NAME

       nutdrv_qx - Driver for Q* protocol serial and USB based UPS equipment

NOTE

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

SUPPORTED HARDWARE

       The nutdrv_qx driver is known to work with various UPSes from Armac, Blazer, Energy
       Sistem, Fenton Technologies, General Electric, Hunnox, Masterguard, Mustek, Powercool,
       Voltronic Power, SKE (rebranded by many, many - have I said many? - others...

       Long story short: if your UPS came with a software called Viewpower, chances are high that
       it works with this driver with one of the voltronic* protocols or with the mecer one), and
       many others.

       The NUT compatibility table lists all the known supported models. Keep in mind, however,
       that other models not listed there may also be supported, but haven’t been tested or
       reported back.

       All devices with a serial interface and many with a USB interface are supported.

EXTRA ARGUMENTS

       You may need to override or provide defaults for some values, depending on the make and
       model of your UPS.

       The following are the ones that most likely will need changing (see ups.conf(5)):

       ondelay = value
           Time to wait before switching on the UPS (seconds). This value is truncated to units
           of 60 seconds.

           Note that a value below 3 minutes, may cause earlier firmware versions to not switch
           on automatically, so it defaults to 3 minutes (i.e. 180 seconds).

           This option provides a default value for ups.delay.start that will then be used by the
           driver in the automatic shutdown sequence (i.e. calling the driver with the -k option,
           calling upsdrvctl(8) with the shutdown option or when the FSD flag is set and
           upsmon(8) enters its shutdown sequence): however you can change this value ‘on the
           fly’ for the actual session, only for the use with instant commands, setting
           ups.delay.start with upsrw(8).

       offdelay = value
           Time to wait before shutting down the UPS (seconds). This value is truncated to units
           of 6 seconds (less than 60 seconds) or 60 seconds (more than 60 seconds). Defaults to
           30 seconds.

           This option provides a default value for ups.delay.shutdown that will then be used by
           the driver in the automatic shutdown sequence (i.e. calling the driver with the -k
           option, calling upsdrvctl(8) with the shutdown option or when the FSD flag is set and
           upsmon(8) enters its shutdown sequence): however you can change this value ‘on the
           fly’ for the actual session, only for the use with instant commands, setting
           ups.delay.shutdown with upsrw(8).

       stayoff
           If you set stayoff in ups.conf(5) when FSD arises the UPS will call a shutdown.stayoff
           shutting down after ups.delay.shutdown seconds and won’t return (see KNOWN PROBLEMS),
           otherwise (standard behaviour) the UPS will call shutdown.return shutting down after
           ups.delay.shutdown seconds and then turn on after ups.delay.start seconds (if mains
           meanwhile returned).

       protocol = string
           Skip autodetection of the protocol to use and only use the one specified. Supported
           values: bestups, hunnox, masterguard, mecer, megatec, megatec/old, mustek, q1,
           voltronic, voltronic-qs, voltronic-qs-hex and zinto.

           Run the driver program with the --help option to see the exact list of protocol values
           it would currently recognize.

           Note that if you end up using the q1 protocol, you may want to give a try to the
           mecer, megatec and zinto ones setting the novendor/norating flags (only one, or both).

       pollfreq = num
           Set polling interval for full updates, in seconds, to reduce the message traffic.
           Between two polling requests, the driver will do quick polls dealing just with
           ups.status at an interval specified by the pollinterval driver option (details in
           ups.conf(5)). The default value is 30 (in seconds).

       If your UPS doesn’t report either battery.charge or battery.runtime you may want to add
       the following ones in order to have guesstimated values:

       default.battery.voltage.high = value
           Maximum battery voltage that is reached after about 12 to 24 hours charging. If you
           want the driver to report a guesstimated battery.charge, you need to specify this (see
           BATTERY CHARGE GUESSTIMATION).

       default.battery.voltage.low = value
           Minimum battery voltage just before the UPS automatically shuts down. If you want the
           driver to report a guesstimated battery.charge, you need to specify this (see BATTERY
           CHARGE GUESSTIMATION).

       default.battery.voltage.nominal = value, override.battery.voltage.nominal = value
           Some devices show a wrong nominal battery voltage (or none at all), so you may need to
           override or set a default value.

       override.battery.packs = value
           Some devices "natively" report just a part of the total battery voltage (see also
           battery_voltage_reports_one_pack below).

