It consists of the following units:  The machine room unit (ElevationBase) which handles safety and local automation in controlling lift motion and car door operation. In addition it controls system back-up and car evacuation operations in the absence of line power. Օ The car unit (ElevationCar) which processes and communicates all car signals and transport demands to the ElevationBase unit and controls car door, fan and light activity.  The floor unit (ElevationFloor) which processes and communicates all floor level signals and transport demands to the ElevationBase unit and controls the floor level indication and call activity. All system inputs are fully protected against overvoltages and reverse polarity connection. Each input signal is processed by a noise rejecting DSP filter and its logic state (positive/negative logic) is specified at the unit operation parameters. All 24 VDC outputs are protected against overvoltages, reverse polarity connection, reverse load current and inductive spikes. r.1 Dec11 Copyright © 2011.
