between Analog_out- and system ground. The maximum permissible voltage potential is 12 V but should
be kept below 10 V to avoid damage to the serial and encoder connections.
For a description of the connector pins, see Gocator I/O Connector on page 620.
Use a suitable power supply
The +24 to +48 VDC power supply used with Gocator sensors should be an isolated supply with inrush
current protection or be able to handle a high capacitive load.
Use care when handling powered devices
Wires connecting to the sensor should not be handled while the sensor is powered. Doing so may cause
electrical shock to the user or damage to the equipment.
Handling, Cleaning, and Maintenance
Dirty or damaged sensor windows (emitter or camera) can affect accuracy. Use caution when
handling the sensor or cleaning the sensor's windows.
Keep sensor windows clean
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 Gocator 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 file save
operations.
Environment and Lighting
Avoid strong ambient light sources
The imager used in this product is highly sensitive to ambient light hence stray light may have adverse
effects on measurement. Do not operate this device near windows or lighting fixtures that could
influence 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
l that are humid, dusty, or poorly ventilated;
l with a high temperature, such as places exposed to direct sunlight;
l where there are flammable or corrosive gases;
l where the unit may be directly subjected to harsh vibration or impact;
