WARNING
♦Machine designer, installer, employer and operator
• The machine designer, installer, employer and operator are solely responsi-
ble to ensure that all applicable legal requirements relating to the installation
and the use in any application are satised and all instructions for installa-
tion and maintenance contained in the instruction manual are followed.
• Whether this device functions as intended to and systems including this de-
vice comply with safety regulations depends on the appropriateness of the
application, installation, maintenance and operation. The machine designer,
installer, employer and operator are solely responsible for these items.
• The engineer would be a person who is appropriately educated, has wide-
spread knowledge and experience, and can solve various problems which
may arise during work, such as a machine designer, or a person in charge
of installation or operation etc.
• The operator should read this instruction manual thoroughly, understand its
contents, and perform operations following the procedures described in this
manual for the correct operation of this device.
• In case this device does not perform properly, the operator should report this to
the person in charge and stop the machine operation immediately. The machine
must not be operated until correct performance of this device has been conrmed.
♦Installation
• There is the detection mount difference by directivity of a liquid leakage. When there
are a direction from which a liquid leakage happens, and an inclination, please in-
stall the nose-of-cam side (opposite side of a cable) of a sensor towards a top.
• Use the mounting bracket MS-SQ4-□ (optional) which suits the liquid to de-
tect. If selecting mounting bracket is wrong, it does not work properly.
• Periodical checking of operation is recommended with the liquids which are
not dangerous (water, alcohol, etc.).
• The amount of detection may change with the conditions of the installation surface.
• Be sure to use the mounting bracket MS-SQ4-□ (optional) when installing this device to avoid
human error, etc. Reliable detection cannot be guaranteed when this sensor is used alone.
• After installing this product, x the cable at 100mm of base of this product on oor. Use the
material which does not be effected by the chemical liquid for the xing bracket for cable.
♦Wiring
• In case dangerous operation of the system installed this product by no wir-
ing to ground is not considered , it may cause serious injure or death.
• To avoid turning the power ON by no wiring to ground, wire it to ground 0V
side when using PNP and wire it to ground +24V when using NPN.
♦Environment
• Avoid using this device in an explosive atmosphere because this product
does not have an explosive-proof protective construction.
• Do not use a mobile phone or a radio phone near this device.
• In case this device is used where electrostatic charge is present, use a
metal leak pan, which should be connected to an actual ground.
• Do not install this device in the following environments.
1) Areas exposed to intense interference (extraneous) light such as high-
frequency uorescent lamp (inverter type), rapid starter uorescent lamp,
stroboscopic lights, ash beacon lights or direct sunlight.
2) Areas with high humidity where condensation is likely to occur
3) Areas exposed to too much steam or dust. Areas exposed to corrosive or explo-
sive gases. And do not use this device where oil or grease splashes to this device
4) Areas exposed to vibration or shock of levels higher than that specied.
♦Maintenance
• When using chemical liquid, use proper protections such as groves, masks,
goggles, helmets etc. When using protections, me sure to read manuals of
them and use properly.
• Dispose or reinstall in different environment, ush with DI water.

CAUTIONS
●Make sure that the power supply is OFF while wiring. Also wrong wiring cause damage of the sensor.
●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.
●Do not use during the initial transient time (approx. 50ms) after the power supply is switched ON.
●Extension up to total 30m is possible with a 0.3mm2, or more of conductor cross-section
area cable. However, in order to reduce noise, make the wiring as short as possible.
●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.
●In case a surge is generated from power supply, take countermeasures such
as connecting a surge absorber to the origin of the surge.
●In case air bubbles are drawn into the detection part, take care that it may take
some time for detection to stabilize, or detection may even become unstable.
●When liquid or oil remains or there is scratch on the detection surface or the
attachment, It may not work properly.
