  • Page 4: Product Description

    Product description This operating manual describes all design variants of the EM4TII+. Be aware that meters may be designed differently with regard to configuration, interface, inputs/outputs etc. It is possible that some meter characteristics are described here which do not apply to your meter. The EM4TII+ is a single-phase energy meter as per EN 50463-x:2017 and thus meets the requirements of the EU directive 1302/2014/EU in accordance to Commission Implementing Regulation (EU) 2018/868 and 2019/776.
  • Page 5 The supply voltage for the EM4TII+ can be selected between 24 V and 110 V as per EN 50155. Two hardware variants are available, one for 24V or 48V, the other one for 72V, 96V or 110V Optionally a communication unit (modem) can be supplied with 12V DC voltage from the EM4TII+. The conditions of use (with regard to EMC, temperature, vibrations etc.) meet the special requirements for locomotives, including the EN 50155, EN 50121-3-2, EN 50124-1 and EN 61373.

  • Page 8 DANGER! Contact of parts under voltage is extremely dangerous! When installing or changing the meter, the conductors to which the meter is connected must be free of voltage. • Remove the relevant back-up fuses and store them in such a way that other people cannot re-insert the back-up fuses without notice.

  • Page 9: Electrical Connection

    Electrical connection DANGER! Contact of parts under voltage is extremely dangerous! • Secure meters with a transformer connection in the voltage path with a back-up fuse of <6 A. The supply lines to the device - which can total up to nine depending on the energy meter design - must be laid with cable glands and connected as per figure 3.2.

  • Page 25: Recognition Of The Traction Power System

    4.2.7 Recognition of the traction power system The EM4TII+ recognizes the currently applied traction power system. A traction power system is in this sense always understood as a combination of the supply frequency (DC or AC-frequency) and the supply voltage. Rated voltage values (according to EN 50163:2004) of 600V/750V (DC), 1500V (DC), 3000V (DC), 15.000V (16.7 Hz AC), and 25.000V (50Hz AC) can be distinguished.

  • Page 26: Error Register (F.f)

    On the display of the EM4TII+ a flag signalizes the current supply frequency (DC, 16.7 Hz, 50 Hz or 60 Hz) in the case of a detected traction system. Furthermore, in the billing load profile and in the logbook of EM4TII+ any change of the traction system is stored with the seconds-accurate timestamp.

  • Page 30: Maintenance

    Maintenance The meter is maintenance-free. With damages (e.g. caused by transportation or storage) no repairs may be carried out. Once the meter has been opened, all warranty claims cease. This also applies if a defect can be traced back to external influences (e.g. fire, extreme temperature- and weather conditions, incorrect or careless use or treatment).

  • Page 31: Measurement

    Measurement Measuring principle The load profiles are recorded in datasets at parameterized intervals. The measuring circuit comprises a Sigma Delta ADC for each measuring channel which enables simultaneous capturing of measured values at a sample rate of 4800 Hz. The Sigma Delta method effectively suppresses high-frequency interference on the channels.
