NAME

6       fentonups  -  Driver  for  Fenton  Technologies  (Megatec protocol) UPS
7       equipment
8

NOTE

10       This driver is obsolete and has been replaced by the megatec(8) driver.
11       It will be removed somewhere in the near future.
12
13       This man page only documents the hardware‐specific features of the fen‐
14       tonups driver.  For information about  the  core  driver,  see  nutups‐
15       drv(8).

SUPPORTED HARDWARE

19       fentonups  primarily  supports  Fenton  Technologies models such as the
20       PowerPal, PowerPure and PowerOn lines.  Due to the common  heritage  of
21       UPS  equipment, it generally supports other hardware that also uses the
22       Megatec protocol.
23
24       At the time  of  this  writing,  the  PowerGuard  PG‐600  and  PowerCom
25       SMK‐800A are recognized and supported.  Other Megatec units should also
26       work, but they will generate a warning since their battery  information
27       is not known.

EXTRA ARGUMENTS

31       This   driver   supports   the   following  optional  settings  in  the
32       ups.conf(5):
33
34
35       lowbattvolt=decimal
36              Sets a user-defined battery voltage under which the driver  will
37              consider that the UPS is on "low battery" condition when running
38              on battery.  This allows initiating a system shutdown before the
39              UPS  signals  a  low battery status by itself, and may be useful
40              for some UPSes that don't have enough runtime left for  properly
41              shutting  down  the system when they start signaling a "low bat‐
42              tery" status.

BUGS

46       The battery percentage is derived from the voltage data  that  the  UPS
47       returns,  since  the  UPS  doesn't return that value directly.  On some
48       hardware, the charge will remain at 100% for a long time and then drops
49       quickly  shortly before the battery runs out.  You can confirm from the
50       battery.voltage readings that this is a problem with the  UPS  and  not
51       this driver.
52
53       Similarly, the float from the charger in some models forces the battery
54       charge percentage back up to 100% immedately after the  UPS  goes  back
55       on‐line, so you can't tell when it is really recharged.
56
57       Dead/broken  batteries  can't  be reported reliably.  If your UPS kills
58       the load instantly or within seconds of  starting  the  inverter,  your
59       batteries  probably  need to be replaced.  Recently, a pair of 3.5 hour
60       outages here (thanks CPS!) finally killed my batteries.  You  may  have
61       to  run a manual test from the front panel before the "replace battery"
62       LED will light.
