Hi guys

Did look through here for an answer but was nothing definitive.

Am at a call out for the above chiller which has gone into fault on circuit 1, current/MP/HPX and C2 has gone out on low suction.

Have checked fridge pressures and all seem ok, overload led on opto board is illuminated, starting current of comp is 141amps, according to the system display oil pressure is ok too.

Being it’s hot and I’m in London atm with temps of say 30 would the oil be an issue? The comps are old and have a few leaks, top end a bit rattly also.

So scratching my head really. C1 starts up, goes delta then star and literally 2 seconds later goes into fault and ar timer starts.

Anyone had any joy or similar issues with these?

Thanks in advance
