Configurable functions
4.1.2
Operating modes and operating mode selector switch
You can configure up to five operating modes for your safety application with the
UE 440/470. In each operating mode, you can configure different links between the
connected sensors and actuators and integrate the protective devices connected via EFI
into the application(s). This gives you the option of matching the application(s) to the
operating modes of the machine or system to be secured.
You can save a name for each operating mode during configuration in the CDS. Use this
function as a reminder, e.g. to describe the operating mode.
Check the protective device in every operating mode and after every change to an
operating mode!
If you configure several operating modes, you must especially check the operation of the
protective device in each of these operating modes. Please observe the test notes in the
operating instructions of the connected protective device.
Observe EN 963 when executing the BDC.
Up to two safety applications can be adapted and configured to the requirements of the
respective operating mode.
$
Input and output elements are configured once for this and remain the same in each
operating mode.
$
Logic module, release module and function module can be configured individually for
each operating mode.
$
Connections between input and output elements and between logic module, release
module and function module can be configured individually for each operating mode.
A configured input element should generally be used in all operating modes and
connected to other elements for this reason. The CDS checks whether this is the case
when saving the application. If the CDS determines that an input element is not used in all
operating modes, you are notified of this and must confirm this explicitly.
If you do not wish to use a configured input element in one or more operating modes,
check whether this is permissible with the application!
Ensure that all connected elements are integrated in the safety application. This is
especially important when it is an element critical for safety (e.g. an emergency stop or
ESPE)!
$
An electrical connection may only be made for operating modes that are in use.
$
If the operating mode is switched with activated bypass (e.g. when switching from
operating mode 1 to operating mode 3) (see Section 4.2.9 "Bypass" on Page 30), bypass
is deactivated and the UE 440/470 switches to the new operating mode. If the bypass is
to be reactivated, the key-operated switch for bypass must be actuated again.
$
If the operating mode is switched while teach-in via a Teach-in key-activated switch
connected to the UE 440/470 is active, the UE 440/470 first remains in the previous
operating mode (see Section 4.5 “Teach-in for C 4000" on Page 40). Only after the teach-
in is complete does the UE 440/470 switch to the selected operating mode and forward
the information on the new operating mode e.g. to the C 4000 Standard/Advanced, if
such forwarding is configured via EFI in the CDS.
This applies only if operating mode switching is configured simultaneously at the
UE 440/470 and at a protective device connected to EFI (for example S 3000 or
C 4000).
