Installation Instructions Mounting the device on the top hat rail The econ sens + energy consumption meter was designed for mounting on a top hat rail. The device is attached at an angle to the top hat rail with the upper retaining lug and locked into place with light downward pressure (see Fig. 5).
Safety Instructions and Warranty Terms 7 The econ sens+ energy consumption meter can be used with various public power supplies: 3-phase four-wire power system (with neutral conductor) 3-phase three-wire power system (without neutral conductor) Single-phase power system Fig. 7 shows the integration of the econ sens + into a 3-phase 4-wire power system.
Safety Instructions and Warranty Terms 8 If several econ sens+ devices are installed next to one another it is recommended that you use a clamping unit with series terminals. As a result it is easier to direct the fused voltage path in parallel to all devices. Table 1 shows the terminal assignment of the voltage path terminals for the various types of power system. Table 1: Connection diagrams of various power system topologies Manual econ sens+ Version 1.
Safety Instructions and Warranty Terms 9 Installing the econ sens + in a 690V grid The econ sens + can also be used in a 690 V grid (IT-System). It should be noted that a neutral conductor is required. This is because the power supply of this device is itself designed for voltages on the primary side to 440Vrms. When connected to a 690 V power connection so the image has to be used according to Fig. 8.
Safety Instructions and Warranty Terms 10 Alignment of the coil with the current flow If possible, secure the coil round the conductor (cable, conductor rail, etc.) with a tie wrap. Make sure that the loss angle of the coil is not too large (see Fig. 10). In the case of loss angles > +/-5°, the relative error of measurement is also greater and consequently also the relative deviation of the measured current and the calculated parameters (e.g. power).
Safety Instructions and Warranty Terms 11 Connecting the data outputs S0-Interface The consumption data measured by the econ sens+ is outputted via the pulse outputs Imp+ and Imp(open-collector NPN outputs) as a pulse sequence. Each output pulse is 50 ms long and corresponds to a defined amount of energy in Wh. This can be configured via the web interface. (For details see “Web Interface” chapter). The default value for this pulse weighting is 10 Wh/pulse, which corresponds to an output of 100 pulses/kWh.
Safety Instructions and Warranty Terms 12 RS485-Interface The econ sens + supported on this interface the following protocols: Modbus RTU Modbus RTU Via the RS485 Modbus RTU protocol, the values "Modbus / pulses / s submenu " p.17 ff) can be retrieved according to section. To use Modbus RTU a Modbus master is required. In a segment of up to 32 devices can be connected together. For more than 32 devices in a segment repeaters are required.

Safety Instructions and Warranty Terms 16 Meter menu Econ sens+ displays the measured values in tabular form in the Meter menu. This table is shown in Fig. 17. * Figure 13: econ sens+ table of measured values The following are displayed: the voltages of the phases L1, L2, L3, the corresponding currents, as well as the active and the reactive power per phase and the “power factor” (for pure sinusoidal alternating currents, this is synonymous with the familiar cos phi).
Safety Instructions and Warranty Terms 17 You can also have the voltage and the current on the three phases displayed as a curve by selecting the Curve option at the bottom left of the screen. (see Fig.18) Figure 18: Current and voltage curves Econ sens+ is able to measure and display both the generated and the consumed active power. This is illustrated in Fig.12. The consumed active power is shown in the table in blue, while the generated active power with a negative sign is shown in red.
Safety Instructions and Warranty Terms 18 Installation check routine „Installation check“ The econ sens + has a small installation check routine, called "installation check". General, it is measurement assumed coils that were all installed correctly, and the measured load has a power factor of >0.71 (phase shift between U and I <45 °). Then the table of measurements in Figure 20 is shown. In this example, a load of about 6 kW measured at L1, L2 and L3 are unloaded.
Safety Instructions and Warranty Terms 19 Note: Due to the simplicity of the installation check routine, there are also cases where there are no installation errors, the routine but still displays an error message such as: a) The measured power is exclusively produced and there is a little or no consumed power b) The power factor of the connected load is actually <0,71 Therefore, always be careful to correct installation of the measuring coils and their assignment to the voltage path to avoid misunders
Safety Instructions and Warranty Terms 20 Graph menu In the Graph menu, the measurement results are represented as a measuring curve. Fig. 22 shows an example of such a curve. Figure 14: Measuring curve in Graph menu The sum of the power/energy from the three phases is shown over a certain period of time. Using the – period and + period buttons next to the X-axis label you can toggle through the measuring curves step by step (e.g. every day of a month).

Check that the voltages are applied to the device and that the phases L1, L2 and L3 are correctly connected. 3.
Safety Instructions and Warranty Terms 41 Troubleshooting 1.) The S0 outputs of the Econ Sens + supply no pulses Possible causes: a.) The pulse weighting in the Pulses/s menu is set to 0 Wh/pulse -> Set the pulse weighting to > 0 Wh/pulse b.) The pulse weighting in the Pulses/s menu is set too high -> The pulse outputs of the econ sens+ allow for a maximum pulse rate of 10 Hz. Lower the pulse rate to a lower value. How to calculate the maximum admissible pulse rate is explained in the chapter Pulses/s.
Safety Instructions and Warranty Terms 42 e.) The coils for current measurement are wrongly aligned (label does not point in direction of load) -> econ sens + is able to measure both generated and consumed power/energy. The econ sens + has one pulse output for consumed power and one for generated energy. Imp+ = consumed power Imp- = generated power Only the Imp+ output is of significance for the measurement of pure energy consumption.
