Application & Installation Guide for Linear Scale (VER1.0 )

Preface the operation and maintenance

of linear scale

Requirements of the Working Conditions

1. Do not use the device in an atmosphere charged with

inflammable gases. Do not use it in the condition with

metal powder, oil, water or dust.

2. Do not disclose it in the bitter sunshine or high

temperature. the ambient working temperature should

range from 0℃~~40℃.

3. Be far away from the strong acid and alkali as well as the

chemicals.

4. Keep the signal cable of the linear scale far from the

power cords as possible.

5. Take the way of installation into consideration when

using the device in the situations of high voltage, strong

current or magnetic field. do well in isolating the

haphazard signals and avoid the disturbance of such.

Rational possesses the authority of explaining the instruction.

Rational won’t specially inform the user of the instruction.

Please contact the dealer if you have any trouble.

Other Requirements

I. Offer a proper match between the installation interface and

the electric signal interface when designing and applying the

device.

II. Do not lay heavy blocks on the signal cable. Please bundleand

fix the excessive signal cable if it is overlong and do en -sure

the workers and the equipment a favorable working path.

III. Make sure that the plugs of the signal cable are well and stabl

-y plugged onto the corresponding interface.

IV. Design the application of the linear scale according to its effe

-ctive travel range, and avoid the occurrence of surpassing the

effective range and the damage of the device.

V. Do not let dust pile up on the linear scale and the read-head or

the track of the moveable body of the linear scale.

VI. Be sure to turn off the power before unplugging the connecter

of the signal cable.

Daily Maintenance

I. Check the device after uncovering the package. Please imm

-ediately contact the dealer as soon as possible if the compone

-nts are not complete or the malfunction needs settling. Do

not disassemble or modify it at your wishes.

II. Do not clean the dust on or around the read-head and the

moveable body with forced strength or air, for it may result in

the dust dropping in the interior of the moveable body.

I. Warranty

In normal cases, the linear scale is guaranteed one year’s repair

since it was sold.

1. Principle and application

This linear scale is a kind of transmission amplitude grating, and the princ

-iple is, when the opposite travel main grating and the subordinate grating

occurs, the Moire grid/line is generated. This change will be transferred into

electric signal through the precise photo-electric exchanger, and then the digi

-tal signal at the relative travel is output after it is processed by the signal

processing circuit.

This product can be grated with Digital Readout and form a grating measu

-ring system and perform precise and accurate travel measurement. In additi

-ional, it can be applied in the trades of processing and measuring:

Equipment for processing: Lathe, Miller, Grinder and Electric dis-

charge machine.

Instrument for measuring: Profile projector, Video measuring instrument,

Tool maker microscope and so on.
