Connecting the "Result 1" to "Result 4" switching outputs
The four switching outputs can be assigned different functions for outputting result statuses
independently of each other. If the assigned event occurs during the reading procedure, the
corresponding switching output becomes live at the end of the reading pulse for the select-
ed pulse duration. The pulse duration can be set individually for each output.
The "Read Result" LED is linked to the "Result 2" output and lights up in Reading mode for the
selected pulse duration and function of the result status display (default: Good Read, 100 ms).

contains the character-
istic data for these outputs. The four outputs have the same characteristic data.

Connect the outputs as shown in
.
Note
In the
CDB420
Connection Module only the signals of the "Result 1“ and "Result 2“ switch-
ing outputs can be connected using the terminal strips.

Note
If the "Device Ready" function is chosen, the CLV490 outputs a static pulse in Reading
mode.