           For instance, if battery.voltage.nominal is 24 V, but it reports a battery.voltage of
           around 2 V, the number of battery.packs to correct this reading would be 12.

           The driver will attempt to detect this number automatically, but if this fails
           somehow, you may want to override this value.

           Note that this is primarily useful for "guesstimation" of battery.charge and/or
           battery.runtime (with runtimecal setting), if those readings are not provided by the
           device directly.

       battery_voltage_reports_one_pack
           Some devices "natively" report just report a part of the total battery voltage (see
           also override.battery.packs above, if that value is not reported by the device or
           properly guessed by the driver otherwise).

           If this flag is set, most of the subdrivers (except those which know about more
           complicated device-specific nuances, currently: ablerex, masterguard and
           voltronic-qs-hex) adjust their ultimately reported battery.voltage value as a multiple
           of battery.packs and "native" battery.voltage).

           Note this is primarily useful for consistent diagnostics and graphing of the numbers,
           and should not impact the "guesstimation" of battery.charge and/or battery.runtime -
           so rather a cosmetic adjustment, than critical.

       runtimecal = value,value,value,value
           Parameter used in the (optional) runtime estimation. This takes two runtimes at
           different loads. Typically, this uses the runtime at full load and the runtime at half
           load. For instance, if your UPS has a rated runtime of 240 seconds at full load and
           720 seconds at half load, you would enter

               runtimecal = 240,100,720,50

           The first load should always be higher than the second. If you have values available
           for loads other than 100 and 50 % respectively, you can use those too, but keep them
           spaced apart as far as reasonably possible. Just don’t get too close to no load
           (prediction of runtime depends more on idle load for the battery then).

       chargetime = value
           The time needed to fully recharge the battery after being fully discharged. If not
           specified, the driver defaults to 43200 seconds (12 hours). Only used if runtimecal is
           also specified.

       idleload = value
           Minimum battery load used by the driver to estimate the runtime. If not specified, the
           driver defaults to 10%. Only used if runtimecal is also specified.

   BESTUPS, MECER, MEGATAEC, MEGATEC/OLD, MUSTEK, Q1, VOLTRONIC-QS, VOLTRONIC-QS-HEX, ZINTO
       PROTOCOLS
       ignoresab
           Some UPSes incorrectly report the ‘Shutdown Active’ bit as always on, consequently
           making the driver believe the UPS is nearing a shutdown (and, as a result, ups.status
           always contains FSD... and you know what this means). Setting this flag will make the
           driver ignore the ‘Shutdown Active’ bit.

   MECER, MEGATAEC, MEGATEC/OLD, MUSTEK, ZINTO PROTOCOLS
       ondelay
           The acceptable range is 0..599940 seconds.

       offdelay
           The acceptable range is 12..600 seconds.

       norating
           Some UPSes will lock up if you attempt to read rating information from them. Setting
           this flag will make the driver skip this step.

       novendor
           Some UPSes will lock up if you attempt to read vendor information from them. Setting
           this flag will make the driver skip this step.

   BESTUPS PROTOCOL
       ondelay
           The acceptable range is 60..599940 seconds.

       offdelay
           The acceptable range is 12..5940 seconds.

       pins_shutdown_mode = value
           Set shutdown mode functionality of Pin 1 and Pin 7 on the UPS DB9 communication port
           (Per Best Power’s EPS-0059) to value [0..6].

   MASTERGUARD PROTOCOL
       slave_addr = value
           Make the claim function verify it’s talking to the specified slave address (ups.id).
           Safeguard against talking to the wrong one of several identical UPSes on the same USB
           bus. Note that when changing ups.id (through upsrw(8)) the driver will continue to
           talk to the UPS with the new slave address, but won’t claim it again on restart until
           the slave_addr parameter is adjusted.

   Q1 PROTOCOL
       ondelay
           The acceptable range is 0..599940 seconds.

       offdelay
           The acceptable range is 12..600 seconds.

   VOLTRONIC-QS, VOLTRONIC-QS-HEX PROTOCOLS
       ondelay
           The acceptable range is 60..599940 seconds.

       offdelay
           The acceptable range is 12..540 seconds.

