SCANNING AREA

The IEC/DIN Warning labels are packed with the scanning head. Stick the Warning labels on the scanning head or the vicinity where the scanning head is mounted in order to be easily seen by the operators.

1.4 Safety Consideration

Use of controls or adjustments or the performance of procedures other than those specified herein may result in hazardous radiation exposure.

The LS-5041 employ a visible semiconductor laser for its light source. The beam is not harmful to the skin. The possible health hazard is in exposing the eyes to the laser beam. Damage to the eyes occur if the operator stares directly into the beam.

Chapter 1 Laser Safety Precautions

WARNING

Follow the safety precautions below to ensure operator safety:

• Operate the LS-5000 series only according to the procedures described in this instruction manual.

Otherwise, injury may occur due to exposure to the laser beam.

• Do not disassemble the scanning head.

Laser emission from the LS-5000 series is not automatically stopped if the scanning head is disassembled. If you disassemble the scanning head for inspection or repair, you may be exposed to the laser beam. If the LS-5000 series malfunctions, contact KEYENCE immediately.

• Do not look directly into the laser beam.

Looking directly into the laser beam may result in serious eye injury.

• Protective enclosure

We recommend that you install a protective enclosure around the scanning head to prevent any person from getting near the scanning head during operation.

• Protective goggles

We recommend that you wear protective goggles when using the LS-5000 series.

• You must stop all laser emissions before cleaning the laser aperture. Otherwise, you may be exposed to the laser beam.

• Be aware of the optical axis of the laser beam. If you may be exposed to a specularly-reflected or diffused laser beam, provide an enclosure with reflectivity and thermal characteristics adequate to interrupt the laser beam. Install the LS-5041 so that the optical axis of the laser beam will not be at the same height as your eyes when operating the LS-5000 series.

1.5 Safety Features Provided with the LS-5000 Series

The LS-5000 series comes with the following safety features:

CAUTION

1.6 Preparation for Operation

■ Suppressing noise interference

Be sure to isolate the connection cable from high-voltage or power lines. If the connection cable is placed in the same conduit as these lines, the LS-5000 series may malfunction due to noise interference.

■ Cooling fan

Do not block the cooling fan at the bottom of the LS-5501. If the cooling fan is blocked, the LS-5501 may overheat and malfunction.

■ Operating environments

• Use the controller at an ambient temperature of 0°C to 45°C (32 to 113°F), No freezing.

• Fluctuations in the ambient temperature cause measurement errors; therefore, the ambient temperature should be kept constant. If the temperature changes by 10°C (18°F), the LS-5000 series will take approximately 60 minutes until the temperature distribution in the unit becomes even.

• Do not allow any substance which may refract the laser beam, such as water and oil, to adhere to the scanning head.

* Blow dust off the protective glass using clean air. Wipe off any remaining dust

using a soft cloth moistened with alcohol.

Note 1: Measurement conditions When the target oscillates, the measured value may fluctuate. The measurement accuracy can be improved when the number of averaging measurements is set higher.

Note 2: Target When the target shape or luster varies, a measurement error may occur. In this case, place a standard target in the measuring area and perform the calibration using the [CALIB] key.

This width can be measured when SEG(m,n) is set to (0,2) in Normal mode.

5.1 Area/Segment/Edge

When a target is placed in the measuring area, there are areas where the laser beam is received (laser beam enters the receiver), and where the laser beam is interrupted by the target (shadow of the target is projected on the receiver). The border between the light and dark areas is called “EDGE”. Each section divided by the edge is called a “SEGMENT”. The measurement "AREA" is determined by two edges and includes all "SEGMENTS" between these two edges.

* The edge number is counted in the laser scanning direction starting at T.EDGE

(top edge).

5.2 Normal Mode

Note: EDGE 0

The position of the photodiode for synchronization is called “EDGE 0”. EDGE 0 can be used as a reference point during roller oscillation measurement or sheet edge control. (No reference edge is required.)

Example: Roller oscillation measurement

➮

For the setting procedure, see p. 39.

The LS-5000 series has two measuring modes; NORMAL and PITCH. NORMAL mode provides four types of measurement3: “DIA”, “T.EDGE (Top Edge)”, “B.EDGE (Bottom Edge)” and “SEG(m,n)”. The function of each mode is described below. Select the mode that suits your measurement condition.

