This system uses an interlock module, an ignition switch
and three safety switches. The interlock module is
connected to the engine magneto and to ground. When
at rest, the module closes the connection between the
magneto and ground. The ignition cannot fi re.
When in the off position the ignition switch also grounds
the magneto. To start, turn the ignition switch to on,
which will open the contacts. When the recoil is pulled
a small amount of the current from the magneto is
taken by the interlock module and sent out to the switch
circuit. This current must go through the blade switch
and neutral switch and return to the module. This current
then activates the module and it will open the magneto
ground.
Once started, the operator will engage either the blade,
transmission or both. When either is engaged the blade/
transmission circuit opens. To prevent the module from
stopping the engine, the operator must be holding the
operator presence levers on the handles. This closes the
operator presence switch and maintains that signal to
the module.
