Test station with automatic protection using RFID sensor safety module S 2109

End-of-line safety testing in production

Test stations built with enclosures, such as test cages or hoods, are the most commonly implemented option. This type of test station is typical in serial production lines, but is also preferred in workshops, repair, and service shops. Test stations with automatic protection against direct contact may be operated without the control and supervision of a skilled person. The safety system in a test cabinet provides automatic protection against direct contact as the testing sequence can only be started when the doors are securely closed. The ‘cage closed’ sensor is RFID coded, therefore malfunction or misuse is practically impossible.

IEC 60335-1 is one of the most widely recognized standards in the field of testing electrical equipment in production lines. Annex A of the IEC 60335-1 specifies that routine tests are to be carried out by the manufacturer on each appliance to detect production variations that could impair safety. They are normally carried out on the completed appliance after assembly, but the manufacturer may perform the tests at an appropriate stage during production, provided that later manufacturing processes do not affect the results.

The following tests are the minimum considered necessary to cover essential safety aspects. It is the manufacturer’s responsibility to decide if additional routine tests are necessary. It may be determined from engineering considerations that some of the tests are impracticable or inappropriate and therefore need not be carried out.

  • Earth continuity test
  • Dielectric strength test
  • Functional test

Measurements

MI 3394 XS (Extra Safety) is a specialised test instrument designed for integration into production lines. The instrument permits the connection of different safety sets for independent control of dangerous measuring circuits. It also supports user-created test sequences with comments, images, wiring diagrams, and other extra content.

The parameters and limits can be varied for all tests. The instrument can be remotely controlled via black-box protocol, which makes it ideal for integration into automated test systems.

Main features of the instrument:

  • All features of MI 3394 CE MultiTesterXA.
  • Control of measurement circuits with help of Safety sets.
  • Perfectly suited for use in workplaces conforming to EN 50191.

MI 3394 CE MultiTesterXS

A 1600 CE Switch 5kV

Accessory description:
The A 1600 CE Switch 5kV combines all features of the CE MultiTesterXS and extends them to four HV test channels and two 4-wire continuity test channels. The CE Switch could be used in conjunction with several separate connection boxes, containing various kinds of contacting to tested items. The operation of CE Switch is completely controlled by the master instrument, no user intervention during the tests is needed. I/O connections and LEDs for controlling the Autosequence® flow are integrated. Testing of electrical equipment with multiple connection points is supported. The switch recognizes the connected adapter and prevents from applying too high voltages/current to it (protection by HW and SW).

A 1650 Single chamber test cage

Accessory description:
The A 1650 Single chamber test cages provides automatic protection against direct contact. Its construction is designed “ready” for integration of RFID safety module. The safety module’s “coded” RFID sensor is monitoring the “cage closed” position, this enables the test system to prevent touching of the DUT throughout the test sequence where dangerous voltages can occur. Passive tests can be normally generated also at opened doors. Malfunction or misuse is practically impossible.

S 2109 Safety system with RFID sensor

Accessory description:
This Safety module is designed for test places where protective cover or safety door is used. The module is intended for protection with an RFID sensor and emergency switch. The RFID switch indicates the state (opened/ closed) of the door of the cage or cabinet. If the door is opened the safety module will disconnect the measuring circuits from the mains, which results in the maximal protection for the operator. The safety module is equipped also with the emergency switch and the START button.

A 1626 Connection box 1-phase

Accessory description:
Diversity of electronic products, which need to be tested, present a many challenges for the manufacturers. Different sizes, shapes and configurations of electronic devices make it challenging for electrical safety examination. Due to these facts Metrel has developed different types of connection boxes, which can be easily adopted to customer’s needs. The A 1626 connection box is a passive devices that acts as a connection interface between the CE SWITCH and the tested equipment. It is intended for connection of various 1-phase appliances to A 1600 CE SWITCH. Equipment with supply cord, equipment intended for fixed installation, electronic subassemblies can be tested. Connections for connection to isolated conductive parts and earthed parts are added. The connection box is coded in order to prevent from applying a too high test voltage to its outputs.
