Practical AGV application (example)
The following example shows the sequence of zone pair changeovers for an efficiently
implemented AGV under consideration of the ambient conditions. Please observe the
particular danger zone analysis for each detection zone in combination with the
corresponding route segments. Also note the safe sequences of changeovers and starts.
For information on programming the startup detection zones (detection zones enabled for
starting up the scanner) and on determining the sequence in which the detection zones
are to be activated, please see the instruction manual (software operation) for the
SD3SOFT
.
FP = 1 × detection zone + 1 × warning zone
Practical AGV application
If the AGV is controlled by a PLC, for instance, which corresponds to Category 3 or
higher according to DIN EN 954-1, the previous zone pair (ZP) can be deactivated
immediately after the next zone pair has been activated, with no time delay.
This results in a faster switching sequence.
The applicable safety guidelines and standards as well as the operating instructions for
the systems must be strictly complied with.
