Counting Objects
Each light curtain is delivered preconfigured, so that it is ready for use immediately: Counting channel 1
counts objects that are larger than the minimum required object size for this device, e.g. objects from 1mm
in size. Output 2 (pin 7 on the D-Sub connector) is linked to channel 1 and its polarity is positive. The opto-
coupler of the output outputs a 10ms pulse after an object detected by this channel has left the sensing area,
i.e. it is conductive for 10ms.
Now hold an object, e.g. a ballpoint pen, in the sensing area for a short time. You must pay attention that you
do not cover the sensing area for longer than one second, as the maximum permitted passing time is set to
one second at delivery. If you stay longer in the sensing area, the monitoring is activated and an appropriate
entry will be created in the fault memory. The CMT displays the error message directly in a separate window.
In addition, the error message can also be viewed on page “Error Log”.
Once the sensing area is free again, the light curtain will be ready to detect further objects after about three
seconds.
While you cover the sensing area with the object, the status LED will light blue. In addition, in section “Chan-
nel Status” of the status page, entry “Covered” for channel 1 and possibly even further channels is set to
“YES”.
In addition, the counter readings are also displayed, and e.g. how long the object detected by the channel
covered the sensing area.
In the section “General Status Information” you will find information on the status of the device as well as
status images of all available digital input and output signals. Entry “State”, which is set to “running” and
highlighted in green, indicates that the light curtain is ready to detect objects.
If you exceed the standard maximum permissible passing time of 1s as described above, the entry “Output 1
(Monitoring 2): State” will change from “ON” to “OFF” and be highlighted in red instead of green. When the
sensing area is free again, the light curtain changes back to the ready state with a delay of about three sec-
onds, and entry „Output 1 (Monitoring 2): State“ changes to „ON“ with a green background.
