Shunt Monitors: Versions of the CPS6000 are equipped with a battery or load shunt. For
those shelves that do not have shunts these settings are not used. The QS840A utilizes RS485
serial communication to external distribution monitoring and control boards for shunt
measurements and contactor control. Up to four external boards can be controlled. These
boards must be identified by assigning them an address and an appropriate operation. The
following is shown for completeness.
ID1-4 The operation “Type” of each shunt monitoring circuit on system
distribution boards 1-4 must be assigned based upon actual
system implementation. The operational Type may be: None (For
no shunt), Battery (Monitoring battery currents), and Load (for
load currents).
ID1-4 Rating The current rating of each shunt being monitored by the system
distribution boards 1-4 must be configured based upon actual
system implementation. All shunts are assumed to be 50mV. The
current rating may be from 0-9999 Amps. The factory default is
300A.
Redundancy: Enable or disable rectifier redundancy mode. When Enabled, an alarm is
automatically generated when the rectifier capacity On-line in the system falls below N+1
based on the present system load. The factory default for this feature is disabled.
Batteries: Set up the following battery information:
Battery Type The type of batteries used in the system and can be set for Valve-
Reg (VRLA), Flooded, NiCd, Li-LMP, and Li-ELiTE type
batteries. Factory default is Valve-Reg.
Installed Capacity Total installed battery capacity assuming an 8-hour rate (0-30000
AH). Factory default is 0.
Battery Strings Total number of battery strings attached to the system
End Of Discharge
Voltage The user defined system bus voltage at which the batteries are
considered to be at the end of their reserve capability for manual
battery testing (End of Discharge). This end-of-discharge voltage is
used for automatic and opportunistic reserve time calculations. It
has a range of -36.00 to -48.00V. The system factory default is -
44.00V.
Battery Temp
Management* This section includes all the parameters required for thermal
management of the batteries. These items include the ability to
enable/disable thermal compensation for high and low temperatures
and set the slope decrease and increase rates, respectively. There is
also a “High Temperature alarm threshold”, “High Temperature
Disconnect” feature.
Thermal compensation features are factory defaulted Enabled.
