Part 4: Contactors and motor starters including short circuit and overload protection devices. Part 5: Control circuit devices and switching elements. Part 6: Multiple function equipment such as that used for automatic emergency power switching. Part 7: Ancillary equipment such as terminal blocks used to connect copper conductors.

Figure 4 – An industrial control cabinet with wire runs, terminal strip, buttons on PLC panel front, etc. When including a PLC in the ladder diagram still remains. But, it does tend to become more complex. Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.

Wiring diagrams help technicians to see how the controls are wired to the system. Many people can read and understand schematics known as label or line diagrams. This type of diagram is like taking a photograph of the parts and wires all connected up. These diagrams show the actual location of parts, color of wires, and how they are connected.

Wiring diagrams. Wiring diagrams show the connections to the controller. Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller. Basic wiring for motor control – Technical data

Electric Motor Controls, G. Rockis, 2001 Wiring Diagrams Wiring (connection) diagram – a diagram that shows the connection of an installation or its component devices or parts. Wiring diagrams show, as closely as possible, the actual location of each component in a circuit, including the control circuit and the power circuit.

4 thoughts on “ How to Read Industrial Control System Wiring Diagrams ” Marshall June 1, 2011 at 4:01 am “First of all, most modern (North American)…” And for EU based equipment IEC 61346 the standard to read up on. Personally I find both systems have there pros and cons.

Because every type of machine has unique requirements for wiring methods, operator safety depends on your understanding the differences between rules in the NEC and methods outlined in NFPA 79.Every type of machine has unique requirements when it comes to operator safety. From an electrical standpoint, industrial machine equipment and tools - from drill presses to multi-motored automatic machines

These diagrams are current at the time of publication, check the wiring diagram supplied with the motor. *NOTE: Refer to the motor manufacturer’s data on the motor for wiring diagrams on standard frame Ex e, Ex d etc. motors. Inst Maint & Wiring.qxd 5/03/2008 10:02 AM Page 6

Figure 6 is a diagram for a 480/276-volt, three-phase, four-wire system. This system serves hotels, shopping centers, etc. Transformers are used to get 120-volt single-phase circuits. Figure 7. Figure 7 shows the system used for large industrial plants where most of the load consists of motors. It is a 480-volt delta three-phase system.
