Configurable functions
$ With reduced resolution, the 7-segment display indicates ? as soon as sender and re-
ceiver are aligned.
Check the safety distance!
The safety distance required under reduced resolution depends on the effective resolution.
 If required, recalculate the safety distance and readjust it on the machine.
Example: – physical resolution 14 mm
– resolution reduced by 1 beam
– effective resolution 22 mm
Calculate the safety distance with a resolution of 22 mm. (See page 37.)
 Mark the effective resolution on the information label “Operation with reduced resolution
or blanking …” on the related sender and receiver.

Warning: During operation with “Reduced resolution” or “Blanking” the safety distance
that corresponds to the modified resolution is to be observed.

effective resolution in millimetres directly.
4.10 Sender test
The C 4000 sender has a test input on pin 3 for checking the sender and the related re-
ceiver. During the test, the sender no longer emits light beams. Thus, it simulates — for the
receiver — an interruption of the protective field.
$ During the test the sender indicates =.
$ The test is successful, if the C 4000 receiver switches to red, i.e. the output signal
switching devices (OSSDs) are deactivated. In a cascade this only applies for the host.
C 4000-Sender and receiver are self-testing and do not require any external sender test.
You can deactivate the sender test with the aid of the CDS, if the test is not required for
the current application.
To be able to perform a sender test …
$ the option Enable sender test must be active. This is the condition as supplied.
$ a means of controlling the test input must be available.
Device symbol C 4000 Host (sender), context menu Configuration draft, Edit, option
Enable sender test.
If you do not connect the test input, then you must deactivate the Sender test function
with the aid of the CDS. Otherwise the light curtain will be permanently switched to red.
The electrical connection at the test input is described in chapter 6.10 “Test input (sender
test)” on page 55.
