<p>The control of a turnstile operation having a blocking element (13) is characterized in that during stepping a blocking means (14) from blocking position thereof into the position in which the passage of persons is permitted, a next blocking means (14) is moved in the direction of rotation into the blocking position and in case of events disturbing the current operation at least the blocking means (14) being situated in blocking position is moved from its position blocking the passage of persons into its inactive position enabling uncontrolled passage of persons. After termination of such disturbing event this blocking means (14) is automatically set in its usual operating position and in this position it is removably secured. The blocking element (13) is subjected to the action of an electric inching motor so that after termination of the disturbing event enabling mobility of at least one blocking means (14) being situated in blocking position to inactive position thereof, resetting forces causing with respect to the blocking element (13) axis of rotation (15) the reset of the blocking means (14) being in its inactive position to its current operating position, will act on the blocking means (14) being in its inactive position by stepping thereof by at least one step.</p> |
