Configurable functions
4Configurable functions
Plan and carry out configuration carefully!
Incorrect configuration can lead to ineffectiveness of the safety function!
The configuration of safety applications must be carried out with the greatest accuracy
and must match the status and the condition of the machine or system to be monitored.
Check whether the configured safety application monitors the machine or system as
planned and whether the safety of a configured application is ensured at all times. This
must be ensured in each operating mode/program and partial application. Document
the result of this check.
Each safety application must be checked at a specific interval. The interval is to be
defined to suit the specific case dependant on the application.
In each case, observe the instructions for commissioning and daily checking in the
operating instructions of the protective devices integrated into the safety application!
Note the warnings and function descriptions of protective devices connected to the
safety controller! Contact the respective manufacturer of the protective device if in
doubt!
Functions such as the restart interlock, PSDI etc. can be configured in both the
UE440/470 and in a device connected via EFI. The UE440/470 does not check whether
or not these functions were configured with the connected devices. You must therefore
check whether the configured safety application monitors the machine or system as
planned.
The configurable functions of the UE440/470 are described in the following sections.
Examples for typical safety applications are found in Chapter 7 "Application and switching
examples" from Page 67 and on the Internet at www.sick.com.
4.1 Base settings with the configuration wizard
The functions which you can configure using the configuration wizard are described in this
section.

Configurable functions
4.1.2 Programs and program selector switch
You can configure up to five programs for your safety application(s) with the UE440/470.
In each program, 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 programs of the machine or
system to be secured.
You can save a name for each program during configuration in the CDS. Use this function
as a reminder, e.g. to describe the program.
Check the protective device in every program and after every change to a program!
If you configure several programs, you must check the operation of the protective device in
each of these programs. Please observe the test notes in the operating instructions of the
connected protective device.
Up to two safety applications can be adapted and configured to the requirements of the
respective program.
Input and output elements are configured once for this and remain the same in each
program.
Logic module, release module and function module can be configured individually for
each program.
Connections between input and output elements and between the logic module, release
module and function module can be configured individually for each program.
A configured input element should generally be used in all programs 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 programs, 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 programs, 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 programs that are in use.
If the program is changed with activated bypass (e.g. with a changeover from program 1
to program 3) (see Section 4.2.11 "Bypass" on Page 35), bypass is deactivated and the
UE440/470 switches to the new program.
If the program is switched while teach-in via a Teach-in key-activated switch connected
to the UE440/470 is active, the UE440/470 first remains in the previous program (see
Section 4.6 “Teach-in for C4000" on Page 49). Only after the teach-in is complete does
the UE440/470 switch to the selected program and forward the information on the new
program, e.g. to the C4000 Standard/Advanced, if such forwarding is configured via EFI
in the CDS.
This applies only if the program change is configured simultaneously at the UE440/470
and at a protective device connected to EFI (for example S3000 or C4000).

Configurable functions
Do not start teaching-in until all the delay times and filter times have expired!
If the operating mode is switched and the teach-in process activated while the time delay
at Out2 is running, the teach-in process is carried out in the old operating mode at the
C4000.
Observe the filter times in the connected EFI devices and the set filter time for the
operating mode for the operating mode switch-over in the UE440.
Program change for devices connected via EFI
The status of the program selector switch of the UE440/470 can be transferred to a
protective device connected via EFI.
The program selector switch can be configured in such a way that the program change of
the EFI device…
occurs at the same time as the program change of the UE440/470.
occurs independently of the program change of the UE440/470.
With a simultaneous program change, the status of the program selector switch of the
UE440/470 is transferred to an EFI device. In this case, both the UE440/470 and the
connected protective device switch to another program when switching occurs.
In the case of an independent program change the status of local inputs is transferred to
an EFI device.
The behaviour of the safety controller during a program change can be configured
according to the "Program change" setting (see Section 4.1.3 "Program change via the
program selector switch" on Page 20).
When transferring the status of a program selector switch to a device connected via EFI,
the same number of programs/operating modes must be configured there. Ensure that
when a C4000 is connected, the same number of programs/operating modes are
configured in both it and the UE440/470.
If the status of the program selector switch is transferred via EFI to a safety laser
scanner S3000, then there is a switching between the monitoring cases. The OSSD of
the S3000 can remain switched on during this switch, depending on the protective field
status. The behaviour of the outputs of the safety controller is in accordance with the
"Program change" setting (see Section 4.1.3 "Program change via the program selector
switch" on Page 20).
Observe the notes on program, operating mode and monitoring switching in the
operating instructions of the connected EFI devices (e.g. Changeover time with S3000).
Program switching of the UE440/470 with program selector switch
The operator can switch between the programs by means of a program selector switch.
The behaviour of the outputs of the safety controller is in accordance with the "Program
change" setting (see Section 4.1.3 "Program change via the program selector switch" on
Page 20).
After switching, the condition of the outputs depends on the configured application and
the input signals at their inputs.
As soon as you configure several programs/operating modes in the CDS, the program
selector switch automatically appears in the pin assignment of the safety application. It
has as many inputs as configured programs/operating modes.
The program selector switch must be a (1-of-n) key-operated switch.

4.1.3 Program change via the program selector switch
You can configure the type of program change in the configuration wizard.
The following settings are possible:
Program switching
Operating mode switching
If you configure the program change as a switching of the operating mode, secure
deactivation of the outputs assigned to an application occurs during the changeover time.
If you configure the program change as a switching of the program, secure deactivation is
not in effect. Here, the status of the outputs is retained during the changeover time.
The setting ...
can be executed separately for application A and application B
applies for all configured programs
applies for the release, logic and function module in each application
does not apply for input elements routed directly to outputs (outputs are deactivated for
10 – 20 ms for each program change).
Activation of the program change depends on the filter time, changeover time and the
delay time of the outputs.
Program switching: Secure deactivation not in effect with program change
During the changeover, the assigned outputs retain the status they had right before the
changeover: one active output remains active, one passive output remains passive.
In the new program …
the input conditions are checked again
a configured internal restart interlock is not taken into account if the input conditions are
fulfilled after switching of the program (exception: In the new program, an application is
implemented with one PSDI function module or one function block with machine cycle
contact evaluation.)
a bypass already activated in an old program or an activated two-handed input device is
not active
the application switches directly to the active state with correct input information if the
restart interlock is configured externally in the new program. (exception: In the new
program, an application is implemented with one PSDI function module.)
If the delay time at Out2 has already expired with the valid detection of a new program, a
program change occurs after the delay time has expired (for setting the shutdown delay
of the Out2 output, see Section 4.2.12 on Page 37).
