Safety Measures for the Laser

■ Laser emission stop input

The laser emission can be stopped by selecting the “Laser emission stop” signal (20 ms or more) from the input functions and inputting it externally. The emission stops while the signal is being input. The laser beam is emitted in 20 ms after the signal input is canceled. The control output functions according to the received light intensity even while laser emission stop is input.

Note

When the power is turned on, even when the laser emission stop signal is input, the laser is emitted for about 60 ms for self-diagnostic purpose.

■ % calibration (not available for the LV-S31)

This is a calibration method that can set the setting value by percentage with reference to the received light intensity at the time of sensitivity setting. For example, if the target value is set to –10P, the setting value is determined 10% lower than the received light intensity when the SET button is pressed. By regularly performing external calibration from the device such as a PLC, even a little sensitivity difference can be steadily detected.

Note

The % calibration function cannot be used when the DSC function is turned on or the zero datum calibration is being used.

1 When selecting the sensitivity

setting method (page 7, No. 5), select the % calibration, and set the target value of calibration.

(The value can be set by 1%.)

2 Taking the desired light intensity as

a reference (normally without a workpiece), press the SET button.

* While the % calibration is in use, other calibrations (sensitivity setting) can-

not be used.

* The setting value is calculated based on the intermediate value between

MAX. and MIN. of the received light intensity while the SET button is being pressed. The conditions in acquiring the sampling value can be changed using the procedure to set the special modes.

■ Edge detection (not available for the LV-S31)

Detects the change in the received light intensity during a given period of time. In the detection mode (page 7, No. 4), select the following edge detection mode and the detection time.

DSC (Dynamic Stability Control)

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. At Detection mode selection (page 7, No.4), select " ".* How to set the sensitivity is the same as in the normal mode. * The value is stored in memory even after the power is turned off.

Note

•

When connected to a sensor head other than LV-S31/S41/S41L, the DSC function turns on automatically when the zero datum calibration is performed and operates while turned on when there is blocked light. When other calibrations are performed in this state, the DSC function is turned off.

Shift Function

Forcibly synchronizes the received light intensity with the preset value (shift target value). (Adds and subtracts the received light intensity.) Regular synchronization inputs from a PLC or other device stabilizes the detection of the target that has a little light intensity difference.

Note

The shift function cannot be used when the DSC function is turned on or the zero datum calibration is being used.

Cautions on Installing the Reflector (LV-S61/S62/S63)

Be sure to install the reflector so that it is vertical or horizontal against the sensor unit.

If the reflector is installed diagonally against the sensor unit, the received light intensity will decrease significantly.

Error Indication

The following indications on the LCD display show the error events. Correct the problem using the following countermeasures.

Error indication Cause Remedy

ErH

ErC

ErE

Sensor head is not connected. Head cable is broken.

Overcurrent flows through the output wire.

Data write/read error • Per form initialization.

Data has been written in the EEPROM more than one million times and can no longer be updated.

The following table shows the alarms when "Auto" is selected for the operation of control output "2"and channel setting is switched to "2". Refer to the following table to remedy the alarms.

Display Alarm contents Remedy

Over DSC correction limit: Received light intensity during OFF exceeds the DSC correction limit.

DSC small fluctuation detection: There are fluctuations within the range for the alarm output level (rtio).

Invalid DSC EEPROM contents: Failed to write data to EEPROM.

Over fluctuation width during zero datum calibration: The fluctuations of received light intensity during calibration are too large.

DSC speed limit alarm: The received light intensity fluctuated a large amount in a short period of time.

• Check that the sensor head is connected.

• Check that the head cable is not broken.

• Check the connection of the head cable to the connector.

• After checking these points, turn on the power again.

• Check the load and reduce the current to be within the rated range.

• Check that the output wire does not touch another wire or a frame.

• If you need to write more data, replace the amplifier unit.

Change the setup conditions or replace the sensor, and secure the correct received light intensity during OFF.

Move the workpiece to the correct position.

Restart the power or initialize.

Take anti-vibration measures in order to suppress fluctuations during calibration.

• Move the workpiece to the correct position.

• Take anti-vibration measures in order to suppress fluctuations in the received light intensity.

Tips on Correct Use

• To extend the amplifier unit cable, use the cable with the nominal crosssectional area no less than 0.3 mm m. (Contact your nearest KEYENCE office when in the event of additional installation.)

• Separate the wiring of the sensor cable from the power line or the high voltage line, since the use of these lines in the same pipe generates noise, which may cause malfunction or product breakdown.

• If you use a commercially available switching regulator, be sure to ground the frame GND terminal and the GND terminal.

• Do not use the LV-S Series at a location where external light directly falls on the light-receiving surface.

• When setting the sensitivity, the detection distance may vary depending on the individual characteristics.

• If you wire the unit incorrectly, the LV-S Series may become hot, or the sensitivity may change.

• Do not connect the sensor head connector to the amplifier unit more than 100 times.

• Displayed values may slightly change depending on the environment (temperature shift, dust, etc.).
