The performance potential of the MTC3 test systems is based on the interplay of all strengths: user-friendliness, measurement accuracy, memory concept – all components are perfectly coordinated based on innovative technologies.

As one of the first test equipment manufacturers, SCHLEICH consistently relied on the integration of a PC for measurement value processing, test sequence control and data storage for MTC3 test systems at an early stage. This many years of system experience of our technicians and engineers provides the operator with a sophisticated test system with extensive software. Many useful software tools are part of our standard scope of delivery.

Our fully automatic MTC3 test systems reliably and quickly Test your windings for potential insulation faults thanks to the patented SCHLEICH surge test. After the device under test is fully connected, the Test proceeds with automatic switch-over of Connections and test methods. The MTC3 evaluates each individual specified test step. At the end of the entire test sequence, a clear and reproducible GO or NO-GO result is provided.

SCHLEICH develops and produces its own hardware and software. The software and memory are based on the latest proven Microsoft^® technology. Our diverse innovations consistently set technological standards for modern test systems running on Windows^®. The system provides the operator with a clear, well-structured display of the test – while extensive input and configuration options are available to the setup technician.

Quality assurance is also given due attention. For this purpose, comprehensive statistical evaluation is built-in to the test system, leaving virtually no wishes unfulfilled. Furthermore, you can document the tested quality for your customers with a variety of different protocol printouts.

The MTC3 test systems are manufactured according to your requirements based on the SCHLEICH MODULAR CONCEPT. The necessary different test methods can be assembled as needed from the pool of available test methods.

Whether manual or automatic single, double, or multiple stations – with or without a test cover or test table – or testing in automatic production lines, the MTC3 is the optimal solution. The application versatility of the MTC3 is limitless. Precisely due to the enormous flexibility of its hardware and software, the test system is cost-effectively and precisely tailored to your specific tasks.

The MTC3 is available in various standard configurations. The compilation is carried out according to the desired application.

Starting from the base device with standard equipment, you determine the number of required winding Connections and temperature sensors. You select additional test methods from the available pool.

Should no suitable solution for your application be listed here, we will gladly put together a custom solution for you based on the SCHLEICH MODULAR CONCEPT. More is always possible!

Based on the SCHLEICH MODULAR CONCEPT, the MTC3 test systems provide a variety of combination options for diverse safety and functional test methods. Your custom test task determines the test methods you select from a large pool of testing possibilities.

Whether one test method or a multitude – you determine the configuration! For example, your MTC3 can be configured as a specialized high voltage test device with many test outputs. For more complex test tasks, you might need a combination of all possible test methods.

The SCHLEICH MODULAR CONCEPT makes it possible to assemble exactly the test device you need. And not just by installing various individual test devices into an oversized test rack, but by integrating all tests into a compact modular housing. The housing size results from the type and scope of the various tests.

The flexibility of the MTC3 test systems is evident not only in the housing but also in the number and arrangement of the test device's Connections. With the 19" container and the 19" industrial cabinet, the measurement connections can be attached to all sides of the test device. This allows us to meet all spatial requirements.

Every test device incorporates experience from many thousands of installations. This experience is consistently implemented at SCHLEICH, with passion and without compromise.

This is “customer based technology”.

The test devices provide a variety of test options in just one housing, despite their very compact design. The combination of test methods according to the SCHLEICH MODULAR CONCEPT therefore also includes a modular housing concept.

Depending on the requirement, your application can be housed in a compact desktop device, a 19” rack-mount device, a 19” container, or a 19” industrial cabinet. For the professional and secure installation of the test technology, we use precisely fitting housing components from renowned German manufacturers as well as components from our own production.

The software is based on the Microsoft Windows^® operating system. The optimized user interface enables user-friendly test execution, test plan creation, printing of test protocols, and statistical evaluation of tests.

In automatic mode, all tests are run fully automatically. Measurement results are continuously displayed and evaluated during the test. The clear GO/NO-GO display visualizes the automatic evaluation.

The test sequence is processed by simply adding or removing test steps. This allows the test sequence to be optimally adapted to different requirements. Each individual test step can be quickly edited and modified by double-clicking on the respective test step.

The comprehensive built-in operator management ensures that only authorized personnel can make these changes. Additional work instructions make the MTC3 the perfect ISO 9001-compliant test equipment.

Test plans and test results can be stored locally or on a central server. This ensures high data security and optimal data exchange between different test systems.

The MTC3 operates optimally in all network infrastructures. This feature provides the ideal platform for collecting, managing, analyzing, and distributing information.

Proven and widely used Microsoft^® technologies are used as memory.

The testing devices can also be ideally networked with ERP, PPS, and CAQ systems. For all requirements, we provide extensively tested and customer-optimized standard solutions.

The Windows^®-based MTC3 testing devices can be operated in arbitrarily complex network topologies. You can install any number of testing devices at various company locations worldwide, all working with a central server memory for test plans and test results. Our extensive experience in the global networking of our testing devices provides you with the assurance of being able to provide the same product quality regardless of the production location.

Naturally, all test plan, printing, labeling, and statistics tasks can also be run on the individual testing devices. However, to avoid disrupting the production process, it is advisable for networked systems to use separate workstations for these tasks. These workstations operate with the same software as the testing devices to achieve the highest possible ease of use.

The label templates can also be stored centrally on a server. The testing device loads the appropriate label according to the respective test plan and transfers the data to a thermal transfer printer after the test. The labels can also be designed according to your specifications.

In the event of remote maintenance (via Remote Access), we can temporarily dial into your network if required and switch directly to the individual testing device. We then see the screen content of your testing device directly at our location. With your permission, we also have access to the mouse and keyboard. These operations are, of course, only carried out in consultation with you and require your separate access authorization.

The MTC3 is ideally suited for integration into automation systems. For this purpose, it offers an enormous variety of different interfaces for communication with various automation systems.

Typical requirements are:

• Control of complete processes and components
  – Processing of inputs, signal generators, scanners, RFID readers …

Traceability provides you with the ability to obtain clear and complete information about the entire manufacturing process, even retrospectively. In the event of quality problems during production or after delivery, traceability offers you the option to respond in a targeted manner.

We provide responses to the following questions:

• Which end products, assemblies, and components are affected?
• Which customers have the end products, assemblies, and components?
• Which assemblies and components are built into the end product?
• When, where, and by whom were which parts processed in the manufacturing process?
• Who manufactured or supplied the assemblies and components?
• Which test results are available for the individual assemblies and the end product?

A prerequisite for the response to these questions is the unique identification of each component, assembly, and final product with a number or code. Additional information such as customer number, supplier number, batch number, etc., may be required for improved traceability and search functionality.

MTC3 test systems are capable of recording these markings and additional information, e.g., via barcode input, and saving them together with the test results, test date, and operator name in the memory of the test device or on the network. Based on this information, it can later be traced where, when, and by whom components were processed or delivered in the manufacturing process.
