First make sure you are using the latest firmware(4.1.27). If you are not you may be using the older Ion Studio software. It has been replaced with Basicmicro Motion Studio. Unfortunately when the name changed it was not possible to have Ion Studio automatically udpate to Basicmicro Motion Studio.

Next reset the controller to defaults and then setup your controller again. The Logic Battery error can be cause by a bad configuration in non-volatile memory.

If you are still getting a logic battery low error, froun the LB+ pin and test if the error goes away. If it does not then it is a false logic battery error becaused by some other problem. Other warnings/errors may be showing in that case. If so what are they?

Yes, depending on how old the unit is, if the main battery is higher than the logic battery minimum then the logic battery voltage is ignored. Old units do not do this though(ones with the LB-MB hardware jumper).
