responsible to ensure that all applicable legal requirements relating to

the installation and the use in any application are satised and all in-

structions for installation and maintenance contained in the instruction

manual are followed.

●Whether this device functions as intended to and systems includ-

ing this device 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.

widespread knowledge and experience, and can solve various prob-

lems which may arise during work, such as a machine designer, or a

person in charge of installation or operation etc.

♦Operator

●The operator should read this instruction manual thoroughly, under-

stand 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 perfor-

mance of this device has been conrmed.

♦Environment

●Do not use a mobile phone or a radio phone near this device.

●If there exists a reflective surface in the place where this device is

to be installed, make sure to install this device so that reected light

from the reflective surface does not enter into the receiver, or take

countermeasures such as painting, masking, roughening, or changing

the material of the reective surface, etc. Failure to do so may cause

the device not to detect, resulting in death or serious injury.

●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 uo-

rescent lamp, stroboscopic lights or direct sunlight.

2) Areas with high humidity where condensation is likely to occur

3) Areas exposed to corrosive or explosive gases

Areas exposed to vibration or shock of levels higher than that specied

5) Areas exposed to contact with water

6) Areas exposed to too much steam or dust

Introduction

♦Installation

●Always keep the correctly calculated safety distance between this de-

vice and the dangerous parts of the machine.

●Install extra protection structure around the machine so that the op-

erator must pass through the sensing area of this device to reach the

dangerous parts of the machine.

●Install this device such that some part of the operator’s body always

remains in the sensing area when operator is done with the danger-

ous parts of the machine.

●Do not install this device at a location where it can be affected by wall

reection.

●When installing this device in multiple sets, install the sets so that

mutual interference does not occur. For details, refer to “2-3-3 Device

Placement ” and “3-4 Interference Prevention Function.”

● Do not use any reection type or recursive reection type arrangement.

♦Equipment in which this device is installed

●When this device is used in the “PSDI Mode,” an appropriate control

circuit must be congured between this device and the machinery. For

details, refer to the standards or regulations applicable in each region

or country.

●In Japan, do not use this device as safety equipment for a press machine.

●Do not install this device with a machine whose operation cannot be

stopped immediately in the middle of an operation cycle by an emer-

gency stop equipment.

●This device starts the performance after 2 seconds from the power

ON. Have the control system started to function with this timing.

Introduction

♦Wiring

●Be sure to carry out the wiring in the power supply OFF condition.

●All electrical wiring should conform to the regional electrical regula-

tions and laws. The wiring should be done by engineer(s) having the

special electrical knowledge.

●Do not run the sensor cable together with high-voltage lines or power

lines or put them together in the same raceway.

●In case of extending the cable of ST4-A□, use the exclusive cable.

Total cable length of ST4-A□ should be 50m or less (emitter and

receiver, respectively).

For details, refer to “2-3-4 When Connecting

Multiple Units of Single-beam Sensor ST4-A□.”

●Do not control the device only at one control output (OSSD 1 / 2).

●In order that the output is not turned ON due to earth fault of control

output (OSSD 1 / 2) terminal, be sure to ground to 0V side (PNP out-

put) / 24V side (NPN output).

♦Maintenance

●When replacement parts are required, always use only genuine sup-

plied replacement parts. If substitute parts from another manufacturer

are used, the device may not come to detect, resulting in death or

serious injury.

●The periodical inspection of this device must be performed by an en-

gineer having the special knowledge.

●After maintenance or adjustment, and before starting operation, test

this device following the procedure specied in “Chapter 4 Mainte-

nance.”

●Clean this device with a clean cloth. Do not use any volatile chemi-

cals.

♦Others

●Never modify this device. Modication may cause the device not to

detect, resulting in death or serious injury.

● Do not use this device to detect objects ying over the sensing area.

●Do not use this device to detect transparent objects, translucent ob-

jects or objects smaller than the specied minimum sensing objects.
