PURPOSE:To retrieve private power generating capacity necessary to elevators by running an elevator toward a lower reference floor when a total weight of passengers is higher than a balance weight decided by a rated loading amount and running it toward an upper reference floor when it is lower. CONSTITUTION:Circuit source buses P and N, a raising command relay U to command raising operation, a lowering command relay D to command lowering operation, a contact 52G closed when a private power generating source is fed to an elevator, and a contact E opened when a cage arrives at a main lobby or a sky lobby and a door is opened. The magnitude of a total weight of passengers in comparison with a balance weight decided by a rated loading amount is detected, and when the total weight of passengers is heavier than the balance weight, an elevator is run toward a lower reference floor and when it is lighter, the elevator is run toward an upper reference floor. This system retrieves private power generating capacity needed by an elevator during outage. |
