Setting The Movement Range; Protection Of The Head Cable; Mounting A Protective Cover - Magnescale SR138-025R Instruction Manual

3-2-2. Setting the movement range

Mount the scale unit in the operating range shown in Fig. 3-3.
• A leeway (equivalent to 7 mm/0.28" at the left and right ends of
the scale unit for a measuring length of up to 200 mm/7.8" and
15 mm/0.59" for a measuring length of up to 250 mm/9.8") is
provided for the slider movement. Be sure not to move the
slider part beyond this limit or the scale part may be damaged.
• 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.

3-2-3. Protection of the head cable

The head cable has an integrated design with the scale unit, and
so mount the scale unit while being careful not to put pressure on
the cable. Take care not to pull the head cable forcefully or bend
it repeatedly or the cable may break.

3-2-4. Mounting a protective cover

Where the scale unit is exposed to chips and cutting fluid, provide
a protective cover shown in Fig. 3-4 to maintain high
performance of the scale unit.
