5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 15151515 Time of use Rate Switching and Power Band Tariffs Time of use kWh rate recording operates according to a time switching matrix. The energy recorded at a particular rate may be charged at a fixed price throughout the effective time of the tariff or at a variable price according to the amount of power consumed. TIME SWITCHING The meter is capable of holding a total of 15 time switches. Each time switch consists of: 1. Switch start time in hours and minutes 2. Rate number the meter is to switch to (1 to 4) 3. Day of the week in which the switch should operate (Mon - Sun) Enabled switching days Time Switch Start Time Rate Mon Tue Wed Thru Fri Sat Sun 1 HH:MM 2 : 3 : 4 : 5 : 6 : 7 : 8 : 9 : 10 : 11 : 12 : 13 : 14 : 15 : The meter uses the RTC time (with any DST alterations) to switch between the configured TOU rates. A configured time switch will only operate on the configured days of the week. On reaching the start time of the a time switch the meter will show the defined rate as the active rate and record and consumed energy into the appropriate rate register The meter will hold a second set of future time switches as described as above. The second set of switches will be assigned a future activation date, upon reaching this date the meter will overwrite the active switches with the second set. This will allow seasonal rate switching in the meter. Example: If a three rate tariff was required with rate 1 active 00:00 to 07:00 and rate2 active for the rest of the day on weekdays with rate 3 active on weekend, as shown below: Rate 1Rate 2Rate 3 Mon Tue Wed Thur Fri Sat Sun
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 16161616 To operate this tariff the following time switches would be required in the rate-switching plan: Enabled switching days Time Switch Start Time Rate Mon Tue Wed Thru Fri Sat Sun 1 00:00 1      2 07:00 2      3 00:00 3   Tariff Rate Plan/ Demand Response Indication Assignment Billing Period The meter can calculate several features over a configurable billing period. The billing period consists of a configured start date and duration specified as either a number of days or calendar months. The Billing Period duration is defined in the range of: 1 to 115 days; or 1-12 calendar months. The Billing Period has a start date defined as DDMM. The day range is between 1st and 28th day. The month range is 1-12, January to December. No year is applied. The Billing Period end date is calculated as the start date plus the number of days or calendar months of the Billing Period. Where a monthly period is applied the meter will use the day specified in the start date as the start day of the next period following the specified number of month’s duration. The Billing Period ends at 24:00 on the Billing Period end date. At the end of a Billing Period the next Billing Period shall start automatically. Features using the Billing Period for calculation and logging of data include:  Block Tariff (start day)  Data logging  Monthly reads
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 17171717 Example 1 If a billing period were specified as 1 calendar month in duration starting on the 5th June the billing period would operate as follows: June July Aug5th 5th5thBilling Period ( 1 month) Billing Period (1 month)Block TariffkWh usage value resetNext B.P. automatically starts On the 5th of each month the Block tariff’s billing period usage value is reset. As a result the block tariff resets and uses block 1 price until the first power switch threshold is reached. Example 2 If a billing period is specified as 28-day duration starting on the 5th June the billing period would operate as follows: June July Aug5th 31st(calculated)3rd (calculated)Billing Period ( 28 days) Billing Period (28 days)Block TariffkWh usage value resetNext B.P. automatically starts The billing period is calculated 28 days form the start date. After each 28-day period the Block tariff’s billing period usage value is reset. As a result the block tariff resets and uses block 1 price until the first power switch threshold is reached.