Question Title

1. The soft starter continuously monitors its own temperature so that it only operates when the temperature is acceptable. (Required.)

True

False

Question Title

2. In the video concerning the monitoring of an ADXL soft starter via Xpress software, which communication accessory was used? (Required.)

EXC1042

CX01

EXCRDU1

CX02

Question Title

3. Soft starters are devices that allow gradual start of electric motors, preventing a series of mechanical and electrical problems. Direct starts (DOL) in fact often cause: (Required.)

high initial current absorption that can cause voltage drops on the power supply network

stresses that reduce the useful life of the motor and the system

Question Title

4. When switched on for the first time, the ADXL soft starter shows a quick guided configuration autosetup with only 6 parameters: language, nominal current, network frequency, cosphi, type of application and duty level.

False

True

Question Title

5. With the ADXL soft starter the motor can be started with different types of starting ramps

current ramp, frequency ramp, torque ramp

voltage ramp, current ramp, torque ramp

voltage ramp, frequency ramp, torque ramp

Question Title

6. If it is essential to start the motor, regardless of the potential for malfunction, all protections and alarms can be inhibited (including the fire system, for instance). (Required.)

False

True

Question Title

7. Even thought not mandatory, a line contacor upstream the soft starter is strongly suggested for the following purposes. Choose the right ones. (Required.)

Protection of the soft starter thyristors

Safety of the personnel

Disconnect the soft starter from the supply in case of fault

Question Title

8. Soft starters are devices that allow (Required.)

a direct motor starting

a gradual motor starting

Question Title

9. The kick start function is useful (Required.)

in applications with loads that have consistent first friction forces,

in applications where you want to avoid water hammer

Question Title

10. The heart of a soft starter is represented by a group of (Required.)

impedences

bridge rectifiers

zener diodes

thyristors

Question Title

11. The range of soft starters ADXL series reaches up to ...

320 A

250 A

162 A

Question Title

12. What are the purposes/advantages of a soft starter bypass? (Required.)

Reduction of the power dissipation (energy saving) and of the heating

Reduction of the harmonic content
