| | | TECHNICAL FEATURES | | |
| | | |
| | | Operation system • Selective collective operation The momentary pressing on one or more car buttons shall send the car to the designated landings in the order in which the landings are reached by the car, irrespective of the sequence in which the buttons are pressed. During this operation, the car shall answer calls from the landings which are in the prevailing direction of travel, and each call shall be canceled when answered. | | |
| | | |
| | | Attendant operation The operating mode of an elevator can be changed from the normal full - automatic operation to the attendant service by an attendant switch, when required. The switch is located on the car operating architectural panel with a sliding cover. | | |
| | | |
| | | Service functions • Safety drive operation When a car stops between floors due to mechanical malfunction, the car descends to the nearest Door below. | | |
| | | |
| | | Anti - nuisance operation In case of substantial difference between the number of calls registered on the car operating panel and actual load in the elevator, the elevator prevents unnecessary operation by cancelling all registered calls when it arrives at the nearest floor. | | |
| | | |
| | | Door open and close times are automatically adjusted depending on whether the call is a hall call or a car call to increase the operating efficiency. | | |
| | | |
| | | Car door safety edge Extending the full height of the car door, this device causes the modern doors to return to the fully open position, should the door encounter a person or obstacle while closing. | | |
| | | |
| | | Micro levelling An automatic two - way levelling device is provided to maintain the elevator car level with the landing, regardless of elevator load or direction travel. | | |
| | | |
| | | Car illumination and fan are turned off automatically in case there is no hall call or car call, saving energy. | | |
| | | |
| | | Detection of jammed hall button and exclusion from operation service If a hall button is jammed mechanically, the hall call will be automatically bypassed after being served once, until the problem is resolved. | | |
