M-bus converter current meter, MID

M-bus converter current meter with adjustable converter ratio and MID. Maximum flow 3x5A, stand-by loss only 0.5 Watt per path. Line installation device for assembly on DIN-EN 60715 TH35. 4 units = 70mm wide, 58mm deep. Accuracy class B (1%). With M-bus interface. This rotary current meter measures the energy from the flows flowing through the converters. The own consumption of only 0.5 Watt power per path is not measured and not shown. 1, 2 or 3 converters with secondary flows up to 5A can be connected. The starting current is 10mA. The N- connection must be available. The 7-segment LC display can be read twice within two weeks without power supply. The power reference is shown with a 10 times per kWh flashing LED. To the right of the display you will find the keys MODE and SELECT, which are used in the menu according to the instructions. First, the backlight turns on. After this, the total energy, the energy of the replaceable memory and the current, power, voltage and current, can be displayed per external conductor. The converter ratio can also be adjusted. It is set at 5: 5 and locked with a bridge over the connection terminals marked with JUMPER. The converter ratio is adjusted to the installed converter by removing the bridge and resetting it according to the instructions. After that, it is locked again with the bridge. The converter conditions are adjustable 5: 5, 50: 5, 100: 5, 150: 5, 200: 5, 250: 5, 300: 5, 400: 5, 500: 5, 600: 5, 750: 5, 1000: 5, 1250: 5 and 1500: 5. Error message (false): If the external conductor is missing or the power direction is wrong, the appropriate external conductor is displayed in the display. Data transfer M-Bus: When reading all values are transmitted in a telegram. The following telegrams are supported: - initialization: SND _ NKE, answer: ACK. - counter: REQ _ UD2, answer: RSP _ UD. - primary address: SND _ UD, answer: ACK. - Reset RS1: SND _ UD, answer: ACK. - slave selection for the secondary address, answer: ACK. - The device does not respond to unknown queries. - The transmission rate is automatically recognized. - The device has a voltage control. In the event of a loss of voltage, all registers are stored in the EEPROM. Change the M-Bus primary address: To change the M-Bus primary address, hold SELECT for 3 seconds. In the following menu MODE increases the address by 10, SELECT increases it by 1. If the desired primary address is set, wait for the main menu to appear again. Secondary address: - With the help of the secondary address it is possible to communicate with the energy meter in accordance with the standard EN13757. - The use of wild cards is possible.
