Before Installation - Magnescale SR67A-AZ Serie Bedienungsanleitung

• Use a scale installation bracket, where applicable, having length covering the entire scale length. Th e
parallelism of the scale may be harmed if only using a bracket divided for the installation section.

Before installation

• Check that the alignment of the installation surface (or installation brackets) is within the standards.
(For the standards, see the later-described illustration of the Installation example)
• Remove off the coating around the tap hole to ground the scale unit using the installation surface
contact with the scale.
For details on the installation method, see the later-described example installation.
• Th e rear of the scale is used as the installation guide. Th e head holders are used for securing the scale
head when transporting the head holders and cannot therefore be used as an installation guide.
• Loosely turn the mounting screws fi rst. Determine the alignment and then tighten the screws to fasten
the scale. (See Fig. 3-3)
Scale: M6 × 35 (9 N
• In environments where coolant can splash directly on the scale unit, be sure to mount a cover on the
scale unit to protect the scale unit from splashing.
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 a device power supply cable and the connection cable cross each other, arrange the
cables so they cross at as close to a right angle as possible.
