Check for compressor motor converter time out

Hi all,

* Check communication cable
* Isolate converter from module, and use the VSD simulation software to test whether module or converter is at fault.

–> A PC and RS485 <-> RS232 converter box is required as well as the DFM4win cable) is required.The cable is to be connected in place of converter cable connection. If the RS485 port is faulty ==> new module is required.
– Replace modbus adapter card
