Fully redundant power supply units (Nx2 configuration)

If the system has a redundant Controller, it is recommended to have a PSU configuration that is tolerant of a PSU or mains failure. In the Nx2 configuration the required PSU capacity is doubled. The the second part is connected to an independent power feeder system.

AC power feeders supply the power for the entire Safety Manager system. To limit the load on the feeder, you are advised to put no more than 2 power supplies on one feeder.

This configuration has the following characteristics:

The PSUs can deliver twice the power required by the Safety Manager system.

System continues normal operation when one PSU fails (single-fault tolerant).

System continues normal operation upon a failure in the power mains.

See “Power Supply Units configurations (2 examples for each configuration)” below for details.

Power feeder configurations

If a customer provides DC power feeder(s) for the Safety Manager system, power supply units (PSUs) may not have to be installed. However the Honeywell SMS Feeder Unit 24V or Feeder Unit 48V is installed.

If a customer provides one DC power feeder cable for the entire Safety Manager system, a single failure in the mains power leads to a system stop with undefined results.Honeywell 8302A Industrial Automation Module

Redundant DC power feeders are normally supplied with the Safety Manager system. In this case, de coupling diodes have to be used.

The Honeywell SMS Feeder Units already contain de coupling diodes.

3701/55 ADAPT (ESD) Emergency Shutdown Device

Description

The 3701/55 Emergency Shutdown Device, (ADAPT ESD) is a safety PLC with a graphical logic programming interface and integrated overspeed detection. ADAPT ESD is designed for emergency shutdown of rotating machinery such as steam, gas, and hydro turbines, expanders, and other process equipment.

ADAPT ESD is a compact, standalone, triple-redundant, safety shutdown device that is designed to meet a broad range of user scenarios and applications. The design offers an electrical and mechanical package with attention to reliability and availability as well as extensive selfdiagnostics and compliance to industry standards.Bently Nevada 128276-01E Relay Module for Industrial Automation

Inputs

Inputs to the system are processed using three CPU modules to provide triple modular redundancy (TMR). Each CPU processing module processes two unique speed input channels, for a total of six speed channels for the system. The processing modules also monitor an array of 32 discrete (DI) and process variable (PV) signal inputs. Twelve channels of this input signal array may be configured either as discrete inputs or 4-20 mA analog inputs. Remaining channels in the array are reserved for discrete input signals only.

Outputs

Machinery shutdown functionality of the 3701/55 ADAPT ESD system is actuated by TMR relay output modules. Each relay output module has five relays with a level of configurability that accommodates a variety of applications and requirements. Four of the five relays in each module are used to annunciate system logic. The remaining relay reflects the OK/NOTOK status of the associated protection path. The Bently Nevada Monitor Configuration software provides a graphical interface to configure relay logic. The state of each relay is determined by the system inputs and configured system logic in conjunction with the control state of the relay. Relay control states depend on the application, and may be set as normally energized/de-energized and independent one-out-of-one, (1oo1), voting or TMR two-out-of-three, (2oo3), voting. Each CPU module in the system has two, internally powered, 4-20 mA recorder outputs controlled by the full-scale speed set by the user through the Monitor Configuration software.

Compliance

The 3701/55 ESD complies with most applicable technical regulations and standards.

North American general safety, CSA certified

CE, Low Voltage and Electro-Magnetic Compatibility

Functional Safety certification (SIL)

CE, Machinery Directive

North American, Hazardous Area certification, CSA certified

European ATEX and IECEx Hazardous Area certification pending

3701 ADAPT ESD Overview

Typical (and recommended) applications of the ADAPT ESD will use a triple modular redundant architecture. In this configuration, each processor module physically connects to an array of 32 input channels, 12 of which are configurable as discrete inputs or 4-20 mA analog inputs, as well as two speed inputs. The Bently Nevada Monitor Configuration software allows you to configure large combinations of logic blocks in order to manage the system trip logic. This logic dictates how the trip mechanisms for the system are driven. The ADAPT ESD system can drive 12 independent trip relays. Of the 12 relays, six of these signals can optionally be configured for two-out-of-three,(2oo3), voting. In the 2oo3 arrangement, the system activates a relay only when any two of the three CPU modules drive to trip. In independent mode, or one-out-of-one voting, any single CPU that drives to trip will cause an assigned relay to activate on the corresponding output card. For the highest safety, the system should be configured in “deenergize to trip”, or “normally energized” mode so that loss of power will not result in a machine running unmonitored.