   VOLTRONIC PROTOCOL
       The following options are supported only by the voltronic protocol. Not all of them are
       available on all the UPSes supported by this protocol.

       ondelay
           The acceptable range is 0..599940 seconds.

       offdelay
           The acceptable range is 12..5940 seconds.

       battery_number = value
           Set number of batteries that make a pack to value [1..9]. This setting will change the
           charge and runtime estimation reported by the UPS.

       output_phase_angle = value
           Changes output phase angle to the provided value [000, 120, 180, 240]°.

       UPS CAPABILITY SETTINGS
           reset_to_default
               Reset capability options and their voltage and frequency limits to safe default
               values. (Doable only when the UPS is in Standby Mode)

               Note that setting this option will reset also ups.start.auto, battery.protection,
               battery.energysave, ups.start.battery, outlet.0.switchable, input.transfer.high,
               input.transfer.low, input.frequency.high and input.frequency.low.

           These UPSes can be fine-tuned to suit your needs enabling or disabling the following
           options (the driver should tell you which one the UPS is capable of on startup: the
           settable ones will be reported either are enabled or disabled in the logs):

           alarm_control = string
               Enable or disable alarm (BEEP!) [enabled/disabled]. Settable also ‘on the fly’
               with beeper.enable and beeper.disable instant commands.

           bypass_alarm = string
               Enable or disable alarm (BEEP!) at Bypass Mode [enabled/disabled].

           battery_alarm = string
               Enable or disable alarm (BEEP!) at Battery Mode [enabled/disabled].

           bypass_when_off = string
               Enable or disable bypass when the UPS is Off [enabled/disabled]. If enabled, AC
               will directly provide power to connected devices when the UPS is off.

           bypass_forbidding = string
               Enable or disable Bypass Forbidding [enabled/disabled]. If enabled, the UPS will
               not transfer to bypass mode under any condition.

           converter_mode = string
               Enable or disable Converter Mode [enabled/disabled]. When input frequency is
               within 40 Hz to 70 Hz, the UPS can be set at a constant output frequency, 50 Hz or
               60 Hz. The UPS will still charge battery under this mode.

           eco_mode = string
               Enable or disable ECO Mode [enabled/disabled]. When input voltage/frequency are
               within acceptable range, the UPS will bypass voltage to output for energy saving.
               PFC and INVERTER are still active at this mode. Settable also ‘on the fly’ with
               bypass.start and bypass.stop instant commands.

           advanced_eco_mode = string
               Enable or disable Advanced ECO Mode [enabled/disabled]. When input
               voltage/frequency are within acceptable range, the UPS will bypass voltage to
               output for energy saving. PFC and INVERTER are off at this mode.

           battery_open_status_check = string
               Enable or disable Battery Open Status Check [enabled/disabled]. If enabled, when
               the UPS is turned on, it will check if the battery is connected or not.

           site_fault_detection = string
               Enable or disable site fault detection [enabled/disabled]. If enabled, the UPS
               will beep when the input neutral and hot wires are reversed.

           constant_phase_angle = string
               Enable or disable Constant Phase Angle Function (output and input phase angles are
               not equal) [enabled/disabled].

           limited_runtime_on_battery = string
               Enable or disable limited runtime on battery mode [enabled/disabled].

       BYPASS MODE VOLTAGE/FREQUENCY LIMITS
           Variables to fine-tune voltage and frequency limits for Bypass mode. These limits are
           reset to safe default values by reset_to_default.

           If AC voltage and frequency are within acceptable range, Bypass mode will be used (If
           the UPS is capable of and it’s enabled).

           Since these values are device-specific, if your UPS support them, you will get their
           settable limits printed in the logs on startup.

           max_bypass_volt = value
               Maximum voltage for Bypass Mode (V).

           min_bypass_volt = value
               Minimum voltage for Bypass Mode (V).

           max_bypass_freq = value
               Maximum frequency for Bypass Mode (Hz).

           min_bypass_freq = value
               Minimum frequency for Bypass Mode (Hz).

       OPTIONS SPECIFIC FOR P31 UPSES
           The following options are available only on P31 UPSes.

           work_range_type = string
               Device grid working range for P31 UPSes [Appliance/UPS].

       TESTING
           This protocol comes with a couple of functions that are not enabled by default because
           of the lack of knowledge of some part of the communication protocol used by these
           UPSes by your friendly neighborhood developer. Since these functions are supposed to
           be queries to the UPS for some kind of information, they should not make your UPS go
           boom. So if you are brave enough to risk your UPS and attached devices' life to help
           the developers, this will be very appreciated.. Do it at your own risk.

           testing
               If invoked the driver will exec also commands that still need testing.

