Starting Input

The starting (cranking KL50) input is monitored by the IHKA to "unload" consumers during engine cranking. This is a momentary signal that will cause the IHKA to deactivate heavy power consumers.

This signal has a dedicated circuit on E31/36 models, and is transmitted via BUS communication on all other models.
