(The output signals may be used in either the sink or source logic independently of the jumper connector position.)
NOTE
• Make sure that the jumper connector is installed correctly.
• Never change the control logic while power is ON.
 Sink logic and source logic
• In the sink logic, a signal turns ON when a current exits from the corresponding signal input terminal.
Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.
• In the source logic, a signal turns ON when a current enters into the corresponding signal input terminal.
Terminal PC is common to the contact input signals. Terminal SE is common to the open collector output signals.
