Teach in the first intensity value:
• Set the rotary selector switch
Ý
to
TEACH DUAL
• Align the Sensor spot to the marking
• Press and hold the plus key
è
The LED at the plus key lights up
è
The LED at the plus key goes out after 1 second and the output switching status indicator A blinks
• The LED at the plus key lights up
è
The LED at the minus key blinks
è
The intensity value of the marking is saved to buffer memory
Teach in the second intensity value:
• Align the Sensor spot to the background
• Briefly press the minus key
and then release
è
The switching threshold is calculated and saved to memory
è
The LED at the minus key stops blinking
• Check for correct function
If the difference between the two acquired intensity values is too small, the output switching status indicator
A
blinks rapidly for approximately 3 seconds, and switching thresholds are not updated.
Dynamic Teach-In
All intensity values from the background and the marking are continuously acquired with this function. The
ideal switching threshold is calculated based upon these values.
This function is intended for applications where the objects to be scanned move continuously at a constant
speed, and cannot be brought to a standstill within the production process.
Example 1:
Recognition of luminescent adhesive strips on unprinted packaging material, which is
fed in a continuous fashion: when Teach-In operation is initialized, the spot must be
aligned to the background.
Example 2:
Recognition of luminescent markings on rapidly rotating parts: dynamic Teach-In
operation can be initialized regardless of spot alignment.
Initialise recording mode operation:
• Set the rotary selector switch
Ý
to
TEACH DYN
• Press and hold the plus key
è
The LED at the plus key lights up
è
The LED at the plus key goes out after 1 second and the output switching status indicator A blinks
• Release the plus key
è
The LED at the minus key blinks: recording mode operation is active
è
Intensity values are continuously recorded
Exit recording mode operation:
• Briefly press the minus key
and then release
è
Recording is stopped
è
The switching threshold is calculated and saved to memory
• Check for correct function
If the difference between the two acquired intensity values is too small, the output switching status indicator
A
blinks rapidly for approximately 3 seconds, and switching thresholds are not updated.
