Patent ID: 8522607

Claim:
A method for checking an adjustment of a plurality of actuators driven by a common drive in different mass flow channels, comprising: adjusting the actuators between a first limit stop and a second limit stop in the particular mass flow channel; bringing the actuators by the common drive to the first limit stop; ascertaining a first value of a variable that is characteristic of a position of the common drive of the actuators when the first limit stop is reached; bringing the actuators by the common drive to the second limit stop; ascertaining a second value of the variable that is characteristic of the position of the common drive of the actuators when the second limit stop is reached; determining a difference between the first value and the second value; comparing the difference in terms of absolute value to at least one predefined threshold value; and recognizing an error in the adjustment of the actuators in the mass flow channels when the absolute value of the difference deviates unacceptably from at least one predefined threshold value.
