The functionality of the Cyrix-Li-ct is analogous to the Cyrix-ct. The Cyrix-Li-ct will parallel connect a lead acid starter battery and a LiFePO4 battery:
– if the Charge Disconnect output of the VE.Bus BMS is high, and
– if it senses 13,4V (resp. 26,8V) or more on one of its power terminals.
The Cyrix will disengage immediately:
– when its control output becomes free floating, signalling cell over voltage or cell over temperature, and/or
– when battery voltage drops below 13,2V.
Start assist function: a short positive pulse will close the relay during 30 seconds.
