Bar Graph Display

In order to make adjustment easy, the CS2 contains its own
voltmeter with a bar graph display which is visible through
the top. This display uses a "moving dot" technique where
the segment position represents the amplitude of the
reflected light.
Output Bar Graph Display
Green
Yellow
Bright bar indicates Sense Color
The lowest voltage segments are yellow, the center green,
and the highest are red. Usually, once the Gains are
adjusted, the background intensity will be no higher than the
yellow segments and normal objects will be in the green
range. The 10th (red) segment indicates an overrange
condition; at this point the readings are invalid. The Gains
need to be set such that the highest intensity is not higher
than the 9th segment.
Both the Base color and the Sense color are simultaneously
displayed using a different intensity for each color. The
brighter LED represents the Sense color.

Status Indicators

Four indicators provide status of the digital inputs and
outputs. Indicators are lit when the condition they represent
is true (Output NPN transistor ON).

Inputs and Outputs

The CS2 provides two analog and three digital outputs and
two analog inputs. The digital outputs are: Data Ready,
Base Limit and Sense Limit. All three are optically isolated
uncommitted NPN open-collector outputs.
The two analog outputs provide voltages proportional to the
real time Base color and Sense color. Updated every scan
cycle, the outputs range from 0-10V and will drive high
impedance inputs (2 kohms or higher). These outputs are
not temperature compensated and must be used with the
appropriate software algorithms.

Note 1. When using an external trigger, the Scan Cycle Time is
determined by the time between RPG transitions ( RPG NPN output
changes from OFF to ON). If the time between transitions is less
than the Trigger Delay Time, scan data will be lost.
