6.
Keep the match code in the illumination line at following reading distances:
ICR 840 (standard type) : 80 mm (3.15 in) for side/front reading window.
The ICR confirms that the read was successful by emitting a tone and then ends the
reading interval. Match code 1 is now stored in the RAM.
7.
Close the switch
to reconnect the power supply to the “Sensor 2“ switching input.
The ICR saves match code 1 (bar code type, code length and data content)
permanently in the parameter set stored in the EEPROM.
It compares every bar code it reads with match code 1 until the power supply is
switched off. In doing so, it outputs the result of the comparison via the “Result 2“
output and “Result“ LED with the predefined pulse length.
If the ICR was not able to read the match code, the reading interval is terminated when
the switch is closed. The previously set code configuration remains unchanged.
8.
Keep the switch closed
.
The ICR will activate teach-in mode again if you open the switch!
Replacing the match code:
To replace the current match code 1 with a new match code using the teach-in method,
simply repeat steps 5 to 7.
Checking the programmed match code in the ICR:
Proceed as described in Steps 1 to 3 in

EACH
-
IN
Activating the code comparison function:
1.
Close the switch before switching on the power supply to the ICR.
2.
Switch on the supply voltage.
The ICR activates the code comparison function.
3.
Do not open the switch while the ICR is starting up.
Deactivating the code comparison function:
1.
Switch off the power supply to the ICR.
2.
Open the switch.
3.
Switch on the supply voltage.
The ICR starts Reading mode without the code comparison.
Assigning result functions to the “Result 1“, “Result 2“ (“Result“ LED) switching
outputs and beeper
The ICR can output the result of the code comparison in the following functions:
–
No match (code does not match either match code)
–
Match 1 (matches match code 1)
–
Mismatch 1 (does not match match code 1)
–
Match 2 (matches match code 2)
*)
–
Mismatch 2 (does not match match code 2)
*)
–
Match 1 or 2 (matches match code 1 or 2)
–
Match 1 and 2 (matches match code 1 and 2)
*)
*)
only relevant if match code 2 is active
