A-GAGE EZ-ARRAY
QuickStart Guide
Overview
1.4 Status Indicators
Both the emitter and receiver provide ongoing visual indication of
operating and configuration status.
The emitter has a red LED that signals proper operation (ON
when power is applied).
The receiver has a bright Status LED that indicates overall
sensing status (OK, marginal alignment, and hardware error).
Two other LEDs indicate whether serial communication is active
or if there is a communication error. Seven Zone indicators each
communicate the blocked/aligned status of one-seventh of the
total array. A 3-digit diagnostic display provides further diagnostic
information: number of beams blocked, whether blanking is
configured, and troubleshooting codes. See Section 4.6 for
display codes and troubleshooting.
Zone Indicators (Beams Blocked Segment)
Seven LEDs represent emitter/receiver alignment status. They
provide a visual aid for sensor alignment and monitoring objects
within the sensor’s field of view. The sensor array is partitioned
into seven equal segments, each of which is represented by
one of the seven LEDs. The LED closest to DIP switch S6 (see
Figure 4-1) represents the group of optical channels closest to
the receiver display (the “bottom” group). The LED closest to DIP
switch 1 represents the far segment of channels.
These LEDs illuminate either green or red. When an LED is
green, no unblanked beams are obstructed in that segment.
When the LED is red, one or more beams in that segment is
obstructed.
1.3 System Components
A typical A-GAGE EZ-ARRAY has four components: emitter and
receiver, each with an integral quick-disconnect (QD) fitting, plus
an 8-pin QD emitter cable, and one for the receiver (see Figure
1-3). 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. (A PC used for configuration must run
on Windows ® XP or 2000.)
Sensors are available in 10 array lengths from 150 to 1800 mm
(see Section 2-1). The emitter has a column of infrared light
emitting diodes spaced 5 mm apart; the light is collimated
and directed toward the receiver. An identical length receiver,
positioned opposite the emitter, is populated with photodiodes
on the same 5 mm pitch. The light from the emitter is focused
on, and detected by, the receiver. 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).
