Shunt
Items here define the different shunts being monitored by the controller. One shunt, the Plant Shunt, is
monitored directly by the Pulsar Edge. Up to eight shunts can be monitored through various remote
distribution monitoring and control boards. The Pulsar Edge utilizes an RS485 serial communication
link to external distribution monitoring and control boards for shunt measurements and contactor
control. Up to eight of these external boards can be managed by the controller. Up to eight contactors
can be assigned to one of four independent control groups: LVBD, LVLD1, LVLD2, and LVLD3. External
distribution monitoring and control boards are identified by an address ID on the board. Assignments
are then made to appropriate operation types at the controller. The available Types are: Battery, Load,
and None. Shunt sizes for each assigned battery or load type must also be configured. All monitored
shunts are assumed to have a 50mV voltage rating. The current rating of each shunt is programmable
between 0 to 9999A. Systems shipped with the Pulsar Edge are appropriately pre-configured in the
factory for the right shunt values and assignments. The descriptions for the shunt measurements can
also be edited for additional resolution.
