User manual CARLO GAVAZZI EM 26 DATASHEET

[. . . ] The indication "EEEE" in a single phase variable automatically implies the overflow condition of the relevant system variable, and the PF indication is forced to "0. 1) according to table 3; To display and scroll the measurement pages relevant to the meters, the "dmd" and system values, the joystick is to be moved to direction 2. To display and scroll the current, voltage, single phase, frequency and phase sequence measurement pages, the joystick is to be moved to direction 3. To display and scroll the power and phase displacement measurement pages, the joystick is to be moved to direction 4. [. . . ] Bianca e lampeggiante bianca/blu in caso di allarme, only once from the switching on of the instrument). If the page relevant to the current position of the knob is not availbale for the required application, the instrument will display the first page available according to the list in table 3. N: 3-phase unbalanced with or without neutral; 3P. I: 3-phase balanced with or without neutral 2P: 2-phase; 1P: single phase. 11 diG in 1 / diG in 2 / diG in 3: ("I3" option only) it allows defining the digital inputs function: rEM: for reading the digital input status by means of serial communication; SYnC: dmd calculation synchronisation; tAr: multi-tariff management (see also Tab. 1 (or 2 or 3): it sets the weight of each pulse (from 0. Note: the digital inputs have to be set with different modes among them, in case they are used for GAS, CoLd o HoT kWh+ Hot. The higher the coefficient, the higher is the stability and the updating time of the measurement. PuLS: pulse output selection (the pulse weight is to be set too) (kWh/kvarh per pulse from 0. In the further menu program the simulated power value (kW or kvar) is corresponding to a pulse frequency proportional to it and based on the "PULSEou. The test is active until you exit from this menu. aL: alarm output (this function is active only in case of application C , E , G and H) , selection of the variable to be controlled (Ph. AL: phase sequence alarm), and deactivation setpoints "on AL" and "off AL", the delay on activation "t dEL" and the output status in normal condition, "nE" if normally energised or "nd" if normally de-energised, are to be set too). DiG in 1 diG in 2 off off on on off on off on Termination of the serial port is to be carried out only on [4]- 3-ph, 3-wire, unbalanced load, 3-CT and 2 VT conthe last instrument of the network by connecting togethnection. 1 [7]- 3-ph, 3-wire, balanced load, 1-CT connection [2]- 3 fasi, 4 fili, carico squilibrato, connessione da 3 TA (for the voltmeter input, a 2-wire connection can be used e 3 TV [3]- 3 fasi, 3 fili, carico squilibrato, connessione da 3 TA by connecting only terminals 15 and 17). E 2 TV Outputs Selezione sistema, tipo: 2P [14]- Relay outputs [9]- 2 fasi, 3 fili, connessione da 2 TA [15]- Open collector output (GND reference) [10]- 2 fasi, 3 fili, connessione da 2 TA e 2 TV [16]- Open collector ouput (VDC reference) Selezione sistema, tipo: 1P The value of the load resistance (Rc) must make the [11]- 1 fase, 2 fili, connessione da 1 TA close-contact current be lower than 100mA; the VDC [12]- 1 fase, 2 fili, connessione da 1 TA e 1 TV voltage must be lower than or equal to 30 VDC. If the instrument is used in a manner not specified by the producer, the protection provided by the instrument may be impaired. Maintenance: make sure that the connections are correctly carried out in order to avoid any malfunctioning or damage to the instrument. To keep the instrument clean, use a slightly damp cloth; do not use any abrasives or solvents. Active Energy: Class 1 according to EN62053-21 and Class B according to EN50470-3. Energy additional errors: influence quantities according to EN62053-21, EN62053-23. Overload status: EEEE indication when the value being measured is exceeding the "Continuous inputs overload" (maximum measurement capacity). [. . . ] Displaying: up to 3 variables per page, 8 different set of variables available, according to the application being selected. Alarm highlight: in case of alarm and if the relevant function is enabled, the display changes the colour alternatively from white backlight to blue backlight and vice versa. Reset: by means of the front joystick: dmd and max. Easy connection function: for all the display selections, both energy and power measurements are independent from the current direction: the displayed energy is always "imported" (with the only exception of "E", "F" and "H" types, for those selections the energies can be either "imported" or "exported" depending on the current direction).
