7. In the dialog box under RESULT FUNCTIONS, choose MATCH 1 in the drop-down list for
Result 2 ("Result" LED).
8. Perform a download to the CLV. This is done by clicking in the toolbar.
9. Confirm the dialog box by selecting the PERMANENT save option.
Note Before you can use the static teach-in method, the parameter sets in the RAM and EEPROM
of the CLV must be identical. This is done with the
PERMANENT saving option. If you select the
TEMPORARY option instead, the CLV loads the default settings after the teach-in function has
been carried out and the power supply switched off.
Carrying out the static teach-in procedure:
1. Click in the toolbar.
The terminal emulator is launched. The CLV is in Reading mode.
2. Close the switch to connect the power supply to the "Sensor 2" switching input.
3. Click PARAMETERIZE under DEVICE MODE.
The CLV switches to Parameter mode.
4. Click READING MODE under DEVICE MODE.
The CLV returns to Reading mode and polls the condition of the "Sensor 2" switching
input. It also activates code comparison at this time.
– or –
As an alternative to steps 3 and 4, switch the power supply to the connection module (of
the CLV) off and on again. The CLV outputs two consecutive tones to indicate that it has
switched to Reading mode.
5. Open the switch to interrupt the power supply to the "Sensor 2" switching input.
The CLV activates teach-in mode for match code 1.
It starts the reading interval automatically and waits for the match code.
6. Present the match code.
The CLV 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 CLV saves match code 1 (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 CLV was not able to read the match code, the reading interval is terminated when
the switch is closed. The previously set code configuration remains intact.
8. Keep the switch closed.
The CLV 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 CLV:
Proceed as described in steps 1 to 3 in "a) Dynamic teach-in procedure", Page 10-28.
