WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.
Overview
The D10 Expert Small Object Counter sensor is a high-performance plastic
fiber optic amplifier that has been optimized for small object counting
using through-beam fiber optic arrays. Fiber optic arrays emit and receive
light over an area instead of a narrow beam. Having an area of light
makes alignment and positioning control of the object less critical than
using single point emitter and receiver fiber optic assemblies. Because the
object only breaks part of the fiber optic array, reliable detection requires
very precise thresholds, an auto compensation tracking algorithm, and
high speed electronics to make split-second decisions.
The setup and configuration of the advanced D10D sensor has been
reduced to the act of applying power to the device with the fiber optic
assemblies rigidly mounted in position. The user also has access to a
comprehensive collection of setup and configuration parameters through
the sensor’s advanced setup menu, but for most applications the default
options provide superb performance and reliability.
Upon power-up, the clear-state light level is measured and appropriate
switching thresholds are established, making the fiber optic sensor
system a stable, fast, and reliable small object counter. The clear-state
light level can be reset by performing a 2 second hold on the dynamic (+)
push button or single-clicking the remote line.
Continued reliable operation is ensured as the thresholds adapt to
changing signal levels over time using Banner Engineering’s auto
compensation tracking algorithm. The sensor continuously tracks the
clear-state light level and makes fine adjustments to the switching
thresholds as required because of dust or contamination building up on
the fiber optic array and for ambient temperature changes.
The sensor features either two NPN or two PNP outputs, depending on
your model. Each output serves a different purpose. The discrete output 1
(white wire) switches whenever an object breaks the fiber optic array and
can be used for counting. The Health Mode output 2 (black wire) switches
when the fiber optic array becomes contaminated to a point that the auto
compensation tracking algorithm cannot sufficiently adjust the thresholds
to ensure reliable detection (see Health Mode Alarm on page 3).
The duration of the discrete output 1 (white wire) can be increased
(stretched) to ensure accurate counting. The amount of increase is a user
configurable percentage of the detection event duration; the default
increase time is 50% more than the event duration. Banner calls this
feature a Dynamic Event Stretcher (DES), and it prevents errant double
counts of translucent gel-caps and other small objects of that type. The
DES provides a “smart” OFF-delay that is independent of application
speed and can be adjusted from 0% to 100% of the detection event
duration.
