Gocator Light Bar
You can use one or two light bars in a Gocator system to provide light for a Gocator 205 color
module. The Gocator 205 color module can provide power to both light bars. Light bars are
connected using a light bar to Gocator 205 cordset.
One light bar can be mounted on the Gocator 205 color module using optional mounting hardware.

Laser Safety
The light emitted from these devices has been set in accordance with IEC60825. However,
staring into the beam, whether directly or indirectly, must be avoided. IEC60825 classifies laser
products into three different categories depending on light emitted, wavelength and eye safety.
This product is designated for use solely as a component and as such it does not fully comply

Gocator 200 Series and Light Bar Quick Start Guide 6
with the standards relating to laser products specified in U.S. FDA CFR Title 21 part 1040 and IEC
60825-1.
CLASS 3B LASER PRODUCT
LASER RADIATION
AVOID EXPOSURE TO THE BEAM
The full laser safety details including precautions, responsibilities and requirements are stated in the
Gocator user manual. Use of controls or adjustments or performing procedures other than those
specified in the user manual may result in hazardous radiation exposure.
Electrical Safety
Failure to adhere to the guidelines described in this section may result in electrical shock or
equipment damage.
Minimize voltage potential between system ground (ground reference for I/O signals) and
sensor ground
Use shielded cables with shield grounded at both ends. Sensor housing should be connected to
earth ground.
Use a suitable power supply
The +24-48V power supply used with Gocator sensors should be an isolated supply with inrush
current protection.
Use care when handling powered devices

Gocator 200 Series and Light Bar Quick Start Guide 7
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.
Grounding Gocator
Gocator housings should be grounded to the earth and the grounding shield of the Gocator I/O
cordsets. Gocator sensors are designed to provide adequate grounding through the M4 screws.
Always check grounding with a multi-meter to ensure electrical continuity between the mounting
frame and the Gocator connectors.
The frame or electrical cabinet that the Gocator is mounted to must be connected to earth ground.
Grounding Cordset (Recommended)
To minimize interference with other equipment, the Power & Ethernet or the Power & Ethernet to
Master cordset (depending on cordset used in system) can be grounded by terminating the cordset
shield before the split. The most effective grounding method is to use a 360-degree clamp. For
instructions, see the user manual.
Installation
1. Mounting
Mounting the Gocator is recommended before applying power. Ensure that a proper earth
ground is established and that a heat sink is properly installed before applying power.
AGocator multi-point scanner is mounted through three holes on the device's back plate. For the
appropriate screw diameter, pitch, and length, and bolt hole diameter, see the dimension drawings
in the user manual.
Scanners can be mounted with either M8 or 5/16" hardware. Provision to adjust the position and
orientation of the sensor to align its laser plane with the laser planes of other sensors, above and
beside, is highly recommended. This alignment is critical to prevent sensor crosstalk and ensure true
differential measurements; aligned laser planes also provide a better appearance to the end user of
the system.
Scanners should not be installed near objects that might occlude a camera's view of the projected
light.
Scanners should not be installed near surfaces that might create unanticipated light reflections.

Gocator 200 Series and Light Bar Quick Start Guide 8
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. The temperature of all of its components must 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 within the sensor.
To prevent accidental laser light exposure, in multi-sensor systems, attach light shields between
scanners. For hole positions, see the scanner specification drawings. (LMIdoes not supply light
shields.)
2. Assembling a Sensor +Camera +Light Bar System
AGocator multi-point scanner can optionally be used in conjunction with a camera module and one
or two light bars. The camera module is mounted to three holes on the front of the scanner. Light
bars in turn are mounted to the camera module using optional mounting hardware.
The following shows how a Gocator 205 and a light bar mount to a Gocator 200 series scanner.
Light bar to Gocator 205 mounting hardware is optional.

Gocator 200 Series and Light Bar Quick Start Guide 9
As with standalone sensors, systems should not be installed near surfaces that might occlude a
camera's view of the projected light (laser or white light) or surfaces that might create unanticipated
light reflections. For full details, see the envelope drawing for your sensor in the specification
drawings.
To prevent accidental laser light exposure, in multi-sensor systems, attach light shields between
scanners. For light shield hole positions and specifications, see the scanner specification
drawings. (LMIdoes not supply light shields.)
3. Connecting Gocator to a Host Computer
Standalone System
Standalone systems are typically used when only a single sensor is required. The device can be
connected to a computer's Ethernet port for setup and can also be connected to devices such as
encoders, photocells, or PLCs. Standalone systems are not typically used in wood applications.

Gocator 200 Series and Light Bar Quick Start Guide 10
Dual- / Multi-Sensor System
A Master network controller (excluding Master 100) can be used to connect two or more sensors into
a multi-sensor system. 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
400/800/810/1200/2400/2410 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).
Multi-sensor Gocator 200 systems can only be configured using GoSDK. For more information, see
GoSDK and GoWebScanSDK in the Gocator 200 Series user manual.
