Mx37y ─ Single- and three-phase electronic meters with built-in DLCmodem, GSM/GPRS modem or RS485 comm. interfaceRemote setting of an energy / powerconsumption thresholds of individual customers.Remote setting of an energy / powerconsumption threshold groups of customers (e.g.“Code Red”), by a broadcast with group identifier.Retrieving device status.Remote connecting and disconnecting the energysupply of individual customers.Fig. 34: Assembly of ZO3 plug-in switching device5.1. On request reading of E-meterThe “On request reading of E-meter” is a service formeter reading requested by a call centre agent duringa customer call. The meter reading represents thecurrent reading of the meter display.5.2. Billing registers reading of E-meterMeter read in order to prepare energy or other objectinstances measurement values. Values are the basisfor preparing an invoice paper. In this case the meterreading is stored at the end of a billing interval andcaptured at a specific defined moment. Meter readingis time stamped at the end of a billing interval. Abilling interval is configured in advance and can bechanged remotely.5.3. Scheduled reading of E-meterThe meter reading is scheduled later e.g. at themoment of a tariff changeover, or at an energysupplier switch.Fig. 35: MT372 meter with ZO3plug-in switching device5. Additional meter functionsCollection of energy consumption information insubsequent billing periods of individual customersand/or a (larger) number of customers.On request, reading of energy consumptioninformation.Collection of supply quality information (e.g. sags,voltage measurements) of individual customers.Collection of information saved in profiles ofindividual customers and/or a (larger) number ofcustomers.Collection of power failure duration information ofindividual customers and/or a (larger) number ofcustomers.Prepaid functionality.Setting and retrieving different tariff structures(i.e. different combinations of tiers and timeslots)including the consumption thresholds in the meterof individual customers and/or a (larger) numberof customers.5.4. Historic reading of E-meterMeter reading for analysis, for reference, for disputeson invoices and to enable recovery of lost data, bothbilling and scheduled readings.5.5. On request reading of G-meterThe “On request reading of G-meter” is a service ofelectricity meter. Read is invoked by a call centreagent during a customer call. The meter readrepresents the current reading of the meters. Externalmeters are connected to the E-meter with the M-Bus.5.6. Billing registers reading of G-meterThe ”Billing registers reading of G-meter“ is meterreading in order to prepare a monthly, quarterly oryearly invoice. In this case, the meter reading isstored at the end of a billing interval and captured ata specific defined moment. Gas meter reading is timestamped at the end of a billing interval. A billinginterval is configured in advance and can be changedremotely.5.7. Scheduled reading of G-meterThe gas meter reading is scheduled later e.g. at themoment of a tariff changeover, or at an energysupplier switch.26Mx37y_Technical_Description_ENG_v2.00.doc

Historic reading of G-meterMeter reading for analysis, for reference, for disputeson invoices and to enable recovery of lost data, bothbilling and scheduled readings.5.9. Device statusDuring its operation, the meter performs tests ofindividual functions, and in case of an error it createsthe “Self-Test Error” event.The detected errors are represented with FF flag onthe LCD display. A corresponding error bit in the FFregister is set and an error event is recorded in eventlog. The FF register is 32 bits long. It is organized in 4groups of errors:Time base errorsAccess data errorsChecksum errorsOther errorsLIST OF ERROR STATUSESTIME BATTERY DISCHARGEDTIME INVALID-TIMEACCESS RAMACCESS FRAMACCESS MEASURECHECKSUM ROMCHECKSUM BACK UP DATACHECKSUM PARAMETERSCHECKSUM RAMLIST OF EVENTS IN EVENT LOGFATAL ERRORBILLING RESETDEVICE CLOCK CHANGEDPOWER RETURNEDPOWER FAILUREEVENT LOG CLEAREDLOAD PROFILE CLEAREDL1 POWER FAILUREL2 POWER FAILUREL3 POWER FAILUREL1 POWER RETURNEDL2 POWER RETURNEDL3 POWER RETURNEDMETER COVER OPENEDTERMINAL COVER OPENEDNO CONNECTION TIMEOUT (onlyDLC meters)PREPAY TOKEN ENTER SUCCESSPREPAY TOKEN ENTER FAILEDPREPAY CREDIT EXPIREDPREPAY EM CREDIT EXPIREDPREPAY EM CREDIT ACTIVATEDhex0x010000000x020000000x000100000x000200000x000400000x000001000x000002000x000004000x00002000hex0x00010x00100x00200x00400x00800x20000x40000x80010x80020x80030x80040x80050x80060x80100x80110x80120x80130x80140x80150x80160x80175.10. Tariff structure configuration of E-meterSetting of tariff structures with different combinationsof tiers and timeslots including the consumptionthreshold in the meter (Activity calendar, special daystable, register activation).5.11. Remote customerconnection/disconnectionA plug-in switching device (ZO3…) is used for remotedisconnection and reconnection of electric network toindividual customers.The meter controls the switching device via controloutput or via M-Bus.Control can be performed locally (from the meter) orfrom a remote control centre using the meter AMRcommunication.5.12.
