INTERLOCKING
The interlock input (pin 3) must be active before the Twister will
allow control of the engine’s RPM.
It is the OEM’s responsibility to create a safe interlocking scheme to
activate the Twister’s interlock input.
The Twister’s green THROTTLE READY LED will ON when the
interlock input is active. The Twister
is now ready for operator
initiated control.
