1. Work surface
To get the highest level of precision from the tracer, we recommend that you lay out it on a strong surface that is and flat, stable
isolated from any shocks or oscillations.
The tracer can be placed up to 5 meters from your computer and/or your edger. Optional longer cords are available.
2. Environment
The temperature and the relative humidity of the location where you use your tracer must be within the following limits:
Operation in “remote lens edging”
+15°C (+59°F) to +30°C (+86°F)
30% to 75%
Operation in “local edging”
+10°C (+50°F) to +40°C (+104°F)
30% to 75%
Storage
-5°C (+23°F) to +50°C (+122°F)
10% to 95%
Altitude < 2000 m
Avoid abrupt changes of temperature and moisture and install the tracer:
in an area not exposed to direct sunlight,
away from any heat sources,
away from any strong magnetic fields,
away from any corrosive chemical products or vapors and liquids.
Make sure to arrange it so it can expel heat from the top of the tracer. Do not put any objects on the tracer.
This machine is not suitable for nor intended to operate in an environment classified as being under risk of explosion.
3. Electrical installation
a. Electrical characteristics
Tracer power
12 Volts
Power supply voltage (external power)
100-240 VAC
Frequencies 50 - 60 Hz
Grounding
The tracer must be plugged into a grounded electrical network.
This grounding must be in conformity and checked by an electrician.
Parasites and micro-interruptions
The tracer was designed to resist and function in spite of the presence of parasites and the possibility of micro-interruptions on the
electrical communication.
However, if these defects are major and abnormal, the normal functioning of the product cannot be guaranteed.