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 18181818 Block Tariff Power Switch Threshold Values The meter is capable of operating a Block tariff where the price of electricity is changed according to the usage from the start of the Billing Period. Price/kWhBlock 1Block 2Block 3Block4Monthly ConsumptionkWhPower Switch Threshold Values The meter has the ability to hold three Power switch threshold values; these values represent the value in kWh between blocks. The block tariff begins at the start of a billing period. The meter stores $/kWh tariff values for each block shown above (see tariff matrix). From the start of a billing period the total number of kWh’s or kWh’s consumed at current TOU rate, are recorded. When the recorded value reaches a threshold value, the $/KWH tariff will be changed according to the price defined for the next block. Block four has no limit. When reaching block four the meter will continue to charge at the block four rate until a new billing period is reached. If a threshold value is not entered then the previous block will remain operative.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 19191919 Tariff Plan The rate at which the meter will charge can be automatically changed according to the amount of power consumed over a fixed period. When using the power step tariff a set of $ per kWh prices are entered against consumption bands, the price altering once the power consumed reached that kWh threshold value. The tariff prices applied by the meter can be complied from: TOU tariff, Block tariff or a combination of both The tariff will consist of a matrix of up to 16 prices as shown diagrammatically: Step Tariff Power Bands Time Of Use Rates Block 1 Block 2 Block3 Block4 Rate 1 1 2 3 4 Rate 2 5 6 7 8 Rate 3 9 10 11 12 Rate 4 13 14 15 16 Meter selects $ per kWh value according the time of use rate and kWh consumed = Table of $/kWh charges The $/kWh price has the range of 0-9999.99999 Block Tariff - Example If a block tariff is configured, the meter will charge according to the usage during the month. Initially the meter will charge the Block 1 $/kWh rate until the threshold x kWh’s is reached. Upon reaching this threshold, the Block 2 $/kWh rate is applied and so on. A block tariff will use prices 1, 2, 3 and 4 only. Example - TOU Tariff When operating a TOU tariff, the meter will adjust pricing according to the Time Switching scheme set into the meter. If the meter is configured to switch to Rate 1 the meter will charge for energy at price set against Rate1 in the matrix. A TOU only tariff will use prices 1, 5, 9 and 13 only Combination tariff - Example A Block and TOU tariff may be combined. As the meter switches rates according to the Time switching plan the $/kWh charge dynamically changes according the Block tariff the meter has switched to. A combination tariff can use any of the 16 pricing slots. 0 kWh y kWh z kWh PS Threshold values x kWh
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 20202020 Demand Response tariffs will operate as TOU only. A Demand Response command will dynamically change the rate switching with energy recording and pricing switched to a particular rate. A combination tariff could not be reconciled. Demand Response Indication Assignment In order to operate the DR indicators on the CIU a particular rate will be assigned a DR indicator type in the Tariff Plan. Enable DR Indicator Step Tariff Power Bands Green Amber Red Time Of Use Rates Block 1 Block 2 Block3 Block4 Rate 1 1 2 3 4  Rate 2 5 6 7 8  Rate 3 9 10 11 12  Rate 4 13 14 15 16 When the meter is switched to a particular rate the Enabled Demand Response indicator will be lit on the CIU. This will operate whether the meter is in a normal Time switching plan or whether the rate has dynamically changed according to a Demand Response command. Example Rate 1 is not configured, Rate 2 is assigned Green, Rate 3 Amber, and Rate 4 is assigned Red.

5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 22222222 Real Time Clock The meter is fitted with a real time clock. The clock remains accurate by receiving time and date updates by the Central System. During periods of power failure an internal battery maintains the time and date. In battery backed mode the accuracy is maintained to within ± {tba} minutes per year (at nominal temperature) The time display is shown in 24-hour mode. In standard operation the date is shown as MMDDYY. Optionally the date may be displayed in an ISO standard format YYYY-MM-DD (Canada) The calendar used in the meter operates a standard Gregorian calendar and automatically corrects for leap years. The clock is configurable to operate all year without DST alteration or to switch automatically for DST during the summer months. Daylight Saving Daylight saving is a programmable option. If enabled, the start and end values are programmed: Month, Week (1, 2, 3, 4 or last), day, activation time (hours/minutes). The time adjustment can be configured e.g. +/- 1hour. When day light saving is activated the current maximum demand will be reset. The profile log will indicate daylight saving by an indicator placed against the data. Examples of setting day light saving Month = 4: Week = 1: