[Nut-upsuser] Brand new EATON 3S700DIN (mfr.date 09/28/14) doesn't wait for LB flag

Wed Jul 29 10:47:22 UTC 2015

Hi Philip,

I've updated NUT to 2.7.3 and finally found the root cause for the
unexpected shutdown:
It is recommended to increase pollinterval to 10 seconds in ups.conf  for
usbhid-ups driver due to a known issue:
http://www.networkupstools.org/docs/man/usbhid-ups.html
Default DEADTIME=15 in upsmon.conf was triggering shutdown. Increasing the
value to 30 seconds resolved the issue.

Now when NUT receives LB flag, it shuts down all powered devices correctly.
However, upsc returns the following:
-ups.alarm: Battery voltage too low!
-ups.status: ALARM OL

Only if to power off the UPS and power on it again, correct status is
displayed:
-ups.status: OL

Dear developers,
is my understanding correct, that this might be related to the ISSUE #1
described below, since there is 'No space left on the device' and the UPS
needs to be reset by powering it off?

ISSUE# 3 seems to be resolved for me by correct configuration.
ISSUES #1 & 2 still persist.

Thanks,
Sergey
