External switch and starter disable/enable circuit
Utilizing features 1 and 2 above permits establishing an auto start/stop system that can be operated through
an external sequence. See

given from an external control device in place of the key switch.

Connection diagram of an auto start/stop system
The engine run signal goes on at engine start and goes off at engine stop. If it is not detected that the engine
has started, the start signal must be turned off within 160 seconds as a guideline. Otherwise, the starter tries
to start the engine repeatedly in intervals of 30 seconds.
