To immediately check whether or not an escalator facility is damaged when the escalator facility is automatically stopped due to an earthquake, etc., and to recover the automatically stopped escalator facility when the escalator facility is not damaged, to greatly improve users' convenience.
When the escalator facility 2 is automatically stopped due to an earthquake, etc., test operation of the escalator facility 2 is performed, and whether or not a deviation between an electric power consumption value obtained during the test operation and an electric power consumption value at normal time stored in a normal time measurement value saving means 41 of a central monitoring control device 5 is below a preset threshold value, is checked. When the deviation is below the threshold value, the escalator facility 2 is determined not damaged and restarted.
