LNR502E Encoded Long Travel, Linear Stage with Stepper Motor Actuator
4.3.1 SmartSignal Electronics Module
Fig. 4.7 Dimensions – SmartSignal electronics module
4.4 Troubleshooting
The green Power/Calibration indicator will not come on.
Ensure that the SmartSignal electronics’ 15-pin D-sub connector is fully seated and connected.
The green, ‘Proper Alignment’ indicator doesn't stay illuminated over the full length of travel, the red or yellow indicators may
be lit.
Verify that the mid point of the actuator travel has been correctly aligned to the midpoint of the stage travel.
Ensure that the encoder scales are clean over their entire length - see Section 4.6.
The green Power/Calibration indicator is flashing.
The ‘SmartSignal electronics’ Index/Calibration process is activated by pressing the recessed button in the SmartSignal
electronics’ connector body. When this button is pressed, the Power/Calibration LED will flash until the internal sensor passes
over the midpoint of the stage at least once in each direction.
If after performing the above checks the problem persists, the unit should be returned to the factory for investigation.
4.5 Preventive Maintenance
4.6 Cleaning
To ensure trouble free operation, periodic cleaning of the encoder scales is advised. Frequency depends upon usage and
environment.
1) Invert the stage, and push the moving platform to one end of its travel. Part of the encoder scale is now accessible.
2) Blow off any loose particles with an aerosol air duster. Pay particular attention to the unexposed portion of the scale.
3) Move the platform to its opposite end of travel and repeat item (2).
4) If problems persist, the scale may be cleaned with an optical wipe, dampened with isopropyl alcohol or acetone. Use only
products described as ‘suitable for cleaning optical components’. These can be obtained from stockists such as RS
Components. Do not scrub the scale.