Why 2025 will be a pivotal year for Amazon’s Zoox robotaxi division

LAS VEGAS — This year is expected to be a pivotal one for Amazon’s self-driving car unit, Zoox, as the company plans to expand operations and commercialize its robotaxi business.

Zoox plans to start offering rides to the public “very soon,” expand its operating area and “substantially” increase its fleet of self-driving cars by 2025 from the current few dozen, according to co-founder and Chief Technology Officer Jesse Levinson.

“It’s a lot of work, but we’re excited about it,” Levinson said during a 40-minute tour of Las Vegas in one of the company’s self-driving taxis. “We’re very happy with the progress we’re making.”

While some investors have lost enthusiasm for self-driving cars, Zoox’s plans are still on track, and they’re not alone, with traditional automakers such as General Motors, Ford Motor and Volkswagen having disbanded some of their self-driving divisions in recent years.

Founded a decade ago and acquired by Amazon in 2020 for $1.3 billion, Zoox has been testing its purpose-built self-driving taxis on public roads since early 2023. The company is currently testing the vehicles, which don’t include manual controls like steering wheels or pedals, in three cities: Las Vegas, San Francisco and Foster City, California, where it’s headquartered.

Las Vegas is expected to be Zoox’s first commercial market. The company hopes to launch an “early rider program” in the coming months before opening it to the public later this year. Zoox began testing in San Francisco in November 2024, and will later launch the program there, the company said.

Levinson said Zoox also plans to expand to Miami, Austin, Texas and other cities, but the company has not announced a specific timeline for operating in those cities.

“Hopefully by the end of the decade, if you’re in most major cities in the United States, this will be your favorite way to get around,” Levinson said.

Amazon does not publicly disclose its investment in Zoox or other early-stage businesses, but says such investments are seen as emerging long-term initiatives to assist the company and its customers.

Take a Self-Driving Taxi

Zoox’s self-driving taxis are different from other taxis because they don’t have human drivers from the start. This is a departure from the route taken by Alphabet-backed Waymo, the U.S. leader in robotaxis, which has retrofitted conventional vehicles with self-driving car capabilities.

Some have described vehicles like Zoox’s self-driving taxis as “boxes” or “toasters.” The doors open in the middle, and seats are arranged in two rows, with no room for a driver. GM’s Cruise had also planned to launch such a car, the Origin, but canceled production after facing problems following an accident involving a pedestrian in October 2023.

“I think the vehicle itself is interesting,” Sam Abuelsamid, an autonomous driving expert and vice president of market research at Telemetry Insights, said of Zoox. “The size and shape of the vehicle are right.”

Driving on the outskirts of the Las Vegas Strip on a sunny morning, the Zoox self-driving car performed well. It turned well and drove confidently but not aggressively. There were some questionable choices along the way, such as choosing to stay in a long line instead of going around a large trailer, but overall the vehicle performed well.

Levinson said the Amazon-backed company has been working toward autonomous driving over the years of testing. Self-driving cars can’t break the law like many human drivers do, but they can’t be too cautious or aggressive, either, because that could lead to accidents or conflicts with other human drivers.

The future of the business

If Zoox can develop and begin commercial operations as planned this year, it will arguably be far behind Waymo in the field of self-driving taxis.

“I don’t want to suggest that this business will be commercially meaningful this year…but it will be very useful because customers will be able to get value from it and really use it to go anywhere. We’re excited about it,” said Zoox’s Levinson. “Because safety is paramount, we’ve taken a fairly conservative and robust approach to expansion and promotion.”

GM’s Cruise self-driving car unit was once an industry leader alongside Waymo until the company grounded its self-driving taxi fleet and announced the end of commercial operations late last year. This followed an accident in October 2023 in which an external investigation found that the company misled or deceived regulators.

Providing public ride-hailing services is just another step in the challenge of commercializing self-driving cars. Waymo began offering supervised rides to the public in Arizona in 2017, followed by unsupervised, driverless rides in 2019. The company has slowly expanded to hundreds of self-driving cars in four markets and currently provides more than 150,000 paid rides per week.

“From a technology perspective, I think Zoox is going in the right direction. I’m a little unsure about the business model,” Abuelsamid said. “The technology is maturing. It’s not perfect, but it’s getting better.

“But everyone is trying to figure out what the operating model is that will actually recoup costs and make money,” he continued.

The self-driving taxi industry has proven to be far more challenging than many imagined in the late 2010s, when GM, Waymo, Lyft, Uber and many others entered the market with grand ambitions to commercialize the technology and replace human drivers.

