TIP The fault display will remain active as long as control power is applied. If
control power is cycled, the fault will be cleared, the controller will re-initialize,
and the display will show a status of “Stopped”.
TIP You can hit ESC to get to another programming/diagnostic list, but the SMC
Flex will still be in a faulted state.
IMPORTANT Resetting a fault will not correct the cause of the fault condition. Corrective
action must be taken before resetting the fault.
