Nut upsuser - Oct 2005 - Fenton PowerPal 660 strange reading and issues...

Hi There, i have a strange problem with a fenton powerpal 660. When you 
switch off the power to the UPS (from the wall), the server (IBM xSeries 
203) attached to it dies...However, if you unplug the cable from the 
server to the UPS and plug it back in again (with the power still out to 
the UPS), the server starts up again (set to power up after a power 
failure) and runs with no issues. I have noticed a "Wiring Fault"
light
on the back when you do this...

There is also a strange reading from the battery..

dev:~# upsc powerpal@localhost
battery.charge: -143.2
battery.voltage: 13.3
driver.name: fentonups
driver.parameter.port: /dev/ttyS0
driver.version: 2.0.1
driver.version.internal: 1.22
input.frequency: 50.0
input.transfer.high: 284
input.transfer.low: 168
input.voltage: 233.0
output.voltage: 232.0
ups.load: 011
ups.mfr: Fenton
ups.model: PowerPal 660
ups.status: OL

Any help is well appreciated.

Sometimes the wiring fault indicator circuitry gets confused if the
UPS suddenly loses its ground connection. (If the power were to fail
due to a tripped circuit breaker, you would still have a connection to
ground.)

Another possibility is that you actually have a wiring fault, but it
is not detected until you pull the plug. If you have a multimeter, you
can check to make sure there is no AC voltage between neutral and
ground. If so, or if you don't like the idea of poking metal into a
live outlet (with 220V and a potential wiring fault, I'd hesitate...
120V is slightly more forgiving), you might want to check with an
electrician.
