ABSTRACT:
A method for operating a rotary machine is provided. The rotary machine includes a stationary member and a rotatable member wherein the rotatable member is configured to rotate at least partially within the stationary member. The method includes determining an off-normal operating condition of the rotary machine facilitating undesirable contact between the rotatable member and the stationary member, monitoring a parameter associated with the off-normal operating condition, and preventing operation of the rotary machine while the monitored parameter is within a predetermined range.
