Setting Sensitivity with Signals from External Devices (Page 6, No. 6)

By selecting "External calibration" in page 6, No. 6, the signal from an external device can be used to set the sensitivity. See "Using External Input" (page 4).

●

Percent (%) Calibration (Page 6, No. 3)

The sensitivity can be set as a percent (%) of received light intensity. For example, when the percentage calibration target value is set to "-10P", pressing

SET

the button sets the value to 10% below the amount of received light.

When selecting the sensitivity setting method (page 6, No. 3), select percent

calibration, set the target value of calibration, and return to the normal display.

Press the button at the percentage for the desired reference for light intensity.

Dynamic Sensitivity Correction (DSC) Mode (Page 6, No. 5)

DSC automatically corrects the setting value according to the changes in the received light intensity when there is no workpiece (output OFF). This function is effective when the light intensity difference is small when judging whether or not there is a workpiece.

Select "Dynamic Sensitivity Correction" in page 6, No. 5.

■

Sensitivity setting

Connecting the Cables and the IDC Connector

Note

When the cable length of the sensor head is changed, be sure to connect the ampliﬁer to check that it operates correctly.

1 Manipulate the end of the cables as shown in the following ﬁgure.

•

Peel back the insulation 10 mm from the end. (Do not strip the wires in the core.)

•

Twist the base of the shielded wire at least ﬁve times so it does not unravel, and bend it 90° to the side.

Core wires

90°

Note

Do not install the connectors more than two times. If the installation exceeds twice, purchase OP-77758 (two connectors) separately. If "ErH" appears on the ampliﬁer even when using pliers to crimp the connector, press the cable (part A) between the metallic contacts with a thin tool such as a flathead screwdriver to crimp the cable more firmly.

* Be careful not to twist the core wires along with the shielded wire.

If the wires become twisted, untwist them slightly and pull the core wires apart from the shielded wires.

2 Align the core wires with the same color as indicated by the sticker on the IDC

connector and insert the wires as shown below.

• Insert the two wires (one black and one white) for the black cable (receiver

side) into the connector completely.

• The red wire for the gray cable (transmitter side) cannot be inserted

completely, but insert it as far as it can go.

• Twist the shielded wires in the direction of the arrow while pulling them into

the ditches.

Hints On Correct Use

•

Do not wire the amplifier line along with power lines or high-tension lines,

•

otherwise the sensor may malfunction or receive damage due to noise.

•

When using a commercially available switching regulator, ground the frame ground terminal and ground terminal.

•

Do not use the PX series outdoors, or in a place where extraneous light can enter the light receiving surface directly.

•

Due to the individual dispersion of characteristics and the difference in sensor head model, the maximum sensing distance or displayed value of all the units are not the same.

•

)

Changing the cable layout can change the light intensity slightly. Reset the sensitivity when changing the layout.

•

Even when using the interference prevention function, devices installed and connected to the sensor may have a slight effect on detection. In these cases, fine-adjust the sensitivity (raise the value).

•

Infrared light used for communicating with the amplifier unit emits from the back of the amplifier unit. Make sure that the receiving head is not used too close to the amplifier unit.

•

Do not use the sensor while it is submerged in oil.

•

Performance may be lowered depending on the type of oil.

Precautions on UL Certificate

The PX series complies with the following UL and CSA standards. The PX series has obtained UL and C-UL certificate.

•
