6.4.7 Boost (BST) Mode
This feature will allow a transition to BST mode when a user-defined condition (custom alarm) is false.
NOTE: Activation is manual and certain conditions must be met to prevent damage to the load.
A custom alarm must be created to include all the desired factors that must be taken into account before
activating BST mode. This mode will then only be permitted if the alarm is false.
Once activated, BST mode concludes with a timeout or whenever the status of the custom alarm is true and
reverts to FL mode. BST mode can also be cancelled if the conditions that are required in order to activate BST
mode have changed.
6.4.7.1 Enable
This menu item enables the Supervisor to control the CXC’s Boost Mode feature.
6.4.7.2 Voltage
This menu item controls the deviation of the Boost Mode voltage.
6.4.7.3 Timeout
This menu item controls the duration of the Boost Mode.
6.4.7.4 Inhibit
This menu item enables the Supervisor to assign the Custom Alarm (see 6.5.3 Configure
Alarms) number between 1 and 20.
6.4.7.5 Battery Properties (See 6.4.8)
The “Battery Properties” button at the bottom of the Boost Mode window is a link to the Battery
Properties window.
The return path (the menu structure) will remain intact; i.e., the user will return through the
window where the Battery Properties button was tapped.
6.4.8 Battery Properties
Battery Properties contain information that is provided by the battery manufacturer. This data is used by Charge
Current Control, Battery Monitor, and Temperature Compensation.
6.4.8.1 Capacity Rating (20-Hour Rate)
This menu item will enable the Supervisor to set the specified total capacity of the battery string
(derived from battery manufacturer’s specifications and should correspond to the C/20 Capacity
if possible). This value will be used in the calculations for charge current control function and
capacity estimation.
NOTE: If multiple strings are used, this value will represent the total combined capacity
of all battery strings summed together.
6.4.8.2 Capacity Calibration
Selecting this Item will enable the Supervisor to enter a value to effectively “calibrate” the
Battery Capacity. This is necessary when the batteries are first commissioned and whenever an
independent test is done to measure the battery’s capacity.
6.4.8.3 Open Circuit Voltage
This menu item will enable the Supervisor to set the open circuit voltage (derived from battery
manufacturer’s specifications).
