Patent ID: 8573241

Claim:
A method comprising: receiving a control signal for a fluid regulator control system at a field test initiator, wherein the control signal is received at an initial value; altering the initial value of the control signal by directing the control signal to a control signal modifier at the field test initiator upon detecting activation of at least one user-input device of the field test initiator, wherein the initial value changes according to activation of a first switch and a second switch in response to, respectively, a first user input device and a second user input device on the field test initiator to change the initial value of the control signal to a first value and a second value that correspond to, respectively, the first switch and the second switch, wherein the first value is different from the second value; conveying the altered control signal from the field test initiator to the fluid regulator control system; determining whether the initial value of the altered control signal satisfies a first operational criteria and a second operational criteria, wherein the first operational criteria includes whether the altered control signal satisfies a pre-determined value, and wherein the second operational criteria includes a pre-determined range of values; and generating a fluid regulator control signal, wherein, in response to the initial value failing to satisfy the first operational criteria the fluid regulator control signal adjusts a position of a fluid regulator to a safe mode position and latches said fluid regulator control system in the safe mode position to prevent generating of the fluid regulator control signal until initialization of said fluid regulator control system, and wherein, in response to the initial value satisfying the first operational criteria and the second operational criteria, the fluid regulator control signal initiates a fluid regulator testing sequence.
