As the name implies, a manual electric motor starter is used to turn a motor on and off using a button or switch mounted directly to the wall or machine cavity. However, switching is only part of the function. The starter also controls the current, establishing and interrupting electric power to prevent the motor from drawing too much current and overheating or burning out.

This functionality provides an effective motor starter design solution.In industrial applications, manual electric motor starters offer ideal industrial motor overload protection while ensuring safe and low-cost operation.Common uses for manual electric motor starters include low-horsepower, single-phase motor loads, such as small air compressors and exhaust fans.

A pilot light encased in the panel illuminates to communicate with the operator. By replacing the neon pilot light indicator with a more efficient LED lamp, the client’s manual electric motor starter would provide users with a longer-lasting bulb that is much more efficient.

However, the manufacturer’s design specifications would not work with any available standard LED indicators. To save the client the expense of redesigning the motor starter units themselves, VCC designed a custom panel mount indicator solution tailored to very specific design requirements, including:

• Four different voltage ranges

• Red and green color options
• High visibility during daylight hours
• Wire leads 4.25” long
• LED width at tip not to exceed 0.40”
• Entire voltage range recognized by cULus
• Compliance with REACH and RoHS

To achieve the client’s goal of replacing its neon indicators with energy-saving LED indicators, VCC designed eight custom additions to the L34 Series, one red and one green version for each of the following voltage ranges:

• 110-120VAC/DC
• 110-240VAC/DC
• 208-277VAC/DC
• 440-600VAC/DC
•  

For maximum daytime visibility, the custom VCC L34 Series indicators provided a 120-degree viewing angle.

The L34 Series indicators were designed to snap into place without the use of additional hardware. Color-coded wire leads also improved assembly speed during production.

VCC used the L34 Series to enhance the design with custom and rugged LED indicators, which included a cylindrical housing that could fit inside a small domed lens, offering energy-saving benefits. The indicators use a snap-fit for installation without additional hardware, making them ideal as custom panel mount indicators.

In addition to red and green indicators, the L34 Series includes yellow options for greater flexibility in visual communication. While there are several standard options in the L34 Series, VCC can customize a solution to fit a wide range of unique design specifications, as seen in this case study.

By upgrading from a neon indicator to custom L34 Series indicators, the client and its end users can enjoy the following benefits:

Energy Efficiency Benefits of LED Indicators

• Significant Energy Savings: Up to 50 percent less energy consumption with energy-saving LED indicators.

• Extended Bulb Life: Lamps last four times longer than neon, reducing downtime.

Daylight Visibility for Enhanced Safety

The brightness and viewing angle of the design ensure the end user can see the status of the motor starter at all times, improving operator safety. This constant status visibility supports the starter’s role in industrial motor overload protection.

Custom Fit Prevents Costly Redesign of Motor Starter Units

The custom panel mount indicators provided in the L34 Series saved the client from the costly endeavor of redesigning the motor starter units to accommodate standard illumination components.

Streamlined Production Times with Snap-Fit Design

Production times were streamlined thanks to color-coded lead wires and snap-fit LED components, offering a practical motor starter design solution.

The VCC team applied extensive engineering expertise to quickly design a prototype that met the client’s unique specifications. The custom solution prevented the client from having to redesign its manual electric motor starter units while providing a long-lasting, energy-efficient solution.

VCC makes sure that every system upgrade achieves maximum operational clarity and reliability through specialized engineering support. Beyond standard components, our Custom Panel Mount Indicators (PMIs) provide precise HMI feedback, optimizing designs with bi/tri-color LEDs, custom wire lengths, and specific environmental ratings to support reliable operation in harsh industrial environments. For complex internal layouts, VCC creates Custom Light Pipes, using advanced light simulation and rapid prototyping to deliver uniform illumination while providing key system-level benefits like isolating PCBs for essential ESD protection, enhanced thermal management, and the energy efficiency benefits LED technology offers.
