rectifier failure, rectifier self-protection, the red LED is on. Once the  
alarm is gone, the red LED goes off.  
The controller of the PSE2500-A3 has two major functions:  
I. Monitoring the system operation status  
Inside PSE2500-A3 there is an AC sensor card, which can  
sample the AC input voltage. The sampled signal is sent into the  
controller for data processing. Once the input voltage is lower than the  
pre-set alarm level of the input low voltage, the controller reports an  
AC input under-voltage alarm. Likewise, if the input voltage is higher  
than the pre-set alarm level of the input high voltage, the controller  
reports an AC input over-voltage alarm.  
The sampled DC output voltage signal is also sent into the  
controller. Once the output voltage is lower than the pre-set alarm  
level of the output low voltage, the controller will reports a DC Low  
alarm. Likewise, if the output voltage is higher than the pre-set alarm  
level of the output high voltage, the controller reports a DC output high  
alarm.  
The rectifier communicates with the controller through RS485  
bus. The working status of the rectifier is passed to the controller in  
this way. Once the rectifier has an alarm, the information is passed to  
the controller. The rectifier failure alarm includes: AC input failure, DC  
output failure, fan failure, output high, over temperature, and module  
shut-down.  
II. Communicate with deamon systems  
The controller supports China national standard protocol YD/T  
1104-2001. User can apply this protocol to read system information or

AC input connection.  
AC cable for branch circuit must be sized as required by the U.S.  
National Electric Code (the cable length shall be minimum 1.5m and  
not exceed 4.5m) and /or local codes.  
Power plugs for the equipment appliance inlet must be plugged  
into independent wall socket outlet to ensure the earth connection  
through the supply. The socket outlet shall be installed near the  
equipment and shall be easily accessible.  
The AC utility connection must follow this procedure:  
1) Turn off the AC input switch.  
2) Plug the AC input power cord into the corresponding AC  
socket.  
For related connection position see figure 4-4.  
4.7 Initial Start-up  
The device is ready to be powered up. First, verify that all AC  
branch circuit breakers are OFF.

2) Verify that the “AC OK”, “DC OK”, and green LED are on and  
the fan operates on each rectifier.  
3) Wait approximately 10-30 seconds to allow the system to go  
through its start-up procedure.  
4) Verify that the green LED on the controller panel is on. All  
alarm LEDs should be off after all rectifiers are latched in  
place and all AC circuit breakers are closed.  
5) Using a digital voltmeter to verify that the plant voltage is  
approximately 54V, the default factory setting for the  
controller.  
6) Turn one the AC power input switch off to verify that the red  
alarm LED lights on the controller.  
7) For systems with more than one rectifier installed, turn the  
second AC input switch off to verify that the FAULT LED  
lights on the controller. Clear the alarms by turning the AC  
circuit breaker on.  
When the system shipped from the factory, normally all the  
systems parameters have been configured as the default value.