Companies have proven that self-driving cars are viable, but the costs have been far higher than initially expected, and the payback has taken longer than expected. Not to mention, some reports of problems on the road, and it faces uncertainty around regulations and liability.

Other companies, most notably Tesla, have announced ambitions for a self-driving taxi business, but have failed to develop driverless cars or a commercial self-driving ride-hailing business.

Meanwhile, Waymo continues to expand. Last year, the company announced an expansion of its partnership with Uber to offer its self-driving taxi service exclusively on the Uber app starting in early 2025, bringing the service to Austin and Atlanta. Waymo also expects to expand in the next few years. Expanding to Miami in early 2026.

“They are absolutely the leader,” Abuelsamid said. “They are the only company currently operating a true self-driving taxi service at any scale; they are the largest company.”

Troubled electric car maker Nikola files for Chapter 11 bankruptcy

DETROIT — Nikola Corp., the auto startup once a favorite of Wall Street analysts and retail investors, has filed for Chapter 11 bankruptcy protection after failing to find a buyer or raise additional funds to stay afloat.

Nikola said Wednesday it plans to initiate an asset auction and sale process, pending court approval. The company said it has about $47 million in cash to fund bankruptcy activities, conduct the sale process and exit Chapter 11.

“Like other companies in the electric vehicle industry, we are facing a variety of market and macroeconomic factors that have impacted our ability to operate,” Nikola CEO Steve Girsky said in a press release. “Unfortunately, our best efforts have not been sufficient to overcome these significant challenges, and the board has determined that Chapter 11 represents the best path forward for the company and its stakeholders under these circumstances.”

If approved by the court, the proposed bidding process would allow interested parties to submit binding offers to acquire Nikola’s assets free of its debts and certain liabilities.

The bankruptcy filing marks the end of a years-long decline for the Phoenix-based company. At its peak in 2020, Nikola’s valuation surpassed Ford’s $30 billion deal with General Motors, which was considered the pinnacle of auto startups going public through reverse mergers and special purpose acquisition companies.

The company’s decline has been years in the making, sparked by scandals and lies by its founder and former chairman and CEO Trevor Milton. The fluent, energetic and disgraced executive was convicted of wire fraud and securities fraud in 2022 for misleading investors about Nikola’s operations and zero-emission technology.

The controversies were first publicly disclosed by short-seller Hindenburg Research after GM struck a deal with the Detroit automaker that included a $2 billion stake in the startup.

Nikola’s core products are all-electric and fuel cell electric semi-trailer trucks, which the company began producing in 2022. As of the third quarter of last year, the company had produced only 600 of these vehicles since then. Many of those vehicles have been recalled for defects, costing the automaker tens of millions of dollars.

Since transitioning from chairman to CEO in 2023, Girsky has pushed Nikola forward, including producing zero-emission trucks, but the company has been running on less capital.

Nikola warned investors on its third-quarter conference call that it has enough cash to sustain its business through the first quarter of 2025, but not much longer. Nikola reported a cash balance of $198 million at the end of the third quarter.

Comau’s wearable exoskeleton MATE-XT provides ergonomic health support to John Deere’s Brazilian parts distribution center

John Deere deploys multiple MATE-XT exoskeletons to bring better ergonomic sustainability to its employees

Based on EMG analysis, the wearable robotic device can effectively reduce biomechanical risks by 50%, while keeping muscles at rest for 98.5% of physical activity time

The slim, highly breathable exoskeleton provides ergonomic all-day support, designed to improve the quality and precision of repetitive tasks

MATE-XT is waterproof, dustproof, UV-resistant and heat-resistant, making it an ideal choice for harsh working conditions and environments

Comau has equipped John Deere with multiple MATE-XT wearable exoskeletons to help maintain the physical health of workers, reduce physical stress and reduce the ergonomic risks they face in parts logistics operations. MATE-XT accurately replicates all shoulder movements, helping employees perform their work comfortably by reducing muscle fatigue without limiting mobility or feeling cumbersome. It is ergonomically designed and easily adjustable to accommodate a variety of body types – changing the length of the shoulder straps and the required level of assistance can be quickly achieved according to the worker’s body or the type of work in just a few simple steps. Comau worked closely with John Deere to deploy the exoskeleton in daily operations and conduct hands-on training at John Deere’s 75,000 square meter parts distribution center in Campinas, São Paulo State, Brazil.

