Before the external teach-process can be started, the color to be taught must be presented to the sensor.

The external teach process is started with a positive edge at IN0 (green wire). When such a positive edge is

applied, the output LEDs (OUT0 ... OUT4) start to blink. From now on, the user has a certain number of seconds

time to inform the sensor about the position at which the color information (X,Y,INT) should be placed in the

TEACH TABLE. The period of time, in which the user can teach the color information to the sensor depends on

the value that is set in MAXCOL-No. (e.g. approx. 5 seconds when MAXCOL-No. = 5).

The first positive edge (start edge 0) selects position 0 in the TEACH TABLE.

Every additional positive edge selects one position higher (see table below).

Example:

If you wish to save the current color to position 3 in the TEACH TABLE, the following steps have to be performed:

1. Start of the external TEACH process with a positive edge (0) at IN0 Æ Position 0 is selected, the LEDs

start to blink.

2. An additional positive edge (1) selects position 1 in the TEACH TABLE. This position 1 is indicated by

the LEDs. The LED with binary value 1 remains on HIGH level all the time, while the other 3 LEDs

continue to blink.

3. An additional positive edge (2) selects position 2 in the TEACH TABLE. This position 2 is indicated by

the LEDs. The LED with binary value 2 remains on HIGH level all the time, while the other 3 LEDs

continue to blink.

4. An additional positive edge (3) selects position 3 in the TEACH TABLE. This position 3 is indicated by

the LEDs. The LEDs with binary value 3 remain on HIGH level all the time, while the other 2 LEDs

continue to blink.

5. The desired position is now selected.

6. When the BUSY window is over (the LEDs stop to blink), the sensor starts the evaluation.
