SAFETY PRECAUTIONS ON LASER PRODUCT 4. Safety consideration CAUTION Use of controls or adjustments or the performance of procedures other than those specified herein may result in hazardous radiation exposure. 1) Class IIIb/3B laser products WARNING Follow the instructions mentioned in this manual. Otherwise, injury to the human body (eyes and skin) may result. • Do not directly look at or touch the laser beam and its reflection from a mirror-like surface.
SAFETY PRECAUTIONS ON LASER PRODUCT 3) Class 2M laser products WARNING Viewing the laser output with certain optical instruments designed for use at a distance (for example, telescopes and binoculars) may pose an eye hazard. Follow the instructions mentioned in this manual. Otherwise, injury to the human body (eyes and skin) may result. • Do not stare into the beam. • Do not direct the beam at other people or into areas where other people unconnected with the laser work might be present.
SAFETY PRECAUTIONS ON LASER PRODUCT For use with shield: PRECAUTIONS ON REGULATIONS AND STANDARDS Attach the shield to the front surface of the sensor head. CE Marking LB-041/LB-081 Applicable Models: LB-041/LB-1001W, LB-081/LB-1101W and LB-301/ LB-1201W Keyence Corporation has confirmed that these products comply with the essential requirements of the applicable EC Directives, based on the following specifications.

CONNECTIONS LB-1001/1101/1201 CAUTION Be sure to confirm the model number. ■ Description of terminals 3 Earth ground terminal * GND terminals 4, 0, and B are connected internally. 5 Alarm output (NPN open-collector) Outputs if light quantity is insufficient or excessive, or when no target is present in the operating range. 6 AUTO ZERO input Connecting this terminal to a GND terminal (4, 0, or B) resets the analog voltage output to 0 V (12 mA for current output).
CONNECTIONS INSTALLATION ■ Description of DIP switches DIP Controller RESPONSE MANUAL MAIN LASER POWER MAX 1 2 3 4 FUZZY SUB AUTO LOCK ZERO FREE The controller can be mounted to a DIN rail. When mounting or removing the controller, pull the claw (bottom center) in the direction of the arrow. The controller can also be screw-mounted using the mounting holes provided. 1 RESPONSE speed mode selector switch To use the FUZZY logic control circuit, set the switch to FUZZY.
SETTING AUTO ZERO/OUTPUT ADJUSTMENT 1. Adjust the distance between the sensor head and target and confirm the position with the LASER ON alarm LED. Set the sensor head so that the laser emitting surface is parallel to the measuring surface of the target, then secure it in place. (See figure below.) Press the AUTO ZERO key to reset the output voltage to zero at the mounting position. Example: LB-041 The LED light green.

SETTING DIP SWITCH 1 (FUZZY LOGIC CONTROL) To use the FUZZY logic control circuit, set DIP switch 1 to FUZZY (bottom setting). (The switch is factory-set to MANUAL) DIP 1 2 3 4 The FUZZY logic control circuit is used to obtain both stability and high response speed when measuring a target traveling on a production line. FUZZY mode settings • RESPONSE speed selector switch MID Select for normal measurement.
SETTING DIP SWITCH 2 (INTERFERENCE SUPPRESSION FUNCTION) When using 2 sensor heads in close proximity, set the DIP switch of one controller to MAIN, and that of the other to SUB to suppress interference. (This can also be used for synchronized measurement.) Alternating oscillation frequency and ON/OFF ratio (all models) Frequency 30Hz ON/OFF ratio 1:1 A B Synchronous ON (timing) pulse OFF Note DIP 1 2 3 4 Wire as follows.
SETTING DIP SWITCH 3 (LASER POWER CONTROL) SETTING DIP SWITCH 4 (AUTO ZERO) Laser power control AUTO ZERO setting lock DIP 1 2 3 4 DIP 1 2 3 4 When the DIP switch is set to AUTO (bottom setting), emitted laser beam quantity is automatically controlled according to the reflectivity of the target. The switch is factory-set to MAX. DIP switch 4 is factory-set to FREE. In this mode, AUTO ZERO can be performed by either using the key on the controller panel or short circuiting the terminals.
TROUBLESHOOTING If a problem occurs, first apply the remedy given in the troubleshooting guide below. If this does not solve the problem, please contact your nearest distributor or Keyence office. Problem Analog voltage does not change. (Measured value is not indicated.) Cause Sensor head is incorrectly mounted. Remedy Secure sensor head in range where LASER ON alarm LED lights yellow or green. Connector of sensor head is Fully insert connector to make not firmly inserted. proper contact.
HINTS ON CORRECT USE Compatibility AUTO ZERO function lock (DIP switch 4 ) CAUTION The controller and sensor head of the LB-1000 series have been factorycalibrated in pairs. Therefore, in order to satisfy specifications, be sure to use a sensor head and controller having the same serial number.
