A-GAGE EZ-ARRAY
QuickStart Guide
Overview
• Inside Dimension (ID): This measurement returns the value of
the beams made between the first beam and last beam blocked.
• Contiguous First Beam Blocked (CFBB): This measurement
returns the value of the first beam blocked in the largest group
of contiguous beams blocked.
• Contiguous Last Beam Blocked (CLBB): This measurement
returns the value of the last beam blocked in the largest group
of contiguous beams blocked.
• Special 1, Special 2, Nap: These measurement modes are
reserved for future capabilities.
1.11 Analog Output Configuration
Analog output configuration assigns analog outputs 1 and 2 to
one of the measurement modes described in Section 1.10. When
the selected measurement mode involves first or last beam
blocked or made (unblocked), the assigned output will vary in
proportion to the beam number identified during a scan. When the
measurement mode involves total beams blocked or made, that
assigned output will vary in proportion to the total beams counted
during a scan.
Analog outputs may have Null and Span values set in the GUI, in
addition to a filter setting (to smooth the output) and Zero Value
(to specify the output value when the measurement mode value is
zero). See Section 5 for more information.
1.12 Discrete Output Configuration
Discrete Output 1; Receiver Interface
When the receiver interface is used for configuration, the
measurement mode assigned to discrete output 1 is the same as that
assigned to analog output 1. Whenever the analog output detects a
target present, discrete output 1 conducts (normally open).
Discrete Output 2; Receiver Interface
Discrete output 2 (only) has two options: alarm and
complementary (measurement) operation.
Alarm: Output 2 energizes whenever the receiver detects a
sensor error (such as a disconnected cable) or whenever the
excess gain of one or more beams becomes marginal.
Complementary (Measurement): Discrete output 2 operation is
complementary to discrete output 1 ( when output 1 is ON, output
2 is OFF, and vice versa).
Discrete Output Configuration; Software Interface
When the software interface is used for configuration, the discrete
outputs have other options: either discrete output can be assigned
to any of the measurement modes, high and low set points can
be added, the outputs can be inverted, and hysteresis values can
be set, as well as a scan number to smooth output performance.
Discrete output 2 can be assigned to alarm mode via the GUI
also. See Section 5 and the Appendix of the full manual for more
information.
1.13 Serial Communication
The receiver communicates with a process controller via a modbus
RTU-485 interface and at the baud rate specified in the Serial
Communications box of the GUI. A number of data transmission
options are available, including what data will be sent, and when.
See Section 5 and the Appendix of the full manual for more
information.
