Reference
Provides advanced and useful information for operation.
•At startup and during operation, be sure to monitor the functions and performance of the LK-G Series.
•We recommend that you take substantial safety measures to avoid any damage in the event of a problem occurring.
•Do not attempt to open or modify the LK-G Series or use it in any way other than as described in the specifications. If the LK-G Series is modified or used other than as described, the warranty will be voided.
•When the LK-G Series is used in combination with other devices, functions and performance may be degraded, depending on the operating conditions and surrounding environment.
•Do not use the LK-G Series for the purpose of protecting the human body.
•Do not allow the temperature to change sharply around the LK-G Series, including the accessories. Otherwise, condensation may lead to malfunction.
Follow the safety precautions below to ensure safe operation
•Apply the correct power voltage. Failure to do so may cause fire, electric shock, or malfunction.
•Do not attempt to disassemble or modify the unit. Doing so may cause fire or electric shock.
Handling abnormalities
Turn off the power immediately in the following cases. Using the unit in an abnormal condition could cause fire, electric shock, or accident.
Contact the nearest KEYENCE office for repair.
•If liquid including water, chemicals or debris enters the unit.
•If the unit is dropped or the case is damaged.
•If abnormal smoke or odor is present.

Follow the safety precautions below to ensure safe operation
•Be sure to turn the power off when you plug/unplug the cable that leads to the unit and its accessories. Not following this caution may result in damage.
•Do not turn off the power while setting items. The data being set or all the data may be lost.
•Do not block the vent holes on the unit. Increase of internal temperature may cause failure.
Installation environment
To use the LK-G Series correctly and safely, avoid installing it in the following locations; doing so may lead to breakdown of the unit.
•Location that is humid, dusty or poorly ventilated
•Location with a high temperature such as a place exposed to direct sunlight
•Location where there are flammable or corrosive gases
•Location where the unit may be directly subjected to vibration or impact
•Location where water, oil or chemicals may splash onto the unit
•Location where static electricity is easily generated
Corrective action for noise
Do not install the LK-G Series near a power source or high-voltage cable, otherwise noise may cause the LK-G Series to malfunction. Take corrective action for noise by using noise filters, laying cables separately, and/or installing insulation on the controller and the measuring unit. Use the single core shielded cable for the analog output cable.
Influence of ambient temperature
A change in the ambient temperature may cause the measurement to fluctuate. Be sure to keep it stabilized. When the ambient temperature changes by 10 °C, it takes 60 minutes for the distribution of internal temperature to equalize.
Operating ambient light intensity level
Do not use the LK-G Series near a lighting system that repeatedly and rapidly turns on and off. If it is unavoidable to use the unit in such a place, install a light shielding board or the like so that the light will not affect the measurement.
Warming up
Before using the LK-G Series, wait approximately 30 minutes after the power is turned on. Otherwise, the measured value may gradually fluctuate because the circuit is not immediately stable after the power is turned on.

LK-G-M-NO0-E |
Influence of dust or dirt
The measurement may fluctuate due to dirt, dust or fluid such as water or oil in the following cases:
•Adhesion on the protection glass: Blow the dirt off with clean air. If dirt persists, wipe the glass surface gently using a soft cloth moistened with alcohol.
•Adhesion on the surface of the measuring target: Blow the dirt off with clean air or wipe it off.
•Intrusion of floating or sprinkled dust or dirt into the light-axis range: In this case, take corrective action with a protective cover or air purge.
Influence of vibration
When the measuring target is vibrating, the measured value may fluctuate. In this case, increase the average number of times of measurement to achieve a more accurate value.
Measuring target
The measured value may fluctuate if the shapes or surfaces of the measuring targets vary. In this case, use a known target and perform appropriate correction using the calibration function.
Handling
Do not wipe with a wet cloth, benzene, or thinner. Doing so may change the color or shape of the unit. If the unit has much dirt on it, wipe it off with a cloth moistened with a mild detergent, then wipe with a soft dry cloth.
Effect of atmospheric motions
Slow atmospheric motions may affect the measurement and result in fluctuation of the measured value. In such a case, take the following countermeasures.
•Enclose the measurement portion with an appropriate enclosure.
•Agitate the air between the measurement portion and the workpiece more strongly with a fan.
The LK-G Series conforms to the EMC Directive subject to the conditions that the following requirements are satisfied. In order to use this equipment in the EU countries, be sure that the following requirements have already been satisfied beforehand.
The applicable standards are explained below.

EMI: EN61326, class A EMS: EN61326
Length of the power cord that is connected to the Controller, and length of all input/output cords must be limited to shorter than 30 m.
Part of the circuits between the inputs and output are internal common. Make sure that a potential difference does not occur between internal common terminals due to a potential difference between wires or external devices. Otherwise, it may cause malfunctions in the unit or external devices.
Examples of Wiring
LK-G3001V/LK-G3001(NPN type)
24 VDC (-), COM OUT (output COM), and COM IN (input COM) are all common via a choke coil. Also, COM OUT and COM IN of the expansion connector are common via a choke coil.

If a voltage potential difference occurs, use the unit with insulation on the LK-G power supply and the I/O terminals other than RS-232C and USB.
Precautions for a Positive Grounding Environment
When using a positive grounding environment, watch out for shorts through the COM terminal.

Precautions when connecting to computers or other external devices
When working in a positive grounding environment, when the LK-G is connected to a computer through USB in order to use LK-Navigator or when establishing RS-232C communication with a computer, take precautions to avoid shorts in between the SG (GND) terminals for the computer and the LK-G.
24 VDC (-), SG (GND) of USB, and SG (GND) of RS-232C are all common via a choke coil. Make sure that a voltage potential difference does not occur with external devices such as computers or PLC. If a voltage potential difference occurs, use with insulation on the LK-G power supply and the I/O terminals other than RS-232C and USB.

Cautions on class 3a/3R/3A laser products
Observe the following instructions. Otherwise, injury to the human body (eyes and skin) may result.
•Do not direct the laser beam at other persons.
•Never look at the laser beam through optical instruments such as a microscope, magnifier or telescope.
•Make the laser path as short as possible and be sure to terminate the laser path with a diffusion reflector or diffusion absorber so that the laser beam does not diffuse. (It is recommended to install the protection enclosure.)
•Install the laser product so that the laser beam be located well above or below eye level.
•Install the laser product carefully so that the laser beam is not unitentionally directed at mirrorlike surfaces.
•It is recommended to wear protective eye goggles.
•Do not disassemble the LK-G Series.
•Do not look directly at the laser beam.
