The Sapphire v3 can interrupt a connection in the
machine to prevent an operator from driving.
Which connection to interrupt depends on the
machine type. This will be different between
electrical vehicles and combustion engines.
In a vehicle with a combustion engine, the easiest
connection to interrupt is the starter relay coil.
An electrical vehicle usually prevents an operator from
driving when one of the following connections is
interrupted: driver seat switch, driver seat belt
switch, charging switch/input, …
Make sure you never circumvent any of the safety
features of your machine; always consult your vehicle’s
technical manual.
The Sapphire v3 will use active blocking, so make sure
to use the normally closed contact of the relay.
Only use a 12V relay with
built-in flyback diode - as
included by default in the kit.
