Victron Cyrix-Li-Charge 24 / 48V 230A Intelligent Charge Relay

The Cyrix-Li-Charge will connect a battery charger with 3 seconds delay:

• if the charge disconnect output of the VE.Bus BMS is high, and
• if it senses 13.7 V (resp. 27.4 V or 54.8 V) or more on its battery charger connection terminal, and
• if it senses 2 V or more on its battery terminal (the Cyrix will remain open if not connect to the battery).

The Cyrix-Li-Charge will disengage immediately whenever its control input becomes free floating, signalling cell over voltage or cell over temperature.

In general a cell over voltage alarm will reset shortly after charging has been stopped. The Cyrix will then reconnect the charger after a delay 3 seconds. After 2 attempts to reengage with 3 seconds delay, the delay increases to 10 minutes. Whenever battery voltage is less than 13.5 V (resp. 27 V or 54 V), the Cyrix will disengage with a delay of 1 hour.
