A-GAGE EZ-ARRAY
Instruction Manual
Overview
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.
Three-Digit Display
The 3-digit display has slightly different functions during normal
operation, alignment, and gain adjust modes. In normal operation
the display indicates current numerical value of the measurement
mode for analog output 1. The display also identifies the
following activated sensor functions: blanking and locked-out
user interface/electronic configuration, as shown in Figure 1-4.
(For directions for inverting the display, see Section 1.5 or 5.8.)
During blanking mode, the display reads “
n
”, followed by the
number of blocked beams in the array. During alignment mode, it
reads “
A
”, followed by the number of blocked, unblanked beams;
a period follows the A (“
A.
”) if blanking is configured.
During gain adjust mode, the display reads “
l
” followed by “
1
” or
“
2
” to indicate the gain level. (A “
1
” represents high excess gain,
and a “
2
” represents low contrast.)
If a sensing error occurs, the display reads “
c
” followed by a
number that corresponds to the recommended corrective action
(see Section 4.5).
Blanking Indicator
The Blanking indicator will be visible (ON) when the blanking
feature is enabled. It appears as a period following the first digit
of the display.
Electronic Configuration Indicator
The Electronic Configuration indicator is ON when the sensor
configuration is defined by the PC interface, and not the DIP
switch and push buttons. When electronic configuration is
enabled, the DIP switch and push button settings are ignored.
sensors and a PC is accomplished via the serial output and
Modbus RTU-485 interface.
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 status.
Outputs
In addition to the serial output (see above), all models have two
analog outputs and two discrete outputs.
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 PC interface) for either a positive
or negative slope.
Discrete output 1 is always used for measurement; discrete
output 2 may be used either for alarm or measurement
operation (selectable via DIP switch or PC interface). 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 PC interface is used for
configuration, both discrete outputs have full configurability,
including measurement mode, NPN or PNP polarity, and
normally open or normally closed operation.
Display Invert
For applications where the sensors must be mounted with the
display end at the top (so that the display is not right-reading),
the receiver’s diagnostic display can be inverted for easy
reading, either by use of the receiver’s remote wire (Section 1.5)
or the PC interface.
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
4.5 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