Day = Thursday activates on the 1st Thursday in April Month = 4: Week = 2: Day = Friday activates on the 2nd Friday in April Prepayment operation general General prepayment operation is the same as the present 5211-meter with exception that credit is transferred from the Central System rather than from the present smart card. When credit is transferred to the meter which takes it out of debt and into credit, the contactor will not close until the meter receives a wake up message from the CIU. For safety, this assumes the customer is home. A $/kWh charge will be deducted each time a kWh is recorded in the active rate register. Holidays The meter can be programmed with up to 15 configurable Holiday Dates for the purpose of ‘friendly no disconnect periods’ and for the support of holiday kWh charges. The tariff that the Holiday Dates will operate in can be defined from the available rate tariffs 1 -4 if configured. If only one tariff exists then the Holiday Dates are set to operate using the default tariff. As the holiday dates may vary from year to year, the utility will have to update the dates via the AMS / smart card.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 23232323 Seasonal Non Disconnect Seasonal Non Disconnect will operate between a configurable start and end date/time. The period of time between the dates means the meter will not disconnect even if credit has expired. The time configuration ensures the meter connects/disconnects at a friendly time. If the meter was disconnected before the start date the meter will remain disconnected. If prepaid energy reaches zero during the no-disconnect period the credit register will continue to record energy usage as a debt. If the meter’s credit balance is negative at the end date/time the meter will automatically disconnect. Friendly Non-disconnect The meter offers a facility to prevent disconnection of the contactor when prepaid credit falls below zero. Each day type (Mon to Sun) will be programmed with a start and end time for the friendly zone. Friendly zones may differ on each day. If prepaid credit reaches zero during a friendly period the contactor will open when the end time of the zone is reached The ‘friendly’ periods can be set either by the factory or configured by the Field Unit Software or via the AMPY Management System /Central System Possible configuration options for Friendly Non-Disconnect Settings Weekday Start Time End Time Friendly All Day Not Configured Monday HH:MM HH:MM Tuesday HH:MM HH:MM Wednesday HH:MM HH:MM Thursday HH:MM HH:MM Friday HH:MM HH:MM Saturday HH:MM HH:MM Sunday HH:MM HH:MM Tariff Storage The meter stores two sets of tariff data active and future. The future tariff (if available) will come into force on its activation date (see data logging). Fixed Charges The meter can store two sets of fixed charges data for active and future. The future charge will come into force on its activation date. Future dates may be used to implement summer and winter seasons. Fixed Charges are collected every 1/100th of a week. This ensures the maximum amount the credit register decrements in reasonably sized amounts. The meter has 2 registers that can be set independently to recovery fixed charges.

Configuration example: Field Name Type Active Date SC1 Fixed Fee Total Active None SC1 Fixed Fee Total Future June 30 2002 SC2 Budget Billing Active None SC2 Budget Billing Future June 15 2002 The Fixed Charges registers have a range 0000.00 – $9999.999 Accountancy Configuration The maximum credit value will be $9999.99 and minimum $0.01 The maximum kWh rate will be $9999.99999 and minimum $0.00000 Credit Transactions The meter will hold the last 100 credit transaction ID’s in a rolling buffer, the last 5 credit transaction ID’s are always returned on the smart card. The Management System knows the credit transaction IDs assigned to each card. Credit Information Log The meter will hold a rolling record of last 16 transactions that been seen in the meter, and will store information for the credit value, credit Id, Status and time stamp for each record. An entry pointer flag denotes the last recorded transaction. Demand Response The meter is able to offer variable pricing to the customer using the TOU rates, which can be switched outside of the preset rate plan by a command from the Central System. The meter will respond by overriding the normal rate-switching plan and switching to a defined rate between a start and end time and date. The Demand Response command is defined as: Date Time Start MM.DD.YY HH:MM End MM.DD.YY HH:MM Switch to Rate 1 to 4 The meter has the ability to store 2 demand response commands as described above. Upon reaching the start time of the command the meter will switch to the defined rate and record any energy consumed after the start date into the defined rate register.