1.2.1. Manual reset mode / Auto reset mode
The manual reset mode activates the interlock function, and the auto reset mode inactivates
it. 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.
