Configurable functions
$ As an option you can connect a switch for deactivating blanking to the C 4000 Advanced
(see section 6.6 “Teach-in key-operated switch” on page 52).
$ You have already configured the number and type of blanked areas as well as the tole-
rances with the aid of the CDS.
$ You have activated the option Teach-in key-operated switch active in the CDS:
Device symbol C 4000 Host (receiver), context menu Configuration draft, Edit, file card
General, option Teach-in key-operated switch active.
Limits for teach-in operation
$ You can only activate the teach-in function for the entire system. It is not possible to limit
the teach-in to specific sub-systems (host, guest), specific areas, or specific operating
modes.
Prevent teach-in in areas or operating modes where it is not intended to be used!
A successfully completed teach-in process changes the size and, for fixed blanking, also
the position of the blanked areas. Areas of unsuitable size or in an unsuitable position
can reduce the availability of the system. For this reason:
Ensure by means of organisational measures that the operator only teaches in those
areas and only in those operating modes that are also suitable in relation to the appli-
cation.
Ensure that only authorised persons have access to the teach-in key.
$ You cannot add or delete any blanked areas using teach-in. Use the CDS to define the
number of blanked areas.
$ If you use a SICK switching amplifier (e.g. UE 402) in conjunction with an operating mode
selector switch, then the change in the operating mode is effective when the teach-in
key-operated switch has been set to the “Operation” position again. The taught-in areas
always apply for the operating mode that was set when the teach-in key-operated switch
was switched on.
$ The mounting position can change slightly on a device change. For this reason it is re-
commended in this case to teach-in the areas again.
This is how you teach-in a blanked area:
Set the teach-in key-operated switch to the “Teach-in” position.
The safety light curtain changes to red.
Guide the object or objects into the protective field.
You must guide an object of suitable size into the protective field for all blanked areas.
There must be no other objects in the protective field.
Press the reset button for at least 0.2 seconds.
After the button is released, the C 4000 Advanced saves the interrupted part of the pro-
tective field as a blanked area. The 7-segment display on the receiver indicates ? if the
objects represent valid areas to be blanked.
If the number or arrangement of the objects does not match the configured areas for the
individual system, or the necessary minimum distance is not met, then the old areas for
the system remain valid. In this case the 7-segment display on the receiver indicates (.
You can correct the arrangement and repeat the step.
