Page 11: Technical Details
2.5.1 Overview Architectural overview Figure 2. Architectural overview Measurement technology The measurement technology used in the E220 meters is based on current shunts. Three measuring elements (one for each phase) measure the phase currents using shunts, and the phase voltages over resistor dividers. The analogue/digital converters transform both signals into digital voltage and current data. This data is then fed into the microprocessor, which produces the energy proportional values and adds the value to the corresponding values of the other phases. The sum is then transferred into the corresponding energy registers. Power supply The supply voltage for the meter electronics is taken from the three‐phase system. The meter will work correctly as soon as neutral and at least one phase are connected to mains voltage. In the event of mains failure, a voltage monitor ensures the safe storage of meter data and manages the restart when mains voltage is restored. Auxiliary power supply The auxiliary power terminal (L3) can be used supply external devices installed on or close to the meter. The auxiliary voltage output is tapped in the unfused and unmetered area.

Page 19: Before Installation
The installer is responsible for coordinating the rating and the characteristics of the supply side overcurrent protection devices with the maximum current rating and, in the case of direct connected meters, with the utilisation category rating of the metering equipment. Before installation Dangerous voltage on conductors The connecting wires at the place of installation must not be live when fitting the meter. Touching live parts is dangerous to life. The main fuse should be removed and kept in a safe place until work is completed, so that it cannot be replaced by anyone unnoticed. No overcurrent protection or automatic disconnection As the meter has no internal overcurrent protection and no method of disconnection from the mains, this must be provided by the end installation. Mounting Observe safety instructions Prior to starting the mounting of the meter, read and strictly observe the general safety instructions given in section 4.2 “Before installation”. Observe E VDE‐AR‐N 4101:2014‐03 Requirements for metering points in electrical installations in the low voltage network. The meter should be mounted as follows on the meter board or similar device provided for this purpose (see also section 3.4 “Dimensions”): Find the correct position for the meter. Make sure there are no wires underneath the holes to be drilled. Determine the desired type of mounting (open or covered mounting). For covered mounting, use the fixed bracket at the back of the meter. For open mounting, move the mounting bracket (provided with the unit) to the top of the meter. See the following figure.

The command can be only executed when the LMN module is plugged‐in to the RS‐485 interface. This reset causes the following actions to be performed in the E220 meter: The symmetrical key for the exchange of TLS certificates is set to the delivery state (the register “Operational key” is thereby set to “Initial key”).

Page 34: Firmware Update
All TLS certificates and temporary TLS properties including session keys are explicitly headed by ‘0x00…00’. The transmission counter (see FNN LMN requirements for symmetric encryption for the exchange of TLS certificates) will not be reset. The state “Operation in a secured SMGw environment” is disabled. The command “Reset cryptographic parameters” can only be executed, if certain conditions are fulfilled. The time “Tclosed” must be set to 30 seconds. 5.5.2 Firmware update Firmware updates are not possible. Optional modules 5.6.1 General The E220 meter has a module slot above the terminal block. In a standard delivery, the module slot is covered with a dummy cover. In this case, the meter operates as a standalone 1 rate meter. Change modules in power OFF mode only To install or replace a module, always disconnect the meter from power. 5.6.2 Dual rate module To plug in the dual rate module to the E220, the power must be switched off. After power‐up, the meter switches to the dual rate mode. As soon as the meter operates in dual rate mode, it writes to registers x.8.1 and x.8.2. The corresponding registers in the rolling list are displayed on the display with the appropriate OBIS code (see also 5.1.1 “Basic layout and symbols”). The OBIS code of the respective active register flashes (0.25 s off / 0.75 s on). In the background, register x.8.0 continues to grow as the sum of x.8.1 and x.8.2. There are four different types of dual rate modules for the control of tariffication. The meter automatically switches to the correct rating variant by means of a predefined PIN code in the module (factory setting). The basic variant of the meter (consumption, generation or bidirectional meter) defines the type of the total registers in the meter (+ A: 1.8.0; ‐A: 2.8.0). The dual rate module can only operate with an existing total register. © Landis+Gyr D000070822 en f – E220 Series 3 – E220‐AMxD – User manual ... - Page 35 Operation 35/42 There are four different variants of the Dual Rate Module: Module type Description Module B2T/L2T Import 2‐rate, export 2‐rate (B2T/L2T); 230 V (x.8.1) = 230 V for 1.8.1 and 2.8.1 = 0 V for 1.8.2 and 2.8.2 Module B2T/L2T Import 2‐rate, export 2‐rate (B2T/L2T); 230 V (x.8.2) = 230 V for 1.8.2 and 2.8.2 = 0 V for 1.8.1 and 2.8.1 Module B2T/L1T Import 2‐rate, export 1‐rate (B2T/L1T); 230 V (1.8.1) = 230 V for 1.8.1 and 2.8.0 = 0 V for 1.8.2 and 2.8.0 D000070822 en f – E220 Series 3 – E220‐AMxD – User manual © Landis+Gyr ...

Page 38: Maintenance
38/42 Maintenance Maintenance Service The E220 meter has no serviceable parts. Device service is available from the local Landis+Gyr representative. Troubleshooting If the meter is not operating correctly, check the error displays and LED (see section 5.1 “Display” for instructions on how to use the display). If there is a problem with meter operation, the following points should be checked first: Is the mains voltage present (check meter display)? Has the maximum operating temperature been exceeded? Is the meter visibly damaged? Is there any error code on the display (code F.F.)? The error codes are described in section 6.2.1 “Error codes”. 6.2.1 Error codes Critical Error A critical error means that a legally relevant function is no longer working properly. Values may not be used for billing without validation. Critical errors indicate severe problems, but the device can still operate. However, the data measured and stored in the meter may be corrupted and it is recommended that meters showing critical errors are returned to the designated Landis+Gyr service centre. If the device is displaying the F.F. register with an error code, there is a critical error. If the error register is not cleared, the failure code can be viewed in the installation/service menu or by reading the F.F. register through the communications interface. Critical errors can only be cleared via communication with a reset command. Due to the temporary nature of communication errors they do not cause the F.F. register to be displayed. However, communication errors get stored in the error register. They are cleared when communication is restored. Communication errors do not usually require meter replacement. These errors do not cause the F.F register to be automatically shown on the display, but are stored in the error register. The meter continues normal operation and does not usually have to be replaced. ... -
