Compatibility • With the LS series, the controller and scanning head are calibrated as a
pair. To satisfy the specifications, therefore, be sure to combine a control-
ler and scanning head having the same serial number.
• The transmitter and receiver are also calibrated as a pair.
• When using 2 scanning heads, connect them respectively to the specified
connector port of the controller.
CHAPTER 7 Hints on Correct Use
Operating Environment • Be sure to operate the LS controller in a place where the temperature is
within a range between 0 and 45°C. (0 to 40°C for LS-3036/3060)
• Fluctuation in ambient temperature may cause measurement error.
Always maintain the ambient temperature at a constant level. If the
ambient temperature changes by 10°C, it takes approx. 60 minutes for the
temperature distribution in the LS controller to become uniform.
• Be sure to keep the laser emitting surface (transmitter) and the laser
receiving surface (receiver) free from any substance refracting light (such
as water or oil).
• Blow off dirt or dust on the protective glass using clean air. If dirt or dust
still remains, wipe it off using a soft cloth moistened with alcohol.
• The protective glass can be replaced. See the figure below to replace the
glass.
Countermeasures against
Noise • Do not mount the scanning head to the place where a certain level of
electrical noise is applied or transferred. Isolate the scanning head if
electrical noise may be occured. Otherwise, laser diode may deteriorate
or become damaged.
• Keep the wiring or connection cable away from high-voltage lines or
power lines to prevent the LS controller from malfunctioning because of
noise.
• Be sure to earth-ground the LS controller through the earth ground termi-
nal (No. 19). Insulating the scanning head is also effective in reducing
noise.
Fuse When the fuse is blown, replace it with the following one:
Midget fuse: F-7142 2A or equivalent
Cooling Fan Do not block the cooling fan on the back panel. Blocking it will overheat the
LS controller, causing malfunction.
