NAME

       fentonups - Driver for Fenton Technologies (Megatec protocol) UPS equipment

NOTE

       This  man  page	only documents the hardware-specific features of the fentonups driver.	For information about the core driver, see nutups-
       drv(8).

SUPPORTED HARDWARE

       fentonups primarily supports Fenton Technologies models such as the PowerPal, PowerPure and PowerOn lines.  Due to the common  heritage	of
       UPS equipment, it generally supports other hardware that also uses the Megatec protocol.

       At  the	time  of  this writing, the PowerGuard PG-600 and PowerCom SMK-800A are recognized and supported.  Other Megatec units should also
       work, but they will generate a warning since their battery information is not known.

EXTRA ARGUMENTS

       This driver does not support any extra settings in the ups.conf(5).

BUGS

       The battery percentage is derived from the voltage data that the UPS returns, since the UPS doesn't return that value  directly.   On  some
       hardware,  the charge will remain at 100% for a long time and then drops quickly shortly before the battery runs out.  You can confirm from
       the BATTVOLT readings that this is a problem with the UPS and not this driver.

       Similarly, the float from the charger in some models forces the battery charge percentage back up to 100% immedately  after  the  UPS  goes
       back on-line, so you can't tell when it is really recharged.

       Dead/broken  batteries  can't  be reported reliably.  If your UPS kills the load instantly or within seconds of starting the inverter, your
       batteries probably need to be replaced.	Recently, a pair of 3.5 hour outages here (thanks CPS!) finally killed my batteries.  You may have
       to run a manual test from the front panel before the "replace battery" LED will light.
