Thank you very much for using SUNX products.
Please read this Instruction Manual carefully and
thoroughly for the correct and optimum use of
this product. Kindly keep this manual in a conve­nient place for quick reference.

If this product is used as a sensing de-

Ɣ

vice for personnel protection, serious
body injury or death could result.

Never use this product as a sensing device

Ɣ

with any press machine, shearing machine,
roll grinding machine, forming machine, vul­canizer, or robot etc. for protection of a hand
or a part of the body.
This product does not include a self-check-

Ɣ

ing circuit for safety functions necessary
to allow its use as a safety device. Thus, a
system failure or malfunction can result in
either an energized or a de-energized output
condition.
When this product is used as a sensing

Ɣ

device in the following applications and if a
problem relating to “law” or “product liability”
occurs, SUNX shall not be liable for the fail­ure and for the damage or less.

1) Use of this product installed to a machin­ery or a device as a sensing device to
detect a hand or a part of the operator’s
body entering a dangerous area and stop
the machinery or the device.

2) Installation of this product to a protection
device for preventing to enter a dangerous
area and use of this as a sensing device
which detects a hand or a part of the op­erator’s body and open / close the door or
window.

3) Use of this product as a sensing device for
personnel protection (including interlock).

For sensing devices to be used as safety

Ɣ

devices for press machines or for person­nel protection, use products which meet
standards, such as OSHA, ANSI or IEC etc.,
for personnel protection applicable in each
region or country.
In case of using as a safety device for press

Ɣ

machine, use a product approved by the
Ministry of Health, Labor and Welfare in Ja­pan.

Output (Note)

1. Place the emitter and the receiver face to face
along a straight line.

2. After the cables have been correctly connected,
switch the power ON.

3. Move the emitter in the up, down, left and right
directions, in order to determine the range of
the beam received condition with the help of the
operation indicator (red) on the receiver. Then,
set the emitter at the center of this range.

4. Similarly, adjust for up, down, left and right an­gular movement of the emitter.

5. Further, perform the angular adjustment for the
receiver also.

6. Check that the stable incident beam indicator
(green) lights up.

7. Interrupt each beam channel with the actual

CAUTIONS

This product has been developed / produced for

Ɣ

industrial use only.
Make sure that the power supply is off while wir-

Ɣ

ing and operation of the selection switch.
Take care that wrong wiring may damage the sensor.

Ɣ

Verify that the supply voltage variation is within

Ɣ

the rating.
If power is supplied from a commercial switch-

Ɣ

ing 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 (0.5

Ɣ

sec.) after the power supply is switched on.
In case noise generating equipment (switching

Ɣ

regulator, inverter motor, etc.) is used in the vicin­ity of the sensor, connect the frame ground (F.G.)
terminal of the equipment to an actual ground.
Extension up to total 100m is possible with

Ɣ

2

0.3mm

, or more, cable for both emitter and re­ceiver. However, in order to reduce noise, make
the wiring as short as possible.
Do not run the wires together with high-voltage lines

Ɣ

or power lines or put them in the same raceway.
This can cause malfunction due to induction.
Take care that the sensor is not directly exposed

Ɣ

high frequency lighting device or sunlight etc.,
as it may affect the sensing performance.
Avoid dust, dirt, and steam.

Ɣ

Take care that the product does not come in

Ɣ

contact with water, oil, grease, organic solvents,
such as thinner, etc., strong acid or alkaline.
Make sure to use an isolation transformer for

Ɣ

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

Ɣ

supply, connect a surge absorber to the supply
and absorb the surge.
The emitter and the receiver must face each

Ɣ

other correctly. If they are set upside down, the
sensor does not work.
