2 Overview
The Banner A-GAGE®MINI-ARRAY measuring light screen is ideal for applicaons such as on-the-y product sizing and proling, edge-
guiding and center-guiding, loop tensioning control, hole detecon, parts counng, die ejecon vericaon, and similar uses.
A typical MINI-ARRAY System consists of the following components:
• Controller module
•Emier
• Receiver
• Two interconnecng cables
Sensors are available in array lengths from 6 inches to 4 feet (in 6 inch increments), plus 5 foot and 6 foot array models. Sensors are
available with either 9.5 mm (3/8 inch) or 19.1 mm (3/4 inch) beam spacing, which translates to either 32 or 16 beams per foot of array
length. Sensors with 3/8-inch beam spacing have a sensing range of up to 6 m (20 ). Sensors with 3/4-inch beam spacing have a
sensing range of up to 17 m (55 ); 5 and 6 arrays have shorter ranges.
Some typical MINI-ARRAY applicaons are:

2.1 System Features
Built-in features simplify the operaon of the A-GAGE MINI-ARRAY system. Programmable beam blanking accommodates machine
components or other xtures that must remain in or move through the light screen. Blanking is set by using the included conguraon
soware. See ######## for more informaon.
Built-in diagnosc programming and easy-to-see indicators on the sensors and the control module make alignment and troubleshoong
easy. The emier has a red LED that signals proper operaon. The receiver has three bright LEDs: green signals that the sensors are
properly aligned; yellow signals marginal alignment; and red signals misalignment or a blocked condion.
The control module has seven status indicators: ve red LEDs signal when outputs are conducng, Alarm output conducng, and gate
signal received; a green LED signals that the sensors are properly aligned. DIAG 1, 2, and 3 LEDs indicate system status. A key to the
diagnoscs codes is printed on the side of the control module for simplied troubleshoong.
The MINI-ARRAY System provides a wide selecon of sensing and output opons, including: measurement (“scan analysis”) modes and
scanning methods that can determine the target object’s locaon, overall size, total height or total width. Scanning may be connuous
or controlled by a host process controller or a gate sensor. Some models (MAC1, MACP, MACN) support RS-485, where up to 15 systems
may be networked.

2.2 Sensing Response
Sensing response is a funcon of the number of beams interrogated (steps) per scan of the array. The me per step is 55 μs (0.000055
seconds). As a result, dense arrays (for example with 3/8 inch beam spacing) yield the highest sensing resoluon. Arrays with wider (3/4
inch) beam spacing oer faster sensing response.
2.3 Supplied System Soware
The supplied soware program, used to congure each System control module, may be run on any PC running Windows®The menu-
driven program walks the user through the many scanning and output opons. Aer the desired opons are selected, the user can save
the combinaon of selecons in a Parameter Setup File (PSF), and store it in the control module’s non-volale memory. Any number of
PSFs may be stored in the computer and recalled as needed.
The soware also provides alignment and diagnoscs rounes. An Alignment screen displays the individual status of each beam in the
light screen, as well as the total number of beams in the System, and totals of beams blocked, made, and blanked. Built-in system
diagnoscs can be used to assess emier and receiver hardware errors.

4 Installaon Instrucons
4.1 Emier and Receiver Mounng
Banner MINI-ARRAY emiers and receivers are
small, lightweight, and easy to mount; the mounng
brackets (supplied) allow ±30 degrees rotaon.
From a common point of reference, make
measurements to posion the emier and receiver
in the same plane with their midpoints directly
opposite each other. Mount the emier and receiver
brackets using the M4 x 0.7 x 14 mm bolts and
associated mounng hardware (all supplied).
Although the internal circuitry of the emier and
receiver can withstand heavy impulse forces,
vibraon isolators can be used instead of the M4
bolts to dampen impulse forces and prevent possible
damage from resonant vibraon of the emier or
receiver assembly. Two dierent An-Vibraon
Mounng Kits are available from Banner. See
Accessories on page 30.

1. Mount the emier and receiver in their mounng brackets (see Figure 2 on page 10).
2. Posion the red lenses of the two units directly facing each other. The connector ends of both sensors must point in the same
direcon.
3. Measure from one or more reference planes (that is, the oor) to the same points on the emier and receiver to verify their
mechanical alignment. If the sensors are posioned exactly vercal or exactly horizontal, a carpenter’s level may be useful for
checking alignment. Extending a straight-edge or a string between the sensors may help with posioning.
4. Also check by eye for line-of-sight alignment.
5. Make any necessary nal mechanical adjustments, and hand-ghten the bracket hardware.
6. Prepare the cables: The “drain wire” is the uninsulated stranded wire which runs between the cable jacket and the foil shield.
Remove the foil shield at the point where the wires exit the cable.

