Industrial control panels consist of power circuits or control circuits (or both) which provide signals that direct the performance of machinery or equipment. Industrial control panels don’t include the main power, nor do they include the controlled equipment; rather, the panel is mounted on a back panel (or subpanel) or in an enclosure, depending on the application. Industrial control panel design begins with weighing design requirements and specifications and preparing schematics, but the design process can be quite complex in order to ensure that all applicable regulatory standards and safety requirements are met. We’ve created this guide to provide an overview of the key design considerations applicable to industrial control panel design, including schematics, relevant regulatory standards, and design considerations relating to every facet of effective control panel design for industrial equipment and machinery. Included in this guide:. Industrial Control Panel Design – Schematics Control panel design for industrial equipment and machinery is an important undertaking, resulting in an interface designed to control a machine or process. It’s not a simple matter of selecting an appropriate enclosure and a back panel that houses the electrical hardware. So, the proper hardware must be mounted on a back panel and properly wired and integrated into the machine – any improper configuration can result in malfunctioning machinery, but it’s also likely to pose an unnecessary risk to operators. The process should always begin with an evaluation of the specifications, requirements, and regulatory standards.
After these considerations are evaluated, to outline the specific configuration of wiring, circuits, controls, and every other aspect of the final control panel. Good design addresses both the electrical and physical requirements. These:. I/O diagram.
Control cabinet and back panel layouts. Because there are so many elements in a, a table of contents is also recommended.
The schematic is the foundation for the subsequent development of an industrial control panel. Regulatory Standards Related to Industrial Control Panel Design Despite many Code cycles, many industrial control panels are still not compliant with the regulatory standards which are accepted industry-wide.
Compliance, however, is critical for ensuring minimal safety risks associated with installing and operating industrial equipment and machinery. Below is an overview of the most prominent regulations applicable to the design, manufacture, and installation of industrial control panels. Like all regulatory standards, industrial control panel standards are subject to change over time, and in fact, one of the most relevant standards, UL 508, has recently been phased out and replaced by an updated, harmonized international standard. Because of the changing nature of regulatory standards, it’s important to stay up-to-date on current requirements.
NEC The (NEC), or NFPA 70, is a widely-accepted standard for the safe installation of electrical equipment and wiring. The NEC is adopted by state or by region to standardize the enforcement of safe electrical practices. Covers industrial control panels and applies to panels intended for general use at 600 volts or less, in ordinary locations. Article 409 specifies that industrial control panels must be evaluated and marked for their (SCCR), which is established by evaluating each feeder individually as well as all branch circuits. The smallest kA value is used as the kA value for the panel as a whole.

The kA value must be greater than the kA value of the incoming source in order for the panel to be installed. NFPA 79 (National Fire Protection Association) 79 is a that pertains to wiring standards for industrial machinery. The scope of this standard encompasses electrical and electronic elements of all machinery that operates at or below 600V, including injection molding machines, assembly machinery, machine tools, and material handling machinery, among others, as well as inspection and testing machinery.
NFPA 79 for industrial machinery aimed at protecting operators, equipment, facilities, and work-in-progress from fire and electrical hazards. Relate to control circuits and control functions, operator interface and control devices, location, mounting, and enclosures for control equipment, and other topics relevant to the design of industrial control panels. UL 508 and UL 60947-4-1 was one of the most important standards to recognize for many years, but this standard has recently been phased out and has been replaced. Before January 26, 2012, listed control panels were evaluated to standard UL 60947-4. If a customer specifically requested that a panel be evaluated to UL-508, this was permissible. From January 26, 2012 through January 26, 2017, new industrial control panels were evaluated to UL 60947-4.
However, evaluating revisions to existing control panels to UL-508 was permissible if requested. After January 27, 2017, all listed industrial control panels are required to meet UL 60947-4-1 specifications. The transition is meant to from UL and other entities including the Canadian Standards Association (CSA) and the International Electrotechnical Commission (IEC) in Europe.
