SYSTEM OVERVIEW
The MEL-1 motor retraction system has been designed to work specifically with the NP-1
power supply. The MEL-1 and the NP-1 each contain a computer that is constantly monitoring
the status of the system. This communication is done using the RED and BLACK power wire
that runs in between the NP-1 power supply and the MEL-1 retraction mechanism