With parts often delivered the next day, John Deere employees must select, sort and pack hundreds of parts every day. This work involves repetitive movements of the arms, shoulders and back. The highly breathable design of MATE-XT, like wearing a backpack, provides comfortable, ergonomic all-day support to improve the quality and precision of manual work. In addition to providing efficient postural support, MATE-XT is also EAWS (Ergonomic Assessment for Work) certified, which allows John Deere to objectively measure ergonomic improvements and expected benefits in terms of reduced muscle fatigue and execution speed.

Even when handling small and light objects, repetitive movements that seem effortless can take a toll on the body. To help John Deere quantify the benefits of using MATE-XT, Comau performed an electromyography analysis of ergonomic risk factors. MATE-XT allows muscles to rest 98.5% of the time (compared to 2.4% without MATE-XT).

In addition, Comau’s MATE-XT ensures proper muscle balance while optimizing the energy expenditure required to stabilize and maintain the weight of the arm. With the exoskeleton, only 10% of the operator’s maximum force is required to maintain arm stability. In addition to specific performance-based results such as process optimization and productivity gains, it also improves employee comfort and well-being. MATE-XT is helping John Deere reduce ergonomic risks and reduce muscle overload by 68%.

Laerte Scarpitta, General Manager of Comau Americas, said: “We extend our commitment to providing customers with innovative automation technologies to exploring new ways to ensure that workers can carry out their daily work safely in various markets and different application environments. With MATE-XT, an easy-to-use wearable exoskeleton, John Deere effectively reduces muscle fatigue and reduces mechanical stress on workers’ backs, waists, arms and shoulders, creating greater added value and more practical benefits. This is another example of the value that robotics brings to us.

Hug, not bugs Reduce unplanned downtime to predict and gain opportunities

For enterprises, sudden equipment failure is like a bug hidden somewhere. You know it exists, but you don’t know when it will appear. This kind of “anxiety” is a huge crisis for any enterprise.

How to solve this bug and turn the “danger” that may appear at any time into an “opportunity” for strategic planning has become the key to the problem – the choice of predictive analysis software has become a strategic issue for enterprises in this process.

01

The premise of eliminating bugs

Predictive analysis and “foreknowledge”

The concerns about potential crises such as unplanned downtime have led to a huge increase in market demand for predictive analysis software:

“According to relevant research data, in the next few years, the global predictive analysis market size will grow from US$12.5 billion in 2022 to US$38 billion in 2028, with a compound annual growth rate of 20%. ”

This broad prospect is due to the increasing maturity of artificial intelligence (AI) and machine learning (ML) technologies and algorithms, new methods for large-scale deployment of predictive analytics, and the availability and maintainability of data and systems.

Faced with the wide variety of predictive analytics software on the market, enterprises must consider variables such as return on investment (ROI) when weighing their potential deployments. The final choice of predictive analytics software “is hardware-independent”, “is it the best way to leverage existing software investments”, “is the solution easy to deploy, maintain and expand” and many other factors are all issues that enterprises need to consider.

02

Let the tools fully integrate

The power of human insight

Human experience and intuition play an important role in assessing potential crises, but due to differences in positions and departments, different employees are in different specific professional fields, and therefore have very different “experiences” in troubleshooting. For example, people from engineering or operations backgrounds often have very different ways of thinking when facing the same problem.

Although many predictive analytics solutions can provide abnormal alerts, if there is insufficient experience and insight, the imminent crisis may be ignored when facing abnormal alerts. Therefore, while enterprises use “human insight”, they must also acknowledge the subjectivity of the team in discovering and solving faults. At this moment, the advantage of “tools” is highlighted.

Rational and precise digital technology and human perceptual “experience” complement each other. It can “predict” – provide timely fault diagnosis alarms through real-time data, and “analyze” – explain the reasons for the alarm. The closed-loop predictive analysis strategy enables enterprises to collect, organize and analyze data, including real-time sensors, historical operations and financial impact analysis data.

Based on these data, users can immediately lock in the crux of the problem and let the anomaly disappear in the bud. More importantly, record and reuse relevant data to achieve continuous improvement.

03

The importance of fault diagnosis

But the “early warning” of the machine is not 100% accurate. Sometimes the alarm is not a warning of unplanned downtime, but just a sensor failure. This “oolong” greatly reduces the accuracy of the analysis. Unreliable data will cast a shadow of “wolf coming” on analysis and decision-making.

Therefore, excellent predictive diagnostics require “the right medicine for the right disease”, providing precise, real-time insights through customized data and diagnostic tools. AVEVA’s predictive maintenance solution estimates the time when a failure may occur through efficient and accurate fault diagnosis methods, helping companies accurately prioritize maintenance.

