My ccgx is stuck in a reboot loop if powered up with the Tank 140 connected. Disconnecting just the Tank 140 will allow the ccgx to boot correctly. The Tank 140 works fine if reconnected after the ccgx has fully restarted.

Ccgx reboot loop with Tank 140
Hi, Start with checking the firmware version of your CCGX: update it to version v2.73, which is currently the latest version
if that doesn’t fix it: what else do you have connected to the USB ports?
and whats the power connection like to the GX device? Perhaps its a power issue?
Thanks!
BMV-712
MPPT 150/70
Multi-Plus 120/3000
The CCGX is running the latest 2.73
I do have 2 sets of two tanks connected to the Tank 140. One of the sets is using internal 24V from the Tank 140.
the CCGX is connected to the main battery bank (large LiFePO4 battery)
Any suggestions in addition?
Hi, make sure the power connection to the CCGX is ok; by double checking the wiring for loose contacts; and possubly measuring the voltage at the power in terminals of the CCGX.
And what happens when the GX tank is connected, while the tanks are not?
can you post a picture of the (power) wires to the CCGX.
above is all to make sure that its not a power-dip problem due to loose contact, or voltage drop or similar.
The combination of components you listed is ok; that won’t cause any issue.
Ps. Is the system on VRM? Then I can ask an engineer to login and check the logs
I found the problem! I used the internal 24V supply for two ultrasonic sensors. They happen to consume 44mA which is more than twice the allowed current. The 140 kept resetting its internal over current protection and drawing just enough of a load over the USB to cause the CCGX to fail on reboot - hence cycle about every 1-2 seconds.
I rewired the sensors to feed off the 12V system avoiding the internal overcurrent protection. Now it works fine. I just have to go back through and recalibrate.
Thank you!
