PRECAUTIONS FOR SAFE USE

Please observe the following precautions for safe use of the product:

1. Do not use the product in environments where it can be exposed to
inammable/explosive gas.

2. Do not disassemble, repair or modify this product.

3. Be sure to make sure that locking mechanisms are locked before use.

4. The supply voltage must be within the rated range.

5. Use the power supply within the rated load.

6. Dispose of this product as industrial waste.

PRECAUTIONS FOR CORRECT USE

1. Do not install the product in locations subjected to the following conditions:

・ Direct sunlight or near heaters
・ Condensation caused by high humidity
・ Sudden changes in humidity
・ Cold conditions that may cause freezing
・ Presence of corrosive or ammable gases
・ Direct vibration or shock
・ Build-up of dust or metal chips
・ Spraying by organic solvents, water, oil or other liquids
・ Strong magnetic or electric eld
・

Reection of intense light (such as other laser beams or electric arc-welding machines)

2. Power Supply and Wiring

・ Reverse connection of power supply is not allowed. Connection to AC power supply

is also not allowed.

・ Open-collector outputs should not be short-circuited.
・ Use the Extension Cable ZG2-XC□□CR: length 25m/15m/8m/3m for extending

the cable between the Sensor Head and Sensor Controller. The total length differs
according to the Extension cable.

・ High-voltage lines and power lines must be wired separately from this product.

Wiring them together or placing them in the same duct may cause induction,
resulting in malfunction or damage.

・ When using a commercially available switching regulator, make sure that the FG

(Frame Ground) terminal is grounded.

・ If surge currents are present in the power lines, connect surge absorbers that suit the

operating environment.

・ Before connecting/disconnecting the Sensor Head, make sure that the Sensor

Controller is turned OFF. The Sensor Controller may break down if it is connected
or disconnected while the power is ON.

・ Use only the specied combinations of Sensor Head and Sensor Controller.

3. Orientation when Installing the Sensor Controller
To improve heat radiation, install the Sensor Controller only in the orientation show

below.

Correct

Do not install the Sensor Controller in the following orientations.

IncorrectIncorrect

4. Cleaning

・ Do not use paint thinner, benzene, acetone or kerosene to clean the Sensor

Controller. Doing so will melt the surface of the Sensor Controller.

・ Use commercially available alcohol.

■Communication with a Host Device

Before communicating with a host device, make sure that the product has started up.
Also, clear the receive buffers on the device in use or perform other measures since
undetermined signals might be output from the host interface when this product is
started up.

This connects the 24 V DC (±10%) power supply. When using a Sensor
Controller with a PNP output, the power supply terminal is also the common I/O
terminal for all I/O except for the Analog output.

・

Supply power from a DC power supply unit that has a countermeasure (safety

ultra-low voltage circuit) built-in for preventing high voltages from occurring.

・ Wire the power supply separately from other devices. Wiring them together

or placing them in the same duct may cause induction, resulting in
malfunction or damage.

(2) GND

The GND terminal is the 0V power supply terminal. When using a Sensor
Controller with an NPN output, the GND terminal is also the common I/O
terminal for all I/O except for the Analog output.

(3) OUT0 (ALL PASS output)

This outputs judgment results (ALL PASS).

(4) OUT1 (NG output)

This outputs judgment results (NG).

Push down until you hear it snap into

place.

When Sensor Controllers are used gang-mounted, attach the End
Plate (sold separately PFP-M) on the DIN track beforehand.
Always hook the hook on the connector end on the DIN track rst.
