Description
If this parameter is set to Enable, the
current at no load will be calibrated
once automatically. This function can be
used only when the UPS carries no load.
Set this parameter based on the output
interruption time acceptable to loads.
Circulating currents occur during the
transfer between bypass mode and
inverter mode, which impacts the
system. This parameter limits the
number of transfers between bypass
mode and inverter mode within 1 hour,
which ensures system security.
Monitors the current differences
between racks or modules. If this
parameter is set to Enable, the Mod.
Cur. Eql. Data can be viewed on the
running information page.
Specifies whether an Inverter
asynchronous alarm can be displayed
on the monitoring page when the
inverter does not track the bypass input.
Normal power supply is not affected no
matter whether this parameter is set to
Enable or Disable.
Specifies whether to automatically clear
the alarm and restart the power module
when the rectifier or inverter shuts
down due to a bus overvoltage alarm. If
Bus overvoltage recovery is set to
Enable, the bus overvoltage alarm is
automatically cleared, and the rectifier
and inverter automatically start when
the bus voltage recovers within Bus
overvolt. recovery time. When Bus
overvoltage recovery is set to Disable,
the bus overvoltage alarm cannot be
automatically cleared, and the rectifier
and inverter cannot automatically start.
