How to control the direction of a DC motor?
To control the direction of the spin of DC motor, without interchanging the leads, you can use a circuit called an H-Bridge. An H-bridge is an electronic circuit that can drive the motor in both directions. H-bridges are used in many different applications.
What does open circuit mean in control circuit?
Open Circuit Faults in the Control Circuit. Open circuit faults – An open circuit fault is any fault that stops the operation of a machine due to an open wire or component.
Can a short circuit be an open circuit?
Accidental open circuits are usually harmless but can be the source of much frustration when you’re trying to figure out why your circuit isn’t working the way you think it should. Short circuits are another matter entirely.
How to troubleshoot an open circuit fault in the control?
The fault could also be many different types, such as, open circuit fault, short circuit fault or a ground fault. This general troubleshooting procedure is designed to start in the middle of the problem area and give us the best idea which direction to go.

How to tell if a control circuit fuse is open?
You should check the voltage on X1 at the top of the control circuit fuse and X2 at the top of the neutral link. If the correct voltage is present, continue to Step 6. If the correct voltage is not present, then X2 wire is open from the top of the neutral link to the terminal on the secondary of the transformer.
Where is the control transformer in the circuit?
The control transformer is a good place to start since it is in the middle of the circuit and is part of the power and control circuits. The first three steps of this procedure will be the same for all faults and the rest will be completed throughout this chapter in more than one procedure.
