Table 29 Converters Configuration
Disconnect Converter input voltage threshold to be used to place all converters into
Standby.
The converter disconnect threshold is adjustable from -40.0V to -50.0V and
+20.0V to +25.0V with a factory default of -46.0V and +23.0V for 24V and 48V
output converters, respectively.
Reconnect Converter input voltage threshold to be used to return all converters from
Standby to On.
The converter reconnect threshold is adjustable from -44.0V to -54.0V and
+22.0V to +27.0V with a factory default of -52.0V and +26.0V for 24V and 48V
output converters, respectively.
Voltage Alarms Has the ability to set similar secondary DC bus level alarms as found with the
rectifiers and the primary DC bus. This includes Very High Major, High Minor,
and Very Low voltage.
Very High Major
This is the High Voltage Shutdown Alarm (HVSD) threshold for the secondary
DC bus that when it is reached the controller will send out the HV shutdown
command to the serial converters so that the offending converter will shut
itself down. The threshold can be set from -50.0V to -60.0V or +25.0 to +30.0V
with a factory default setting of -56.00 and +28.5V for 48V and 24V converter
outputs, respectively.
High Major
This alarm indicates an abnormally high output voltage on the secondary DC
bus. The controller does not attempt to shut the offending unit down. The
threshold can be set from -48.0V to -60.0V or +24.0 to +30.0V with a factory
default setting of -54.00 and +27.0V for 48V and 24V for converter outputs,
respectively.
Very Low
Secondary DC bus alarm threshold used to indicate something dragging the
bus to an undesired voltage level or an incorrect setting. The threshold can be
set from -40.0V to -54.0V or +20.0 to +27.0V with a factory default setting of -
46.0V and +23.0V for 48V and 24V for converter outputs, respectively.
Boost
The Boost function allows battery charging to be expedited by raising the system voltage to Boost level for a
set time. The following boost mode parameters are set in this area of the menu system:
Table 30 Boost Configuration
Set Point Primary DC bus voltage set-point during the Boost mode of operation.
Boost (set point) is adjustable from -48.00V to -58.00V and 22.00 to 30.00V in
0.1V increments. The factory default setting is -55.20V and 27.24V.
