PURPOSE:To rapidly return the operation of an elevator to the normal operation thereof when condensate from a cooling unit in an elevator becomes full so that an elevator cage ascends up to the uppermost floor where the condensate is discharged through a hose. CONSTITUTION:When a full water detecting switch 1 is closed, a drain operation instruction relay 2 is energized so as to close a contact 2a. Accordingly, an ascent relay 5 is energized so that an elevator cage ascends up to uppermost floor where condensate is discharged. When the cargo reaches the uppermost stage, a contact 6b is closed so as to energize a full water operation interruption, detection relay 2 and a contact 12a is opened while an ascent relay 5 is deenergized. Accordingly, if no call is issued, the draining is continued, but if a call is issued, the cargo is started. |
