System Startup
Visually inspect the installation thoroughly.
After completing the system installation and power system wiring, perform the following startup and test procedure
to ensure proper operation:
6.1
Check System Connections
•
Ensure power is off, battery breaker is off (if applicable), and all modules are removed from the shelf.
•
Triple-check the polarity of all connections.
6.2
Power the Converter Shelf
1.
Provide power to the converter shelf either from a rectifier shelf or batteries.
NOTE:
The CXCI/CXCI+ controller is powered from the p24V bus.
2.
After a brief validation cycle, the C LEDs indicate the status of system alarms.
3.
Login to the controller as follows:
a.
Set the laptop IP Network settings (
Start > Control Panel
)
•
IP address: 10.10.10.202
•
Subnet mask:255.255.255.0
b.
Turn off Pop-up Blocker.
c.
Enter 10.10.10.201 in the web address bar of the laptop.
d.
Login to the CXC controller:
•
Username: your company name and your initials
•
Password: 1234
•
Language selection: English
4.
Use the CXC controller to test the functionality of various module alarms and controls.

Converter Operation and Programming via the CXCI/CXCI+
The existing CXC Controller Signals category now includes signals for Converter Load Voltage and Converter
Load Current; by default, Average Conv. Output Voltage and Total Conv. Output Current are used respectively.
6.3.1
Load Current in a Rectifier/Converter System
For proper operation of Charge Current Control and Power Save, the system load current must include the current
drawn from the rectifiers used to power the converters. Depending on the location of the current shunt in the
system, it may be necessary to modify the Load Current equation to add the Total Converter Input Current.
To view the load current of the system load, without the influence of the Converter Input Current, a custom signal
can be created; for example, if Load A powers some equipment and Load B is the current drawn by the
converters, then the equation for Load A would be: Total Rectifier Output Current - Total Converter Input Current.
6.3.2
Recommendation for Converter Redundancy
During firmware upgrade (programming) of the converter, the converter being programmed will be turned off and
not deliver any power. This is largely due to the way in which the converter begins operation after programming.
The power-up sequence for a converter is to start with 0V and 0A for a Start Delay of one through ten seconds.
After this period has expired, the converter will ramp up the Output Voltage and Current Limit values to the
appropriate settings in about one second. Furthermore, since the converter will be off for at least this amount of
time, the present implementation turns off the converter before the programming. The programming time is added
to the Start Delay to provide the total amount of time for which the converter will be off or out-of-service.
Therefore, with one redundant converter in a system, the load will still receive power from the other converters
while one of them is being programmed.
