2 System Overview
The A-GAGE
®
High-Resolution MINI-ARRAY
®
measuring light screen is ideal for applications such as on-the-fly product
sizing and profiling, edge-guiding and center-guiding, loop tensioning control, hole detection, parts counting and similar
uses.
A typical A-GAGE High-Resolution MINI-ARRAY system has five components: a high-resolution emitter/receiver pair, each
with quick-disconnect (QD) connectors; one of four compact control modules; and quick-disconnect cables to connect
them. Software is included to interface any PC-compatible computer (running Windows
®

XP, Vista, or 7) with the control
module for system configuration. A host computer or PLC may be used to control and/or receive input from the system.
Sensors are available in twelve array lengths from 163 mm to 1951 mm (6.4 in to 76.8 in), in 163 mm (6.4 in) increments. The
emitter has two columns of infrared LEDs spaced 5 mm (0.2 in) apart. The columns are separated by 7.5 mm (0.3 in) and are
staggered from each other by 2.5 mm (0.1 in). The receiver is configured opposite to the emitter, with the identical length
and beam spacing. This high-resolution sensor pair is capable of detecting a 12.7-mm long by 2.54-mm diameter (0.5 in by
0.1 in diameter) cylindrical rod (held perpendicular to the sensor). The sensors have a wide field of view and are easily
aligned, with a working range of 380 mm to 1.8 m (15 in to 6 ft).
Each of the four versatile microcontroller-based control modules are configured using a PC-compatible computer running
Windows XP, Vista, or 7, and the supplied software, via the built-in RS-232 interface.
2.1 System Features
Built-in features simplify the operation of the A-GAGE High-Resolution MINI-ARRAY system. High-resolution emitters and
receivers, available in twelve lengths, feature two closely spaced columns of beams to provide a precise, high-resolution
light screen for exacting applications. The Alignment routine automatically equalizes the excess gain of each beam for
reliable 2.5-mm (0.10-in) object detection throughout the array and stores this data in non-volatile memory. The Alignment
routine does not need to be performed again unless the sensing application changes, or if the emitter and/or receiver is
moved. Programmable beam blanking accommodates machine components or other fixtures that must remain in or move
through the light screen. Blanking may be set automatically as part of the initial setup, or by using the included
configuration software.
Built-in diagnostic programming and easy-to-see indicators on the sensors and the control module make alignment and
troubleshooting easy. The emitter has a red LED that signals proper operation. 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
condition. The control module has four status indicators: 3 red LEDs signal discrete output #1 conducting, Alarm output
(discrete output #2) conducting, and gate signal received; a green LED signals that the sensors are properly aligned. A
segmented LED Diagnostics Indicator provides detailed system status using single-digit codes; a period in the indicator
window indicates the presence of blanking. A key to the diagnostics codes is printed on the side of the control module for
simplified troubleshooting.
The A-GAGE High-Resolution MINI-ARRAY system provides a wide selection of sensing and output options, including:
measurement (scan analysis) modes and scanning methods that can determine the target object’s location, overall size,
total height or total width. Scanning may be continuous or controlled by a host process controller or a gate sensor. Up to 15
systems may be networked.
