Test Benches

The bench is equipped with a Keyence vision system for checking the correct signal graphic of the trip condition of the engine control lever. 

The engine power is checked by a special electronic card. 

To check the closing and opening times on 4 and 9 channels, special fast inputs will be set up on the PLC. 

The bench is managed by an ASUS touch screen PC with HMI function, which hosts a software internally developed that allows the following functions:

• Data interchange with company network.
• Serial number scan with BARcode and QRcode reader.
• Acquisition of test parameters.
• Recording of test results on Excel file.
• Creation and eventual exportation of a .CSV file for each serial number, showing the results of the tests.

The bench is equipped with a generator for powering the motor controls, capable of supplying voltages between 15 and 30 Vdc with a power of 1600 VA.

The bench is equipped with 2 static current generators that feature three scales 2 A - 12 A - 60 A to perform thermal tests on relays and motor protectors.

Management software features:

•  Management of test types (recipes)
• Setting of test currents and test duration outside the recipes
• Setting the number of test cycles
• Storage of the following data in a  database: product code, batch number, test date, operator name, intervention times of NC-NO contacts, contact switching delay, reset times,  currents applied
• Exportation of data  in CSV format

Test bench for thermal test on relays

The bench is equipped with a current generator equipped with a voltage drop measurement system. This measure is managed by the management software.

Test bench for testing differential relays

The bench is equipped with a single-phase current generator and an isolation transformer for powering the differential. The integrated management software was developed according to customer specifications.

Test bench for molded-case and air circuit-breakers accessories, equipped with 3 voltage power supplies and 3 current generators.

The test bench is equipped with an electric control panel, on whose door it has been positioned a panel with LEDs  for checking the status of the auxiliary contacts. On the the panel are also installed 60 spring clamps for connecting terminals of the accessories.

Climatic Chamber with single-phase corrent generator for testing circuit breakers.

Software functionalities:

• Setting the primary test current directly or gradually

• Setting unbalanced phases current

• Setting number of cycles

• Settting internal temperature directly or gradually

• Setting the fan speed

• Storing and exporting test data 

• Visualizing alarms

The bench allows you to perform dielectric rigidity tests in a functional and safe way.

The machine performs the following types of tests:

• Check the tightening torque of the screws; 
• verification of the electrical continuity of the circuits;
• dielectric strength check;
• verification of counter functionality;
• verification of correct voltmetric socket connection;
• verification of power supply wiring and operation.

The bench performs functionality tests of the residual current releases, both loose and coupled with the respective circuit-breakers. In addition, the equipmemnt  tests the remote controls coupled with the circuit-breakers.

The bench is also able to test undervoltage, opening and closing coils, both AC and DC.

The test bench performs weighing checks with the application of labels. The equipment has a supporting structure made of robust metallic carpentry. 

All the devices are inserted and fixed on special shelves: the Mettler Toledo model scale, complete with relative  position for the storage of the tank; bar code reader; Zebra ZT 230 label printer. The PLC management software is set up for management supervision connection.

The bench performs the short reliability test on relays used in the automotive sector. It is structured to perform both mechanical durability tests with low load current (10mA max) but with high cycling frequency, which tests with high electrical load (50A max) and with low cycling frequency.
