Lynx BMS 500 24v Pre charge time out and ATC/ATD failure error explanation

Hello Victron Community,

I am having issues with my Lynx smart BMS 500 24v. I am getting what seems like random pre charge time out errors and ATC/ATD failure. Could someone explain the function of the pre charge circuit after the system has been powered up and running for weeks?

The system includes;

Victron VE LFP 25/200 ah (2)
lynx input
lynx smart BMS 500
lynx distributor powering tender lift, davit, bow thruster.

Mppt 48/24 used for charging the system with the 24v input connected to the lynx distributor. That doesn’t appear to be networked

When examining the vrm details the system is always at a high voltage and SOC at the time of fault. I believe the ATD\ATC failure is being caused by the charging source mppt that isnt controlled by the BMS. But the Pre charge error has me confused.

Many Thanks.
