Hello
I have just checked 4 units of above model and find ;- Pro Dialog 5, CSA-SR-20C 470301 software according to screen.
a) 1 system has a burnt out compressor, (only started last year sometime, no commissioning sheets)
b) 3 units have software faults, initial 1 locks out units as fault is thermal protection in starters is open. Contacts actually closed but open fault remains.
c) disconnecting flow interlock should give an open signal however this does not happen and appears chiller can run with no flow,
Question, have heard rumours of this before I have actually found (flow interlock fault) causing freeze ups. Can anyone advise on software problems and ways to go.
Has anyone got software, units about 2 years old and out of warranty.
Can get more info as required because im very green on these units.
Regards for now
