For details on the installation method, see the later-described example installation.
• Th e rear of the scale and surface A are used as the installation guide.
• Loosely turn the mounting screws of the sensor head fi rst. Use a clearance gauge to check the clearance
with the scale and then tighten the screws with the specifi ed torque to fasten the scale. (See Fig. 3-2.)
A side (installation guide)
Be sure to observe the following to prevent the scale set from being aff ected by noise from other devices.
• When coupling relays, solenoids, motors or other devices to this scale set, be sure to keep the scale unit
and connection cable as far away from these devices as possible.
• Do not arrange the connection cable alongside or parallel to device power supply cables. Be sure to keep
the connection cable 20 cm or more away from power supply cables.
• In the event that the device power supply cable and the connection cable cross each other, do not arrange
the cables in parallel, and instead arrange the cables so that they cross at as close to a right angle as
possible.
Installation example
Example 1 (recommended): Installation when a stop surface of the scale and the sensor head is
Scale installation accuracy is improved when a stop surface is made. Th is also simplifi es reinstallation of
the scale.
1. Check and adjust the scale bracket's parallelism with respect to the machine guide, and then secure in
place.
