Adamw Posted November 23, 2021 Report Share Posted November 23, 2021 Can you do a short log of the engine running and you switching the AC on/off a couple of times. Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 25, 2021 Report Share Posted November 25, 2021 The AC is being locked out due to "low pressure". But, testing on the bench I think the problem is due to an error in our predefined pressure sensor calibration. I have passed that on to the firmware team to take a look. In the meantime you can set it up with a user cal like below should fix it. Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 25, 2021 Report Share Posted November 25, 2021 Actually, Vaughan has just fixed the calibration in the firmware. I will send you a PM with a new PC Link and firmware you can load and try. Quote Link to comment Share on other sites More sharing options...

Timboj Posted January 21, 2022 Report Share Posted January 21, 2022 Did that work for you? I'm getting the same low pressure lockout on the latest firmware. Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 21, 2022 Report Share Posted January 21, 2022 The AC press fix is in a later firmware version than is on the website. I have attached a copy below. download the .img file then use the "browse" button in the firmware update tool to browse to the downloaded firmware.