It’s worth noting that UL 508 and UL 60947-4-1 are largely the same in a technical sense but do incorporate important national differences in order to harmonize and create an international standard. The primary impacts of the transition relate to how products are to a standard due to differences in voltages used around the world. Industrial voltages in the United States are 480 V at 60Hz, while industrial voltages in Europe are 400 V at 50Hz. The new UL 60947-4 standard “applies to the types of equipment listed in 1.1.1 and 1.1.2 whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c.
Connections and routing tips for wiring industrial control panel (photo credit: powerindustrialcontrols.com) However, there are dozen of tips and advices on how to do this and that, but this technical article will limit to wire connections and routing inside of control panels. Let’s discuss now about tips and advices you should take into account when wiring the control panel:. 1. General tips These are some general points that should be taken into account when wiring the control panel. #1 Connections should be secured against accidental loosening. Correctly tighten terminal screws and where a connecting plug is fitted, use the clamps or screws provided to secure it to its mating socket. Connections should be secured against accidental loosening.
#6 Terminals and terminal blocks should be clearly marked and identified to correspond to the markings in the drawings. Ensure that identification tags and cable markers are legible, marked with a permanent ink and suitable for the environment where the panel is to be used. They should also correspond with those shown in the machine drawings and instruction or service documentation. Terminals and terminal blocks should be clearly marked and identified to correspond to the markings in the drawings.
#10 Flexible conduits and cables should be installed in such a way that liquids can drain away from fittings and terminations. Flexible conduits and cables should be installed 2. Conductor and cable runs #1 Conductors and cables should run from terminal to terminal without any intervening joins. This refers to making a joint in the middle of a wire or cable. If it is necessary for any reason then use a suitable connector or terminal block. Don’t use a twisted and soldered joint. Extra length should be left at connectors where the cable or cable assembly needs to be disconnected during maintenance or servicing.
Conductors and cables should run from terminal to terminal without any intervening joins. #3 The protective conductor should as far as is possible be routed close to the associated live conductors to avoid undue loop resistance. The protective conductor should as far as is possible be routed close to the associated live conductors to avoid undue loop resistance 3. Horizons music and arts appreciation for gr 10.
Conductors of different circuits This refers to wires and cables that are in the same enclosure but are connected to different parts of the system, for example power wiring that could be carrying high currents at 415 volts. Signal wires that may be connected to sensors and to the input terminals of a programmable controller and therefore carrying only low currents at 5 to 24 volts. When a conductor is carrying current, an electro-magnetic field is produced. This is more pronounced when the power is high such as may be the case for a powerful electric a.c. This field can cause a voltage to be generated in other conductors nearby.
It is possible for this so-called interference voltage to cause another circuit to react, causing a malfunction. When the current is switched on or off, the electro-magnetic field increases and decreases, rapidly causing, in effect, a radio signal. The effect is similar to the crackle that can sometimes be heard on the radio or television when something like a fridge switches on and off. This radiated signal can be and cause interference to the normal working voltages in the system.
This is known as Electromagnetic Interference or EMI. The Electro-magnetic Compatibility (EMC) Regulations require that these effects are minimized. Electromagnetic field trapped in conduit. Circuits which are NOT switched off by the supply disconnecting device should be either separated physically from other wiring and/or distinguished by color so that they can easily be identified as being LIVE when the disconnecting device is in the off or open position. A lamp inside an enclosure provided for use during maintenance is an example of such a circuit.
The control panel may be isolated but the lamp will require power so that the engineer can see while working on it. Reference // Industrial Control Wiring Guide by Bob Mercer.
Such factors include:. The insulation material;. The size of the conductor;. What it’s made of;. Whether it’s solid or stranded and flexible. These are all considerations which the designer has to take into account to suit the final application of the equipment.
A conductor is a material which will allow an electric current to flow easily. In the case of a wire connection, it needs to be a very good conductor. Good conductors include most metals. The most common conductor used in wire is copper, although you may come across others such as aluminium. An insulator on the other hand is a material which does not allow an electric current to flow. Rubber and most plastics are insulators. Preparing wire.
Insulation materials Wires and cables (conductors) are insulated and protected by a variety of materials (insulators) each one having its own particular properties. The type of material used will be determined by the designer who will take into account the environment in which a control panel or installation is expected to operate as well as the application of individual wires within the panel. As part of the insulating function, a material may have to withstand without failing:.
