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.

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.
