The reset button is located behind the blanking plate of the NCU.
A reset operation resets the entire system and requires a system restart. This is comparable
to a "Power On reset" except that the 24 V power supply does not have to be switched off.
Booting for servicing purposes
For service or diagnosis purposes, the NCU can be booted from a service system, the
Emergency Boot System.
