Parameter List: 
 

NAME 

DESCRIPTION 

OPENUPSMODE 

OPENUPS mode 
0- Auto restart when Input Power is 
Present=YES 
1- Auto restart when Input Power is 
Present=NO  

UPS_CONFIG 

Configuration register. Used for enabling 
disabling modules. LSB bit is b0. 
b6- Stop impulse 
b5- Start impulse 
b4- Coulomb counter 
b3- A/D Low pass Filter module 
b2- Balance module 
b1- Charge module 
b0- Output module 
Default is all enabled 

UPS_INIT_DELAY_TOUT[s] 

Initial delay before starting the UPS. 
Default is 1 sec. 

UPS_VIN_MAX_SHUTDOWN[V] 

Max allowed input voltage. In case input 
voltage exceeds predefined value 
shutdown will be initiated. 
Default is 35V. 

UPS_VIN_MIN_START [V] 

If input voltage is above this threshold the 
UPS will start and take power from the 
input. 
Default is 11V. 

UPS_VIN_MIN_STOP [V] 

If input voltage is below this threshold the 
UPS will try to run on battery. 
Default is 6V. 

UPS_VCELL_MIN_START [V] 

If Vin is not present and all the battery 
cells are above this threshold the UPS 
can start and runs on battery 
Default is 11.7V 

UPS_VCELL_MIN_STOP [V] 

If VIN is not present and one of the 
battery cells is less than this threshold 
during the time period specified by  
UPS_VBAT_UVP_OFF_TOUT parameter 
the UPS will initiate shut down procedure. 
Default is 11.4V 

UPS_VBAT_UVP_OFF_TOUT [s] 

During this period battery cells are 
checked against 
UPS_VCELL_MIN_STOP. If cell voltage 
exceeds UPS_VCELL_MIN_STOP the 
timer is rearmed so it can filter unwanted 
noise in the system.
