3 1.0 PRODUCT DESCRIPTION 1.1 General Information The i-meter EM and i-meter MF series meters are next generation metering products based on i-meter636 technology previously developed by Intellimeter Canada Inc. The i-meter EM and i-meter MF series meters represent a new level of functionality in revenue grade electricity meters - there can be up to 7 current inputs and 3 voltage inputs. The i-meter EM3 can be configured to one three-phase meter with or without neutral current and has a single line display. The i-meter MF can be configured for up to two three-phase meters with or without neutral current. The i-meter MF3 and i- meter MF6 are advanced revisions of the i-meter EM3 and both have a 3-line display (LCD). The i-meter EM/MF series has a wide range switching power supply. The meter is powered from phase-a voltage. The standard voltage range is 120V 347V (60/50Hz). Fig. 1-1 i-meter EM series meter 3

4 2.0 GETTING READY TO INSTALL YOUR METER 2.1 Configuration The i-meter EM and i-meter MF series of meters do not come with any configuration tool for configuration changes by customer. 2.2 Installation Check List Make sure you have received the right meter as per your order and packing list. 2.3 Electrical Code The installer is responsible for ensuring that all safety and local electrical codes are followed. 3.0 INSTALLATION Verify that the number of breakers is the same as the number of meters assigned for the panel board then follow the installation drawings. Mount the meter module. Install the voltage wiring to the meter module connectors and dress the wires so that they are protected from damage during feeder and branch circuit installation. Terminate the voltage reference chain to the designated 15Amp breaker and ensure the proper phasing is retained as per the installation drawings. Install the communication wiring (20AWG twisted pair) to the communication module terminals and dress the wires so that they are protected from damage during feeder and branch circuit installation. The communication cable is to be terminated to a junction box outside of the panel board by the electrical contractor. 3.1 i-meter EM/MF Series Meters Review the general information and wiring diagram. Carefully read all the WARNING signs and notes. Check the meter serial number and other information on the meter. A label on the top of each unit indicates meter assignment. Follow the installation drawings that are supplied with the units. Do not leave the secondary CT open when current is flowing through the primary circuit. Contact ICI if there has been a change made to the layout or if the assigned drawings do not match the actual layout. 4

5 4.0 OPERATION AND TROUBLE SHOOTING 4.1 i-meter EM and i-meter MF Series Meters Configuration The i-meter EM3 is configured for 1 point of metering. The i-meter MF3 is configured for 1 point of metering. The i-meter MF6 is configured for 2 point of metering Note: Any changes to the original configuration will need to be coordinated with Intellimeter Canada Inc. Project Management or Service. Please contact Intellimeter for inquiries and assistance at METERING RULES #1. Current Transformers (CTs) are directional. #2. Voltage references must be in phase with the load being metered and from the same source. Rule #1: If the CTs are mounted in the opposite direction, the polarity of the CT will be opposite. The arrow on the CT indicates the direction from LINE to LOAD. LINE HI LOAD Similarly, the H1 is on the LINE SIDE. All Intellimeter milli-amp current transformers 100:0.8A, 200:0.1A, 400:0.1A and 600:0.1A have self-shorting protection built into the device. They can safely be open circuited while under load. 5

6 External Current Transformers (CTs) #1 Intellimeter CTs 100A (ICI30CT108-B) #2 Intellimeter CTs 200A (ICI30CT21) #3 Intellimeter CTs 400A (ICI30CT41) #4 Intellimeter CTs 600A (ICI30CT61) #5 Instrument CTs X000:5A + 20 Turn CTs Twisted Pair #18-14 stranded colour code White (+) Black (-) White (+) Black (-) White (+) Black (-) White (+) Black (-) White (+) Black (-) The maximum length the CT leads can be extended is 30metres. 1 twisted pair wire only for each CT. Rule #2: Check to verify that the voltage potential used, as a reference voltage, is the same phasing as the loads being metered. ABC is ABC not CBA. The reference voltage must come from the same source. Voltage reference from another transformer is incorrect and causes inaccurate readings. Connect the voltage reference to the meters disconnect or terminals making sure it is the same phase sequence. Usually: Line 1 = Red or A phase Line 2 = Black or B phase Line 3 = Blue or C phase Neutral = White Note: Colour sequence may vary depending on the country and region. Rule #3: When the metering system is tested at Intellimeter s factory, the CT s are assigned to a meter and to a specific element of that meter. The CTs are recommended to be installed and used only with the meter and element that they have been tested with. Each CT has been identified so it can be easily installed by following the installation drawing that was designed for that particular distribution. Follow the Installation Drawing! If there is a discrepancy with the drawing in comparison to your distribution panel, call us for assistance. PLEASE CALL IF ANYTHING IS NOT CLEAR. IT IS DIFFICULT TO CORRECT ERRORS ONCE INSTALLATION HAS BEEN COMPLETED! Intellimeter Technical Assistance:

