Safety and Maintenance
Laser Safety
The Gocator 2490 sensor used in the Legal for Trade system contains a semiconductor
laser that emits visible light. It is designated as Class 2.
Gocator sensors are referred to as components, indicating that they are sold only to
qualified customers for incorporation into their own equipment. These sensors do not
incorporate safety items that the customer may be required to provide in their own
equipment (e.g., remote interlocks, key control; refer to the references below for detailed
information). As such, these sensors do not fully comply with the standards relating to laser
products specified in IEC 60825-1 and FDA CFR Title 21 Part 1040.
Class 2 laser components are considered to be safe, provided that:
●The user’s blink reflex can terminate exposure (in under 0.25 seconds).
●Users do not need to look repeatedly at the beam or reflected light.
●Exposure is only accidental.

Nominal Ocular Hazard Distance (NOHD)
Nominal Ocular Hazard Distance (NOHD) is the distance from the source at which the
intensity or the energy per surface unit becomes lower than the Maximum Permissible
Exposure (MPE) on the cornea and on the skin.
The laser beam is considered dangerous if the operator is closer to the source
than the NOHD.
The following table provides the NOHD values for the Gocator 2490 sensor model used in
the Legal for Trade system, assuming continuous operation of the laser. As a configurable
device, a sensor lets you set the laser exposure (laser on-time) independently of the frame
period (total cycle time for data acquisition). Continuous operation of the laser means that
the laser exposure is configured to be identical to the frame period, which is also referred
to as 100% duty cycle. However, in many applications the laser exposure can be smaller
than the frame period (less than 100% duty cycle), thereby reducing the NOHD. The tables
therefore show the worst-case NOHD.

Electrical Safety
Failure to follow the guidelines described in this section may result in electrical
shock or equipment damage.
Sensors should be connected to earth ground
All sensors should be connected to earth ground through their housing or connector cable
shielding. Sensors not grounded using the cable shield, should be mounted on an earth
grounded frame using electrically conductive hardware to ensure the housing of the sensor
is connected to earth ground. Use a multi-meter to check the continuity between the
sensor connector and earth ground to ensure a proper connection.
Minimize voltage potential between system ground and sensor ground
Care should be taken to minimize the voltage potential between system ground (ground
reference for I/O signals) and sensor ground. This voltage potential can be determined by
measuring the voltage 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.
Use a suitable power supply
The power supply used with sensors should be an isolated supply with inrush current
protection or be able to handle a high capacitive load. Verify the voltage input
requirements for your sensor in the sensor's specifications.
Handling, Cleaning, and Maintenance
NOTE: 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.

Environment and Lighting
Avoid strong ambient light sources
The imager used in this product is highly sensitive to ambient light. Do not operate this
device near windows or lighting fixtures that could influence measurement or data
acquisition. 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 sensors, avoid installing the sensor
in locations
●that are humid, dusty, or poorly ventilated (for more information, see below);
●with a high temperature, such as places exposed to direct sunlight (for more
information, see below);
●where there are flammable or corrosive gasses;
●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 operating and storage conditions are within specifications
The sensor's operating temperature is 0 to 40 °C.
For all sensors, the storage temperature is -30 to 70 °C.
For all sensors, relative humidity (non-condensing) is 25% to 85%.
The sensor must be heat-sunk through the frame it is mounted to. When a
sensor is properly heat sunk, the difference between ambient temperature and
the temperature reported in the sensor's health channel is less than 15 °C.
