The test is terminated by the occurrence of any of the following conditions:
• Initiating another Plant Battery Test. That is, once the test has been initiated, the test may be stopped by initiating
another test either through the controller.
• An alarm condition occurring. Any alarm condition that occurs during this test will result in the test being aborted.
The test will be aborted even if there is a contact
- closure still present on the PBT inputs.
• The test has continued for over 100 minutes.
• The plant voltage has dropped below 44V or the LVD safe voltage. In this case, the system will abort the test and
resume rectifier operation.
After the test has stopped, the plant will revert to the float mode. It may go to boost mode if the
auto
- boost feature has been enabled.
Boost Mode
Boost charging is a feature of the Pulsar Edge controller, which allows the user to temporarily raise the
plant voltage to a higher predetermined level to reduce the time needed to charge batteries. The
system may manually be placed in the boost
- mode through the front panel.
Note that the measured boost voltage may not exactly match the value chosen by the user if the
thermal compensation feature is enabled. This is because the Pulsar Edge performs thermal
compensated boost charging and will adjust the boost value based on the battery temperature per the
slope chosen by the user.
The plant will exit the boost mode and enter the float mode if any of the following occurs:
• The current flowing into the battery string(s) is less than the configured current threshold for at least 3 minutes.
• The duration of boost mode charging has reached the configured number of hours
• The controller receives either a Vsense Fail, Communication Fail, High - Voltage, Rectifier Fail alarm, Major Fuse
Alarm, or High - Battery Temperature alarms
• User sets the plant state to Float via the Craft port or remote interface.
Once initiated, the boost mode may be exited by placing the Plant State to Float.
Auto - Boost Charge
This feature may be enabled from the Craft port or remote interface. See Appendix B for details. When
enabled, the plant enters the boost
- charging mode of operation following a battery discharge once the
BD alarm has been retired, provided the duration of the discharge was greater than 4 minutes. The
controller will not enter the auto
- boost - charging mode if the discharge duration was less than 4
minutes. When in auto - boost mode, the controller raises the plant voltage to the value selected by the
user. The controller keeps the plant in this mode of operation for a minimum of 5 minutes. The exit
conditions for the Auto
- Boost Charge are the same as those for Boost Charge.
Redundancy Loss Function
This feature must be enabled from the Craft port or remote interface. The controller determines the
number of rectifiers present and compares the actual currents being drawn by the load to that
