Each output’s Null and Span is independently adjusted using the sliding bars. When the adjustments are made, the new values can be
temporarily monitored by selecng either the Null Update or Span Update buon. Click OK to save the new sengs and return the
controller to normal operaon. Click Cancel to ignore any Null/Span adjustments and return the controller to normal operaon with the
previously saved null and span sengs.
The MAC controller has a four-minute Null/Span me-out feature that causes the controller to leave the Null/Span adjustment
procedure when neither the Null Update nor the Span Update funcons are accessed. When this me-out condion occurs, the MAC
controller automacally cancels the Null/Span adjustment procedure and returns to the previously saved sengs.
5.4.3 Conguring the Blanking Specicaons
Blanking specicaons allow either one or two areas of the array to be blanked (made blind to acvity within that area).
MAC-1, MACP-1, MACN-1, MACV-1, and MACI-1 Controller Models
Beams are numbered from the
boom (cable end) of the sensors to the top of the sensors. The Low beam number and the High beam
number can be designated to dene a Field to be blanked. Zeros are used as default sengs to signify no blanking.
MAC16P-1 and MAC16N-1 Controller Models
The controller can specify blanking of any light channel and save these specicaons in stac memory. Blanking opons are changed
using the supplied soware.
Under the MINI-ARRAY tasks, select the Alignment funcon to access the Alignment screen. Click Start to scan and update the
Alignment screen.
Available blanking commands include: Clear Blanking Fields, Restore Controller Sengs, Auto Blanking, Abort Auto Blanking, Save to
File, Read From File, Cancel, OK, and Edit.
• Clear Blanking Fields removes all blanking specicaons.
• Restore Controller Sengs reads the previously saved blanking specicaons from the MINI-ARRAY controller.
• Auto Blanking selects all blocked channels for blanking. When the Auto Blanking feature is selected, the sengs may be
accepted or aborted.
• Abort Auto Blanking cancels Auto Blanking.
• File Save and File Retrieve allow the user to save and retrieve blanking data to a
le.
• The OK buon saves the new blanking conguraon to the controller. Aer the OK buon is selected, Restore Controller
Sengs will reect the new blanking conguraon.
• The Cancel buon prevents the new blanking conguraon from being saved.
• The Edit funcon allows individual beams to be blanked by launching the Channel Blanking Edit screen.
The Channel Blanking Edit screen groups the beams into rows with a check box for each beam. For instance, the rst row is labeled
1-16. The rst check box represents the blanking state of channel 1. A check mark indicates that the channel has been selected for
blanking.
The Blank Selected/Clear Selected feature allows the user to select/clear rows of channels.
The OK
buon adds the new blanking addions to the Alignment screen.
The Cancel buon voids the Edit changes.