17 7.3 i-meter EM/MF series communication The i-meter EM/MF series ModBus module enables the meter to communicate on a ModBus system. It presents real time measurements, such as voltage, current, THD etc. The module supports ModBus RTU communication over an RS-485 network. By default, the module communicates at 9600 bps, 8 data bits, no parity and 1 stop bit (8N1). The communication parameters and ModBus ID may be changed through the ModBus registers ModBus Module Connection Fig. 2-5 Modbus Connection 7.4 i-meter EM/MF ModBus Register Mapping The ModBus module has many registers that present the metering data, both the historical data as well as diagnostic information for the module itself. The bulk of the registers are available using the Read Holding Register ModBus command, while the Read Input Registers provides direct read access to the non-volatile memory. 17

18 7.5 System Registers The system registers provide general information about the meter and the ModBus module. This information is the identification data and it generally remains constant with the exception of the up time. Address Name Type Access Description 1 Serial Number Uint32 R Serial number of the meter 3 Version Uint16 R Software version of the modbus device 4 OEM Id Uint16 R Manufacturer's id 5 Meter Model Uint16 R Manufacturer's model number 14 Number Of Uint16 R Number of phases, typically 3 or 6 Elements 15 Number Of Meters Uint16 R Number of meters, typically 1 or 2 17 Uptime Uint32 R The number of seconds since the last power cycle on the modbus module. 7.6 Real Time Clock (RTC) The ModBus module uses a real time clock to maintain the correct time for data storage. The RTC has a battery backup with a power off lifetime of 30,000 hours. When the module is powered there is no drain on the battery. The RTC is essential for correctly storing the consumption data, consequently the module will not store consumption data until the RTC is set. When the RTC is set for the first time, the NVM is erased and the module is considered to be initialized and will then store consumption data. The time may then be set to a future time or up to 15 minutes in the past. If time is set to more than 15 minutes in the past, then a special flag must be set in the Commit register to allow this. Setting the override flag will allow the time to be set into the past, however, storage will not continue until the time has caught up to its previous value. If a power cycle should occur before the time has caught up to the last storage reading then the NVM may adjust to store records as a new day. The previous data remains in NVM, however the day pointer is moved forward. Address Name Type Access Description 50 Seconds Uint16 R/W Set the time: Seconds 51 Minutes Uint16 R/W Set the time: Minutes 52 Hour Uint16 R/W Set the time: Hours 53 Day Uint16 R/W Set the time: Day 54 Month Uint16 R/W Set the time: Month 55 Year Uint16 R/W Set the time: Year 18

19 56 Commit Uint16 W Commit the YMD:HMS above by writing the bit mask 0x003f. Writing 0x00ff will override the back to the future protection. 58 UTC Uint32 R The current UTC time. This will be updated once the YMD:HMS has been committed. 7.7 NVM Access The data in the NVM may be read directly through the read input register command. The NVM is 512 kb or 256 kwords, which is broken down into 4 pages of 64 kwords. The NVM page is selected by writing to the corresponding NVM Page register, and data is then accessed by specifying an offset in the read input registers. The byte offset is calculated as follows:, where Address Name Type Access Description 70 NVM Page Uint16 R/W Sets the NVM Page for the ReadInputRegister NVM access 7.8 Daily Usage The entire NVM memory is available through read input registers however there is no file system to indicate the most recent entries. A second mechanism to access the current and previous day consumption values is available through the Read Holding Registers. Each day is broken into 5 minute intervals where each interval has 10 registers associated with it. The registers for the previous day start at address 10,000 and the current day starts at address 20,000. Each day has minute intervals, which equates to 2880 registers. The format for each record is as follows: Address Name Type Access Description X+0 UTC Uint32 R UTC of the record X+2 M1 kwh Uint32 R kwh for meter 1 X+4 M1 kvah Uint32 R kvah for meter 1 X+6 M2 kwh Uint32 R kwh for meter 2 X+8 M2 kvah Uint32 R kvah for meter 2 19

20 where, for the previous day and, for the current day. If data is not available for a particular interval, then the entry will be 0xffffffff. Data may not be available if the meter experienced a power interruption during that period. If the meter is reset or if the power outage lasted for more than 1 day, then it may take up to 2 days for the full data to be available using this method. Under these circumstances, the data may be read using the direct NVM Access method. 7.9 Meter Registers The instantaneous and cumulative energy data is available in float and 32 bit integer format. The latter is in a format similar to that of the i-meter636 and the i-metermf12 (other products from Intellimeter).