   SERIAL INTERFACE ONLY
       cablepower = string
           By default the driver will set DTR and clear RTS (normal). If you find that your UPS
           isn’t detected or the communication with the UPS is unreliable, you may try if clear
           DTR and set RTS (reverse), set DTR and RTS (both) or clear DTR and RTS (none) improves
           this situation.

   USB INTERFACE ONLY
       port = string
           Some value must be set, typically auto.

               Note
               This could be a device filesystem path like /dev/usb/hiddev0 but current use of
               libusb API precludes knowing and matching by such identifiers. They may also be
               inherently unreliable (dependent on re-plugging and enumeration order). At this
               time the actual value is ignored, but syntactically some port configuration must
               still be there.

       It is possible to control multiple UPS units simultaneously by running several instances
       of this driver, provided they can be uniquely distinguished by setting some combination of
       the vendor, product, vendorid, productid, serial, bus and/or device options detailed
       below. For devices or operating systems that do not provide sufficient information, the
       allow_duplicates option can be of use (limited and risky!)

       vendorid = regex, productid = regex, vendor = regex, product = regex, serial = regex
           Select a specific UPS, in case there is more than one connected via USB. Each option
           specifies an extended regular expression (see regex(7) for more information on regular
           expressions), which must match the UPS’s entire respective vendor/product/serial
           string (minus any surrounding whitespace), or the whole 4-digit hexadecimal code for
           vendorid and productid.

           Try lsusb(8) or running this NUT driver with -DD command-line argument for finding out
           the strings to match.

           Examples:

           •   -x vendor="Foo.Corporation.*"

           •   -x vendorid="051d*" (APC)

           •   -x product=".*(Smart|Back)-?UPS.*"

       bus = regex
           Select a UPS on a specific USB bus or group of buses. The argument is a regular
           expression that must match the bus name where the UPS is connected (e.g.  bus="002" or
           bus="00[2-3]") as seen on Linux in /sys/bus/usb/devices or lsusb(8); including leading
           zeroes.

       device = regex
           Select a UPS on a specific USB device or group of devices. The argument is a regular
           expression that must match the device name where the UPS is connected (e.g.
           device="001" or device="00[1-2]") as seen on Linux in /sys/bus/usb/devices or
           lsusb(8); including leading zeroes.

               Note
               device numbers are not guaranteed by the OS to be stable across re-boots or device
               re-plugging.

       busport = regex
           If supported by the hardware, OS and libusb on the particular deployment, this option
           should allow to specify physical port numbers on an USB hub, rather than logical
           device enumeration values, and in turn — this should be less volatile across reboots
           or re-plugging. The value may be seen in the USB topology output of lsusb -tv on
           systems with that tool, for example.

               Note
               this option is not practically supported by some NUT builds (it should be ignored
               with a warning then), and not by all systems that NUT can run on.

       allow_duplicates
           If you have several UPS devices which may not be uniquely identified by the options
           above (e.g. only VID:PID can be discovered there), this flag allows each driver
           instance where it is set to take the first match if available, or proceed to try
           another.

           Normally the driver initialization would abort at this point claiming "Resource busy"
           or similar error, assuming that the otherwise properly matched device is unique — and
           some other process already handles it.

               Warning
               This feature is inherently non-deterministic! The association of driver instance
               name to actual device may vary between runs!

               If you only care to know that at least one of your no-name UPSes is online, this
               option can help.

               If you must really know which one, it will not!

       usb_set_altinterface = bAlternateSetting
           Force redundant call to usb_set_altinterface(), especially if needed for devices
           serving multiple USB roles where the UPS is not represented by the interface number 0
           (default).

       subdriver = string
           Select a serial-over-USB subdriver to use. You have a choice between cypress, fabula,
           fuji, hunnox, ippon, krauler, phoenix, phoenixtec, sgs, snr, armac and ablerex.

           Run the driver program with the --help option to see the exact list of subdriver
           values it would currently recognize.

               Note
               When using this option, it is mandatory to also specify the vendorid and productid
               matching parameters.

       langid_fix = value
           Apply the language ID workaround to the krauler subdriver. This is mandatory for some
           devices to work (LDLC, Dynamix and others). You must provide value (0x409 or 0x4095),
           according to your device entry in NUT hardware compatibility list (HCL).

       noscanlangid
           If this flag is set, don’t autoscan valid range for langid.

