PURPOSE: To improve workability by a method wherein a power supply is tuned on after the completion of a power opening-closing door, the door is opened and closed at low speed and a door stroke is measured and stored while the door is freely opened and closed normally on the basis of the stored values. CONSTITUTION: After a door is installed a builder turns a power supply on and drives a motor M at low speed, and measures the opening-closing stroke value of the door. The opening-closing operation of the door 5 is observed at that time, a length-measuring data-set switch 31 is turned on at the time of correct opening-closing operation, and a door stroke value counted by a counter circuit 23 is stored in a non-volatile RAM 25. When the power supply is tuned on under the state, in which the switch 31 is turned off, a command circuit 24 decides whether or not the door stroke value is stored in the RAM 25. When the door stroke value is stored, normal door opening-closing operation is conducted by a human-body detecting signal R1 on the basis of the door stroke value stored in the RAM 25 without door low-speed opening-closing operation for measuring length. Accordingly, even when a building is completed after the completion of the door, the door can be opened and closed by the hand of the builder. |