Wire the system power.
1. Connect a 16 to 30V dc source to controller terminals #1 (V+) and #2 (V–).
2. Connect a good earth ground to terminal #3.
A good earth ground is important for providing electrical and RF noise immunity to the MINI-ARRAY System. The dc power source must
supply 1.25 amps (worst case) when using the longest (6 ) sensors. See Specicaons on page 7 for more informaon.
4.6 Gate Wiring
Connect a switched 10 to 30 V dc source as a gang input (if required) between controller terminal #11 (+) and #12 (-). Voltage is
typically switched by the open-collector output transistor of a dc sensing device.

5 Conguraon Instrucons
5.1 Install the Soware
The Parameter Setup Soware CD includes an installaon program that quickly and easily loads the MINI-ARRAY conguraon program
into the computer. The MINI-ARRAY conguraon program requires approximately 50 MB of hard disk space. Install as follows:
1. Use the Parameter Setup Soware CD included with the controller, or download (www.bannerengineering.com) per the
following:
• For models MAC-1, MACI-1, MACN-1, MACP-1, and MACV-1, use CD P/N 75877
• For models MAC16N-1 and MAC16P-1, use CD P/N 75878
2. Insert the Soware CD into the CD drive.
• If the program does not auto-start, browse to your CD drive, click Setup.exe, then select START, then select RUN. The
Welcome dialog box appears. Select Next, and follow the prompts in the dialog boxes as they appear.
• If the program does auto-start, the Welcome dialog box appears. Select Next, and follow the prompts in the dialog boxes as
they appear.
3. The installaon program decompresses the les. A status dialog box monitors the progress of the installaon.
4. An Installaon Completed dialog box appears. Select OK. Reboot your computer for the changes to take eect.
Aer the soware is installed, a MINI-ARRAY shortcut icon is placed on your desktop. Double-click on the MINI-ARRAY icon to
launch the program, then follow the conguraon instrucons.
5.2 Dene the Communicaon
The MINI-ARRAY soware permits serial communicaon via RS-232 between the MAC controller and the PC. The minimum connecons
to the DB-9 connector on the MINI-ARRAY Controllers are listed in Serial Communicaon Wiring on page 15. DO NOT use a “null
modem” RS-232 cable.
To congure the COM port of the PC, follow these steps.
1. Select the Opons > Serial Port menu.
The program supports serial communicaon via the COM1-COM2 port of the computer.
2. Select either COM1 or COM2.
3. Check Save Sengs on Exit (if it is not already checked) to store the COM port selecon.
5.3 Alignment
Alignment status is connuously displayed by the green LED indicator on the Receiver and the controller.
When all unblanked beams are clear, and excess gain of all beams is more than 3×, the green alignment indicators are ON.
When the excess gain of one or more beams drops to between 3× and 1×, the green ALIGN LED on the controller remains ON, but the
yellow LED on the receiver comes ON to indicate a marginal alignment warning.
The MINI-ARRAY soware can display the status of each beam in the array. This is helpful for nal alignment or when analyzing how the
MINI-ARRAY is viewing objects in the sensing array. To use these feature, go to the Mini-Array > Alignment menu or press the F3 key.
The Alignment screen idenes the locaon of the rst and last beams made (clear) and broken (blocked), plus the total number of
beams made and broken. The beams are numbered in sequence from the cable end of the sensors to the top end. This is valuable
during setup, for analyzing exactly what is being seen by the light screen. (The Diagnoscs screen indicates any problems with the
emier or the receiver.)
Models MAC-1, MACP-1, MACN-1, MACV-1, and MACI-1—To display current informaon, select the desired Channel Status Opon
(Broken, Made or Both) and select Run. The chart on the right side of the screen shows the status (broken or made) of each beam in the
array. Beam status is connuously updated to allow accurate posioning of the array, and/or analysis of sensing response.
To exit the Alignment screen, rst select Stop, then select Exit.
Models MAC16P-1 and MAC16N-1—The Alignment screen displays the status of each beam along the enre length of the light screen.
The informaon displayed includes the total number of opcal channels (labeled as Beams), the number of blocked, made, and blanked
beams. Each channel state is indicated as either 1-made, 0-blocked, or B-blanked. Other alignment funcons allow the user to scan on a
step command and to adjust the blanking elds. Each channel can be individually blanked. When a channel is blanked, the controller
ignores the state of the channel and does not consider the channel when calculang measurement mode data.
5.4 Parameter Setup Files (PSFs)
The input and output response of the MAC controller is programmed using the PSF Conguraon screen. To access the PSF
Conguraon screen, go to Edit PSF under the Main menu or press the F4 key.
A-GAGE®MINI-ARRAY®Measuring Light Screen System

