VERSO

VERSO System: A comprehensive elevator control solution

A high-performance elevator control system goes beyond just a control cabinet; it integrates floor selection, management of car components, signaling, communication, and emergency systems into a cohesive architecture. The VERSO system embodies this approach with an integrated product range, designed and manufactured in France by a certified electronics engineering firm.

The concept: ready-to-install solutions—featuring fast delivery and quick assembly—designed for elevator professionals for use in both new installations and modernization projects.

Components of the VERSO system

At the heart of the system, the cabinet incorporates a variable-frequency drive, a 3.5-inch touchscreen, a multifunction electronic board, and a built-in backup battery. It is available for both machine-room and machine-room-less configurations (with the variable-frequency drive integrated into the cabinet or installed within the elevator shaft).

These optoelectronic safety sensors handle floor selection, overspeed management, and UCM (Unintended Car Movement) detection. The COPTER 3 OSG version also supports the management of reduced clearances—as per the EN 81-21 standard—via an electric safety gear, in conjunction with the STB board.

The VERSO cab-roof unit manages cab components and incorporates siren and buzzer functions. SIMÉO, a multiplexing unit, handles control and signaling for the cab’s button panel.

The landing bus system relies on a 3-wire harness: the bus interface and the audible signal (beeper) are integrated within the dimensions of the push-button (36.5 mm in diameter), while the sound level and button assignment are configured from the control cabinet. A single trailing cable (containing 20 wires and 4 voice-communication quads) connects the entire assembly.

This connectivity unit enables remote management of equipment: over 200 accessible parameters, real-time alerts, diagnostics, and remote interventions.

In the event of a power failure, the RNS moves the elevator car to the nearest floor and opens the doors. It operates using the VERSO unit’s built-in battery, regardless of frequency variations (supporting brakes from 48 to 200 VDC and motors up to 12 kW / 40 A, whether synchronous or asynchronous).

A compliant and certified system

  • Compliant with EN 81-20 and EN 81-21 (reduced clearances), EN 81-70 (integrated voice synthesis), and includes built-in UCM (Unintended Car Movement) protection
  • Electronic safety chain rated SIL 3 (IEC 61508)
  • Low power consumption: energy-saving feature that cuts the power usage of the control cabinet and its peripherals by half
  • Simplified updates via SD card; PC-compatible
  • Manufactured in France; ISO 9001 and ISO 14001 certified

Why choose an integrated solution?

Components designed to work together reduce the risk of incompatibility, simplify wiring, and centralize configuration settings via the control cabinet’s display. Time savings during installation and the traceability provided by a single manufacturer offer a tangible advantage on the job site.

Conclusion

The VERSO system offers a comprehensive elevator control architecture—from the control cabinet and optoelectronic positioning to remote connectivity and emergency backup systems. This overall coherence streamlines commissioning and maintenance while ensuring full compliance with EN 81-20 and EN 81-21 standards.

FAQ

What does the VERSO system include?

It includes the control cabinet, COPTER 3 / COPTER 3 OSG sensors, the car-top unit, the SIMÉO multiplexing unit, the landing bus, the VERSO Connect unit, and the emergency floor return device (RNS).

Is the VERSO system suitable for modernization?

Yes, the product range is designed for both new installations and modernization projects, whether or not a machine room is present.

What is the maximum speed supported?

The system supports car speeds of up to 1.6 m/s with a stopping accuracy of 1.2 mm.

Does the system comply with the EN 81-21 standard?

Yes, it provides for reduced safety spaces through the use of an overspeed governor and bi-directional safety gear, top and bottom buffers, or an electric safety gear system combined with the COPTER 3 OSG and an STB board.
