Switch for logic input (SW3)
The logic input switch (SW3) is used to adapt the operation of the logic inputs to the technology of the programmable
controller outputs.
•
When using PLC outputs with PNP transistors switch to the right-hand position (Sink).
•
When using PLC outputs with NPN transistors switch to the left-hand position (Source Int.) or the middle
position (Source Ext.)
Important!
Only switch on the SW3 when the power supply is switched off.

Warning!
ACCIDENTAL OPERATION OF DEVICE
If switch SW3 is in position "Source int." or "Source ext.", then the reference conductor is never per-
mitted to be connected to ground or protective ground; otherwise, there is the risk of unintended de-
vice operation when the first insulation fault occurs.
Failure to follow this instruction can result in death, serious injury or material damages.
