PART DESCRIPTION

MOUNTING

• When mounting this product, use M3 screws (prepare separately). Use a tightening torque of 0.5N･m for mounting.
• When mounting this product using the sensor mounting bracket (optional), also use a tightening torque of 0.5N･m.

Mounting Direction

 

•  Direction to a movable body <When there are differences in material and color>
• When performing measurements of moving objects with excessively different materials and colors, mount the product per the
  following directions to minimize measurement errors.
  <Measurement of rotating objects>
• When measuring rotating objects, mount the product as follows. Measurement can be performed with minimized effect on the object caused by up / down deflection, position deviation and etc. <When there is a step>
• When there is a step in the moving object, mount the product as follows. Measurement can be performed with minimized effect from the edges of the steps.
• Measuring of narrow locations and recesses
• When measuring in narrow locations or inside holes, mount the product so that optical path from the light emitting part to lightreceiving part is not interrupted.
• Mounting the sensor to a wall
• Mount the product as follows, so that the multiple light reflections on the wall do not emit to the lightreceiving part. When the reflection factor on a wall is high, it is effective to use a dull black color.

TEACHING

This is the basic teaching method.

1. Press the TEACH key in the background present condition.
2. Press the TEACH key in the sensing object present condition.
   • Stable sensing is possible
   • Stable sensing is not possible

Limit-teaching

This is teaching method in case small object or object in background are existing.

<When an object in background is used as reference>

<When a sensing object is used as reference>

1. Press the TEACH key in the background present condition or the sensing object present condition.
2. When an object in the background is used as a reference, press the UP key to set the threshold on the sensor side. When a sensing object is used as a reference, press the DOWN key to set the threshold on the sensing object side.
   

1-point teaching (Window comparator mode)

• This is mode is used for setting the threshold range for the distance from the reference value of the sensing object, by performing 1-point teaching. This mode is used for sensing within the threshold range.
• When performing 1-point teaching (window comparator mode), preset “Window comparator mode 1” in the sensing output setting of the PRO mode. For the setting method, refer to “ 12 PRO MODE SETTING.”

1. Press the TEACH key twice in the sensing object present condition. (1st time: TEACH mode, 2nd time: Teaching)
2. Teaching is completed.

2-point teaching (Window comparator mode)

• This is method to set the threshold range by conducting the 2-point teaching.
• When performing 2-point teaching (window comparator mode), preset “Window comparator mode 2” in the sensing output setting of the PRO mode. For the setting, refer to “ 12 PRO MODE SETTING.”
• When conducting teaching, use sensing objects (P-1 and P-2) whose distance are different from each other.

1. Press the TEACH key in the sensing object P-1 present condition. (1st time)
2. Press the TEACH key in the sensing object P-2 present condition. (2nd time)
   1. Stable sensing is possible
   2. Stable sensing is not possible

3-point teaching (Window comparator mode)

•  This is the method to perform 3-point teaching (P-1, P-2, P-3) and to set the threshold range by setting threshold 1_SL in the mid-point between the 1st time and 2nd time, and threshold 2_SL in the mid-point between the 2nd time and 3rd time as shown in the following figure.
• When performing 3-point teaching (window comparator mode), preset “Window comparator mode 3” in the sensing output setting of the PRO mode. For the setting, refer to “ 12 PRO MODE SETTING.”
• When performing teaching, use sensing objects (P-1, P-2, P-3) with different distance.
• After teaching, P-1, P-2 and P-3 will be automatically rearranged from the smaller value.

1. Press the TEACH key in the sensing object P-1 present condition. (1st time)
2.  Press the TEACH key in the sensing object P-3 present condition. (3rd time)
3.  Press the TEACH key in the sensing object P-2 present condition. (2nd time)
   Stable sensing is possible
   Stable sensing is not possible

Span adjustment in rising differential mode or trailing differential mode

• This mode is used to cancel the gradual changes in the measured value, and to only detect sudden changes.
• When performing rising differential mode or trailing differential mode, preset “Rising differential mode” or “Trailing differential mode” in the sensing output setting of the PRO mode. For the setting method, refer to “ 12 PRO MODE SETTING.”
• The threshold can be set by using the threshold value fine adjustment function. For the threshold value fine adjustment function, refer to “ 8 THRESHOLD VALUE FINE ADJUSTMENT FUNCTION.”

1. Press the TEACH key.
2. Press the TEACH key to set.

THRESHOLD VALUE FINE ADJUSTMENT FUNCTION

• Fine adjustment of the threshold can be performed in the measurement display.
• Fine adjustment of the threshold can be performed even after teaching.
  <Normal sensing mode, rising differential mode or trailing differential mode>

<Window comparator mode>

• When the sensing output is set to window comparator mode, the display of “ ” and “ ” can be changed by pressing the TEACH key for 1 second.
  When performing a fine adjustment of the threshold of “ ” or ”, press the UP key or DOWN key. After “ ” or “ ” is displayed, the fine adjustment of the threshold can be performed.

PEAK / BOTTOM HOLD FUNCTION

• The peak / bottom hold function, is for displaying the peak value and bottom value.
• When the zero set function is executed while the peak / bottom hold function is set to “Peak hold” or “Bottom hold”, the held measured value will be reset.

ZERO SET FUNCTION

• The zero set function is the function to compulsorily set the measured value to “zero”.
• T he zero set indicator (yellow) will turn ON when the zero set is valid.
•  When the zero set function is executed while the peak / bottom hold function is valid, the held measured value will be reset.
• W hen the display setting is set to Offset, the zero set function cannot be set. <Zero set setting>

W hen the power is turned ON again, zero set from external input can be released. At this time, the zero set will not be saved.
Even when the zero set is set in the sensor, the zero set can be set or released from an external input. However, when the power is turned ON again, the zero set set in the sensor will be displayed.

KEY LOCK FUNCTION

• The key lock function is to prevent acceptance of key operations, so that the conditions set in each setting mode are not changed accidentally.
• When key operation is performed after the key lock is set, “ ” will be displayed on the digital display.

PRO MODE SETTING

• The PRO indicator (yellow) will turn ON when the PRO mode is set.
• When the DOWN key is pressed for 3 seconds or more in the middle of the PRO MODE setting, the display returns to the measurement display.

• Do not use this product during the transient state when the power supply is turned ON.
• The overall length of the cable can be extended to 10m maximum with a cable size of 0.3mm2 or more.

ERROR INDICATION

SPECIFICATIONS

Notes:

1. Supply voltage: 24V DC, ambient temperature: +20°C, response time: 10ms, and analog output value of measurement center distance are used for unspecified measurement conditions. The subject is white ceramics.
2. This is based on the FDA Standard, according to Laser Notice No. 50 of the FDA Standard.
3.  This is the size in the measurement center distance. These values were defined by using 1/e2 (approx. 13.5%) of the center light intensity. Due to leak light outside the specified area, the reflectance around the detecting point may be higher than at the point and this may affect the measurement value.

CAUTIONS

• This product has been developed / produced for industrial use only.
• Make sure that the power supply is OFF before starting the wiring.
•  If the wiring is performed incorrectly, it will cause a failure.
• Do not run the wires together with high-voltage lines or power lines, or put them in the same raceway. This can cause malfunction due to induction.
•  Verify that the supply voltage variation is within the rating.
•  If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
• If noise generating devices (switching regulators, inverter motors, etc.) are used around the sensor mounting area, make sure to connect the frame ground (FG) terminal of the device.
