A-GAGE EZ-ARRAY
Instruction Manual

1. Overview

The A-GAGE™ EZ-ARRAY™ measuring light screen is ideal
for such applications as on-the-fly product sizing and profiling,
edge-guiding and center-guiding, loop tensioning control, hole
detection, parts counting, and similar uses (see Figure 1-1).
Emitters and receivers are available with arrays from 150 to
2400 mm (5.9" to 94.5") long. The emitter has a column of
infrared light emitting diodes (LEDs) spaced 5 mm apart; their
light is collimated and directed toward the receiver, positioned
opposite the emitter, which has photodiodes on the same
5 mm pitch. The light from each emitter LED is detected by the
corresponding receiver photodiode.
This sophisticated light curtain is capable of detecting opaque
cylindrical objects as small as 5 mm in diameter or measuring
part edges within 2.5 mm, depending on the scanning method
selected (see Section 1.6). The sensing range is 400 mm to 4 m
(16" to 13').
The EZ-ARRAY's two-piece design makes it economical and
easy to use. Controller functionality is built into the receiver
housing. It can be configured for many straightforward
applications simply by configuring the six-position DIP switch on
the front of the receiver (the receiver user interface). For more
advanced control, easy-to-use PC interface software is available
on the included CD to configure the sensors using a PC.

Installation is easy, too. The emitter and receiver housings can
be side-mounted or end-cap-mounted using the included end-
cap brackets; longer models also include a center bracket (see
Section 3.1).
Beam synchronization is achieved via the 8-conductor sensor
cables. Individual LEDs and a 3-digit diagnostic display on the
receiver provide ongoing visual sensing status and diagnostic
information. Comprehensive data is available to a process
controller via a combination of five outputs: two analog, two
discrete, and one Modbus 485-RTU serial.

1.1 System Components

A typical A-GAGE EZ-ARRAY has four components: an emitter
and a receiver, each with an integral quick-disconnect (QD)
fitting, plus an 8-pin QD cordset for the emitter and for the
receiver (see Figure 1-2). For applications that use the Modbus
RTU-485 interface, an additional 5-wire cable is used to connect
the receiver with a PC or process controller, via the Modbus
485-RTU connection. (A PC used with software version 1.1
for configuration must run on Windows
version 1.2, when available, will be compatible with Vista
