When training clients to use Fixturlasers Verti-Zontal Alignment Process we show taking the 3rd measurement at a horizontal position, typically at 3 o’clock. This is simply for expediency and is NOT a requirement as Fixturlaser Shaft Alignment Systems can take measurements at any position due to the inclinometers in M & S sensors.

If possible we want to have the sensors in a horizontal plane when the live screen is activated so the sensors are in position to monitor the horizontal correction. For rotating machines with large mass or that are difficult to position precisely, this may be time consuming and/or not possible. Other shaft alignment applications may have obstructions at both the 3 & 9 o’clock positions.

Should this occur the Fixturlaser NXA will advise the alignment tech when the sensor position is not ideal to monitor the horizontal correction with this screen.

For these situations the Extended Alignment Function or Utility should be turned on. Extended Alignment allows the horizontal position to be monitored as long as the sensors are within +/- 45o of the 3/9 o’clock positions. (Also +/- 45oof the 12/6 o’clock positions when making live vertical adjustments on machines mounted on adjustable chocks.) When using Extended Alignment, diagonal red stripes will be displayed on the coupling and foot value fields.

To turn on the Extended Alignment Function, touch the Tools icon then the Extended Alignment icon.

Touch the Extended Alignment icon to turn on the function, then touch the check mark icon(s) to exit back to the alignment.

Complete the alignment as normal with the Verti-Zontal Process.

The Extended Alignment Function will remain on until the user turns it off.
