    Introduction 1.2.2 General safety instructions Be careful touching the DTI375 device during operation. The DTI375 may warm up to temperatures causing inju- ry to persons touching it (warming-up phase can be less than 1 hour). Avoid covering the DTI375 device with insulating materi- al during operation. The DTI375 device may warm up to temperatures causing possible burning of the insulation material (warming-up phase can be less than 1 hour).
  • Page 9: Protection Rating

    Data recorder Type DTI375 In order to prevent equipment damage when using the DTI375 system components with long cable, the system should not be used in case of lightning during storm. Any interconnection cables longer than 30 m or exiting the test building shall be disconnected to prevent possible dama- ge caused by indirect lightning effects.

  • Page 11 Data recorder Type DTI375 Each DTI port has an individual RS-485 transceiver for the data transfer on the bus. This setup is very secure against interferences and emits only very low interferen- ces itself, which means that the achieved signal quality is better than conventional analog technology.

    Fig. 7 (left side) shows how to disconnect the UPS from the Type DTI375.12 connector, respectively from the Type DTI375.08 connector (Fig. 7, right side). First unbolt the two TX8 M2.5x10 screws (1). Pull the UPS connector up a little in the direction as shown in Fig. 7 (2). Then the connector can be lifted up (3) and disconnected from the Type DTI375.01 UPS.

  • Page 20: Power Save Mode

    Installation and operation The DTI ports 1 ... 6 (1 ... 4 for Type DTI375.08) are pre- sent on Lemo connector A, ports 6 ... 12 (5 ... 8 for Type DTI375.08) at Lemo connector B. Each DTI port of the data recorder has its own short cir- cuit-protected regulator for the power supply to the DiMod modules (including sensor system) connected to the DTI bus and can provide a maximum of 500 mA. To ensure that the maximum voltage drop of 0.5 V on the DTI cable is not exceeded, the cable length must be limited accor- ding to its cross-section.
  • Page 21 Data recorder Type DTI375 In case of test execution interruption, it might happen that the recorder is powered but idle for a long time. In order to minimize the heating of the dummy during idle times, the Type DTI375.01 UPS which is attached to the Type DTI375 recorder is equipped with a Power Save Mode for reducing the power consumption of the Type DTI375 by more than 80 %.

    Installation and operation intervals. Therefore the latency for recovering a DTI375 recorder from Power Save Mode depends on the configu- red power down time. The average power consumption of the DTI375 recorder in this mode can be estimated as follows: 10 �������� �������� × 1.5 �������� + 0.3 �������� ��������...

    Installation and operation 2.3.3 Synchronization The DTI375 data recorder supports an optional 1 kHz in- put clock for synchronization with all of the systems in the crash test, including the high-speed cameras. The syn- chronization signal is in RS-485 format for reasons of in- terference.

    Data recorder Type DTI375 2.3.4 Trigger features 2.3.4.1 Digital trigger T0 and SR The DTI375 recorder has two digital trigger signals (T0 and SR) each connected through the main system con- nector using an RS-485 bus. The signal can be generated by an RS-422 or RS-485 dri- ver. The idle state (no trigger) of trigger lines is T0+ at ap- proximately 0 V and T0–...
  • Page 26: Trigger Modus

    Installation and operation 2.3.5 Trigger modus In this chapter you will learn about ring buffer mode (also called "transient mode") and recorder mode. The modes do not have to be explicitly selected, but rather depend on the usage of the two trigger signals SR and T0. By default the DTI375 recorder will always run in ring buffer mode which behaves like a DTI304 series recorder.
  • Page 27: Recorder Mode

    Data recorder Type DTI375 If the trigger signal at time T0 fails for any reason, impor- tant measurement data could be overwritten, if the recor- der is not stopped manually in time. In order to minimize this risk, the recorder mode should be used which requi- res two trigger events but it will prevent overwriting any measurement data even if the trigger signal of the impact fails.
  • Page 28: How To Estimate The Acquisition Time

    Installation and operation You may use the recorder mode if you are sure that after starting the acquisition, your trigger event (for example: impact) will lie in the span of the post-trigger time. See chapter 2.4. After arming the recorder, measurement data is conti- nuously written into the flash memory (ring buffer) while waiting for the first trigger event start record (SR in Fig.
  • Page 29 Data recorder Type DTI375 Thus, the total recording time depends on the amount of measured channels. Please keep in mind that 1 system channel is always switched on. Flash memory can have up to 10 % block errors. These blocks cannot be used for measured data. The DTI375 recorder takes care about these blocks and avoids sto- ring measurement data in them.