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 25252525 Upon reaching the end time of the command the meter will revert back to the normal rate-switching plan While the meter is in a Demand Response period, prepay customers will be charged at the defined $/kWh rate. The CIU will reflect the change in rate and tariff by updating ‘Rate x charge is $x.xx’ display to the defined $/kWh rate. Example: The following scenario shows the rate switching of the meter when a Demand Response command is received. The example shows the start of the January 2006 for 4 days. The meter is configured to run a TOU Rate switching plan as follows: Enabled switching days Time Switch Start Time Rate Mon Tue Wed Thru Fri Sat Sun 1 00:00 1        2 07:00 2        A Demand Response command is sent to the meter with the following parameters – Date Time Start 01.02.06 12:00 End 01.02.06 18:00 Switch to Rate 4 The Demand Response command would have the rate switching effect on the meter: R4 R3 R2 R1MON 1st TUES 2nd WED 3rd THURS 4thDR Command ExecutedParameters:Start 2.1.06 12:00End 2.1.06 18:00Switch to Rate 4 On Tuesday 2nd the normal rate switching plan would be suspended. The Demand Response command would override the normal TOU plan. Any energy consumed between 12:00 and 18:00 would be recorded in the R4 register. Prepay customers will be charged at the appropriate $/kWh rate with the CIU showing the $/kWh rate. The CIU will indicate Demand Response LED’s according to TOU rate applied.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 26262626 Remote Disconnect/Reconnect When operating in credit mode the meter may be issued a command via the Central System to open the meters contactor. Upon receipt of such command the contactor will open and remain open, the metrology indicator on the display will not be shown. The command may be accompanied by an ad-hoc read request in the case of changes in tenancy. Reconnection of supply will be made following a command from the Central System. A ‘System Initiated Closure’ command will close the contactor upon receipt of the request without any further customer action. This assumes the utility knows the customer is present at the installation or that the installation is safe for reconnection. In some cases reconnection of supply will be offered to the customer following a command from the Central System. A ‘Customer Initiated Closure’ command will offer the customer the ability to close the contactor using the CIU unit. In this case, when a wake up message is sent from the CIU the meter will use this as a signal to restore supply. This mode will allow the utility to send a reconnect command without knowing whether the customer is present; the customer effectively reconnects his own supply. Following a ‘Customer Initiated Closure’ command the CIU will be instructed to display a supply-reconnected message Safety Reconnection The meter will ensure that the customer does not have a secondary supply connected (own generator etc.) when reconnecting supply. The meter is fitted with a detection circuit connected across the customer load side of the contactor to check for voltage present at the time of switch closure. If the meter receives either a ‘system’ or ‘customer initiated’ closure the meter will check the voltage on the customer supply side of the open contactor, prior to closure. If voltage is not considered present the meter will close the contactor (provided customer has chosen to close contactor in case of customer initiated closure). If the detection circuit detects the presence of external supply voltage the contactor will not close and the closure command will be returned with an error. Meter Test Mode (Metrology Testing) The meter can be programmed into a test mode to allow accuracy tests to be performed. All accountancy will be frozen and a separate test mode register used to accumulate power throughout the test. The test mode register will always be zero when switched into test mode. When the meter is disconnected and re-powered or reprogrammed out of test mode the accountancy will restart. Field Test Mode This operation can also be used in the field using an option called Field Test Mode. This allows a field operative to remove a customer meter from the wall, perform a metrology test, and then replace it back on the wall. The Meter will revert to normal operation after two Power-ups or after a 60 minutes safety period (the contactor will revert back to its original state prior to the operation).
