Notational Conventions
This guide uses the following notational conventions:
Follow these safety guidelines to avoid potential injury or property damage.
Consider this information in order to make best use of the product.

Gocator 2300 & 2880 Series 11
Safety and Maintenance
The following sections describe the safe use and maintenance of Gocator sensors.
Laser Safety
Gocator sensors contain
semiconductor lasers that emit visible
or invisible light and are designated as
Class 2M, Class 3R, or Class 3B,
depending on the chosen laser option.
See Laser Classes on the next page for
more information on the laser classes
used in Gocator sensors.
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.
Use of controls or adjustments or performance of procedures other than those specified herein
may result in hazardous radiation exposure.

Laser Classes
Class 2M laser components
Class 2M laser components would not cause
permanent damage to the eye under
reasonably foreseeable conditions of operation,
provided that exposure is terminated by the
blink reflex (assumed to take 0.25 seconds).
Because classification assumes the blink reflex,
the wavelength of light must be in the visible
range (400 nm to 700 nm). The Maximum
Permissible Exposure (MPE) for visible radiation
for 0.25 seconds is 25 watts per square meter,
which is equivalent to 1 mW entering an
aperture of 7 mm diameter (the assumed size of
the pupil).
Class 3R laser components
Class 3R laser products emit radiation where
direct intrabeam viewing is potentially
hazardous, but the risk is lower with 3R lasers
than for 3B lasers. Fewer manufacturing
requirements and control measures for 3R laser
users apply than for 3B lasers.
Class 3B laser components
Class 3B components are unsafe for eye
exposure. Usually only ocular protection will be
required. Diffuse reflections are safe if viewed
for less than 10 seconds.
Labels reprinted here are examples only. For accurate specifications, refer to the label on your
sensor.
Precautions and Responsibilities
Precautions specified in IEC 60825-1 and FDA CFR Title 21 Part 1040 are as follows:

*LMI Class 3B laser components do not incorporate these laser safety items. These items must be added and completed by customers
in their system design.
Class 3B Responsibilities
LMI Technologies has filed reports with the FDA to assist customers in achieving certification of laser
products. These reports can be referenced by an accession number, provided upon request. Detailed
descriptions of the safety items that must be added to the system design are listed below.
Remote Interlock
A remote interlock connection must be present in Class 3B laser systems. This permits remote switches
to be attached in serial with the keylock switch on the controls. The deactivation of any remote switches
must prevent power from being supplied to any lasers.
Key Control
A key operated master control to the lasers is required that prevents any power from being supplied to
the lasers while in the OFF position. The key can be removed in the OFF position but the switch must not
allow the key to be removed from the lock while in the ON position.
Power-On Delays
A delay circuit is required that illuminates warning indicators for a short period of time before supplying
power to the lasers.
Beam Attenuators
A permanently attached method of preventing human access to laser radiation other than switches,
power connectors or key control must be employed. On some LMI laser sensors, the beam attenuator is

Gocator 2300 & 2880 Series Safety and Maintenance • Laser Safety • 14
supplied with the sensor as an integrated mechanical shutter.
Emission Indicator
It is required that the controls that operate the sensors incorporate a visible or audible indicator when
power is applied and the lasers are operating. If the distance between the sensor and controls is more
than 2 meters, or mounting of sensors intervenes with observation of these indicators, then a second
power-on indicator should be mounted at some readily-observable position. When mounting the
warning indicators, it is important not to mount them in a location that would require human exposure
to the laser emissions. User must ensure that the emission indicator, if supplied by OEM, is visible when
viewed through protective eyewear.
Warning Signs
Laser warning signs must be located in the vicinity of the sensor such that they will be readily observed.
Examples of laser warning signs are as follows:
FDA warning sign example IEC warning sign example
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 shows example calculations of the NOHDvalues for each Gocator model and laser
class, assuming continuous operation of the laser. As a configurable device the Gocator allows the user
to 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 table therefore shows the worst-case NOHD.

To calculate the NOHDvalue for a specific laser class, use the following formula:
NOHD= Model Constant / MPE
Model Constant includes a consideration of the fan angle for the individual models.
Systems Sold or Used in the USA
Systems that incorporate laser components or laser products manufactured by LMI Technologies
require certification by the FDA.
Customers are responsible for achieving and maintaining this certification.
Customers are advised to obtain the information booklet Regulations for the Administration and
Enforcement of the Radiation Control for Health and Safety Act of 1968: HHS Publication FDA 88-8035.
This publication, containing the full details of laser safety requirements, can be obtained directly from
the FDA, or downloaded from their web site at http://www.fda.gov/cdrh.
Electrical Safety
Failure to follow the guidelines described in this section may result in electrical shock or
equipment damage.

Gocator 2300 & 2880 Series Safety and Maintenance • Environment and Lighting • 16
Sensors should be connected to earth ground
All sensors should be connected to earth ground through their housing. All sensors 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.
See Gocator 2300 &2880 I/O Connector on page 409 for a description of connector pins used with
Gocator 2300 series sensors.
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.
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
lthat are humid, dusty, or poorly ventilated;
lwith a high temperature, such as places exposed to direct sunlight;
lwhere there are flammable or corrosive gases;
lwhere the unit may be directly subjected to harsh vibration or impact;
lwhere water, oil, or chemicals may splash onto the unit;
lwhere 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 400/800/1200/2400 is similarly rated for operation between 0–50° C.

The storage temperature is -30–70° C.
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.
Gocator sensors are high-accuracy devices, and the temperature of all of its components must
therefore be in equilibrium. When the sensor is powered up, a warm-up time of at least one
hour is required to reach a consistent spread of temperature in the sensor.
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 file save
operations.

Getting Started
The following sections provide system and hardware overviews, in addition to installation and setup
procedures.
System Overview
Gocator sensors can be installed and used in a variety of scenarios. Sensors can be connected as
standalone devices, dual-sensor systems, or multi-sensor systems.
Standalone System
Standalone systems are typically used when only a single Gocator sensor is required. The sensor can be
connected to a computer's Ethernet port for setup and can also be connected to devices such as
encoders, photocells, or PLCs.
Dual-Sensor System
In a dual-sensor system, two Gocator sensors work together to perform profiling and output the
combined results. The controlling sensor is referred to as the Main sensor, and the other sensor is
referred to as the Buddy sensor. Gocator's software recognizes three installation orientations: Opposite,
Wide, and Reverse.

A Master 400/800/1200/2400 must be used to connect two sensors in a dual-sensor system. Gocator
Power and Ethernet to Master cordsets are used to connect sensors to the Master.
Multi-Sensor System
Master 400/800/1200/2400 networking hardware can be used to connect two or more sensors into a
multi-sensor system. Gocator Master cordsets are used to connect the sensors to a Master. The Master
provides a single point of connection for power, safety, encoder, and digital inputs. A Master
400/800/1200/2400 can be used to ensure that the scan timing is precisely synchronized across
sensors. Sensors and client computers communicate viaan Ethernet switch (1 Gigabit/s recommended).
Master 400/800/1200/2400 networking hardware does not support digital, serial, or analog output.
