Float Set Point Parameter sets the value that primary (rectifier) DC bus will be set and
regulated. System Float Voltage set-point adjustable from -42.00V to -
56.50V with a factory default of -54.48V for 48V VRLA power
systems +21.00V to +28.00V with a factory default of +27.24 for 24V
VRLA power systems.
Boost Set Point DC bus voltage set-point during the Boost mode of operation. Boost
(set point) is adjustable from -48.00V to -58.00 with a default setting
of -55.20V and from +22.00V to +30.00 with a default setting of
+27.24V.
Float/Boost Internal
High Voltage
Shutdown This is an Independent High Voltage Shutdown threshold during the
Float or Boost mode of operation that is sent to and stored in the
rectifiers and is used by each rectifier for independent high voltage
monitoring. The threshold can be set from -50.00V to -60.00V with a
default setting of -58.50V and from +26.00V to +31.75V with a
default setting of +29.25V.
Float/Boost Current
Limit Adjustable from 30-110%. At 100% or greater the rectifier will output
its nameplate rating and truly act as constant power rectifiers. Settings
below 100% will be current limited to that percentage of the rectifier’s
name plate current rating.
Rectifier On
Threshold The system DC bus threshold that rectifiers placed into Standby will
automatically be turned on. This value can be set between -40.00V and
-51.00V with a default of -44.00V and +20.00V and +25.00V with a
default of +22.00V.
Enable Redundancy
Number Of
Redundant
Rectifiers When Enabled, an alarm is automatically generated when the rectifier
capacity On-line in the system falls below N+X based on the present
system load. X is the desired number of rectifiers to check for
redundancy. The factory default for this feature is Enabled and X=1.
Remote Rectifier In
Standby Provides the ability to disable or enable the capability of placing a
rectifier into Standby operation through remote means such as the
network, modem, or local Craft port.
Enable Remote
Group Standby When enabled, provides the ability to hold off a user configured group
of rectifiers when appropriate contact closure is received on the
assigned input or when the command is issued from the Maintenance
page or issued remotely over the network or Craft port. The feature is
also called Group Standby (TR).
Note: appropriate Pulsar Edge controllers have this feature utilize the
IN007 input typically located on J1.1 of appropriate CP and SPS
shelves. This input is labeled as PBT/TR. To use the input for PBT the
Group Standby feature must be disabled and the Battery Manual Test
Type must be enabled. This input can also serve as a general purpose
input by configuring the alarm assignment to something else. The
factory default for the Group Standby feature is Disabled.
Remote Group
Standby Rectifiers Provides a list of all system rectifiers. Users can select specific
rectifiers to put into Remote Standby by checking the appropriate
boxes. The factory default for this feature is to have no rectifiers
assigned.
Energy Efficiency
Enable When Enabled, the controller will engage its Adaptive Rectifier
Management (ARM) algorithm to optimally manage the system
