Abstract
PURPOSE: To provide an apparatus for detecting trouble of elevator, in which there is provided a means for controlling the output of a speed detector according to the cage position, and a trouble detector is operated by the controlled output, whereby structure of the apparatus can be made simple and reliable, and at the same time, it is enabled to detect trouble with ease when some trouble is caused with speed instructing means.
CONSTITUTION: Operation speed controlling resistance 32 and trouble detector 33 are connected in series to the output circuit of speed detector 7, and resistance value of said resistance 32 is controlled by normally closed contacts 21bW28b of speed notch relays 21W28 and normally closed contact 20b of operation relay 20 indicating the cage position. Thus, in accordance with the above arramgement, resistance value of said resistance 32 is changed with the position of cage 10, so that it can be monitored whether or not elevator speed is controlled at a required value corresponding to each position of cage 10.
