TEST ACCESSORIES FROM ETL – EVERYTHING FROM ONE SOURCE

Fully electronic testing system

Precise test voltages and currents for reproducible and wear-free testing. All test parameters are continuously regulated and independent of any mains voltage fluctuations due to full electronic generation.

Safety circuit with two force-guided safety relays (TÜV certified)

The safety technology is implemented as required by EN 50191. There are 9 different wiring options available to test in compliance with standards using test guns, test cages, two-hand operation, or within a transfer line.

Menu-driven test sequences: Manual or fully automatic

The user can choose between individual testing of available test modules or testing with a predefined, freely configurable test plan. Testing via a test plan runs reproducibly in production, supporting test personnel with clear status and error messages.

Connection of test tasks is automated through an internal relay matrix

The test object only needs to be plugged in or contacted once. Switching between different test tasks is automated and realized through an internal relay matrix.

Operator instructions and digital photos

Various instructions and digital photos can be displayed before and during testing, as well as in case of an error, to guide the tester optimally through the process.

Start automation

The start signal is triggered by pressing the test guns (patented). Voltage is only applied when both test probes are securely in contact with the test object. This protects the test object from overvoltage peaks and ensures the required test time (functionality depends on the chosen test modes).

Monitoring of test lines for conductor breakage and monitoring of contact with the test object

High-voltage lines are implemented in 4-wire technology (patented) to achieve maximum process safety (functionality depends on the installed test modules).

Shutdown via Limit Detection, Arc Detection, and Peak Detection

Multiple criteria are available to reliably detect insulation faults. In addition to exceeding the current limit, the activation of a specific overcurrent detection also leads to an error. This ensures the reliable detection of low-energy breakdowns.

Ramp function and detection of breakdown voltage in high-voltage tests

The voltage ramp is switchable, and parameters (such as rise and fall time) are freely selectable. The ramp function ensures a particularly gentle test and is mandatory when a product standard prescribes a specific voltage profile. Additionally, the voltage value at which an error was detected is recorded.

All test tasks are individually configurable 

All parameters such as test voltages, test currents, limits, test times, start options, operator instructions, matrix settings, sequence options, and the test order are freely configurable.

Individual settings for

Language settings, user management, memory options, behavior of digital inputs and outputs, acoustic signaling of status and error conditions, options for contact and cable break monitoring, file manager for test plans and result files, and much more.

Testing device for “stand-alone operation” or remote control via interfaces

The testing device can be remotely controlled via PC software (ETL DataView user interface), custom applications (DLL, .NET), simple command parameters (ASCII), or digitally from an SPS (Digital-IO).

CAN interface for connecting external expansion modules

The testing system offers the possibility to connect external modules and measurement tasks via an ETL CAN interface. The system can be expanded with a matrix for replicating test points, 1- and 3-phase power sources for functional testing, or even a hot HV test under mains voltage conditions.

Error notification: Acoustic, visual, and via interface

Faulty test objects can be reliably detected. In addition, the type of error is displayed and documented in the result file.

Upgradeable via interface and remote maintenance

Customer-specific changes and updates can be applied via the interface, and for PC-based systems (X6 or X8), remote maintenance is possible through Teamviewer.
