Abstract

PURPOSE: To prevent the long-time rest of elevator, by operating a restoring unit to immediately run the elevator after an earthquake has been detected by only an earthquake detector and the elevator has stopped.
CONSTITUTION: When an earthquake occurs and an earthquake sensitive relay is energized, contacts 5a, 5b are closed and a contact 5c is opened. Thereby, a safety confirmation relay 4 is de-energized and the elevator immediately stops running. At that time, a derailment holding relay 2 remains de-energized and therefore a contact 2b remains closed. Then, an operation restoring display light 8 is turned on to indicate that the operation of the restoring unit is effective. When the restoring unit 6 is operated, a restoring unit detection relay 7 is energized through a circuit comprising a plus terminal, the contact 5b, the restoring unit 6, the relay 7 and a minus terminal, a contact 7a is closed and a contact 7b is opened. Thereby, the safety confirmation relay 4 is energized and the elevator resumes operating.
