I've never come across that fault and can't find any reference to it.
Maybe call their technical number?

Hi Mikas.
A stupid question maybe!
But have you checked the Incoming supplies and contactors?
Worth a try.

Hi Mikas
This sounds like it is the electronic motor protection unit fault for the compressor. The motor protection module can be reset by removing the power feed to it for 25s. It stores fault counts then locks out till reset.
If it does not reset or resets then faults again you either have motor motor thermo protection fault or faultly compressor motor.
You are unable to reset this from controller.