The prediction of the time of failure helps operations and maintenance teams “have a plan in mind” to determine whether to let the asset run until the next planned maintenance stoppage or initiate an emergency stoppage. This also enables the team to more accurately predict potential supply chain problems and consider the preparation time of spare parts. At the same time, prescriptive analysis can also provide actionable tasks to remedy the problem.

In this way, unplanned downtime is eliminated.

Conversely, relevant predictions can also help operators determine whether to postpone planned maintenance tasks. Plant personnel can schedule maintenance and assess risks more effectively, helping companies prioritize safety and profitability.

04

And “Hug” with Data

Make the most of data

As digitalization advances at a high speed, industrial companies are collecting more data than ever before. According to statistics, 50% of all industrial data was generated in the past two years.

With the help of various software and hardware, enterprises may have a large amount of data in their hands to monitor their assets reaching a certain threshold, such as temperature, heat rate, fuel consumption, power consumption, etc.

While these indicators may represent valuable insights, they are static. When conditions change, enterprises need to use multiple parameters to track and anticipate any deviations of assets. Therefore, a more dynamic production environment requires a more dynamic process.

In order to explore the potential of data to a greater extent, enterprises must establish a comprehensive data infrastructure “from engineering to operations to asset management to corporate finance” and use solutions that can integrate all relevant information sources.

AVEVA’s predictive maintenance software solution analyzes historical behavior, takes into account multiple thresholds and change patterns, and tracks the actual condition and real-time operating conditions of assets in real time to predict possible problems in the future.

This makes maintenance planning more effective, avoids over-maintenance of assets, and provides a clear view of the relationship between asset models, fault conditions, fault modes, sensors and actual fault matching information, so that everything is under control and strategic planning is possible.

Stellantis delays Ram electric pickup truck launch to 2025

DETROIT — Stellantis is delaying the launch of its Ram all-electric pickup truck from this year to the first half of 2025 as the transatlantic automaker continues testing the vehicle.

Chief Executive Officer Carlos Tavares on Tuesday declined to give specific reasons for the delay in the launch of the electric truck, which is expected to be followed by a range-extended “Ramcharger” with a generator and gas engine.

“We have a very large workload and we want to validate the product in a very careful way, so we’re taking our time and making sure we can handle the peak,” Tavares said during an online media event. “We don’t want to rush it… It’s better to take a few weeks to validate it correctly than to rush it and then make a mistake in quality. That’s what we’re doing now.”

The all-electric pickup is expected to go on sale by the end of this year, with the Ramcharger to follow in the first quarter of 2025. The automaker declined to say when the Ramcharger would be available.

Tavares said work needs to be completed on the Dodge Charger Daytona and Jeep Wagoneer S EV, both expected to go on sale by the end of the year, before moving on to the new trucks.

Stellantis’ upcoming electric pickup is the first to be built on the company’s new “STLA framework platform,” designed for large trucks and Jeep SUVs. The platform is expected to be a “multi-energy platform” that can accommodate both internal combustion and hybrid vehicles, as well as electric models that use batteries, fuel cells and extended-range electric propulsion systems.

Stellantis said the Ramcharger Extended Range Electric Vehicle can operate as a zero-emission electric vehicle until the battery is depleted, then the onboard generator (powered by a 27-gallon, 3.6-liter V6 engine) kicks in to power the vehicle.

The automaker reconfirmed Tuesday that the REV can travel 500 miles on a single charge, while the Ramcharger is expected to have a class-leading range of 690 miles.

“We are managing the peak period between the products that are coming,” Tavares said. “There will be a lot of product coming to the U.S. market in the coming months.”

Stellantis’ U.S. electric vehicle offensive couldn’t have started at a worse time for the automaker, as President-elect Donald Trump has vowed to roll back or eliminate many of the Biden administration’s goals and funding for all-electric vehicles.

Last week, it was reported that Trump’s transition team plans to eliminate the $7,500 consumer tax credit for electric vehicles as part of a broader tax reform bill. The move would make good on Trump’s campaign rhetoric about eliminating such incentives and electric vehicle programs.

Tavares, who has criticized government regulations on electric vehicles but has also touted their benefits, said the company “will adapt” to any changes made by the Trump administration.

Correction: Stellantis is delaying the launch of its all-electric Ram REV from this year to 2025. The Ramcharger truck is scheduled to launch in the first quarter of 2025. A previous version of this article misstated the timing of the Ramcharger.
