12 INCREASE OF THE NUMBER AND THE LOADING CAPACITY OF THE CONTACTS
If necessary it is possible to increase the number and the loading capacity of the
output contacts by using external contactors with forced guided contacts.
Feedback circuit for external contactors
with automatic start wiring
Feedback circuit for external contactors
with manual or monitored start wiring
For a correct system operation any safety module or PLC connected to the electronic safety outputs
OSx have to tolerate the pulse tests that are made on safety outputs .
13 DISPOSAL
At the end of service life product must be disposed of properly.
