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.
The factory defaults are the following:
• LVBD (Enabled)
Disconnect Mode (Voltage); Range: Voltage, Voltage+Time
Disconnect Voltage (42.0V); Range: 39-50V
Time Delay (0 min); Range: 0-300min
Reconnect Mode (Voltage); Range: Voltage, Voltage+Time
Reconnect Voltage (44.0V); Range: 39-55V
Time Delay (0 sec); Range: 0-300sec
• LVLD1 (Enabled)
Disconnect Mode (Voltage); Range: Voltage, Voltage+Time
Disconnect Voltage (42.0V); Range: 39-50V
Time Delay (0 min); Range: 0-300min

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.
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.
Enable or disable battery recharge limiting and set recharge current limit. Recharge current
limit is factory Disabled.
User defined voltage threshold for a mid-string voltage alarm. Range 1.4 - 3.0 Volts.
Factory default is 1.7V.
