified parallelism for the scale
mounting bracket is not obtained
Insert spacers below the feet and make adjustment by placing
a dial gauge at 2in Fig. 3-7 to adjust the parallelism to within
0.15 mm (0.006") throughout the length between may be
obtained at the alignment marks.
For scales equipped with a center foot plate (effective length
1,250 to 1,600 mm (49.21 to 62.99 inch)), make sure that the
parallelism near the center foot plate is also within 0.15 mm
(0.006").

English

SJ700A
(2) When the slider mounting surface has yet to meet
the specifications
When the mounting surface of the machine is a casting
surface, use a bracket. Place the bracket on the underside of
the slider without loosening the screws that hold the slider
holder. Adjust the position of the bracket and mount it with
the supplied M4 x14 bolts.

Remove the two screws securing the scale and the slider holder
and move the slider by hand to align it with the brackets.
Secure the slider in place in the position where the protruding
portion (D) of the slider holder comes into contact with the
scale. Finally, remove the slider holder from the slider.
Note
Attempting to move the bracket side when the slider holder is
secured could cause the brackets to strike the slider. Therefore,
always move only the slider side.
