Issue 02 (2017-10-23)
− A dual-bus system consists of one master and one slave BSC system, which are
specified by the customer. A BSC system cannot be the master and slave at the same
time. Specify master and slave systems during deployment. Set the master and slave
BSC systems to master and slave BSC modes respectively.
Paral. sys. hibernate
If the customer load is light, set parallel hibernation to alternate modules in hibernation
to prolong their service life as well as improve system efficiency.
Module cycle hiber. period (d)
A cycle of 1 to 100 days can be set. The parameter 30 days is set by default.
High ambient temperature alarm threshold (° C)
Set a value for an alarm to be generated when the ambient temperature reaches the preset
value.
Low ambient temperature alarm threshold (° C)
A warning is generated when the ambient temperature is lower than the parameter value.
Top outlet fan
If a top outlet fan is configured, check the fan running status after enabling this
parameter.
EOD restart
If the mains is not functioning normally, the UPS will transfer to battery mode. When
batteries reach the EOD threshold, the bypass is disabled, and EOD restart is enabled,
the UPS will restart as soon as the mains resumes.
If EOD restart is disabled, clear the alarm manually or enable the restart function for the
UPS.
EOD restart delay (min)
If EOD restart is set to Enable, the UPS starts working after EOD restart delay when
the mains recovers from an EOD power failure. The value range is 1–1440 min, and the
default value is 10 min.
Inverter async. alarm
Specifies whether the Inverter async. alarm is displayed when the inverter does not
track the bypass input. The normal power supply is not affected regardless of whether the
parameter is Enable or Disable.
Bus overvoltage recovery
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 (less than 420 V)
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. The default value is Enable.
Bus overvolt. recovery time
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
(less than 420 V) within Bus overvolt. recovery time. The default value is 5s.
