General Purpose Digital Outputs - Nuvation Energy NUV300-BC-12 Product Manual

stack_contactor[n].direction
▪
Set to 0 for a non-directional contactor that breaks any current
▪
Set to 1 for a directional contactor that breaks charge current
▪
Set to 2 for a directional contactor that breaks discharge current
stack_contactor[n].delay
▪
Time to wait before opening the contactor in the non-preferred direction
▪
When directional contactors are used, set this delay to a minimum of 1 second, otherwise set
the delay to 0 seconds
stack_contactor[n].installed
▪
Set to 1 to indicate a contactor is physically wired into the BMS
▪
Only installed contactors will flag hardware failures via the stack_contactor[n].coil_error or
stack_contactor[n].feedback_error
stack_contactor[n].feedback_enable
▪
Set to 1 to enable contactor feedback from a configured input
▪
State mismatches between stack_contactor[n].feedback_value and stack_contactor[n].value will
result in stack_contactor[n].feedback_error being set to 1
For advanced applications, contactor outputs may be configured to be driven from any Boolean
register within Nuvation Energy BMS.

7.7.2. General Purpose Digital Outputs

The most commonly used General Purpose Digital Output functions are:
▪
Charge current disable: A control signal that is asserted when charging should be disabled
▪
Discharge current disable: A control signal that is asserted when discharging should be
disabled
▪
Fault state: A signal that is asserted when faults are present within the system
▪
Trigger state: A trigger signal for external devices that is asserted when a specific trigger within
the system is tripped
General Purpose Digital Output functions are assigned through the following configuration registers.
The index n is the zero-based index of the General Purpose Digital Output hardware pin.
sc_gpo[n].address_enabled
▪
Set this to 1 to enable the function specified in sc_gpo[n].address
sc_gpo[n].inverted
▪
When set to 0, GPO output switch is closed when assigned function value is 0
▪
When set to 1, GPO output switch is closed when assigned function value is 1
