260kW Faults and Warnings
Fault Variables
The 260kW firmware will utilize one, 16-bit variable (fault) to indicate a fault condition.
Each bit in this fault variable represents the fault type or category. The bit assignments
and specific fault variables for the fault categories are as follows:
Description
Bit
Nbr.
Hex
