Important information
WARNING
If the safety-related application software is expanded and used for other safety func‐
tions, the additional function blocks must be strictly separated, on separate logic
pages, from the Safe Entry Exit function blocks.
The logic pages for Safe Entry Exit may only be changed as described in this document.
Any other changes can impair the safety of the system.
NOTE
Configured time values are subject to a tolerance during evaluation. This depends on
the function blocks used and CPU cycle time, among other things.
For detailed information on the time evaluation in Flexi Soft logic, see the Flexi Soft
operating instructions in the Flexi Soft Designer software (part number 8012998).
Adjust configuration
The configuration must be adjusted on the following logic pages:
•
Sequence monitoring
•
Time monitoring
•
PLC monitoring & override
All user-defined function blocks in the safety-related application software are locked
and do not have to be configured.
Data relating to the speed of the conveyor and the size of the material being trans‐
ported are needed for the settings of the
Timer
and
Event counter
function blocks.
Complementary information
An Excel tool is included in the download archive, together with the project file. This
Excel tool can help with calculating the settings for the function blocks.

Configuration of
Sequence monitoring
“Initiation” network
Figure 4: “Initiation” network
This network contains an
Adjustable off-delay timer
function block. Up to four different
times can be configured for different conveyor speeds, depending on the application.
These times can be selected using the optional Timing Set Selection,
. If this function is not used, only the
Off delay time 1
parameter
needs to be configured.
