Power supply RTI-control module
If the RTI control module power supply (30-supply) fails in some way, the control module is disconnected, the battery disconnected etc, certain data in the control module will be erased after a certain period of time. This means that the control module then assumes certain predetermined values the next time the system is activated. When the control module is reconnected certain values should be reset.
