Background:
This lift is situated in a building belonging to an educational institution located in the canton of Aargau, Switzerland. The building was originally constructed as a warehouse/storage building in the 1950s. In the 1990s it was fully renovated and made suitable for its present use. In the context of this renovation the core of the building was fully reconstructed so that it now contains technical rooms, sanitary installation and this service lift. There also is a documentation on the other lift in this building, which can be found here:    • 90s Thyssen Lift in old GLASS SHAFT i...  
Since that lift is smaller and slower than the one presented in this video here, it could not handle the large amount of people frequenting the building every day. The service lift is crucial for moving the large quantities of people around the building as well as for the transportation of equipment that would not fit into the smaller lift.

The lift:
This lift is extraordinary in many ways. It has a large capacity for not being a dedicated freight lift. It travels at a speed of 1.6m/s, which is a rather fast speed for 25 meters - especially for such a large lift.
The most outstanding feature of this lift however is that it runs on the Miconic V logic. The Miconic V was Schindler's high-rise controller in the 1990s and was generally used for larger groups of lifts in tall office buildings. Finding such a controller on a single lift is very rare, especially as the task at hand could also be done by the cheaper and more common Miconic B controller. The latter supports speeds of up to 1.75m/s, which would be fast enough for this lift. Furthermore the combination of S-series fixtures and Miconic V controller is again extremely uncommon.

The controller:
The Miconic V was Schindler's high-rise controller of the 80s and 90s. It was the successor of the Aconic controller, which was very complex and built out of single transistors. The Mic V finally brought the age of microprocessors to Schindler's high-rise controllers. The low-rise equivalent, the Miconic B, was already on the market. The Mic V however had some great advantages over the Mic B: Firstly it was fully parameterizeable, all settings can be changed through the screen and keyboard. In order to change any parameters on the Mic B, the EPROM would have to be manually reprogrammed.
The Mic V has an intelligent and highly accurate positioning system, working with light beams and an incremental encoder mounted on the overspeed governor. The position of the car is always known and immune to rope slip. The Mic B however uses bistable magnets and has no information on the car position between the magnets.
The Mic V has an intelligent traffic management system that can distinguish up-peaks, down-peaks and interfloor-phases. The load of the lift car also feeds into the algorithm, making full lift cars ignore floor calls.
The Mic V was available with two main drive options: The Dynatron MV and the Transitronic.
- The Transitronic is a DC-drive for high-speed gearless DC motors up to 8m/s. There were several variants of the Transitronic including ones with motor-generator-assembly for DC generations and newer ones using a static inverter.
- The Dynatron MV is a Phase-fired controller (PFC) which drives a special motor equipped with an additional eddy current brake. The Dynatron MV is used in this lift here and is suitable for speeds up to 2.5m/s.
Note that this is only a very small fraction of information on the Miconic V and that a full in-depth description would never fit in here.
