Hello,
I need a little help with the Settings or wiring in the system of my Truck.
My System have:
4x 200Ah Victron Smart Batteries in 24V
Lynx Distributor for Batteries IN
Lynx Smart BMS
Lynx Distributor for Inverter OUT
Lynx Distributor for Charger IN and several Loads OUT
Skylla i charger 24/80
Cerbo GX & Touch 70
VE.Can from Skylla to Lynx BMS. (Terminal at the end)
VE.Can from Lynx Smart BMS to Cerbo GX. (Terminal at the end)
All Batteries M8 cables are connected to each other and final to the Lynx Smart BMS
Power IN for the Cerbo GX comes from the Lynx BMS (PIN 1 and 2)
PIN 10 and 11 are connected.
ATC/ATD and Relay are open. (no cable)
On the Touch 70 i can see the Skylla and the Lynx Smart BMS. (means VE.CAN connection should be okay)
Where do I need help now?
I tried to test my installation on a cold winterday with battery temperature lower than 3° C.
(Battery charge setting are at 5°C)
When I switch on the Skylla Charger, the Lynx Smart BMS disconnects the Batteries a few seconds later.
I get an Alarm #36 ATC/ATD Fail.
It means:
Your system doesn't react to reduce or diconnect the load.
(Please check Can Bus / ATC/ATD wiring)
Okay. One part I understand.
The Lynx Smart BMS works and protects the Batteries from a charging.
Great!
But why did Skylla try to start charging a low temperature Battery Bank?
As a result, the contactor in the Lynx BMS cut off the whole system.
I thought the Skylla i, the Lynx Smart BMS and Cerbo GX “talk” to each other.
Can somebody tell me which settings or wiring i need, that the Skylla i control the charging in a proper way?
Best regards Robert