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 27272727 Profiling The meter will record a profile of 15-minute interval kWh readings. Hourly or half hourly profiles are obtained by summation of profiles in the Central System. Up to 50 days of the most recent profiles will be stored within the meter, if the profiles are not down loaded within 50 days the oldest reading will be over written with the most recent. Each profile consists of the advance Wh’s since the previous 15 minutes profile. During power fail the missing kWh readings will be padded to maintain a sequential log. If the meter is disconnected for more than three days, the whole log will be cleared. When day light saving is activated the profile log will indicate daylight saving by an indicator placed against the data. Maximum Demand Active power is integrated over a configurable period of 1,2,3,4,5,6,10,12,15,20,30 or 60 minutes. The maximum demand value is calculated at the end of each period, the highest demand value is stored complete with time stamp information. Demand periods will be synchronized to the hour. For example, if the interval is 15 minutes, the starting times are 10:00, 10:15, 10:30 etc. The meter will record maximum demand values into one of 4 MD registers (MD1 to 4). Each MD register will be active according to the configured TOU rates i.e. if TOU rate 2 is active MD 2 register will be active. At the end of each day (00:00) the meter will record the four MD registers into a rolling log. The rolling log will contain the last 3 days of MD recordings. On storage of a new set of recordings the earliest set will be pushed out. At the same time the meter will reset the running MD registers 1-4. Energy Registration An infrared LED is mounted on the front of the meter, pulsing at a rate proportional to the measured load. The pulse value is identified on the meters fascia. The pulse can be used for checking the meter calibration and will illuminate continually to indicate no load (Anti Creep), with further information presented on the cycling display. Tamper Detection The meter is fitted with a tilt detection switch to detect removal of the meter from its base. Any triggering of the tamper switch is reported via status collection from the meter. Visually the tamper flag will be shown on the display. Optionally the meter may be configured to open the main contactor. Resetting of the tamper flag/supply reconnection can be achieved by system command or using the meter optical port. Optionally the tamper detection feature can be disabled
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 28282828 Power Outage Reporting The meter holds a rolling log containing the last 5 reported outages. Each log entry will consist of a time and date stamp of the outage plus the reconnection time and date stamp. The log will be held as follows: Occurrence Supply ON Date /Time Supply OFF Date/Time 1 2 3 4 5 Special Contactor Operation A mode is available to test the meter in environments where there is insufficient supply to fire the contactor. This mode can be used to test meters using RFL5800 and UTEC 620 test machines. The meter can be configured not to reaffirm the contactor position during testing by special command. The meter will revert back to its previous state after two power ups or after one hour has elapsed. A pre-condition with this operation is that the contactor is already closed.  Note: Once the contactor has been changed the meter will not attempt to operate the contactor for 60 seconds following the power-up. Whilst in this mode the contactor will not be periodically reinforced. Data Logging At the end of each month and on the tariff activation date the meter will store the 4 kWh rate registers, tariff identifier and date. The meter will store a rolling 6 months of kWh usage data for the 4 kWh rates in a rolling buffer. The oldest month’s data will be overwritten with the most recent month’s data. The tariff update registers will be overwritten on the next tariff update.  NOTE: The average daily kWh for any month can be calculated by dividing the monthly consumption by the number of days in the month (performed by the AMPY Management System). Each credit transaction is logged for accounting purposes.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 29292929 Emergency Time Log The meter will hold the last five values for when an emergency code has been received by the meter. The meter will store whether the emergency code entered was either a 24 hour E-Code or a 7 day E-code. An entry pointer flag denotes the last recorded emergency time. To calculate the number of days recorded in the log number of minutes should be divided by the number of minutes in a day (1440) and roundup the value to the nearest day. NOTE: This will allow the FUS to enter an e-code other that 1 and 7 days The log will record the following details depending on the minutes entered: Emergency Minutes Record In Log (days) 1440 1 4320 3 10080 7 Self Disconnects Logging The meter will hold the last five disconnect and reconnection date pairs. The disconnect time and date will be recorded when the contactors opens. The reconnection time and date will be recorded when the contactor closes. Example Log Entry Disconnect Date Reconnect Date Description 1 1-1-2006 10:34:34 20-1-2006 09:00:02 Complete entry 2 28-2-2006 03:23:23 1-1-1970 00:00:00 Part entry: No reconnect date ….. 1-1-1970 00:00:00 1-1-1970 00:00:00 No date logged 5 1-1-1970 00:00:00 1-1-1970 00:00:00 No date logged Decommission / Re-commission Data The meter is able to cope with changes in tenancy to the installed property by a Decommission Command. A decommission command can be configured in advance; the Central System will accompany a decommission command with an activation date and time for when the process should occur. The meter will only perform the operation at the configured date and time. A decommission command will have the following configurable parameters, including:  Reset or overwrite Credit register, configurable from 0 to maximum top-up value (if in prepay mode)  Clear credit transaction log  Option to open meters contactor
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 30303030 The decommission command will trigger a Snapshot of readings. Registers to be read and sent to the CS will include:  All kWh registers  Maximum Demand registers  Value of Credit register prior to Decommission (if in prepay mode)  Snapshot will be time and date stamped Re-commissioning will follow a Decommission. The Central System will send any new tariff settings including new tariff plans, TOU switch settings and a Contactor closure command (If required). At Re-commission the meter will also be sent a new Credit Register value (if not set by the decommission command). All re-commission commands will have an activation date.