DIA mode

Measurement of outer diameter of rod or electric wire

T.EDGE/B.EDGE modes

Measurement of gap between rollers or position of target edge

SEG(m,n) mode

Chapter 5 Outline of Measurements

Example: Outer diameter measurement using a rod or transparent object

The width between the lower edge of the first light segment and the top edge of the last light segment is measured.

• When one target is measured

• When several targets are measured

5.2.2 T.EDGE (TOP EDGE) Mode / B.EDGE (BOTTOM EDGE) Mode

Example: Measurement of a gap between rollers

T.EDGE: Measures the width of the first light segment. B.EDGE: Measures the width of the last light segment.

5.2.3 SEG (m,n) Mode

Example: Inner diameter measurement using a bearing

When two edges are specified, the width between these edges is measured.

* (m,n) indicates any number between 0 and 254. “m” should be smaller than “n”.

Note: DIA mode

Since DIA mode is basically intended for outer diameter measurement of a rod, transparent tube or other round surface, the measurement error due to the round surface is calibrated. To perform outer diameter measurement of a round target, select DIA mode.

Setting Scanning Head and Measurement

1. Setting Measuring Area

The LS-5000 series can simultaneously perform four measurements and outputs with one scanning head, and different measurements and outputs with four scanning heads. The place for which the measurement condition is set is called the “measuring area” (A1 to A4), where the scanning head number and measuring mode can be set.

(➮ See note.)

Note: The LS-5002 and 5502 can only control a single scanning head.

2. Setting Output Mode

The LS-5000 series can accept measurement data from multiple scanning heads and perform calculations on the data for displaying and outputting the comparator result. Using the preset measuring area (A1 to A4), you can set various calculation and measuring modes, as well as the number of averaging measurements as shown below.

C Analog Output Function

Chapter 6 Normal Mode

An analog voltage proportional to the displayed value can be output using an optional I/O board in the range of ±10 V. The analog output scaling range is between -99.9999 and 999.9999 in “mm” (-

0.99999 and -99.9999 in “inch”), and the ripple is 5 mV.

● Scaling

The analog output is scaled to set the changing rate (inclination) of the analog output relative to the displayed value. Enter a value to be displayed, relative to +10 V and -10 V respectively.

When the analog output is set to “+10 V = 30.000” and “-10 V = 10.000”, the relation between analog output and displayed value is as follows:

Note: Resolution

The resolution of the LS-5000 series’ analog output is 5 mV. The resolution in displayed value varies depending on the scaling.

Example 1

When the analog output is set to “+10 V = 10.000” and “-10 V = -10.000”: 20 (V) : 0.005 (V) = 20 (mm) : x (mm) x = 0.005 mm

Example 2

When the analog output is set to “+10 V = 40.000” and “-10 V = 0.0000”: 20 (V) : 0.005 (V) = 40 (mm) : x (mm) x = 0.010 mm

Up to three pitches can be excluded from measurement, based on the application, as shown below.

If pitch (1) and pitch (13) are included in the measurement of connector lead pitches as shown on the right, the maximum value becomes larger than the actual value. The masking function is useful to cancel these unnecessary part in such a case.

■ Setting Procedure

1. Select the OPTIONS screen. Press the [OPTIONS] button.

2. Set the masking function. Press the button corresponding to the output for which the masking function is to be set.

3. Press the [MASKING] button.

In this example, set the No. of Pitches to 13.

Enter the pitch number to be canceled using the numeric keys, and press [ENTER]. Press [ESCAPE] to complete the entry. Press [CANCEL] to cancel the entry. The value returns to the previous value.

In this example, set MASK1 to 1 and MASK2 to 13.

Note 1: Pitch number is counted from Pitch 1 in the scanning direction (from the top of the scanning

head to the bottom).

Note 2: When the total number of pitches changes (i.e. due to lead breakage), the control I/O board’s HI3 output is turned ON which indicates an "Error with No. of Pitches”. (Except for the self-timing mode)

Example: Send the measured value from OUT No. 2 continuously.

Note 1: When the LS-5000 series receives the “N” (continuous output) command in either peak hold, bottom hold, difference hold, sample hold or self-timing mode, the LS-5000 series sends the measured value once every time the synchronous input is turned on (the measured value is confirmed).

Note 2: When the LS-5000 series receives the “N” (continuous output) command in either normal, auto peak, auto bottom or auto difference hold mode, the LS-5000 series continuously sends the measured value.
