6. Installation and Initial Start-Up
6.1 General Installation Instructions
• Observe electrical and mechanical regulations, standards, and safety rules.
• Make sure that the sensor is mounted firmly and securely.
• The power supply should be connected directly and it should be as short as possible.
• The sensor must be protected against mechanical influences.
• The sensor should not be subjected any vibration because this could influence measurement.
• The sensor must be installed such that the laser line is as perpendicular as possible to the surface to be
measured in order to obtain accurate measurement results.
• Adequate heat dissipation must be assured for the device. This can be accomplished, for example, by
means of a metallic connection between the sensor housing and the mounting base.
• A cooling unit should be used as of an ambient temperature of 45° C or in the event that the sensor
is mounted in a thermally insulated manner. Cooling units can be found at www.wenglor.com under
“Supplementary Accessories” on the respective product page.
6.1.1 The Sensor’s Coordinate System
The X-axis corresponds to measuring ranges X.
The a-axis corresponds to rotation around
the X-axis.
The Z-axis corresponds to measuring range Z.
The c-axis corresponds to rotation around the
Z-axis.
The Y-axis corresponds to advancing in the
Y direction.
The b-axis corresponds to rotation around
the Y-axis.
6.1.2 Shadows
A shadow is cast onto the sensor’s range of vision
by the object to be measured in the example shown
at the right.
Measurement is possible without any shadowing in
the example shown at the left.
