Page 4: Safety Notes
VB 230/400-25 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. -
Page 5: General Description
VB 230/400-25 General description The electronic braking devices of the VersiBrake type enable a non-wearing braking of three- phase and a.c. asynchronous motors. The braking devices are used for drives that due to safety and functional reasons have to be reliably slowed down. After the motor has come to a standstill, an integrated standstill detection switches the braking current off. -

Page 8: Led Indicators
VB 230/400-25 Approx. 1.5s after a motor standstill has been detected, the integrated standstill detection function switches the braking current off. If during the maximum braking time (15s in the case of standard devices) no motor standstill is detected, the fault signaling contact on the terminals X7, X8 (alarm) opens. When restarting the motor, the signaling contact will be reset. -

VB 230/400-25 12.3 Parameter settings Sequence of commissioning: 1. Disconnect the plant from the supply mains. 2. Connect the current measuring instrument between the braking device, terminal „2T1“, and the motor terminal „U“. 3. Turn the potentiometer "I" to a position in the first third of the adjustment range (factory setting) (please see chapter 7 on page 8). -
Page 16: Dimensioning Rules
VB 230/400-25 13. Dimensioning rules 13.1 Dimensioning of braking contactors The braking contactor is switched on or off via a control contact of the braking device (no-load switching). When selecting the braking contactor, it must be ensured that the contacts are able to carry the maximally occuring braking current (nominal/rated device current). - Page 17 Note 1: 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. If the value of the fuse or cutoff-I²t-value is selected too small, it may happen Note 2: that the semiconductor fuse reacts during braking.
