7.1.8.2 SI4000 configuration for light barriers, light grids, light curtains etc.
The SI4000 also supports direct connection of contact-free protective eqipment with two
self-testing outputs such as light barriers, light grids, light curtains, laser scanner etc.
CAUTION!
Sensors with self-testing outputs
Only sensors with self-testing outputs and a maximum sensor self-test duration of
350 µs may be connected to the SI4000.
Parameter
To connect these sensors please set the following parameters for the SI4000 in
ProMaster:
m
Connect the two sensor signals either to channels 1 and 2 or channels 3 and 4 and
activate the two-channel evaluation for the two inputs used.
m
Set the SI4000 sensor test for the two inputs used to
