  • Page 4: Introduction

    1 Introduction The device acts as a power meter. It has a built-in meter for measuring the following electric values and sending them on the BUS: active energy consumed and produced, active/reactive/apparent power, RMS voltage, RMS current, power frequency and factor.
  • Page 5: "Information" Menu

    3 "Information” menu The Information menu reminds the user, in operating terms, how to access the PROG menu in order to activate the programming mode of the physical or individual address of the device, and how to return from this menu to the RUN menu (long press on the UP and DOWN push-buttons).
  • Page 6: "Energy Meter Settings" Menu

    4 “Energy meter settings” menu The Energy meter settings menu contains just one parameter for configuring the transmission of telegrams on the BUS following a BUS voltage failure and reset, to avoid a surge in messages and the risk of them colliding.
  • Page 7 If the values 11..21 seconds (depends on physical address) and 5..9 seconds (depends on physical address) are set, the device automatically calculates the transmission delay using an algorithm that examines the physical address of the device itself; the values indicated (11/21 or 5/9) indicate the minimum and maximum limits of the value range that can be calculated.
  • Page 8: "Electric Measures" Menu

    5 “Electric measures” menu The Electric measures menu contains the parameters for enabling and setting the conditions for sending the electric measurements detected for the load connected to the device. This menu is always visible. The structure of the menu is as follows: Fig.

    For all the thresholds selected, the configuration menus of the parameters (and the corresponding objects) relating to each one will appear. The Power threshold x enable (Data Point Type:1.002 DPT_Bool) and Power threshold x enable status (Data Point Type:1.003 DPT_Enable) communication objects are used respectively to receive the threshold activation commands and send the signals regarding the threshold activation status;...

  • Page 24: Changing Threshold Setting

    Note that, in the case of a negative threshold value, the limit is considered “exceeded” when the measured power value is lower than the “Limit threshold” value; when the power value rises below the “Limit threshold - hysteresis” value, the limit is considered “not exceeded”. If this rule is not respected after ETS download, the default values are used.

When an overflow occurs, a value of “1” is sent; a value of “0” is sent when the counter is reinitialised. The device can use the Reset Number counter over power threshold x (Data Point Type: 1.015 DPT_Reset) communication object to receive the counter reinitialisation command that brings the count back to its initial value of 0.

    Note that the same message - “Pr.L On” - that indicates the activation of the physical address programming mode also appears on the display when the mode is activated via the BUS with a specific telegram sent by the ETS application (device LED - ON). In the same way (and in keeping with normal manual management), the deactivation of the mode via the BUS (device LED - OFF) will take you back to the previous message - “Pr.L OFF”...
