ESD Simulator

Electrostatic discharges either from a human body to any other
part or between two different objects can cause persistent dis-
turbances or even destruction to sensitive electronics or con-
trols. esd NX30 is an ESD tester to simulate ESD pulses at
higher voltages up to 30 kV in both air and contact discharge
mode. It therefore satisfiers requirements exceeding the
EN/IEC 61000-4-2 test levels and complies to automotive test
applications

    NX30 EM Test EXPLANATION OF THE SYMBOLS USED IN THIS MANUAL Please take note of the following explanations of the symbols used in order to achieve the optimum benefit from this manual and to ensure safety during operation of the equipment.

  • Page 5: Safety

    WARNING The esd NX30 simulator is not a toy! It is a professional tool and belongs only in the hands of specialists and appropriately trained personnel. When powered by its own batteries the generator can be active even without any power cable being connected.

  • Page 6: Introduction

    Such tests provide valuable information about the immunity of the system to effects that occur only sporadically under operating conditions and hence represent difficult to detect sources of disruption. The ESD simulator esd NX30 fulfils the requirements of numerous applications in an ideal manner, thus: Ergonomic shape: For non-tiring use.

  • Page 7: Effects On The Eut

    ESD (electrostatic discharge) testing usually shows up all the weak spots in the HF-range of a piece of equipment simulta- neously. The uses to which the esd NX30 ESD simulator can be put hence go way beyond those called for in standard- conform applications.

  • Page 8: The Esd Nx30 System

    The esd NX30 offers optimal freedom of movement around the work-place and is an ideal test instrument not just for the development engineer but also for quality control purposes, system tests and for investigations in the field.

  • Page 9: Function Modules

    NX30 EM Test 4.1.1 Function modules The base station contains the battery supply, the high voltage generator and regulator as well as several safety features. The pistol houses the interchangeable pulse network, high voltage relay, the exchangeable discharge tip, measuring elec- tronics and the touch sensitive input / display panel.

  • Page 10: Operating Elements

    The esd NX30 is switched on and off with the main power switch. The significance of the elements in the display field can be seen in the following picture. Further information can be found in section "Operation".

  • Page 11: Battery Charger / Power Supply Unit

    Battery life expectancy (esd NX30 only): • The esd NX30 is designed to provide 30,000 discharges at the full 30 kV over many hours • Ambient temperatures over 50°C can lead to degradation of the battery. If treated carefully, more than 300 charge / discharge cycles can be expected without a noticeable reduction in capacity.

  • Page 12: Remote Triggering (Esd Nx30 Only)

    Remote triggering (esd NX30 only) This port is indented to allow the user to connect external signals in order to remote control the esd NX30 generator, as well as to connect external accessories like the charge removing device. See tables and graphs below for detailed signal descrip- tion and drive circuitry information.

  • Page 13: Interlock (Esd Nx30 Only)

    2. Internal emergency off button opens the interlock. Outputs 1. Operating mode: the esd NX30 can generate no high voltage as long as the interlock is not closed. High voltage genera- tion is prevented if the interlock is opened during a test procedure.
  • Page 14 NX30 EM Test S: External safety switch (e.g. test enclosure hood, door contact, panic button, etc...) Several interlock inputs of this type may be connected in series. The contacts should be connected in series if numerous access barriers are necessary. Either one open contact or a voltage of more than 1.5 V at the input is sufficient to disable the simulator.

  • Page 15: Commissioning

    Plug the interlock terminators into the base station, if equipped • Connect the earth cable correctly (the esd NX30 must never be switched on without a solid earth connection being made). • Allow the instrument to dry out if any condensation has occurred Function test Switch the simulator on with the POWER switch.

  • Page 16: Operation

    EM Test OPERATION This section of the manual provides a guide through the numerous operating possibilities of the esd NX30. The operation, hierarchically arranged, is therefore easy to remember. The display shows unmistakable information about the parameters that have been set and the operating status of the simulator.

  • Page 17: Display Mode

    NX30 EM Test 6.3.1 Display mode When adjusting some parameters, a keyboard and up / down buttons can be selected. Numerical values (voltage, preset counter, random repetition times) can be entered just the same as with a pocket calcula- tor.

  • Page 18: Counter

    NX30 EM Test 6.3.4 Counter Use the counter button to branch into the corresponding menu. Choose the counter mode: Preset counter on / off. In the On state the counter content can be set. When the simulator is in operation the preset counter counts down until it reaches 0, which then terminates the selected test sequence.

  • Page 19: Repetition

    NX30 EM Test 6.3.5 Repetition The repetition button takes you into the menu to select either single pulses or a repetition rate from 0.5 to 25 Hz in air dis- charge, or from 0.5 to 20 Hz in contact discharge mode.
  • Page 20 EM Test EUT discharge on esd NX30/NX30.1: To remove the charged energy of a EUT, the simulator has an switch. With the time of the charge removing procedure can be programmed. All timing parameters can be set from 0.1 up to 99 s in 0.1 s steps.

  • Page 21: Settings

    The Log is in volatile RAM and will be saved each time the gun is switched off or goes to sleep. Please switch off the gun properly, simply cutting the power to the esd NX30 can result in loss of data.
  • Page 22 NX30 EM Test Only users of esd.control can set the Last Cal and certificate number. For best results, be sure to use an au- thorized AMETEK CTS calibration laboratory. NOTE Instruction Manual V 1.00.7 22 / 33...

  • Page 23: Threshold

    If somehow the maximum voltage could not be reached or hold, the esd NX30 comes out with an error message Nr. 210 cal. Failed. The calibration procedure is diagnosing, to which voltage level the instrument works properly. This voltage value will be shown on screen.

  • Page 24: Continuous Operation

    NX30 EM Test 6.3.16 Continuous operation Continuous operation can be established to produce a repetitive stream of discharges. Pushing the trigger button starts the continuous operation; pressing it again stops the operation. Continuous operation should only be utilized in cases of real necessity since every ESD radiates electro- magnetic disturbance the effect of which on the environment must be taken into consideration.

    EUT itself and the documentation. Standard-compliant procedures The ESD simulator system type esd NX30 is constructed in accordance with the requirements called for in the standard and is calibrated in a standard-conform manner. The test engineer is duty-bound to study the relevant test requirements and adapt the facilities to suit the EUT in question.
