Gocator Line Profile Sensors: User Manual

Type Description
Stationary
Stationary is used when the alignment target does not move. This type of
alignment can only compensate for mounting inaccuracies in the laser plane (Z
offsets, and optionally X offsets and Y angle rotation). It is typically used when the
sensor will run in Profile mode.
Moving
Moving is used when the alignment target moves beneath the sensor. This type
allows for Y offset and Zangle alignment, in addition to X and Z offset and Y angle
alignment. It is typically used when a sensor will run in Surface mode.
Aligning Sensors
Alignment is configured and performed using the Alignment panel.
With certain types of alignment, a Degrees of Freedom setting lets you choose the axes on which
offsets and rotations are calculated. If the setting is not available, only X and Z offsets, and Y angle
rotation, are calculated. That is, alignment is only performed within the profile plane. When the Degrees
of Freedom setting is available, it provides options that let you perform alignment outside the profile
plane. For more information, see the procedure on performing moving alignment.
To prepare for alignment:
1. Choose an alignment reference in the Manage page if you have not already done so.
For more information, see Alignment Reference on page 105.
2. Go to the Scan page.
3. Choose a mode other than Video mode in the Scan Mode panel.
4. Expand the Alignment panel by clicking on the panel header or the button.
5. Ensure that all sensors have a clear view of the target surface.
Remove any irregular objects from the sensor's field of view that might interfere with alignment. If
using a bar for a dual- or multi-sensor top-down or bottom-up system, ensure that the lasers illuminate
a reference hole on the bar.
To perform stationary alignment:
1. In the Alignment panel, select Stationary as the Type.
2. Clear the previous alignment if present.
