  • Page 3: Functions

    This function stops light emission of an emitter. It is available for checking if the F3SN can show the correct OSSD (Output Signal Switching Device) outputs state, and so on. [Directions for use] Applying a voltage of 24VDC (for PNP type) or 0 V (for NPN type) to the test input line of an emitter makes the emitter stop emitting.
  • Page 4: Interlock Function

    These modes are wire selectable features of the F3SN. When the F3SN is set as “Start interlock valid” and/or “Restart interlock valid” and the wir- ing corresponds to “Manual reset mode”, the interlock function(s) are available. For the fac- tory setting, both the start interlock and the restart interlock are set valid.
