Lynx distributor says Fuse Blown but not the case

Dear people,

I have had a strange situation: Cerbo gives an alarm “Fuse B2” blown on the Lynx. This is the output to the Quattro so for the 230V-circuit/inverter. When I went to open the Lynx, I saw a 230V-appliance blinking so 230V was there (again). While opening the Lynx (on which a red light showed the defect fuse), the red light went off, the alarm on the Cerbo stopped and everything is normal again.

I checked for loose connections but everything is ok. What I know is that the inverter has stopped for a short time because a dishwasher was running and the program had stopped.

Anybody got an idea of what is wrong? How can a message “fuse blown” appear while the fuse is ok?

Kind regards,

Pim

What is the serial number or year of manufacture of the Lynx?

Hello,

It’s a new installation so I think 2024 but it can be old stock of course… I can’t find the serial in the software can I?

Maybe on the vrm? Under device list.
I was wondering as a recall from the old forum a series that would do this.

Unfortunately not, only the Lynx BMS is in VRM, not the distributors

Similar issue happened yesterday. We have been on the boat for 1 month, and yesterday on a long run, I received this error: “Battery Monitor - Lynx Smart BMS HQ2443G94VC [0], Distributor A Fuse 2 Blown: Alarm”. 2 minutes later, it cleared. It did this 8 times, with varying lengths of time before it resolved.

I did not lose power while the alarm was active.

I’m on firmware 3.55.