       IMPLEMENTATION NOTES
           armac subdriver
               The Armac communication subdriver reproduces a communication protocol used by an
               old release of "PowerManagerII" software, which doesn’t seem to be Armac specific:
               its banner is "2004 Richcomm Technologies, Inc. Dec 27 2005 ver 1.1." Maybe other
               Richcomm UPSes would work with this — maybe better than with the older standalone
               richcomm_usb driver.

           fabula subdriver
               This subdriver, meant to be used with the megatec protocol, does not support the
               various test.battery commands. Plus, the shutdown.return command ignores the
               values set in ups.delay.start/ondelay and makes the UPS turn on the load as soon
               as power is back.

           hunnox subdriver
               This protocol subdriver is closely related to fabula one, with a few tweaks for
               devices not directly supported by that driver.

           fuji subdriver
               This subdriver, meant to be used with the megatec protocol, does not support the
               shutdown.stayoff and load.off commands. Plus, the shutdown.return command ignores
               the values set in ups.delay.start/ondelay and makes the UPS turn on the load as
               soon as power is back.

           krauler subdriver
               This subdriver, meant to be used with the megatec protocol, does not support the

           snr subdriver
               This subdriver, meant to be used with the megatec protocol, does not support the
               shutdown commands, i.e.: shutdown.return, shutdown.stayoff and load.off.

BATTERY CHARGE GUESSTIMATION

       Due to popular demand, this driver will report a guesstimated battery.charge and
       optionally battery.runtime, provided you specified a couple of the EXTRA ARGUMENTS listed
       above.

       If you specify both battery.voltage.high and battery.voltage.low in ups.conf(5), but don’t
       enter runtimecal, it will guesstimate the state of charge by looking at the battery
       voltage alone. This is not reliable under load, as this only gives reasonably accurate
       readings if you disconnect the load, let the battery rest for a couple of minutes and then
       measure the open cell voltage. This just isn’t practical if the power went out and the UPS
       is providing power for your systems.

                                battery.voltage - battery.voltage.low
           battery.charge =  ------------------------------------------ x 100 %
                             battery.voltage.high - battery.voltage.low

       There is a way to get better readings without disconnecting the load but this requires one
       to keep track on how much (and how fast) current is going in and out of the battery. If
       you specified the runtimecal, the driver will attempt to do this. Note however, that this
       heavily relies on the values you enter and that the UPS must be able to report the load as
       well. There are quite a couple of devices that report 0 % (or any other fixed value) at
       all times, in which case this obviously doesn’t work.

       The driver also has no way of determining the degradation of the battery capacity over
       time, so you’ll have to deal with this yourself (by adjusting the values in runtimecal).
       Also note that the driver guesses the initial state of charge based on the battery
       voltage, so this may be less than 100 %, even when you are certain that they are full.
       There is just no way to reliably measure this between 0 and 100 % full charge.

       This is better than nothing (but not by much). If any of the above calculations is giving
       you incorrect readings, you are the one that put in the values in ups.conf(5), so don’t
       complain with the author. If you need something better, buy a UPS that reports
       battery.charge and battery.runtime all by itself without the help of a NUT driver.

NOTES FOR THE PREVIOUS USER OF MEGATEC DRIVERS

       The nutdrv_qx driver having replaced the megatec ones, some configuration changes may be
       required by users switching to nutdrv_qx.

       Part of this, the following megatec options, in ups.conf(5), have to be changed:

       battvolts
           You need to use default.battery.voltage.high and default.battery.voltage.low

       dtr and rts
           You need to use cablepower

       ignoreoff
           This parameter can simply be discarded, since it was a wrong understanding of the
           specification.

NOTES FOR THE PREVIOUS USER OF BLAZER DRIVERS

       The nutdrv_qx driver having replaced the blazer ones, some configuration changes may be
       required by users switching to nutdrv_qx.

       Part of this, the following blazer options, in ups.conf(5), have to be changed:

       ondelay
           While the previous blazer drivers expected minutes, the new nutdrv_qx driver wants
           seconds.

       The following instant command has also been changed:

       test.battery.start value
           While the old blazer drivers expected a value in minutes, the nutdrv_qx driver wants a
           value in seconds.

