Safety Information for LV-S series

Safety precautions on laser products

* The classification is implemented based on IEC60825-1 following the

requirements of Laser Notice No.50 of FDA (CDRH).

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.

LV-S41/S41L Connecting the Sensor Head and the Amplifier Unit Be sure to use the supplied mounting bracket. ■ How to connect the amplifier unit and the connector 1 1 Open the dust cover, and tilt the hold-lock lever. Press the mounting bracket on the sensor head. Be sure to hook the A portion of the mounting bracket on the B portion of the sensor head. A 2 3 Raise the hook, and insert the connector to the very end.

% calibration (not available for the LV-S31) Setting Sensitivity 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.

Area Detection Mode Setting the Display Scaling Setting value 1 (Upper limit) Setting value 2 (Lower limit) Received light intensity This mode is suited to detecting the received light intensity only of a certain range. This is the function to adjust the received light intensity during operation to the “scaling target value”. (not available for the LV-S31) Usage 1 OFF ON 2 OFF When setting a display scaling (page 6, No. 6), select to use the display scaling, and set the target value.

How to Set up Each Mode (LV-S41/S41L/S61/S71/S72) The settings of Output 1 and 2 can be divided into common settings and individual settings depending on the modes. Change the mode by using the channel selection switch. To exit the mode setting while it is not completely finished, press the MODE button for over 2 seconds. Refer to page 7 when using the LV-S31. Setting the target value of the % calibration Press the or button to select. From –99% to +99% can be set.
