Description
threshold specified by this parameter.
Indicates whether to enable
emergency power-off (EPO). EPO is
performed only when this parameter
is enabled and the EPO switch is
triggered.
When EPO detection is changed
from Disable to Enable, check that
the EPO cable is connected correctly.
If this parameter is set to Enable, the
UPS detects the bus capacitor
lifespan.
When customer loads are light,
enable parallel hibernation to
alternate modules in hibernation
mode, which can prolong their
service life and improve the system
efficiency.
Indicates the rotation interval of
modules in hibernation mode. The
default value is 30, which means that
the hibernating module is rotated
every 30 days.
Indicates whether ECO bypass is
allowed to supply power in D.G.
mode. When the D.G. is connected to
the dry contact signal GEN:
 If this parameter is set to Enable,
the system can enter ECO bypass
mode when the D.G. supplies
power to the bypass and the ECO
function is enabled.
 If this parameter is set to Disable,
the system is not allowed to enter
ECO mode when the D.G.
supplies power to the bypass.
Enable or disable the memory check
function. If this parameter is set to
Enable, the control chip RAM
working status is checked regularly.
If this parameter is set to Disable,
regular check is disabled.
If this parameter is set to Enable, one
waveform can be stored manually.