NOTES FOR THE PREVIOUS USER OF BESTUPS DRIVER

       The nutdrv_qx driver having replaced the bestups one, some configuration changes may be
       required by users switching to nutdrv_qx.

       Part of this, the following bestups options, in ups.conf(5), are no longer supported by
       this driver:

       nombattvolt, battvoltmult
           See BATTERY CHARGE GUESSTIMATION.

       ID
           Discarded.

NOTES FOR THE PREVIOUS USER OF VOLTRONIC DRIVERS

       The nutdrv_qx driver having replaced the voltronic ones, some configuration changes may be
       required by users switching to nutdrv_qx.

       Part of this, the following voltronic options, in ups.conf(5), have to be changed:

       ondelay
           While the previous voltronic drivers expected minutes, the new nutdrv_qx driver wants
           seconds. It no longer defaults to 0 minutes but to 3 minutes (i.e. 180 seconds) for
           compatibility with the users switching from the old blazer drivers.

       battnumb
           This option has been renamed to battery_number.

       The following options are no longer supported by this driver, you can now change them more
       conveniently ‘on the fly’ calling upsrw(8) with the appropriate NUT variable - provided
       that your UPS supports them.

       battpacksbattery.packs

                            Set number of battery packs in
                            parallel [1..99]. This setting
                            will change the charge and
                            runtime estimation reported by
                            the UPS.

       battlowbattery.voltage.low

                            Set minimum battery voltage just
                            before the UPS automatically
                            shuts down. This setting will
                            change the charge and runtime
                            estimation reported by the UPS.

                            function [enabled/disabled]. If
                            enabled, for energy saving, the
                            UPS will auto off when there is
                            no load.

       cold_startups.start.battery

                            Enable or disable Cold Start

                            [enabled/disabled]. If enabled,
                            the UPS will cut off
                            programmable outlets after
                            backup time (set through
                            outlet.{1,2,3,4}.delay.shutdown)
                            arrives. If disabled, the UPS
                            will provide continuous power to
                            programmable outlets until the
                            battery is running out.

KNOWN PROBLEMS

       Some UPS commands aren’t supported by all models. In most cases, the driver will send a
       message to the system log when the user tries to execute an unsupported command.
       Unfortunately, some models don’t even provide a way for the driver to check for this, so
       the unsupported commands will silently fail.

       Both the load.off and shutdown.stayoff instant commands are meant to turn the load off
       indefinitely. However, some UPS models don’t allow this.

       Some models report a bogus value for the beeper status (will always be enabled or
       disabled). So, the beeper.toggle command may appear to have no effect in the status
       reported by the driver when, in fact, it is working fine.

       The temperature and load value is known to be bogus in some models.

   MASTERGUARD UNITS
       The driver is supposed to support both "new" A series (A700/1000/2000/3000 and their -19
       cousins) and E series (E60/100/200) but was tested only on A due to lack of E hardware.

   VOLTRONIC-QS UNITS
       Both load.off and shutdown.stayoff instant commands are known to work as expected (i.e.
       turn the load off indefinitely) only if mains is present, otherwise, as soon as mains
       returns the load will be powered.

       After issuing a shutdown.return instant command, the UPS won’t wait ondelay before
       powering on the load, provided the following conditions are met:

       •   if the load has been previously (no matter how long before) powered off through
           load.off/shutdown.stayoff and powered on through load.on/shutdown.stop and

       •   if AC wasn’t cut after issuing the load.off/shutdown.stayoff (i.e. the UPS didn’t turn
           itself off) and

       •   if there’s a power outage after issuing the shutdown.return command

       In this case, as soon as mains returns the load will be powered.

   VOLTRONIC-QS-HEX UNITS
       shutdown.return, load.off, and shutdown.stayoff instant commands are known to work as
       expected only if mains is present, otherwise, as soon as mains returns the load will be
       powered.

UPS WARNINGS (VOLTRONIC PROTOCOL)

       The UPSes supported by voltronic protocol report warnings through a 64bit flag
       (bit1bit2...bit63bit64) where 1 means that a warning arose, while 0 means no warning.
       Since more than one warning at a time can be signaled, and because of the limited space in
       the ups.alarm variable, if the length of the warnings exceeds that of ups.alarms variable,
       they will be reported as bits. If you want to know the explanation of that bit you can
       either watch the log or see the next table (unlisted bits equal to unknown warnings).
