NetSure 211 C45 Embedded Power Supply System User Manual
3.2 Basic Settings
When the system is put into service for the first time, the parameters of the monitoring module must be set based on
the actual system configuration,
battery number and capacity, user’s charge current limiting and other functional
requirements. Only after that can the monitoring module display system operation information and control the output.
To change the settings, enter the main menu Settings (password: 1) Battery Settings Batt. Selection
submenu, set the
‘Mode’ parameter to ‘Manual’, and then return to the submenus of Battery Settings menu to set the
parameters For detailed setting method, see SCU + Series Monitoring Module User Manual .

The system model has been set correctly in factory before delivery, check that the setting agrees with
the actual system (48V/SET)

The battery string number set at the monitoring module should be the same as the number actually
connected (Default: 2)

Set the battery capacity according to the total capacity of all the battery connected to the system.
Default: 300Ah

Configure the temperature compensation coefficient according to
the battery manufacturer’s
requirement. Setting range: 0mV/°C ~ 500mV/°C. Default: 72mV/°C (if no temperature sensor is
installed, do not set this parameter)

Set the charge current limit according to your needs. Setting range: 0.1C
10
~ 0.25C

)

Set the monitoring module according to the voltage suggested by the battery supplier.
Float Charge (FC) voltage range: 42V ~ Boost Charge (BC) voltage. Default: 53.5V.
BC voltage range: FC voltage ~ 58V. Default: 56.4V.
For batteries that do not need BC, set the BC voltage to FC voltage plus 0.1V

Measure the battery voltage with a multimeter and record it. Enter main menu Maintenance
(password: 1) RectTrim submenu. Set the output voltage of the rectifier to the value of the battery
voltage. Insert the battery fuse. Set the output voltage of the rectifier to 53.5V

Enter the Batt. Selection submenu. Set the
‘Mode’ parameter to ‘Auto’ 
Note*: if the capacity of the battery is smaller than 50Ah, set the
‘Capacity’ to 50Ah
3.3 Alarm Check And System Operation Status Check
Alarm check
Check that all functional units can trigger alarms and the alarms can be displayed on the monitoring module.

Pull out one rectifier
, and the ‘Rect N Com Failure’ alarm should be triggered. Insert the rectifier in, and
the alarm should disappear. Repeat the same procedures on other rectifiers

Switch off battery MCB 1,
and the ‘Batt1 Failure’ alarm should be triggered. Switch on battery MCB 1,
and the alarm should be cleared. Repeat the same on battery MCB 2

Switch off a load MCB connected to load, and the alarm
‘Load Fuse N Failure’ should be triggered.
Switch on the load MCB, and the alarm should be cleared. Repeat the same on other load MCBs

Switch off the battery MCBs. Keep only one rectifier in operation. Through the monitoring module,
adjust the rectifier FC voltage to make it lower than the alarm point. The alarm
‘DC Voltage Low’ should
be triggered

Keep the rectifiers in operation. Set through the monitoring module the battery management parameter
to
‘Manual’. Enter the maintenance menu at the monitoring module. Select ‘Disconnect’ and confirm it.
The battery protection contactor should be open, and the
‘BLVD’ alarm should be displayed at the
monitoring module

Note: The monitoring module will give alarms approximately 10s after the alarms are triggered. Enter main menu Operation to
view the alarm information
