PRECAUTIONS FOR PROPER USE

NO / NC selection function [Liquid (F9) mode only]

•The NO / NC selection can be done by pressing the jog switch for

3 sec., or more, when Liquid (F9) mode ( ) has been set and MODE indicator / DISP (yellow) lights up. In case of Leak (F7)

mode ( ), the display does not change to NO / NC selection function.

For the selection method of Leak (F7) mode / Liquid (F9) mode, refer to ‘Individual teaching mode’ on p.603 or ‘Collective teaching mode’ on p.604.

	blinks.

When Jog switch is turned to the ‘’ side or ‘ ’ side, the display and MODE indicator / RUN (green) blinks,

4and NO / NC can be chosen.

: Normally closed (OFF in liquid absent condition.)

: Normally open (OFF in liquid present condition.)

When Jog switch is pressed, setting display blinks 3 times and

5is confirmed.

6The sensor returns to the step 2.

When MODE key is pressed, the sensor returns to RUN

7mode and the incident light intensity is displayed. MODE indicator / RUN (green) lights up.

The setting is complete.

Note: The initial setting at the time of factory shipment is the normal close

( ) setting.

Wiring

•Make sure that the power supply is off while wiring.

•Verify that the supply voltage variation is within the rating.

•Take care that if a voltage exceeding the rated range is applied, or if an AC power supply is directly connected, the sensor may get burnt or damaged.

•In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.

•If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.

•Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (single winding transformer) is used, this product or the power supply may get damaged.

•In case a surge is generated in the used power supply, connect a surge absorber to the supply and absorb the surge.

•Take care that short-circuit or wrong wiring of the load may burn or damage the sensor.

•Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

•Make sure to use the optional quick-connection cable for the connection of the amplifier. Extension up to total 100 m 328.084 ft is possible with 0.3 mm2, or more, cable. However, in order to reduce noise, make the wiring as short as possible.

Others

•Do not use during the initial transient time (0.5 sec. approx.) after the power supply is switched on.

•Take care that the sensor is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance.

•Avoid dust, dirt, and steam.

•When the fiber head gets dusty or dirty etc. the sensitivity deteriorates. To keep stable detection, wipe the fiber head to remove dust or dirt etc. and carry out sensitivity teaching periodically.

•This sensor is suitable for indoor use only.

•Take care that the product does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.

•This sensor cannot be used in an environment containing inflammable or explosive gases.

•Never disassemble or modify the sensor.
