3. General description
The devices are suitable for an operation of 3-phase motors in star or delta connection.
In the case of the soft starters of the VersiStart II type the motor voltage is changed in two phases
(1L1/5L3) by a generalized phase control and power semiconductors. Starting from an adjustable
starting trigger angle the trigger angle is continually reduced. Via the adjusted ramp-up time the
motor voltage increases according to a ramp function until the maximum value is reached. When
the acceleration time is over, the power seminconductors are bypassed by integrated relays and
the motor is directly supplied with power from the mains.
After opening of the start/stop-contact, the trigger angle is continuously increased via a ramp-
function, and, as a result, the motor voltage is decreased. The motor softly decelerates with the
adjusted deceleration time.
Acceleration time, starting voltage and deceleration time can be separately adjusted via potentio-
meters.
Acceleration or deceleration are effected by closing or opening of the contact on the terminals
X5/X6 or X4.
The boost function is switched on by bridging the terminals X6/X7. Thus, at the beginning of the
soft start, an increased starting voltage is applied to the motor for a period of 0,5s.
The power supply to the control electronics is effected via the power section.
4. Usage to the intended purpose
The devices of the VersiStart II-series are electrical equipment that is used in industrial electrical
power installations. They are designed for application in machines, in order to reduce the starting
torque and starting current peaks as well as the tripping torque of drives with three-phase
induction motors.
Typical Applications:
• door and gate drives
• pumps
• ventilators
• conveying systems
• packaging machines
