48V Bidirectional Motor Generator (BMG) Operating Manual

4.1 Wake Up ................................................................................................................................. 14 4.2 Power On ................................................................................................................................ 14 4.3 Idle Mode ................................................................................................................................ 14 4.4 Generator Mode ........................................................................................................................ 15 4.5 Error ...................................................................................................................................... 15 4.6 Warm-up Mode ......................................................................................................................... 15 4.7 Power Down ............................................................................................................................. 15 4.8 Shut Down ............................................................................................................................... 15 5 Scotty AI ....................................................................................................... 16 Scotty AI is recognized in the Victron Device List. ..................................................... 16 However, if using Victron Lithium batteries the Charge Current Limit and Discharge current limit are not read as these parameters are not support by NMEA. .................................. 16 So still connect Scotty AI and BMG to the VE.CAN but set the battery as a non-CAN battery. 16 There will be NO DIFFERENCE to the charging rate as we have te algorithms for speed of charging set exactly the same whether on CAN or Not. ............................................... 16 Then Set the Battery Charging Parameters of Bulk, absorption time and Float voltages for the 48V Charging. Even if the batteries are on CAN always set these values as they are a fall back when self healing if there is a CAN error on the network. ............................................. 16 With Scotty AI connected to the 12V or 24V Alternator (Highly recommended), you still need to perform the AI driven “Auto-tuning”. (See Scotty AI Manual for that) .......................... 16 Then Once Auto-tuning is complete, go to next step on following page: ......................... 16 BMG “Setup” Mode on Scotty AI Tuning Page ......................................................... 17
