3. Installing the Scale
3-1. Installation Precautions
3-1-1. Checking the Installation Direction
Check that the scale is installed in the positional relationship shown in Fig. 3-1.
Except when installed on a vertical axis, only the orientation in Fig. 3-1 should be used.
If installing on a machine tool or other equipment where powder and dust occur, install using the A orientation
since this allows usage of cutting fluid and prevents the intrusion of cutting dust.
Install using the B orientation only in other situations when virtually no foreign objects can enter the scale.
Fig. 3-1. Scale installation direction
Installing on vertical axis
If installing on a machine tool or other equipment where powder and dust occur, install so that the scale
slider is facing the opposite direction of the machining tool (cutting tool).
Fig. 3-2. Scale installation position and direction for the vertical axis

3-2 (E)
BL55-RU
3-1-2. Range of Movement Settings
As shown in Fig. 3-3, when the head cable is drawn out to the right side, the point where the distance from
the slider left end and scale unit left end is 28.5 mm is considered the left end movable limit. Although the
slider or scale unit can move an amount equal to the measuring length from this left end movable limit, there
is almost no margin at both ends. Be particularly careful that the machine movable length falls within the
scale measuring length.
Fig. 3-3. Operation range
The detector head will be damaged if the slider or scale unit is moved past the measuring length.
A mechanical limiting mechanism (such as a stopper) is needed for machines that exceed the measuring
length (movable range) of the scale. Be sure to install this type of device before installing the scale.
3-1-3. Protecting the Head Cable
The head cable and slider are designed to be attached and removed by screws.
Be careful not to pull strongly on the cable or repeatedly bend the cable, since this can damage it.
3-1-4. Attaching the Scale Cover
To maintain scale performance, attach a protective cover to the scale as shown in Fig. 3-4 when the scale is
directly exposed to chips and cutting fluid during use.
