Page 4: Safety Notes
VB230/400-6/25/30LT Safety notes The described devices are electrical equipment for use in industrial electrical power installations. An impermissible removal of the covers during operation can cause serious damage to your health, since these devices contain live parts with high voltages. Adjustment work may only be performed by trained staff observing the safety regulations. -
Page 5: General Description
VB230/400-6/25/30LT 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. -

The motor can be started. A starting logic makes sure that, when switching the plant on with the master switch while the motor is still switched off, braking is not initiated. -

VB230/400-6/25/30LT For the braking currents applicable to the respective braking times please refer to the table under point 7. By using an integrated monitoring function, the device protects itself against overloading caused by a too high braking frequency. For commissioning or setting-up purposes, 5 braking operations in direct succession are allowed. -

Braking interrupt: With the input X3, X4, a braking interrupt can be effected. For this purpose, another normally closed contact has to be connected in series before the normally closed contact of the motor contactor. -

This contact is to be looped into the control contact, common circuit of the motor contactor. Therefore, the motor contact on X5) cannot be started during braking. -
Page 11: Potentiometers
VB230/400-6/25/30LT Potentiometers With the potentiometers it is possible to adjust the following parameters. „I“ Adjusting the braking current. The braking current can be adjusted in the range from approx. 10% - 100% of the rated device current. The adjustment is roughly linear. Caution! If braking times exceeding 20s are adjusted, the rated device current decreases according to the diagram on page 9. -

Page 14: Parameter Settings
VB230/400-6/25/30LT 11.3 Parameter settings Sequence of steps during commissioning: 1. Disconnect the plant/system from the supply mains. 2. Adjust the requested braking current with the potentiometer „I“ (approx. 2 times the rated motor current). Since the potentiometer reacts roughly linear, it is possible to infer the braking current from the potentiometer setting. -
Page 15: Possible Fault Indications During Commissioning
VB230/400-6/25/30LT Note: If, after a braking operation, the „Ready“ LED flashes 2x (braking current was not reached), it may be possible that the value adjusted for the braking time was too small (0...1,5s). The braking time is then too short to build up a flow of current in the motor. - Page 16 VB230/400-6/25/30LT Continuance Flashing 3x Braking device is The specified max. braking Reduce braking current or overloaded. frequency is exceeded. braking frequency.

All data sheets and commissioning instructions are avaialble on our homepage at www.peter-electronic.com. 12.1 Dimensioning of braking contactors The braking contactor is switched on or off via a control contact of the braking device (no-load switching). - Page 18 On the basis of the recommended I²t-value, braking current, and possibly the c.d.f., the fuse supplier is able to select a suitable type. Due to the great variety of producers, sizes, and types, PETER electronic does not recommend any particular fuses.
