Victron Energy Cyrix-Li-Charge Intelligent Charge Relay - 12/24V

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
• It senses 13V (resp. 26V or 52V) or more on its battery charger connection terminal
• 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 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.

When the Cyrix-Li-Charge is engaged (charger connected to battery) it will disengage after 1 hour to check if the charger is still enabled. If, after the Cyrix has disengaged, the output of the battery charger immediately increases to 13V or more, the Cyrix will reengage, with a 3 seconds delay.

Note: 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 13V.
