Keyswitch
Output function
You can configure the keyswitch function with the smart connect software. Go to Digital Outputs and configure one of the
outputs as Keyswitch.
Wiring
Wire the keyswitch relay output to the ECU power. When the relay is open, the ECU has no power.
How it works
For the first 5 seconds after the SGC controller is powered on, the keyswitch relay is open.
How the keyswitch functions works:
1. There is an engine stop command.
2. The Cooling down timer starts.
3. When the cooling down timer expires, the SGC starts the Extended stop timer, and opens the keyswitch relay.
4. The relay is open until the extended stop timer expires.
