2.3.1 Installation Precautions
WARNING!
• Installing this product in a location with any of the
following conditions may lead to re, electric shock,
or malfunction:
• High humidity
• High temperatures caused by direct sunlight, etc.

CAUTION
• Avoid wiring in parallel with or in the same piping
as high-voltage wires or power lines.
Doing so may lead to malfunctions caused by noise.
Also, shorten the power supply and signal wires as
much as possible.
• Be careful to avoid damaging the cables by pulling
on or applying unnecessary force on them.
This section explains the contents and axing position of the warning label
used on this product.
A laser beam is used in the location where this warning label is axed.
Looking directly at the laser beam may lead to loss of eyesight. Be sure
to follow the precautions shown below.
1. Do not look at the laser beam.
2. Do not remove the protective cover.
3. All individuals other than the proper operator must not
approach the product.

The Proler 2 is a high-precision prole measurement sensor.
The characteristics of this product are shown below.
• This product achieves high-precision measurement by emitting a bandshaped laser beam and using a light-plane-intersecting method that
triangulates the reected light.
• Settings can be congured, measurements can be performed,
and output can be generated from the sensor. No amplier unit
or other auxiliary devices are necessary.
• Various settings can be set from the sensor or from the dedicated setup
software (PRO2-navigator).
• It is possible to measure 4 areas with a single measurement. For each
area, there are 13 types of measurement functions to select from.
• There are 4 camera modes available. This enables you to select
the optimum settings to match the environment of the production line
to be measured and the state of the target object.
With the light-plane-intersecting method, the reected light from the
emitted band-shaped laser beam is received by the light receiving element
(CMOS), and the prole is then measured from the resulting image data.
With the light-plane-intersecting method, two processes are used to
determine the height and position.
• Triangulation: To determine the height, this process obtains the received
light waveform (the waveform of the reected light) for each vertical line
of the image.
• Projection transformation: To determine the horizontal position,
this process mathematically calculates the actual position from
the image data.

The Proler 2 performs measurements by emitting a parallel laser
beam and receiving the reected
light.
During measurement, ensure that
the laser beam and reected light
is not blocked by the target object.
Before using the product, check
that stray light, which is reected
by a wall or by highly reective
objects, does not have an eect
on the measurements.
1. Insert the included mounting screws (two M4 × 50 mm screws)
into the mounting holes to temporarily ax the sensor to a location
that is roughly in the desired location.
2. Measure the distance between the sensor and the detection
target object. Please make sure the measuring object is within the
measuring area.
3. Adjust the sensor position on the basis of the measurement result,
and then use the included nuts and washers to x the screws in place.
You can take basic measurements simply by setting the following three
items. Congure the settings from the sensor or from the PRO2-Navigator
setup software.
• Shutter time
• Area
• Output conditions
Reference: For the actual screens and for information on the operations,
see the following pages.
Conguring settings from the sensor
Using PRO2-Navigator
1. Set the shutter timePosition the measurement target, and then perform automatic adjustment.
The optimum shutter time will be set.
→ “6.3 PRO2-Navigator Screen and Operating.”
→ “5.3 Setting.”
2. Set the areaUse the area setting to specify what part you will measure and how that
part will be measured.
1. Measurement area
• Set what part within the measurement range will be measured.
The set area must intersect the prole (the sectional waveform).
2. Measurement function
• Set the measurement function. You can select from functions
such as height and width.
Reference: For details on the area settings, see “7.6 Area Settings.”
3. Set the output conditionsCongure the settings related to the output of the measured results.
First, specify the judgment and output target area.
• Output target
Select the target area (area 1 to area 4 and calculation 1 and
calculation 2).
1. Measurement output
The product judges whether the measurement is a pass or a fail,
and then outputs the result.
• Upper limit/lower limit
2. Analog current output (4 to 20 mA)
• 4 mA/20 mA
Set the lower and upper limits of the analog output range.
When you have nished conguring settings or when you are not sure what
menu you are currently on, you can follow the procedures below to return
to the main menu (the measurement screen).
