A-AC/A-SPI indicates a phase loss in Hybrid power supply mode, probably due to no utility input received in this mode. This means P15.32=0, indicating the AC input is disconnected. Simply connect the AC input or change the mode back to Mode 0.

 FAF means Forced Communication Failure, probably not receiving AC input in AC mode, VFD wants to switch to AC input, but no AC input, also caused by the mode change. this is an early warning, not a fault. It means that you are using Hybrid power supply mode, but there is no AC input. You only need to connect the AC input, or change the mode back to mode 0.

Firstly must make sure the APN info is the suitable with SIM card, then check with the network supplier, if the GPRS installation location support GPRS network, without GPRS network, it cannot connect to internet.

If network online, means the GPRS adaptor APN information is correct. RS485 off-line means the tac file is incorrect, please contact INVT to update tac configuration file.
