Compressor doesnt unload in sequenced mode
Good Day,
We have 3 sabroe 163 mk4 compressors with 2 currently online.Im trying to run them in sequenced mode instead of auto mode but in sequenced mode the compressors will not unload causing the suction to go up to 10"-12" hg,The suction pressure is set at 4.0" hg.When we run them in auto mode they load and unload correctly.Anyone have any ideas ,these are the sequencer setpoints.Set points.jpg

Re: Compressor doesnt unload in sequenced mode
What type of controller do you have is it a UNISAB? I know from bitter experience that on the UNISABs you need to have all the set points, differentials, deb band etc exactly the same on all the machines. And when I say exactly I mean exactly.
