Only calibrated meters are approved for electricity accounting according to §25 of the German calibration law. Non-compliance is an administrative offense according to §19. RS485-Bus radio three-phase meter. Maximum current 3x80A, standby loss only 0.8 watts at L1 and 0.5 watts at L2 and L3 each. Accuracy class B (1%). With RS485 interface. The direct measuring three-phase meter measures the active energy based on the currents flowing between the inputs and outputs. The own consumption of only 0.8 Watt or 0.5W active power per path is not measured and not displayed. 1, 2 or 3 external conductors with currents up to 80A can be connected. The starting current is 4OmA. Connections L1 and N must be present. Connection via a FBA14 to the Eltako RS485 bus with a 2-wire shielded bus cable (e.g. telephone line). The counter reading and the instantaneous power are transferred to the bus - e.g. for transmission to an external computer or the GFVS 3.0 software - and also via the FAM14 to the radio network. For this, it is necessary that a device address is assigned by the FAM14 radio antenna module as described in the operating instructions. Display also with FEA65D. The 7-segment LC-display can be read twice within two weeks even without power supply. The power consumption is indicated by a 1000 times per kWh flashing LED next to the display. Can also be used as a 2-tariff counter as standard: When 230V is connected to terminals E1/E2, the system switches to a second tariff. To the right of the display are the MODE and SELECT buttons, which are used to scroll through the menu according to the operating instructions. First, the backlight turns on. Then the total active energy per tariff, the active energy of the resettable memory RS1 or RS2 as well as the instantaneous values power, voltage and current per phase conductor can be displayed. Error message (false): If the external conductor is missing or the current direction is incorrect, false and the corresponding external conductor is shown on the display.This text is machine translated.
