A method of operating an automatic door installation with door sensor equipment including a door sensor 100, which may be an optical sensor with emitters and receivers, comprises evaluating an operating condition of the door installation, determining whether the operating condition lies within a standard operating range and operating the automatic door installation in a contingency mode when the operating condition lies outside the range. The door installation being operable in a standard mode, in which the door sensor equipment conducts an obstacle check to determine whether an obstacle is present according to a first procedure, and a contingency mode, in which the door sensor equipment conducts an obstacle check according to a different second procedure. The operating condition may be the temperature, level of noise, level of vibration, voltage of a power supply, current consumption, level of optical occlusion, functioning or non-functioning state of a component or performance of a component. The second check may comprise repeating a step multiple times. A property may vary in the second check from the first check; the property may be the carrier frequency, light intensity, frequency hopping property, time period, data format or phase. There may be an auxiliary sensor 130 only used in the second check. The contingency mode may comprise reducing the door closing speed.
