New Indian Component Manufacturers’ Association
In India, the Elevator & Escalator Component Manufacturers' Association of India (EECMAI) was founded in September.
The Cedes iDiscovery adopts safety-relevant functions of a lift according EN 81-20 up to SIL3. The system is EU type examined by TÜV Rheinland. Later this year Cedes will launch an iDiscovery with enhanced inspection functionality.
iDiscovery, in conjunction with Cedes’ APS, is a PESSRAL system featuring a pure electronic overspeed governor to trip an electrically activated safety gear. According to Cedes, the system eliminates the need for many individual systems and components currently required by a conventional lift. In combination, the APS and iDiscovery significantly reduce the cost and complexity of the lift as well as installation and maintenance time.
The iDiscovery monitors position and velocity of the lift car as well as the status of the car doors, landing doors, and additional status signals of the lift such as emergency operation and inspection control switches.
In the case of an unsafe condition, iDiscovery opens the safety chain. Further, iDiscovery provides two additional output contacts, which trigger an auxiliary braking device and an electrically activated safety gear.
Within this year, Cedes will launch an iDiscovery with enhanced inspection functionality. The additional functionality will safeguard the safety spaces for lifts with reduced headroom or pit (EN 81-21).
In conjunction with an electrically activated safety gear, the pre triggered-stopping devices and movable stops currently used can be replaced. So the costs can be drastically reduced again, emphasized by Cedes.
iDiscovery is configured in the field on the job site. Safe configuration of the safety relevant parameters, rated speed and final limits, is performed with configuration clips that are mounted with the APS code tape. The safety-relevant configuration can also be changed in the field.
No additional programming tool or pre generated parameter sets are required - configuration with configuration clips is free of hassle, according to Cedes. The on-site configuration makes it obsolete to manage and stock devices with different preconfigured rated speeds. This allows for great flexibility and simplicity during the entire lifecycle at every stage – planning, installation and operation.
The use of the configuration clips in combination with the floor indicator clips allows a fully automated teach process and leads to an efficient and straightforward configuration and teaching process. The lift is moved with inspection speed from bottom to top. Rated speed, bottom floor, top floor, final limits and floor positions are read from configuration clips and floor indicator clips. This process is fast and simple, Cedes emphasised.
iDiscovery is engineered in a modular way. This allows for a maximum level of flexibility when choosing the functionality that matches the different lift lines. The device is available with or without the interface module, which triggers the electrically activated safety gear.
Given that the iDiscovery is independent from the APS mounting location and the ability of APS to transmit data up to 1500 meters, iDiscovery can be installed wherever it is most suitable – for example , in the lift controller in the machine room, the landing door frame or directly onto the car.
