Cyrix-Li-Intelligent Charge Relay 12/24V-120A Victron
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 13,7V (resp. 27,4V or 54,8V) or more on its battery charger connection terminal, and
- if it senses 2V 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 output 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 two attempts to re-engage with 3 seconds delay, the delay increases to 10 minutes.
Whenever battery voltage is less than 13,5V (resp. 27V or 54V), the Cyrix will disengage with a delay of 1 hour.
Note 1: In case of zero discharge current, or a small discharge current, the Cyrix will not disengage shortly after the charger has been switched off and/or disconnected, because battery voltage will remain higher than 13,5V.
Note 2: If, after the Cyrix has disengaged, the output of the battery charger immediately increases to 13,7V or more, the Cyrix will reengage, with 3 seconds delay.
