A-GAGE EZ-ARRAY
QuickStart Guide
Overview
Figure 1-2. A typical A-GAGE EZ-ARRAY application
The emitter has a red LED that signals proper operation (ON
when power is applied). See Section 1.4 for more information
about indicators and Section 4.6 for display codes and
troubleshooting.
The Alignment routine (Section 4.2, or Section 5 of the full
manual) automatically equalizes the excess gain of each beam
for reliable object detection throughout the array. The Alignment
routine need not 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 using the receiver
interface, the teach wire or the GUI.
The EZ-ARRAY light screen provides a wide selection of
sensing and output options, including measurement (“scan
analysis”) modes and scanning methods that can determine
a target object’s location, overall size, total height, or total
width, or the number of objects. Scanning may be continuous
or controlled by a gate sensor. Up to 15 systems may be
networked, via modbus; see Section 5 or Appendix A of the full
manual.
1.2 Configuration via DIP Switch or Supplied Software
Commonly used configuration options can be set up easily via
a six-position DIP switch located behind a hinged clear access
panel on the front of the receiver.
Access to the DIP switch can be prevented by using the screw-
on security plate to hold the clear access panel closed or by
disabling them via the GUI.
For more individualized (advanced) applications, the supplied
GUI software program (which runs on a PC-compatible
computer running Windows ® XP or 2000; see Section 5 of the
full manual for more information) may be used to configure the
receiver. The menu-driven program walks the user through the
many scanning and output options. After the desired options are
selected, the combination of selections can be saved in an XML
file, stored in the system configuration computer and recalled as
needed.
The software also provides alignment and diagnostics routines.
An Alignment screen displays the individual status of each beam
in the light screen, as well as the total number of beams, and
totals of beams blocked, made and blanked. Built-in diagnostics
can be used to assess emitter and receiver hardware errors.
(See Section 5.)
Outputs
All models have two analog outputs and two discrete outputs. An
additional serial output communicates to the PC via a modbus
RTU-485 interface.
The analog outputs are either 4–20 mA current or 0–10V voltage,
depending on model (see Section 2-1). They may be configured
(via DIP switch or software) for either a positive or negative
slope.
Discrete output 2 is selectable (via DIP switch or software) for
alarm or measurement operation. When the receiver interface is
used, discrete output 1 follows the operation of analog output 1
(it conducts when the analog output senses a target is present).
When the GUI is used for configuration, both discrete outputs
have full configurability, including measurement mode, NPN or
PNP polarity, and normally open or normally closed operation.
Gain Setting
The receiver can be set for either high-excess-gain or low-
contrast operation, depending on the quality of the sensing
environment, necessary sensing range and the opacity of the
sensed target (see Section 4.3). For low-contrast operation, only
a portion of each beam must be blocked for detection to occur.
Display Invert
For applications where the sensors must be inverted (and thus
the display is not right-reading), the receiver offers a display
invert feature, which inverts the diagnostic display for easy
reading (see Section 4.4).
