TROUBLESHOOTING
FAULT CODE REGISTER
Following a fault condition, the controller runs a section of code to determine the cause of the fault. The
display will show a fault type message, its corresponding fault code value, and the fault code register value.
If a fault occurs, record these three values and contact the factory for assistance. The display will only
show the first error condition encountered but the fault code register value encodes the status of all fault
conditions. The controller will also check the SRAM memory for corrupt variables and allow the operator
to restore factory default settings if a problem is detected. The controller memory is verified at power-up
and during fault conditions. The controller continuously monitors the following conditions:
