What are the three basic sections of a motor control schematic diagram?
Stop circuit
start circuit and
holding circuit
Can a stop circuit contain the normally closed contacts of an overload device?
Yes. In this position they can be energized the contactor coil when an overload occurs
True or false? Contacts connected in the stop circuit affect both the starting and stopping of the motor.
True
True or false? Contacts connected in the start circuit affect starting and running of the motor.
False. affect only the starting of the motor
True or false? Contacts connected in the holding circuit affect running of the motor
True
How are multiple stop buttons connected with respect to each other? N/C OR N/O
Normally closed and connected in series
