Table 30 Boost Configuration
ISHVSD This is an Independent High Voltage Shutdown threshold during the Boost
mode of operation that is sent to and stored in the rectifiers that is used by
each rectifier for independent high voltage monitoring.
The threshold can be set from -52.00V to -60.00V or +26.00 to +30.00V with a
factory default setting of -58.50 and +29.25V for 48V and 24V systems,
respectively.
Voltage Alarms Has the ability to set similar DC bus level alarms during Boost as found with the
Float mode of operation. This includes Very High Major, High Minor, and BD.
Very High Major
This is the High Voltage Shutdown Alarm (HVSD) threshold for the primary DC
bus during Boost that when it is reached the controller will send out the HV
shutdown command to the serial rectifiers so that the offending rectifier will
shut itself down. The threshold can be set from -50.00V to -60.00V or +25.75
to +31.75V with a factory default setting of -57.00 and +28.24V for 48V and
24V systems, respectively.
High Minor
This alarm indicates an abnormally high output voltage on the secondary DC
bus during Boost. The controller does not attempt to shut the offending unit
down. The threshold can be set from -50.00V to -60.00V or +25.75 to +31.75V
with a factory default setting of -56.00 and +27.74V for 48V and 24V for
systems, respectively.
BD
Primary DC bus threshold setting used during the Boost mode of operation
that determines when the system is determined to be operating either
completely or partially on battery reserve.
The threshold can be set from -46.00V to- 55.00V or +23.00 to +28.00V with a
factory default setting of -51.00V and +25.54V for 48V and 24V systems,
respectively.
Max Duration Defines the maximum time duration the system can remain in the Boost mode
of operation.
Value set from 1 to 80 hours. The factory default setting is 5 hours.
Automatic Enables or Disables the automatic boost feature. Boost may be configured to
use a “Timed” or “Current” based algorithm. When set to Time, Boost will
utilize a multiplication factor of the actual time of the last BD. When set to
Current, Boost will end once the monitored battery current reaches the
programmed threshold. These values can be modified through the remote
interfaces.
The factory default setting for Automatic Boost is Disabled.