MACV-1, and MACI-1 PSF Conguraon Screen for Models MAC16N-1 and MAC16P-1
The soware included with the controller makes it easy to congure the MINI-ARRAY using your PC-compable computer. Simply install
the soware, launch the program, and access the Edit PSF Conguraon screen. Each opon is selectable using your mouse and the
pop-up menu-style selecons.
Alarm/Trigger—Output 2 may instead be programmed to serve as a trigger input for another MINI-ARRAY or ALARM for the self-
diagnosc circuitry.
Analog and Discrete Output Assignment—Assigns an analysis (measurement) mode to each output.
Analysis (Measurement) Mode Selecon—Choose the measurement opon that best tells you the size and/or posion of objects as
they relate to the array.
Blanking—Allows either 1 or 2 areas of the array to be blind to the acvity of the areas specied.
Control Mode Selecon—There are three modes to choose from:
•Connuous Mode: The controller constantly polls the array for status.
• Gate Mode: The controller polls the array for status when prompted by an input from a Gate sensor.
• Host Mode: The controller polls the array for status when prompted by a host controller.
Invert—Allows output to be normally open (No) or normally closed (Yes).
Scan #—Analog outputs are updated with an average value of the data received during the selected number of scans. Discrete outputs
respond only if the received data is idencal for all the selected number of consecuve scans. Values: 1 through 9.
Scanning Method—There are four scanning methods:
• Straight scan polls each beam sequenally to determine the target object's overall size. This is the most accurate and precise
measurement, but also the most me-consuming.
• Interlaced scan alternates a straight scan with a slanted beam scan to improve opcal resoluon in the center one third of the
sensing range.
• Edge scan acvates only the beams located near the top edge of the object in the light screen to reduce the sensing response
me.
• Skip scan skips one to seven beams to reduce the response me. Minimum object detecon size increases proporonally to the
number of beams skipped.
Serial Communicaon—Changes the idencaon and baud rate of the controller being congured.
Serial Transmission—Choose ASCII, binary, or no serial communicaon.
Set Point and Hysteresis Selecon—Assigns the set point to determine where within the array the output(s) will respond and the
hysteresis values to smooth the output response.

within PC les for quick controller conguraon whenever a conguraon change is required.
5.4.1 Assigning the Analysis Mode
The MINI-ARRAY controller is a versale microcontroller-based module that may be congured using a PC-compable computer running
Windows®and the Banner-supplied soware via the built-in RS-232 or RS-485 interface.
You may program one or two Measurement Analysis modes. Assign Meas1 or Meas2 to one or both outputs. The Banner MINI-ARRAY
System can be programmed for any one or two of the following Scan Analysis Modes:
All Data (ALL)—The controller passes all beam condion data for every scan to the serial interface for analysis by a host computer or
controller.
First Beam Blocked (FBB)—The controller idenes the locaon of the rst beam blocked. Beams are numbered, beginning with the
cabled end of the sensor, and connuing in sequence to the top end of the sensor.
Last Beam Blocked (LBB)—The controller idenes the locaon of the last beam blocked.
Total Beams Blocked (TBB)—The controller totals the number of blocked beams.
Conguous Beams Blocked (CBB)—The controller totals the number of conguous beams blocked in each group of blocked beams
along the length of the light screen and registers the maximum value.
First Beam Made (FBM)—The controller idenes the locaon of the rst clear beam.
Last Beam Made (LBM)—The controller idenes the locaon of the last clear beam.
Total Beams Made (TBM)—The controller totals the number of clear beams.
Conguous Beams Made (CBM)—The controller totals the number of conguous clear beams in each group of clear beams along the
length of the light screen and registers the maximum value.
Vehicle Separaon (VHS) (discrete output models only)—Controller output #1 is energized when six or more connuous inches of light
screen length are blocked (i.e., conguous beams blocked), and de-energizes when all beams are clear. This mode is typically used for
vehicle sensing in toll booth applicaons.
Segment (SEG) (controller models MAC16N-1 and MAC16P-1 only)—The controller segments the array into regions and allows the user
to paron the array. The user denes conguous segments. Once the segments are dened, the Controller monitors each segment for
blocked beams within each segment. If one or more beams are blocked within any segment, the output corresponding to that segment
will respond.
Transion (TRN) (controller models MAC16N-1 and MAC16P-1 only)—The controller counts transions, which are used to count
objects. This mode counts both clear-to-blocked and blocked-to-clear transions. For example, if an object blocks beams 20 through 30,
the TRN mode will count two transions. If an addional object blocks beams 35 through 40, then the TRN mode will count four
transions.

