Battery Test This section includes all the parameters required for battery testing
through manual or automatic means. Configuration for manual test
duration and the system test end-voltage for manual battery test are
here along with the interval, start date, start time, time from last
battery on discharge BD, and enable/disable for automatic battery
test. The rectifier voltage during battery discharge testing and
system reserve time low alarm threshold are also available.
Automatic battery testing is factory disabled.
Recharge Amp Limit Enable or disable battery recharge limiting and set recharge current
limit. Recharge current limit is factory Disabled.
Voltage Imbalance User defined voltage threshold for a mid-string voltage alarm.
Range 1.4 - 3.0 Volts. Factory default is 1.7V.
*See Appendix B for detailed descriptions of the Thermal Compensation and Battery Test features and
parameters.
Contactor Interfaces: Various CPS6000 shelves and systems utilize contactors. The
QS840A can be configured to monitor external control boards that can be assigned to LVD
contactor control by appropriately configuring a unique board ID to a specific contactor
function. The controller can assign up to four IDs to boards used for controlling LVDs. Each
unique ID number can be assigned to one of the following LVBD 1 (Low Voltage Battery
Disconnect 1), LVLD1 (Low Voltage Load Disconnect 1), LVLD2 (Low Voltage Load
Disconnect 2), LVLD3 (Low Voltage Load Disconnect 3), or NONE. Each of these
assignments has its own unique programmable parameters. Selecting NONE removes the
ability of that particular remote distribution board to control and external LVD.
Disconnects: This section of the configuration menu contains the parameters associated with
the individual function assignments made in the previous section. Each LVD type (LVBD and
LVLD1-3) can individually be enabled or disabled. The contactor’s disconnect and reconnect
method of operation used by the controller can be programmed for each LVD. The method of
disconnect or reconnect can be based on reaching a system bus voltage threshold (Voltage) or
based on both reaching the system bus voltage threshold and an elapsed time from once the
system has been placed on discharge (BD) and at least two or more rectifiers are reporting AC
failures (Voltage+Time). The Voltage and Time mode of operation can also be selected for
reconnecting LVDs. In this case the elapsed time configured is the time from once the
reconnect voltage threshold has been reached.
