When the passenger gets into the car after stopping at the floor and opening the door and the load of the car exceeds 110% of the rated load, switch 3b opens, so the circuit of P-3b-4-N opens, The overpass detection relay 4 is de-energized, a buzzer (not shown) is sounded, the passenger who boarded last is lowered, and a circuit of P-4b-5a-6-N is formed.
The car call priority relay 6 is energized, and P-6a1-5a-6
The car call priority relay 6 is self-held by the -N circuit.
Next, when a buzzer (not shown) sounds, the passenger gets out of the car, reaches 70% of the rated load, the car starts running, and the car call on the 3rd floor and the ascending hall call on the 2nd floor are registered. If the car is in the deceleration position of the second floor hall when the car is rising, the normally open contact S2U closes, and normally P-

The deceleration command relay 9 is energized in the a-9-N circuit to start deceleration so as to stop at the second floor, but the car call priority relay 6 is energized and the normally closed contact 6b3 opens. Therefore, the deceleration command relay 9 is not energized, and the car does not respond to the ascending landing call for the second floor, and runs to the third floor. Also,
At the deceleration position of the third floor hall, the normally open contact S3U closes, and P-7a-S3U-83b1-53a1-8a-9.
-N circuit is formed and deceleration command relay 9 is energized.
Stop to the floor.
