Logic input switch (SW1)
The logic input switch (SW1) is used to adapt the operation of the logic inputs to the technology of the programmable controller outputs.
• Set the switch to Source (factory setting) if using PLC outputs with PNP transistors.
• Set the switch to Sink Int or Sink Ext if using PLC outputs with NPN transistors.
• Switch SW1 set to “Source” position • Switch SW1 set to “Source” position and use of an external power
supply for the LIs
• Switch SW1 set to “Sink Int” position • Switch SW1 set to “Sink Ext” position
WARNING
UNINTENDED EQUIPMENT OPERATION
When switch SW1 is set to “Sink Int” or “Sink Ext”, the common must never be connected to ground or the protective ground,
as there is then a risk of unintended equipment operation on the first insulation fault.
Failure to follow this instruction can result in death, serious injury or equipment damage.
