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.
