Sources Range
Notes
Control Source Not Used
N/A
When this is selected, it disables all other
setpoints associated with the input in
question.
Current Charging Stage
N/A
This parameter holds the value of the current
charging state from pre-charge (1) to float
(4). If the charging is disabled, this value is 0
Current Feedback Measured
N/A
Measurement of current drawn by battery at
any point during its charging profile
Power Supply Measured
N/A
Monitors the power supply voltage (VIN
connector pinout)
Battery Voltage Measured
N/A
Monitors the battery voltage (BATT
connector pinout)
Thermistor Input Measured
N/A
Monitors the resistive value of a NTC (or
PTC) thermistor input.
Received CAN J1939 Message
1 to 8
The CAN Receive Messages each have a
unique default assigned to them as outlined
in Section 1.11
Diagnostic Trouble Code (Rxd)
1 to 4
Will only be valid if the corresponding DTC
has a non-zero SPN
Processor Temperature Measured
N/A
Input to Over Temperature Diagnostics
Can be mapped to a CAN Txd
Lookup Table Function Block
1 to 6
User must enable the function block, as it is
disabled by default
Control Constant Data
1 to 10
1 = Always FALSE, 2 = Always TRUE,
3 to 10 = User Selectable
Processor Temperature Measured
N/A
Input to Over Temperature Diagnostics
Can be mapped to a CAN Txd

N/A
When this is selected, it disables all other
setpoints associated with the input in
question.
Battery Charge Disabled
N/A
Charging operation has been halted by
firmware due to an error (VPS, VBatt,
overcurrent errors, etc)
Battery Voltage Fault
N/A
Battery voltage fault event will command
LED
Power Supply Fault
N/A
Power Supply fault event will command the
LED
Processor Temperature Fault
N/A
Processor Temperature fault event will
command the LED
