  • Page 5: Overview Of Functions

    1 Overview of functions Keys 0 to 9 have more than one function. The current function depends on the operating condition. In normal display mode, the text below the key applies and allows measured values or chapter headings and functions to be directly or indirectly accessed.

  • Page 6: Explanation Of The Most Important Key Functions, Faqs

    2.1 Levels and rights of access The ERZ 2000 system provides three access levels to change parameters or device settings. The lowest level is the user level which is protected by code. It is marked B, C or P in the documentation.

  • Page 7: Fundamentals For Accessing Data

    The <0> Mode key shown in the example above enables central access to the chapter headings. When you press the <0> key, the ERZ 2000 will jump to table E and display the first chapter Base values and the following chapters which can be browsed through using the Cursor Up or Down key. When you browse through the chapters, an arrow →...
  • Page 8 Whenever the device shows a view with a chapter heading, you can access all chapters of the entire system by pressing the Cursor Right or Left key. When you have reached the desired chapter heading, press the Cursor Up or Down key to access the chapter or press Enter to activate the function.

  • Page 9: Entering The User Code

    2.3 Entering the user code The lowest access level is protected by the user code. The code is divided into two 4-character parts and has to be entered in two subsequent coordinates. In the operating instructions, the relevant data are marked Β (for user lock).

  • Page 10: Setting The Device Type

    Follow the above sequence of operations. • Now prepare the ERZ 2000 for the update. Press <0> Mode and in the Access chapter set the Software update function to ON. The ERZ 2000 terminates the correction process and from now on it is only waiting for the software update to start.

  • Page 11: How To Activate The Device Again Following A Software Update

    • After you have opened the calibration lock, press Enter again (the display will turn darker and indicate input mode). The old activation key will disappear and the ERZ 2000 will be waiting for the new key to be entered.

  • Page 16: Special Information About Parameters For Volume At Measurement Conditions

    Operating mode: As to the modes 1 to 9, the notation means: The first parameter applies to billing and the second parameter to comparison. If Vo stands at the beginning, for example, Vm increments are calculated from the telegram contents of the digital totalizer, i.e. the Vm totalizer is calculated from Vo information.
  • Page 17 Creeping quantity limit: The Vm and Vb totalizer readings are not increased as long as the flow rate at measurement conditions is below the creeping quantity limit. The creeping quantity cut-off function prevents uncontrolled counting of pulses e.g. in the case of swinging movements when a turbine meter is at standstill or of pulses at zero drift in the case of other gas meters.

  • Page 18: Logic Of Synchronous Run

    Monitoring of synchronous run (coordinates JK...) There is a chapter Synchronous run monitoring to be found under the <0> Mode key. Here you can find the parameters for monitoring synchronous run, such as the maximum deviation, termination short and termination quantity and information displayed about the current state of the ongoing comparison. Monitoring of synchronous run deals with the software comparison between the possible inputs for volume formation.

    Characteristic The current kv mode is shown. In this example, a polynomial • kv mode defined by RMG is calculated via the flow rate. The point before the kv mode indicates that the value can be edited Polynomial Q RMG (note the access level).

  • Page 20: How Does Error Curve Linearization Function For Volume Measurement

    2.14 How does error curve linearization function for volume measurement? Error curve linearization: The error curve linearization of the gas meter can optionally be performed using two different methods. a) Error curve linearization with polynomial related to the flow rate Correction is made using a quartic polynomial which reproduces the error curve of the gas meter as a function of the flow rate.
  • Page 21 c) Error curve linearization using the interpolation point method This method uses 16 parameterizable interpolation points. The selected loads are to be entered on the X-axis (flow rate). For each interpolation point, the deviation from the zero line is to be entered. A linear interpolation is to be made between the individual points.

  • Page 22: How To Activate Direction Switching

    2.15 How to activate direction switching? Direction switching is integrated into the billing mode. As to the standard setting, billing mode 1 corresponds to direction 1, billing mode 2 to direction 2, etc. There are a total of four billing modes which can be controlled either via input contacts or limiting values.

  • Page 27: Time System

    The internal time basis can be changed via the keyboard or the DSfG interface but only within the scope of the relevant access rights. If there is a telephone connection via MODEM available, the ERZ 2000 can use PTB's time service and synchronize its clock (and that of all users of the bus) with its integrated remote data transmission feature.

  • Page 28: Where To Set Base Values For Pressure And Temperature

    2.21 Where to set base values for pressure and temperature? If the K coefficient is calculated in accordance with GERG 88S or AGA NX 19 with H group gas, the temperature at base conditions can only be changed step by step according to the ISO table of countries (0, 15, 20, 25 degrees C).

  • Page 29: Special Information About Test Functions
