Safety and Maintenance • 12 Gocator 2000 Family
Environment and Lighting
Avoid strong ambient light sources
The CMOS imager used in this product is highly sensitive to ambient light; stray light may have adverse
effects on measurement. Do not operate this device near windows or lighting fixtures that could influence
the measurement. If the unit must be installed in an environment with high ambient light levels, a lighting
shield or similar device may need to be installed to prevent light from affecting measurement.
Avoid installing sensors in hazardous environments
To ensure reliable operation and to prevent damage to Gocator sensors, avoid installing the sensor in
locations;
• that are humid, dusty, or poorly ventilated
• with a high temperature, such as places exposed to direct sunlight
• where there are flammable or corrosive gases
• where the unit may be directly subjected to harsh vibration or impact
• where water, oil, or chemicals may splash onto the unit
• where static electricity is easily generated
Ensure that ambient conditions are within specifications
Gocator sensors are suitable for operation between 0 – 50 °C and 25 – 85% relative humidity (non-
condensing). Measurement error due to temperature is limited to 0.015% of full scale per degree C.
The Master 200 is similarly rated for operation between 0 - 50 °C.
Sensor Maintenance
Keep sensor windows clean
Gocator sensors are high-precision optical instruments. To ensure the highest accuracy is achieved in all
measurements, the windows on the front of the sensor should be kept clean and clear of debris.
Use care when cleaning sensor windows
Use dry, clean air to remove dust or other dirt particles. If dirt remains, clean the windows carefully with a
soft, lint-free cloth and non-streaking glass cleaner or isopropyl alcohol. Ensure that no residue is left on
the windows after cleaning.
Turn off lasers when not in use
LMI Technologies uses semiconductor lasers in 3D measurement sensors. To maximize the lifespan of
the sensor, turn off the laser when not in use.
Avoid excessive modifications to files stored on the sensor
Settings for Gocator sensors are stored in flash memory inside the sensor. Flash memory has an
expected lifetime of 100,000 writes. To maximize lifetime, avoid frequent or unnecessary write
operations.
