Safe System LES03 / SGT02

Electronic overspeed governor
In combination with the sensor Ants LES03, the SGT02 can replace traditional mechanical overspeed governors.

Control-independent
The electromechanical safety gear is triggered independently of the control system, making the system ideal for modernization projects.

Absolute position detection
In addition to the function as electronic speed limiter, the 100% slip-free recorded position data can optionally be transmitted to the control via CANopen Lift. CAN/SSI/RS485 are also possible on request.

Overspeed
When the Ants LES03 sensor detects an overspeed, the SGT02 triggers the electromechanical safety gear. The system can be combined with different safety gears available on the market.

Condition monitoring and reset
The SGT02 also takes over the monitoring and resetting of the respective safety gear. In addition to direct evaluation, the status information can also be processed by a control system if required.

Establishment of refuge spaces (Shield-Mode) 
In addition to safety for assembly personnel in accordance with the requirements of EN 81-21, the Shield mode of the SGT02 sets new standards for the safety of installation, service and maintenance personnel. Even during scaffold-free assembly, the system independently forms position- and speed-dependent refuge spaces.

Self learning system
Due to the respective highest and lowest approached position in the elevator shaft, refuge spaces are automatically produced. 

Easiest validation      
From plant approval to annual inspection - the reduced complexity simplifies validation processes and guarantees the highest safety standards.

Visual and audible status indication      
All safety-relevant parameters can be checked quickly. The simple menu navigation as well as visual and acoustic assistance will inspire not only installers but also approved inspection agencies (ZÜS).
