A-GAGE EZ-ARRAY
Instruction Manual
Receiver Interface
The receiver user interface comprises the six-position DIP
switch, two push buttons, 3-digit display, and other indicators
present on the receiver (see Section 1.4 for more complete
status indicator information). The receiver interface enables
configuration of standardized combinations of the EZ-ARRAY
sensing options (output configuration, scanning methods and
modes); for more advanced setup, refer to Section 5 for PC
interface configuration instructions.
4.1 Configuration DIP Switch
The DIP switch can be used to configure the sensor. Access the
switch by removing the screw-on security plate and lifting the
clear hinged access cover. The access cover may be removed
entirely (pull straight out to remove, press back in to replace) for
easier access during configuration.
Some of the switches are assigned their own functions, others
work together in combination (see table). Switches S1 and S2
in combination select one of four scanning modes. Switches S3
and S4 in combination select one of four measurement mode
pairs (one for each analog output). Switch S5 defines the analog
slope setting for both analog outputs and S6 defines whether
discrete output 2 is complementary to discrete 1, or functions as
an alarm (when configuration is accomplished via DIP switch,
discrete output 1 conducts when analog output 1 senses the
presence of a target).
Scanning Modes (S1 and S2)
Straight Scan (S1 ON, S2 ON) is the most versatile scanning
mode and can be used without the exceptions noted in the
other scanning modes. Use this scanning mode when using
the low-contrast sensitivity setting to measure semi-transparent
materials.
Double-Edge Step 1 (S1 ON, S2 OFF) can be used when
three or fewer opaque objects are presented to the light curtain
at one time. The advantage of this mode is improved sensor
edge resolution (2.5 mm). The minimum object detection size is
10 mm.
Double-Edge Step 4 (S1 OFF, S2 ON) can be used when three
or fewer opaque objects are presented to the light curtain and
the minimum size object to be detected is 30 mm. This scanning
mode ignores objects smaller than 30 mm. Like Double-Edge
Step 1, the sensor edge resolution is 2.5 mm. See Figure 1-8 for
sensor scan times.
Single-Edge Scan (S1 OFF, S2 OFF) can be used when a
single opaque object is presented to the light curtain at one time.
The object must block the “bottom” channel (the channel closest
to the receiver display). Like the double-edge scans, the sensor
edge resolution is 2.5 mm. The minimum object detection size is
10 mm. See Figure 1-8 for sensor scan times.
