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 ll Communicate with deamon systems The controller supports China national standard protocol YD T 1104 2001 User can apply this protocol to read system info
