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 selecting either the Null Update or Span Update button. Click OK to save the new settings and return the
controller to normal operation. Click Cancel to ignore any Null/Span adjustments and return the controller to normal operation with the
previously saved null and span settings.
The MAC controller has a four-minute Null/Span time-out feature that causes the controller to leave the Null/Span adjustment
procedure when neither the Null Update nor the Span Update functions are accessed. When this time-out condition occurs, the MAC
controller automatically cancels the Null/Span adjustment procedure and returns to the previously saved settings.
5.4.3 Configuring the Blanking Specifications
Blanking specifications allow either one or two areas of the array to be blanked (made blind to activity within that area).
MAC-1, MACP-1, MACN-1, MACV-1, and MACI-1 Controller Models
Beams are numbered from the bottom (cable end) of the sensors to the top of the sensors. The Low beam number and the High beam
number can be designated to define a Field to be blanked. Zeros are used as default settings to signify no blanking.
MAC16P-1 and MAC16N-1 Controller Models
The controller can specify blanking of any light channel and save these specifications in static memory. Blanking options are changed
using the supplied software.
Under the MINI-ARRAY tasks, select the Alignment function to access the Alignment screen. Click Start to scan and update the
Alignment screen.
Available blanking commands include: Clear Blanking Fields, Restore Controller Settings, Auto Blanking, Abort Auto Blanking, Save to
File, Read From File, Cancel, OK, and Edit.
•
Clear Blanking Fields removes all blanking specifications.
•
Restore Controller Settings reads the previously saved blanking specifications from the MINI-ARRAY controller.
•
Auto Blanking selects all blocked channels for blanking. When the Auto Blanking feature is selected, the settings 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 file.
•
The OK button saves the new blanking configuration to the controller. After the OK button is selected, Restore Controller
Settings will reflect the new blanking configuration.
•
The Cancel button prevents the new blanking configuration from being saved.
•
The Edit function 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 first row is labeled
1-16. The first 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 button adds the new blanking additions to the Alignment screen.
The Cancel button voids the Edit changes.