5.4.2 Conguring the Outputs
The controller oers 2, 3, or 16 outputs, depending on the model. One scan analysis mode may be assigned to Output 1 and a second,
dierent, analysis mode may be assigned to Output 2. All models except the 16-output models have an output labeled Alarm. This
output can be congured to:
•Funcon as the alarm output for the controller’s self-diagnosc circuitry when a scan analysis mode is not assigned to it; or
• Serve as a trigger input to begin the scan sequence of another MINI-ARRAY System.
Conguring the Discrete Outputs (MAC-1, MACP-1, MACN-1, MACV-1, and MACI-1)
Use the Output Assignments secon of the PSF Conguraon screen to customize the Analysis Mode(s) response. With the excepons
noted, either Meas1 or Meas2 can be assigned to Output 1 or Output 2.
Output 2 may be assigned as an Alarm output for the module’s self-diagnosc circuitry when a scan analysis mode is not assigned to it.
Output 2 can also be programmed to serve as a Trigger input to begin the scan sequence of another MINI-ARRAY System. The Trigger
value is the beam locaon along the array at which the Trigger output (during a scan) occurs.
Set Point (Low and High) determines where within the array the output(s) responds. In the case of total or conguous beams made or
broken, these sengs determine the minimum and maximum number of beams required for an output.
Hysteresis (Low and High) determines how much change must occur at each set point to cause the associated output to change state.
Hysteresis avoids unstable output condions (chaering) when the scanning condion exactly matches one of the set points. The
default seng for hysteresis is one beam less than the Low Set Point and one beam more than the High Set Point.
Scan # is the number of consecuve array scans required before the associated output is updated. The controller can be programmed
for from one to nine consecuve scans. The scan data MUST BE THE SAME for all consecuve scans before the associated output
updates.
Invert (Y/N) allows the output to be normally open (No) or normally closed (Yes).

Conguring the Discrete Outputs (MAC16P-1, MAC16N-1)
Congure the 16 discrete outputs using the Outputs buon on the Mulple Output MINI-ARRAY PSF Conguraon screen.
The Outputs buon launches the Edit Discrete Outputs screen, which allows the Set Points and Hysteresis levels to be dened for each
output. Set Point and Hysteresis values may be congured individually for each output and assigned to either Meas1 or Meas2.
Set Point level denes the condion where the output is in the “true condion”. For a typical applicaon, the output will be acve when
the Measurement mode result is between the set point limits. If the inverted opon is specied, the output will be inacve when the
Measurement mode result is between the set point limits (i.e., the true condion).
The Hysteresis Low and High levels determine when the output changes back to the false condion.
The SEG measurement mode uses the Set Point Low and High levels to dene segmentaon of the light screen. As an example, Output 1
Set Point Low is 5 and the Set Point High is 20. These two values dene beams 5 through 20 as a segment. When any of these beams are
blocked, this segment of the light screen is considered blocked, and Output 1 is acve (or inacve, if “Inverted” is selected). For the SEG
measurement mode, the Hysteresis specicaon is inacve.
The Scan Number may be used to change the number of consecuve scans necessary to change the output. When the Scan Number is
set to one, the output changes aer only one scan. If the Scan Number is set to ve, the outputs do not change unless the condion is
true for ve consecuve scans.
Conguring the Analog Outputs (MACV-1 and MACI-1)
The MACV-1 and MACI-1 Controllers oer two independent analog outputs.
For Analog Output 1 and Analog Output 2, each output is assigned to one of six analysis modes, which are selected using the Edit PSF
screen.
1. Specify the Analysis Mode Selecon for Meas1 and Meas2
2. Specify the Analog Output using the Analog Output choices. The analysis mode is selected as Meas1, Meas2, or Disabled.
• Disabled: Output is not used
• Meas1 and Meas2: Reect the choices provided with the Analysis Mode Selecon
3. Dene the number of scans (Scan #) to average before the analog output updates. Accepted values are 1 through 9.
4. If desired, select the Invert opon to change the output from a rising signal to a falling signal.
Null/Span Adjustment—The user can adjust both the zero and full-scale reading for both analog outputs of MACV-1 and MACI-1
Controllers. This adjustment is implemented via the Edit PSF screen Null/Span buon, which acvates the Null/Span menu. The Null/
Span menu causes the controller to temporarily respond to scaling adjustments. The Null and Span ranges can be adjusted as follows:
