Raising elevator performance!

Control Techniques’ E300 elevator drives have been selected for a major hospital modernisation programme in Mexico that will eventually see hundreds of new lifts installed across the country. Carlos Silva SA – a Barcelona-based elevator control specialist – won the tender to supply 50% of the elevator control systems required in the first phase of the modernisation programme.

After many years of successfully using previous-generation inverters from Control Techniques, they chose the latest E300 drives for this new project.

Mexico recently embarked on a project to fully modernise many of its public city hospitals including those in Mexico City, Guadalajara, Tampico, Toluca, Merida, Ciudad Valles, Ensenada, Nuevo Leon and Chihuahua. The new lifts for these hospitals have to fulfil a varied range of criteria, such as low and high speeds, small and large cabins, single or multi-cabin groups and few or many stops. The brief requires the elevators to be able to cope with high traffic on a 24/7 basis and have to be appropriate for the use of both staff and the general public. Moreover, the lifts have to operate with outstanding reliability in the high temperatures, humidity and altitude associated with most Mexican cities.

“Control Techniques is one of two inverter manufacturers we use as standard. We are particularly impressed with the E300 elevator drive because it is able to offer better comfort levels, providing tight motor control at all speeds, in all situations,” explains Josep Oliva, Engineer at Carlos Silva.

In the elevator industry, ride experience is the true test of quality. Thanks to the unique motor-control algorithm and microprocessor technology within the E300 elevator drives, ride comfort is assured. Be it standard AC induction motors or high-efficiency permanent-magnet machines, the fast current loop serves to guarantee vibration-free motor control and smooth cabin movement.

“We also like the easy adaptability of the E300 to any type of encoder,” adds Mr Oliva. “As a result, we only need to change a parameter value rather than a whole encoder board.”

The flexible built-in encoder interface on the E300 supports 16 different encoder types without the need for additional interface cards. Incremental encoders (such as AB and SC), absolute encoders (SC.SSI, SC.EnDat, SC.Hiperface, SC.SC and SC.BiSS), and absolute comms encoders (EnDat and BiSS) are all supported out-of-the-box.

Carlos Silva has been using Control Techniques products since the early 1990s, including the previous-generation Unidrive SP. In comparison with previous-generation drives, Mr Oliva likes the E300 with its full range of elevator functionality integrated in the base firmware, as it avoids the need for additional cartridges. Other features admired by the Carlos Silva team include the Safe Torque Off [STO] input as it allows them to go without the two motor contactors, and they are also impressed by the advanced static auto-tune function.

Control Techniques drives offer contactorless operation in elevator applications. The EN81-20, EN81-50 TÜV certified STO function provides a highly dependable method for preventing the motor from being driven. The benefits of switching to a contactorless solution include simplified electrical installation, reduced EMC issues, less acoustic noise, improved system reliability and lower system costs.

Regarding static auto-tune, this function ensures encoder offset detection and optimum current-loop configuration without the need to lift the brake or de-rope the system, significantly speeding up the commissioning process.

“Importantly, Control Techniques helped us during the size selection process for these projects, minimising the risk of future problems as a result of the challenging operating environment,” states Mr Oliva. “In fact, whenever we are developing a solution for a project, we always get good advice from Control Techniques regarding the features and functionality of their inverters.”

To date, 78 elevators have been delivered as part of the hospital project’s first phase, although there are potentially more than 5000 to install in total throughout the lifetime of the entire project.

“We are happy with the result of the first phase and happy with the performance of the inverters, which help us comply with the new EN81-20 regulations concerning safety rules for the construction and installation of lifts. We’ve had no problems whatsoever.”

Due to the hospital project’s success to date, Carlos Silva recently became the provider of elevator controls for a second major project in Mexico. This project entails the installation of 75 elevators in 18 stations on a new urban train line in Guadalajara.

“The requirements for the train station lifts are completely different,” explains Mr Oliva. “For instance, all lifts operate at the same speed, with a maximum of three stops. However, we have again specified the E300 drive from Control Techniques to ensure high levels of ride comfort, robustness and reliability.”

Tiny sensors.

Laser Components can now provide custom ball lens profiles on the end faces of silica fibres. The plasma-based CMS process with ring-of-fire technology supports fibre diameters of 200, 365, 400, 550 and 600 μm, including other diameters within the limits of the equipment. For fibres used in medical applications, end-face processing can be carried out in a clean room in accordance with ISO 13485. The entire process is also compliant to ISO 13485 hygiene requirements.

High sterile standards are important since these fibres with spherical lenses are often used in medical technology applications to optimize radiation characteristics in endoscopes for example. The rounded surface of the ball lens reduces the risk of injury during the operation whilst at the same time controlling the beam characteristics of the laser. The same type of fibre tips is also used in other applications for coupling light sources with the fibre.

The company can meet all customer demands from single fibres to small series and, upon request, we can also conduct research projects. Ball lens fibres can also be integrated into OEM products. Other fibre tip modifications are also available upon request.

Standing the heat!

Manufacturers are now investigating how they can best apply Industry 4.0 digitalisation processes to existing production plant environments in order to improve productivity levels and reduce costs. A direct consequence of this approach includes implementing a more modular approach to production platforms. This can involve either the application of new modular machines into a production line or the retrofitting of existing installed equipment to support a more modular and decentralised interconnected control system solution.

This strategy can now be followed for some of the harshest environmental plant conditions, such as those where equipment might be sited in areas with high operating temperatures. In the past, limitations in the operating performance of a connector have often meant that equipment has had to be hard-wired in such situations. However, Harting’s new Han® High Temp range of connectors now supports the flexibility of applied connectorisation in such conditions. As a result, reduced wiring complexity means that such an installation can be optimised and maintenance costs reduced.

Typical end-user applications include support for modular production cells within metal production foundries and rolling mills, including integrated electrical heating control feeds to die-cast tools and electric furnaces which may be applied in various high-temperature material processing areas. In addition, they can significantly extend the service maintenance intervals of integrated removable mould tools within modularly designed plastics injection moulding machines for the latest high-temperature materials, resulting in reduced line downtime.

Similarly, opportunities may be found in tyre manufacturing and chemical processing plant environments.

Harting has used its considerable technical expertise to develop special connectors for providing reliable solutions for such high-temperature environments. For example, bulkhead-side connector seals must not melt or adhere to other integrated component parts over the full operating temperature range. Consequently, Harting has opted for a non-stick coated high-temperature-resistant rubber version, which avoids bonding between the hood and housing even if they are left mated for a number of years.

Many of the hood and housing coatings and lacquers available on the market are not suitable for long-term use at high temperatures as they can cause melting which can, in turn, lead to mated parts sticking together. Thanks to the application of a special surface treatment of the aluminium die-cast hoods and housings, Harting has been able to dispense with any potentially detrimental additional protective coating finish.

The insulating body and contacts must both withstand the high ambient conditions of the location and the additional heat generated inside the housing when under mated load. Harting has selected high-temperature-resistant copper alloy contacts that maintain constant electrical properties when heated. In addition, high-temperature LCP plastic insulators ensure long service life.

As a result of the above mentioned features, Harting’s Han® High Temp connectors are able to permanently withstand operating ambient conditions of +200°C, provide extended operating lifetimes and ensure reduced line downtime compared to competitor solutions.

Smart sensor for the IoT.

Generating, transporting and processing information are central tasks in the Industry 4.0 environment. The basis for all the information is intelligent sensors which provide the required input. With the Balluff BOS 21M ADCAP they have a newly developed optical multifunction sensor, the BOS 21M series.

The versatile all-rounder uses red light and lets you choose from among four sensor modes: background suppression, energetic diffuse, retroreflective or through-beam sensor. All the sensor functions can be configured over IO-Link while the system is running, so that a remote teach-in can be initiated by the controller.

In addition the sensor detects actual operating conditions, collects and processes information and provides far more data than just the switching signal over IO-Link. Detection signals are prepared and pre-processed in the sensor. This relieves the burden on the system controller and reduces data volume on the fieldbus systems.

Comprehensive, smart diagnostics functions provide important information such as life expectancy, operating hours and function reserve. Increasing amount dirt deposits, sensor misalignment, setting errors or other irregularities can then be reliably detected early by monitoring the emissivity values as a measure of the sensor signal quality. But when it comes to operating security this intelligent sensor offers even more. The BOS 21M ADCAP is the first to optically monitor the output of the emitter LED directly and to determine the "stress level" by means of the sensor interior temperature and the supply voltage.
