Hi Pete - I'm sure that the PC is not instructing the UPS to power down, as at the point that the hissy fit occurs, the PC is fully down, not running and has no power! However I suspect that as the UPS is programmed to reboot as soon as power is returned, this feature is actually happening 2 minutes after power is back on - perhaps APC's interpretation of immediate varies from mine ! My requirement is to shut the PCs down gracefully rather than to keep them running through a power cut, so I think that it is probably best to leave the config as it is, and work round the issue by not bringing the PCs back on line for several minutes after power is restored, which is no great hardship. |

At least you have a PC still running Monday we had a power cut , and the PC wouldnt start after the power came back on , power supply fried also took out the hard drive and floppy , only half my data backed up :doh: but now I have a one tereabit drive I have no way of backing that up iff it's full , agro I could have done without . |

Well at long last I have been able to source a generator that meets my specification in price and 'solidness' ! It's based on a 3 cylinder Lister ST03 diesel engine driving an alternator rated at 12.5 kVA as a base load. Many of the modern import generators are useless for long running, and although this hopefully will only ever occasionally run for a day or so it should do it reliably. It has been a stand by set in Council offices and probably has only run for regular test runs, showing 100 hours on the meter. Our absolute top load limited by the 100 amp company fuses is 25 kW so 12.5 will amply cover virtually anything running, including our 'cottage guests' using their hobs, ovens, kettles etc !!! |

I think that the engine dates from the mid to late 1980's - it may or may not have been new when Puma incorporated into a generating set - it's obviously been re-painted looking at the engine plate. Not physically seen it yet - just been arranging for it's collection by a pallet company. The good thing is that it comes with a brand new auto change-over starter panel |

It's fairly doubtful that I'll have it installed and up and running this winter. I need to construct some sort of weatherproof housing for it close enough to our main power connection, and also fabricate a fuel tank. The design of the housing is a bit limited as it will be in a pretty visible place. I suppose that I could locate the main change over relay close to the company meter in a wall housing, and drive it remotely, so I could tuck the generator out of sight. That at least reduces the run of heavy duty cable (25 or maybe 35 mm csa) to one pair as it is stupidly expensive :bugeye: |
