Question 1 of 10
What is the primary function of a Direct-On-Line (DOL) starter?
A DOL starter connects the motor directly to the power source for starting and stopping.
Question 2 of 10
Which component is NOT typically found in a DOL starter?
VFDs are used for speed control, not in a basic DOL starter.
Question 3 of 10
What is the purpose of the 14-PIN relay in this motor control setup?
The relay acts as a switching device controlled by the control circuit.
Question 4 of 10
Which type of push-button is used for starting the motor in the control circuit?
The start button must be NO so that when pressed, it completes the circuit and energizes the relay.
Question 5 of 10
What is the function of the holding circuit in this setup?
The holding circuit maintains the energized state of the contactor and, consequently, keeps the motor running after the start button is released.
Question 6 of 10
Which component protects the motor from overcurrent conditions?
The overload relay is designed to trip and disconnect the motor if it draws excessive current, protecting it from damage.
Question 7 of 10
What voltage is typically used for the three-phase power supply in this example?
The article states the three-phase supply is 415V AC.
Question 8 of 10
Which terminals of the DOL starter are connected to the three-phase motor?
U1, V1, and W1 are the motor's terminal connections.
Question 9 of 10
What type of wire is connected from the 2P-MCB to the control circuit?
The Phase (Line) wire is used to supply power to the control circuit.
Question 10 of 10
What is the purpose of grounding the motor and control circuit?
Proper grounding is a crucial safety measure to prevent electrical hazards.
