Appendix
Meaning of the "Sensor 2" switching input for Teach-in/ activation of code comparison
For teaching in match code 1 via the "Sensor 2" switching input, a switch must be connected
(
Fig. 10-17
) and the functional assignment of the switching input, the teach-in mode and, if
necessary, other settings must be done with the CLV-Setup configuration software.
With the help of the switch on the "Sensor 2" switching input, the ICR845-2 triggers the
teach-in for match code 1 und starts the code comparison as followed:
After switching on the power supply while the switch has been closed, the ICR845-2
starts teaching-in the match code 1 via its optical interface (reading window) when the
switch will be opened. When closing again the switch, the ICR845-2 saves the recorded
match code 1 permanently in its parameter memory (code type, code length, and code
content). To do so, the ICR845-2 overwrites an already existing match code 1.
If the match code 1 is to be saved also permanently in an external parameter memory
module CMC600 (for consistent parameter set in the ICR845-2 and in the external me-
mory) you must set this option in the CLV-Setup configuration software. The option is
only available in Static Teach-in mode.
After the teach-in procedure for match code 1 has been successfully completed, the
ICR845-2 automatically starts the code comparison for futher readings. This temporary
state will remain until the power supply is switched off or the switch on the "Sensor 2"
switching input is opened again during operation.
If the dynamic teach-in of match code 1 has not been sucessfully, the ICR845-2 will eit-
her use the last saved match code 1 or will not compare any code (depends on the set-
ting in CLV-Setup).
