DOOR SWITCH TROUBLE DETECTOR AND SWING DOOR WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a switch trouble detector for an automatic swing door at a low cost having high performance and high reliability.

SOLUTION: Combinations of different switch outputs are set every section so that a door open/close range is partitioned into a plurality of sections and the sections are specified by combinations of the on/off states of a plurality of switches 116, 117 and 71-73 corresponding to each section. Troubles of the switches are decided when the on/off states detected by the switches correspond to the combinations excepting combinations of the switch outputs stored by a switch-state storage means and when changes of the on/off states of the plurality of switches are converted into the combinations different from specified orders in the storage means in the switch-state storage means in which orders of the changes of the combinations of the on/off states of the switches with door opening and closing are stored previously.
