4.8.4 Teach-in of blanked areas
Teach-in enables the operator to re-define the size of blanked areas in a simple manner by
introducing an object of appropriate size into the protective field at the required position.
This is, e.g., useful during a tool change.
Requirements
To be able to use the teach-in function, the application must meet the following require-
ments:
A reset button is connected to the C4000 Advanced and is correctly configured (see
chapter 6.7 “Reset button” on page 58).
A teach-in key-operated switch or a comparable tamper-proof device, e.g. an MMI with
password protection is connected to the C4000 Advanced (see section 6.8 “Teach-in
key-operated switch” on page 59).
As an option you can connect a switch for deactivating blanking to the C4000 Advanced
(see section 6.8 “Teach-in key-operated switch” on page 59).
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 C4000 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.
TeachCin is not available in connection with C4000 Guest devices with M12 system
connection (type code C46).
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
application.
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. UE402) 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.
