Second Language OFF If you select ON, the UNITY/I displays all messages in its
second language. (For 60 Hz systems, this language is
Spanish.) The following languages are available, but they
must be ordered from the factory: Danish, Dutch, Finnish,
French, German, Italian, Polish, and Portuguese.
Adaptive slewrate ON OFF is used when mains frequency (AC input frequency) is
unstable.
Phone BEST before changing this parameter.
Battery monitor
reset
— ON will reset the battery monitor alarm and remove battery
monitor alarm messages from the alarm log.
ON also resets
all battery information (such as runtime); run a battery
monitor test again (see Section 302) to set battery
information to the correct levels.
(This parameter is only
active on units with a battery monitor. This is standard for
UT310-UT330 models with internal batteries and optional
for UT310-UT3220 models with external batteries.)
Battery monitor test — This test calculates the condition of the batteries. See
Section 302 for more information. (This parameter is only
active on units with a battery monitor test option; the
monitor is standard for UT310-UT330 models with internal
batteries and optional for UT310-UT3220 models with
external batteries.)
Battery capacity test — This test determines how much backup time (runtime) is
available. See Section 303 for more information.
M3 startup — Not applicable.
Boost charge OFF ON sets the unit for 8 hours (programmable) of continuous
boost (equalize) charge. If you would like to change the time
to more or less than 8 hours, call BEST’s Worldwide
Service.
Bypass operation OFF
ON switches the system into static bypass operation.
The
unit must be programmed for static bypass operation
before an external bypass switch is activated
. If this is not
done, power to the loads may be disturbed.
When you
operate the UPS in bypass, it will not charge the
batteries.
Autostart OFF If this is set to ON, the unit will automatically start
whenever
mains (AC line) is applied after 30 seconds.
(Some units have been programmed for autostart at the
factory.)
CAUTION: When this parameter is on, the unit
automatically switches on and provides power to the
loads whenever mains is available. When you are
servicing the unit or loads, make sure this is set to OFF.