Extremes of current or temperature;. A corrosive or similarly harsh environment;. Higher voltages than the rest of the circuit.
Because of these different properties and applications, it is essential that you check the wiring specification for the correct type to use.
Outdated Content: This information is outdated and does not apply to the current version of IC². WARNING This tutorial is currently being updated to IC2 and may contain incorrect information. Forum post about IC2 Wiring by Alblaka: Firstly, do not act like redstone; you cannot place them diagonally to travel in a stair formation. They must be placed like stairs. Most machines will accept power from a wire on all 6 sides, but you (usually) only need one input. Will output power from all 6 sides (but only from one side at any one time), however don't cover the top of a, for obvious reasons. Starting simple this is the most basic set up without omitting a.
The max length for copper is achieved here. The cable is 4 blocks long. You lose if the current in the cable travels for too long, losing 1 upon reaching the 4th block, then another 1 for every 3 blocks after that. But if you use the most advanced wire, 'Glass Fibre Cable,' you can achieve a length of 50 blocks.
Does not apply to latest versions of IC2 Experimental (v2.2.x) This setup will not work as the BatBox is not a splitter and it doesn't have two outputs, it will accept input from 5 sides at the same time but will only output on the output face marked with dot. This is a simple buffer, it can be used to store for use without running the generator This is a simple 2x solar flower setup with a loop. This will enable you to spread around your Factory and not have it bottleneck in any particular spot.
Take note the BatBox connecting the generators to the loop. That way the will be evenly distributed around the area. In the center of the solar flower there is a wire, a normal,average wire.(because of advances in the programing of the wires they now allow to be connected up to 6 sides simultaneously opposed to the 3 side max in IC.) Now for something more advanced, the. This is an example of an improper setup of an MFE before I turn off the redstone as shown in the second picture and after I placed the 2 wires above the MFE will output one 128 EU packet and everything crispifies. (Latest IC2 Experimental versions do not do this) this caused a loop of power to be sent from the top of the MFE(output) back into the batBox hence killing the setup.(and wasting the wire because it couldnt handle the power and just melted) To properly use a MFE, you need to use a and gold or better wire. The MFE is used to scale the voltage up and the to scale it back down. Quite similar to real life and your local power grid.doing this increases the range of the power but needs a better.
The energy loss is less because you are sending less packets that are larger, they still lose over the cable but you lose less. Next is series of machines, and current splitting. You can have your machines in a row and power them from one MFE the excess is sent back to the MFE and stored. In this setup I have the maximum cable length without loss (to prevent continuous loss of power) and the measurements listed are from right to left and the last one receiving 0. The Eu splits evenly between each machine as it acts like a cable end.
And this is with an MFE output of 128 as you can see it is useless to make lines of machines any longer than 5 and 4 would be optimal as the last 2 would receive 8/2 = 4 each, which will power most common machines easily. You could use the 50 output if you wanted to power say 4 crystal chargers in a row. You can then save space and stack your machines in a feasible 3x4 array like so.

And the back to power them Next up is Miners and making them do what you want them to. In the first setup I have a solar flower powering a MFE = HVT = HVT = Miner.
This is a one way operation, but the miner can only accept so much at a time therefore the 2000 sent towards the miner will sometimes be rejected and get sent back. Causing loss each way. This can happen as often as once each frame causing massive power loss. A better way to do it is using. These accept input on all sides but the bottom, (which is the output).
However if you apply Redstone current it will make the top output and the bottom input. This can be used as a switch before sending Eu from the MFE =HVT. This way you can shut the whole operation down and let the MFEs charge up. The miner can be set up to automate with water streams as well. Peugeot 206 roland garros owners manual. However I use that lets you build a conveyor. This is easier then digging trenches and placing water buckets. It also can travel ridiculously long lengths, and never have to dig one block down.

This is similar to water running on iceblocks (if you can craft em) Take note that I have all but one of the 5 available sides of the miner covered as to direct the item toward the conveyor, and a small 3 long wall to stop the items from being shot over the conveyor. IndustrialCraft² Stuff.
