Electrical Control Panel Design
Control panel design is simple. Cost is a factor. But, so is an appearance. Simple operator controls and reliable operation. Simple panel designs are less expensive to produce. Easier to operate and maintain.
It helps when you understand design is a process. Often you think you know exactly what you want when you get started. But find you want something different when you’re done.
When you first design the requirements on paper they seem unorganized. That is normal. Not everyone gets everything right the first time. Designing is a process and it takes time to get it right.
Rewrite your requirements until they are organized and clear. Understand what you want. Write it in clear language. Then proceed with the actual hardware design.
Good control panel design includes both physical and electrical requirements. Do not produce schematic drawings without producing physical layout drawings. Solve potential problems by alternating between the physical and electrical.
Good control panel design includes accurate physical layout drawings and schematic drawings. This minimizes problems. Delivery delays improved, due to problems being resolved during production or testing.
Use the standard Electric Code clearance for power wiring. And the required clearance around heat producing devices.
Identify each power circuit and determine the required wire size and circuit protection. The right wire size ensures the circuit can deliver the required load current. The right circuit protection ensures the wiring doesn’t overheat and start a fire.
Determine the best power component type to use based on function. Then select the right size based on voltage and load current. The right type ensures it’ll function as desired and the right size ensures it will handle the load.
Always start with simple control components. Relays, Timers, etc.. When simple does not get the job done. Use something with more functionality. Like a programmable Smart Relay or a Programmable Logic Controller (PLC). These provide more functionality. But they need a computer and programming software. And someone who knows how to program the desired functionality.
Always start with simple operator devices. Pushbuttons, Pilot Lights and Digital Panel Meters. For a stylish appearance add a Color Graphic door. When simple doesn’t get the job done. Use a color touchscreen display as the human interface. This provides more functionality. But it also requires a computer and programming software. And someone who knows how to program the desired functionality.
Control panel designers use the best products. This is subjective based on product awareness. Experienced control panel designers are aware of the array of products available. This allows them to compare and use products that provide the best balance of price.
