Chapter 4 Use Of The Controller 35
NetSure 531 AC1 Power Supply System User Manual
If the battery is configured and load current without instantly shocks, the system will operate under energy saving
mode, that is,
‘Save Enable’ is set to ‘Y’.
3. Advantage

Working on the best efficiency to save energy.

Balancing working hours of the rectifiers to prolong the lifetime of the rectifier.

In shutdown state, preventing rectifiers from damaged about AC inrush to reduce lightning fault.
4. Abnormal situation treatment

Switch off all the rectifiers when busbar voltage fails (DC over- voltage or low- voltage).

Switch on all the rectifiers when a rectifier alarm (Rect Not Respond) is generated.

Switch on all the rectifiers when an AC alarm (Mains Failure) is generated.

Switch on all the rectifiers automatically when the system has no controller or the communication is interrupted
between the rectifier and controller.

Delay implementation when the rectifier receives shutdown command, immediately execute when the rectifier
receives startup order.
The parameters of the energy saving are listed in Table 4-17.

The system type of the controller has been set according to the actual
instance before the controller is delivered with power supply system. You
need not to change the value except that the controller is replaced with a
new one.
After changing the type, the controller will restart automatically and the other
parameters will resume the default. You need to reset and change some
parameters according to the battery and equipment configured with system
Capacity 50Ah ~ 5000Ah 300Ah
The capacity of the total battery strings. You should set this parameter
according to the actual battery configuration
