1 Single and three phase static Meters AM 160 AM 360 The AM X60 series electricity meters are modern, electronic devices, designed for application in AMM systems for monitoring, check and control of electricity consumption. The meter allows saving operating and servicing data and has communication module for two-way remote data transmission and control commands. Communication protocol is in accordance IEC and DLMS. The meter is possible to configurator in customer accordance. The meter is MID certified as well as WELMEC 7.2 compliant and has been designed to serve billing purposes. Measuring System The AM X60 series electricity meter: z Is a single or three phase static device; z Has one- to four-tariffs; z Measures active energy in class A or class B; z Measures reactive energy in class 2 or 3; z Complies with EN , and EN ; z Is designed for direct connection. z There is included real time clock with exchangeable battery At the heart of the measuring part is the microprocessor that executes all major calculations and operations. It converts analog signals from current and voltage sensors to digital, calculates needed measurands, control next processes and save data to internal memory. Calibration is made through software calibration constant and it means that the measuring system doesn t have adjustable mechanical parts. Next important functionality is testing and saving information for tampering or other illegal activities which can endanger metrology attributes. Microcontroller control display screen, disconnector, tariff switching, LED flashing etc. The buttons allows change displayed values and disconnector status. Meter can communicate via optical interface locally and internal communication module.

2 LCD display The meter display can show a wide array of measurand values in 3 modes. Each mode can display different measurands. The modes can be normal, service (with automatic screen rotation and manual rotation) and battery (with manual screen rotation). Manual control is possible to use via push buttons. The values are displayed with prefix OBIS code and unit. The display can show other icons which describe current status of meter. Push Buttons Push buttons are used for moving up and down through manual display mode. A long pressing of both push buttons at the same time reverses meter disconnector position, thereby connecting or disconnecting all circuits powered by the meter. Meter Communication interface There can be communicated with meter through optical or PLC PRIME interface. Optical interface PLC PRIME interface Switching Function (Scheduler) Scheduler manages tariff switching, activate event recorder and make other events for control next required functionalities. Registers Profile (Load Profile) Required values are saved to the registers automatically at regular intervals. If the capacity of memory is exceeded the meter start rewrite the oldest records. Registers History Based on the generated events of scheduler, limiter, buttons etc. there are saved preselected values (registers) with time stamp. For example, logged can be energy registers at the end of the billing period (e.g. last day of month at 23:59:59). If the capacity of memory is exceeded the meter start rewrite the oldest records. Events Recorder Each selected event is possible to save to the event recorder with time stamp. If the capacity of memory is exceeded the meter start rewrite the oldest records. There are saved next events usually: z Strong DC magnetic field occurrence when a strong permanent magnet is attached / removed; z Terminal Block Cover opening (tampering); z Meter / Communication Module Cover Opening (tampering); z Power Outages and Drops below / above a preset limit; z Current average value monitoring, within preset limits; z Tariff switching; z Disconnector tripping by customer, Limiter or push buttons; Limiter Based on current values of selected registers of voltage, current, power, energy etc. and defined limits are made events which can be used for control of meter activities (disconnector switch ON/OF, record to event recorder, tariff switching, etc.). Disconnector Based on settable requirements is possible to switch ON/OFF output current terminal with disconnector. Real Time Clock (RTC) The meter is equipped with RTC and date. The RTC can be adjusted via the optical interface locally or remotely via communication module. A battery with a long service life backs up the RTC during power outages. The battery is possible to change through open terminal cover (breaking sealing of terminal cover). Battery status is shown on the display. Tariff The AMX60 series electricity meters can manage up to 4 tariffs. Tariff currently active is indicated on the display by symbols T1-T4. Tariff switching is done either according to plan (switching table or scheduler) or directly (master system via PLC module). Switching priority is set in the meter configuration. Meter Registers There are available registers of active and reactive energy in the meter. The registers are divided by energy flow, phases, and tariffs. Other auxiliary registers show instantaneous effective values of voltage, current, active power and power factor. Tampering protection Meter is equipped sensors removal of terminal cover and meter cover and magnetic field sensor. The sensors detect illegal activities (tampering). Meter Design The AM x60 electricity meter, stemming from a design traditionally proven, is designed so as to withstand demanding operation conditions, enable simple handling and deliver increased protection from unauthorized consumptions. The set of sealing positions safeguards various concealed parts of the meter from unauthorized entry. The design solution offers a simple installation. The meter case and terminal block dimensions comply with DIN The meter cover enables stacking of the meters during storage.

The manufacturer discourages from using organic solvents, aggressive chemicals and abrasive cleaning preparations for optional cleaning of external surfaces from dust and other impurities. Prescribed storage temperatures are to be observed; failure to comply with these can shorten electronic parts service life. The meter is to be protected from humidity and moisture. Precipitations, humidity and liquids contain minerals, which cause corrosion of electrical circuits. If the meter becomes wet, it should neither be placed on nor dried by placing on or in a heat source (e.g. microwave, stove or heating bodies). The meter can overheat and some of its parts explode. The meter is not to be exposed to excessive heat; this can lead to covers deformation. The meter is not to be stored in cold premises. Humidity could condensate in the meter, (especially if warming up to nominal operation temperature follows), and damage meter electronic parts or have adverse effect on the meter insulation properties. Meter Transport The meter shall be packed for transport either in the original package, in which it was delivered by the manufacturer, or in such a package that can cause no damage resulting from handling or transport. Packaging Materials and Defunct Device Disposal: The devices at the end of their service life are to be handed over to specialized organizations, engaged in separation of used materials or their recycling. Unused devices are to be disposed of ecologically, in compliance with the Waste Act. Device. Contains no radioactive, carcinogenic or other material harming human health or environment. All plastic material used is recyclable. Packing Materials. Packing boxes are recyclable. Hand used boxes over to organizations as a source of secondary raw material or energy.
