16-09-2012, 08:09 PM
after replacing the burned power supply by a new one and entering the new t/p code.
I have try to operate the sab 233 s nh3 compressor.
After the compressor runs manually (unisab 3)for 1 to 2 min at low rpm 1000 it give a strange sound and shutdown.
is there somebody who is familiar of the danfoss vlt 355 kw who can advise what to do?
