Measuring an Object

Procedures when measuring an object

This section describes the operating procedures when measuring an object using by the control module.
1.
Turning on the external power supply
Turn on the external power supply.
Page 32 Connection method of external power supply
2.
Power-on the programmable controller.
Power on the programmable controller and start up the control module.
If the external power supply is not supplied more than five seconds after the programmable controller is powered on, the
external power supply interruption error (error code: 3010H) occurs.
3.
Check that the laser displacement sensor is start-up.
Check that the sensor head emits a laser beam and the laser radiation indicator is on.
Be careful of the following when checking the laser displacement sensor is start-up.
• When the sensor head is start-up (the laser radiation indicator (LASER ON) is on), laser emission starts regardless of
whether the state of CPU module is RUN or STOP.
• Be careful that not to point the laser beam to people's eyes when the sensor head is start-up.
• Allow at least 40 to 50 seconds after power-on to use a laser beam.
• Allow at least 30 minutes of warming up after emitted laser beam from a sensor head to ensure the performance of the
sensor head.
• If the RUN LED of the control module is not turn on, check that the programmable controller is turned on and the external
power supply is connected to the control module.
4.
Starting up the setting tool.
Start the setting tool.
5.
Set the default recipe.
Set the basic settings depending on a measurement object in the default recipe.
To select the measurement object in the default recipe can be set the following settings.
• Head setting
• OUT setting
• Common setting

6.
Position adjustment of sensor head
Checking the connecting direction of a sensor head. Select the optimum direction according to the shape or moving direction
of the measurement object.
• Checking the installation
The installation for the specular reflection measurement is different from that for the diffuse reflection measurement.
• Checking the measurement center
The measurement range indicator (RANGE) turns on in yellow around the measurement center.
• Checking the measurement range
Move a measurement object to check the displacement of the object is within the measurement range.
The measurement range indicator (RANGE) blinks in yellow when the object is within the measurement range.
Check that the received light intensity waveform of the sensor head A and B on the received light intensity waveform window
of the setting tool.
