Daily fault handling method
1 AC blackout
When the power failure time is not long, the DC power supply is charged by the battery. If the cause of power failure is unknown or the time is too long, it is necessary to start the oil engine power generation. It is suggested that the oil turbine generator be switched to the power supply system at least 5 minutes after starting, so as to reduce the influence of the starting process of the oil engine on the power supply equipment
2 AC overvoltage
The setting value is too low, if too low, should be changed. The general overvoltage does not affect the system work, and when the power voltage is greater than 305V, the rectifier module will stop working. Therefore, for long-term overvoltage power supply network, it is necessary to consult with relevant power network maintenance personnel to improve the power grid
3 AC undervoltage
The setting value is too high, if too high, should be changed. If the mains voltage is lower than 176V, the rectifier module will limit the power output, lower than 80V will stop working. Therefore, for the long-term undervoltage power supply network, it is necessary to consult with the relevant power network maintenance personnel to improve the power grid
4 DC overvoltage alarm
1. check the DC output voltage and monitoring module "DC overvoltage alarm" setting value, if the set value is unreasonable, please change. 2. find the rectifier module that causes overvoltage alarm. The AC input switch of all rectifier modules is disconnected under the condition that the battery can be supplied normally. Then, the AC input switch of the module is connected one by one. When the AC input switch on a module is switched on, the system appears overvoltage alarm again, then the module is over voltage, please replace it
5 DC undervoltage alarm
1. check the DC output voltage and the monitoring module "DC undervoltage alarm" setting value, if the set value is unreasonable, please change. 2. check whether the city power outage, such as power outages, disconnect part of the load to extend the working time of the entire power supply system. 3. check whether the rectifier module exits, that is, there is no output current, if necessary, please replace the module. 4. check the total load current. If the load current exceeds the total float total output current rectifier module, you need to remove the part load, or increase the total current of the rectifier module, rectifier module over load current of 120%, and at least 1 rectifier module redundancy backup
6 load branch break, battery branch break
Check the branch circuit breaker or fuse is disconnected (check the open position of the handle, or the measurement of dissolved silk voltage, the voltage is close to normal 0V fuse). If you disconnect, look for the cause and troubleshoot it. Otherwise, the alarm circuit fault, please contact Emerson
7 battery protection
1. check whether the power outage, the battery voltage drops to the battery protection voltage set value or discharge time to the battery protection time setting value. 2. check whether manual control of battery protection
8 module failure
The red indicator light on the rectifier module panel is lighted. The AC input of the rectifier module is cut off, and then the module is restarted after a period of time. If it is still warning, replace the module
9 module protection
Check whether the mains voltage is greater than the AC overvoltage point (305V) or less than the AC undervoltage point (80V). For long-term overvoltage or undervoltage power supply network, need to consult with the relevant power network maintenance personnel to change
