Operation
colorSENSOR CFO
Trigger input High level No function,
Switch outputs,
Teach color,
Sensor keys,
Run autogain,
Remove all colors,
Remove all color groups
and colors
Determines one or several functions that
are executed when a trigger event occurs.
The following trigger events are possible:
Level High, Level Low, Rising edge, Fall-
ing edge
Low level
Rising edge
Falling edge
No function
Switching the outputs
The signal at the outputs is updated when the corresponding input sig-
nal is set. For example, if the outputs are switched when the signal level
is high, the update will continue as long as the level is present.
i
The measured values are sent via the interfaces at 15 Hz regard-
less of this setting.
Teaching
colors New
color group Here, a new color group with the color currently detected by the sensor
is created for each trigger event.
Output
(color group) Here, the new color is learned to the color group with the selected
output configuration, regardless of whether this color group already ex-
ists or not. This allows, for example, to always learn the color to output
1 (OUT0 on high). With this setting, you can then additionally select
whether all previous colors in this group should be deleted beforehand
or whether additional colors should be learned.
Color group:
#Name If color groups have already been learned, then colors can also be
taught to an existing color group. All color groups that have already
been learned can be selected under this function. If no color group has
been learned yet, this function is not available for selection. With this
setting, you can also select whether all previous colors in this group are
to be deleted beforehand or whether they are to be added.
Sensor keys Unlock Here, the
Membrane keypad
on the controller is unlocked with the cor-
responding trigger signal.
Lock In this case, the keyboard is locked when the corresponding trigger
signal is received.
i
Locking the keypad is recommended, as the controller is then
protected against unintentional adjustment.
Automatic modulation Here , see 5.6.3.3 , the controller settings are adjusted depending on the
measurement frequency and the detector modulation.
Delete learned colors This function deletes all learned colors in all color groups. However, the
color groups remain.
Delete learned color groups and
colors This function deletes the complete color table.

Trigger Type Selection Meaning
Level: High (H; 1) or Low (L; 0) State is present at the input for a longer period.
H High, is live and logical 1
L Low, logical 0
Low level As long as a low level < V
+
/2 ±5 % is present at the input, the
stored function is executed.
High level As long as a high level > V+/2 ±5 % (max. 30 V) is present at
the input, the stored function is executed.
When the state changes from Low to High or from High to Low, signal edges occur. These are meaningfully
referred to as positive or negative edge-triggered.
Rising edge Change of state between L (< V
+
/2 ±5 %) to H (> V
+
/2 ±5 %). During this change, the
stored function is executed.
Falling edge Change of state between H (> V
+
/2 ±5 %) to L (< V
+
/2 ±5 %). During this change, the
stored function is executed.
