3. General description
The electronic braking devices of the VersiBrake LT-type enable non-wearing braking of three-
phase and single-phase asynchronous motors. The braking devices are used for drives that, due
to safety and functional reasons, have to be reliably slowed down. Braking is initiated when the
connected and normally closed contact of the motor contactor is reclosed. After a time lapse
adjusted with the potentiometer „t“, the braking current adjusted with „I“ is switched off.
The operational status and any possible faults are indicated via LEDs and a flashing mode.
Special features
• controlled by microcontroller
• wear-resistant and maintenance-free
• for three-phase asynchronous motors
• for mono-phase motors
• retrofitting into existing plants possible
• integrated braking contactor
• automatic remanence time optimization
• integrated overload monitoring
• braking current contro
• Braking interrupt possible
• Restart possible 1,2s after braking interrupt
• Wide adjustment range of the braking time (0...30s)
• Suitable as a replacement for braking devices of the types BR and BR-L
4. Usage to the intended purpose
The devices of the VersiBrake…-LT-series are electrical equipment that is used in industrial
electrical power installations. They are designed for application in machines, in order to slow
down rotating masses on drives with three-phase a.c. motors.
Typical applications
• sawing machines
• centrifuges
• wood working machines
• conveying systems
• textile machines
