Chapter 4 Installation

4.3 Troubleshooting The Encoder

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.

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 4.4.

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.

4.4 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.

4.5 Transportation

Caution.

 When packing the unit for shipping, use the original packing. If this is not 

available, use a strong box and surround the unit with at least 100 mm of shock 

absorbent material.
