3-2. Head Installation
The detection sensor is built into head where it is
marked with “
∇
”. Install the head so that the “
∇
”
mark is always within the measuring length of the
scale.
•
To fasten the head, insert the accessory spacer
between the detection surface of the head and the
scale, and install with the accessory screws (M4
×
20).
•
After installing the head, remove the spacer.
•
Tightening torque should be 0.7 N·m (7 kg·cm) to
1.1 N·m (11 kg·cm).
•
After installing the head, use the accessory cable
clamps to fasten the cable where it extends from
the head. Make sure the cable is not loose.
•
The relative positions of the scale and head should
be as shown in Fig. 3-2.
