Ensuring machine safety in the workplace is a legal requirement and a moral obligation. Accidents and injuries resulting from inadequate safety measures can have devastating consequences for the individual and the overall well-being of the business. From physical harm to financial liabilities and reputational damage, the impact of workplace incidents can be far-reaching and long-lasting.
Staying current on machine safety regulations allows businesses to utilize technological advancements and innovative solutions. This article will explore the ANSI B11.0 updates and discuss how Wieland Electric can assist with safety services.
The Significance of Machine Safety Regulations
Workplace accidents occur far too frequently, resulting in injuries, fatalities, and economic losses. The Occupational Safety and Health Administration (OSHA) reports millions of nonfatal workplace injuries and illnesses annually. In 2022, the workplace fatality rate per 100,000 workers was 1.3 compared to 1.1 in 2021.
Beyond the human toll, workplace accidents also have significant financial implications for businesses. The direct costs of injuries include medical expenses, workers’ compensation claims, and potential legal fees. Accidents also have indirect costs, such as reduced productivity, damaged equipment, increased insurance premiums, and potential regulatory penalties.
The ANSI B11.0 Updates
Machine safety regulations exist to prevent workplace accidents and mitigate the associated risks. They are developed based on extensive research, analysis of accident data, and collaboration with industry experts. Moreover, these regulations set out guidelines and requirements for machine design, construction, installation, and operation.
ANSI B11.0 is a widely recognized American National Standard for machine safety. It establishes principles and regulations for the layout, installation, and operation of machines to reduce hazards and protect those who deal with them. It is also periodically updated to incorporate technological advancements, industry best practices, and emerging safety standards.
The following are some noteworthy changes to ANSI B11.0-2020 from the previous edition of the same standard:
Guidance on this standard and type-C standards has been revised and updated.
The roles of component suppliers, machine suppliers, and machine users were defined.
The standard now emphasizes the practicality of risk-reduction methods.
Guidance on dealing with existing (legacy) equipment has been updated.
Instructions on various topics were expanded, including prevention through design (PtD), achieving acceptable risk, and validating and verifying risk reduction measures.

The new IP67 ethernet switch from Wieland Electric enables reliable operation in harsh industrial and other environmental conditions
Industrial automation is increasingly relying on the decentralized and flexible connection of automation components. This also applies to IP or ethernet switches, which are no longer only mounted in the control cabinet, but also directly on the machine. In order to ensure the reliable operation of the network components under these circumstances, the devices must meet the requirements of harsher working environments. After all, they are directly exposed to harmful elements such as dust, moisture, and electromagnetic radiation. Wieland Electric offers a suitable solution for this with the new wienet IP67 switch.
The wienet IP-SWITCH UMS 8-W-M12 is equipped with robust metal housing and is used under the most adverse environmental conditions. Water splashes, other contaminants, and high temperatures of up to 75° Celsius are handled without any problems. In addition, the switch complies with the EN 50155 standard, making it suitable for the higher requirements of railroad applications. Fluctuations and interruptions in the power supply are tolerated, as are vibrations, shocks, and high humidity. The compact device is easy to maintain, features a long service life, and has high electromagnetic compatibility (EMC).
The plug & play feature of the new IP67 switch from Wieland Electric enables fast commissioning even without programming experience. Sensors and actuators can be connected robustly and reliably via eight M12 Fast Ethernet ports, which contributes to low failure rates. Its compatibility in conjunction with programmable logic controllers (PLCs) within the IEC 61131-2 framework also ensures reliable network operation with the lowest probability of failure.
Optimally suited for modular systems: The robust and compact IP67 unmanaged ethernet switch from Wieland Electric ensures reliable operation even in harsh environmental conditions.

Decentralized motor starter for easy planning and safe operation of conveyor systems
Motors in conveyor systems need to be switched off safely, but the wiring and energy distribution involved is usually very complex, involving bulky cable trays, and complex distribution boxes. As a result, Wieland Electric has developed a new motor starter that reduces the complexity of installation and improves the safety of conveyor systems. The podis MS 5HP is a compact, robust and user-friendly drive component with an integrated STO (Safe Torque Off) function. The safety function disconnects the power supply from the emergency stop circuits completely. As a result, the STO circuits no longer need routing through a central distributor and assignment to a specific energy branch. The system is less susceptible to interference and the installation work is more easily planned and carried out.
The motor starter podis MS 5HP from Wieland Electric makes the planning and installation of expansive conveyor systems less complex.
Safe Torque Off
The innovative combination of starter functions allows for the decentralized assignment of all of the energy of the STO circuits in the field. In addition, a superior level of safety (SIL 3, PL e) can be achieved with less effort. All the motor starters in an emergency stop circuit connect to the STO female sockets. The STO circuit monitors and operates through an auxiliary voltage generated in the field and also by a two-channel safety relay. Several STO circuits can operate from one power supply.
Using an energy bus system such as the podis 5G6 from Wieland Electric further enhances decentralized motor control. The energy distribution for several motors and starters can combine on one line with only a single feed. This saves space in the cable trays and the wiring in the distributor panel is much more straightforward.
Multiple Motor sizes, One starter
The podis MS 5HP covers motors with a power range from 0.3 Hp to 5 Hp (0.25 kW to 4.0 kW), up to 5 different motors. This helps reduce storage and administration costs. With only one order option for multiple motors, the procurement and materials management processes also require less effort.
Installation and commissioning are simple as well. DIP switches, for example, can be programmed on the device or with a web tool. The web configurator guides the user step-by-step through the different options. To access the configurator, simply scan the QR code on the front of the device.
Use the podis energy bus system for a complete electrical installation of conveyor systems.
Approvals & Protection Rating
With international approvals, CE, cULus from Q4 2021, the podis MS 5HP is suitable for worldwide use. In addition, the disconnect switch is in accordance with UL 508. The integrated service switch safely turns off drives for maintenance or repair work. Individual conveying lines can disconnect from the power supply without the system as a whole shutting down. A special integrated power supply generates the 24V DC auxiliary voltage required to supply the connected sensors. It does not use the neutral conductor and hence makes additional separate wiring unnecessary. This saves time and reduces material costs. Designed compliant with protection class IP65 and the NEMA12 standard relevant for the US market, the podis MS 5HP is also suitable for use in harsh industrial environments.
