LK-G-M-NO0-E

CAUTION

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.
