I'm Rami from Palestine, we are working in a new DC, and installed two Units of ACRP102 InRow RP DX for this DC, when I try to start up the unit for the first time, the unit gave me one alarm and one warning.
Really I can't solve this problem, what are you advise to do?
Hello Rami. If you can look under the compressor status on the front screen there is a section that shows and alarm code for the compressor drive. If you can get this an call into your local tech support, they will be able to decode it and give you steps on what needs to be done. So common things that you can check in the mean time is to make sure there are no loose wires or connections (will need to be done by an HVAC tech) and make sure the oil sight glass is half to 3/4 full.
I did that before by myself, but I'm still wait Schneider response.
here my last E-mail to them
Because of the problem occurred by the VFD (Compressor drive), I have checked the history alarms of the VFD, the alarms were:
Backing to Danfuss Operating Instructions VLT® CDS 302 and CDS 303, these alarms related to Motor output phases loss
Alarm 30, 31, and 32.
But I checked the cables which are between the Compressor and the VFD, all of them are OK, and I have checked the Resistance between the Compressor terminals, they were about 1 ohm. Also I checked the starting current of every phase when the VFD trying to run the compressor; the currents were: 16A, 19A and 21A.
Now please confirm If I can do these test:
Hello. You can swap the VFD's and see if the issue follows the VFD. I would NOT recommend hooking the compressor directly to power. Check the lines to ground at the compressor lugs to make sure the compressor is not grounded.
Thank you very much
I have changed the VFD and the Compressors
yo tuve el mismo problema
y se soluciono solo cambiando el compresor ya que la logistica fue la culpable de la falla
al abrir el compresor para saber realmente cual era la falla nos dimos cuenta que la alta presion que deberia ir hacia el condensador este botaba todo hacia el mismo compresor dando la alarma de alta presion.