Active Rate This register indicates the current active chargeable rate for kWh units. kWh Registers The Total kWh register and kWh registers for time of use rates 1 to 4 can be read. Each register has a field size of 00000.01 to 9999999.99 kWh. The four kWh rate registers and total kWh register can be reset to zero using the AMPY Field Unit software. $ Per Unit for Rates 1 TO 4 The rate per kWh unit for each of the four TOU rates, are settable in the range of $0.00000 to $9999.99999. Usage Yesterday The usage yesterday stores the previous days consumption in $ values. This is calculated on all charges normally applied within a 24 hour period and is settable in the range $0.01 to$9999.99.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 33333333 $ Usage per Hour The usage register stores information, in real time, on consumption in $ values. This is calculated on all charges normally applied within the last hour and is displayed from $0.01 to $9999.99. The register is calculated on a three second average. KW Usage per Hour The kW usage per hour register stores information, in real time, on the consumption in kW per hour. The register is calculated on a three second average. $ Usage Today This register stores the actual $ cost for the current day and includes all normal charges. The register is updated whenever the main credit register is adjusted and is displayed from $0.01 to $9999.99 $ Usage This Month This register stores the actual $ cost for the current month and includes all normal charges. The register is updated whenever the main credit register is adjusted and is displayed from $0.01 to $9999.99. $ Usage Last Month This register stores the actual $ cost for the previous month and is displayed from $0.01 to $9999.99. Active Fixed Charge 1 and 2 The two registers store the active values for the charge 1 and 2. Charges are collected every 1/100th of a week. The registers have a range 0000.00 – $9999.999. Future Fixed Charge 1 and 2 The two registers store the future values for the charge 1 and 2. The registers have a range 0000.00 – $9999.999. Future Fixed Charge 1 and 2 Activation Dates The two registers store the dates in seconds from 1/1/1970 that the future fixed charges will be applied to active fixed charges registers. Seasonal Non Disconnect Start and End Date/Time The two registers stores the date and time the meter will not disconnect/disconnect. Operation Mode The operation mode stores the meter configuration. The meter has two operation modes, pre-payment or credit.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 34343434 Power Fail Count This register stores the total number of power fails occurrences. The register has a range of 0 to 255. Wake Up Register This register stores the number of wake up messages sent to the meter, details are recorded in a rolling record for 10 entries and a counter will register up to ‘255 wake up’ attempts. This information can be retrieved using the AMPY Field Unit Software. Credit Transfer Register This register contains details for the last 10 transactions that have been seen by the meter, detailing time and date record, credit value /ID, and status. Credit History The meter holds the last 100 and the last 5 credit transactions in a rolling buffer. The log records the Credit ID information Credit Information (Transfer) Log The meter holds a rolling record of last 16 transactions that been seen in the meter, and logs the following information for the credit value: Date/Time, Credit ID, Value and Status An entry pointer flag denotes the last recorded transaction. Friendly Debt Register The friendly debt register ensures that wake up messages can not be used to invoke a configured friendly period when the accumulated debt in the meter is greater than the friendly debt level. This principle is also used when a credit amount is added which is not greater than the limit set in the friendly debt register, or if a wake up is invoked using both buttons of the Customer Information Unit. This information can be retrieved using the AMPY Field Unit Software.  NOTE: If the friendly debt register is greater than the accumulated debt in the meter, and an E-Code is successfully accepted by the meter, then the contactor will remain closed during the entered emergency period. Possible scenario explanations: Example 1 Friendly Debt Value is configured to $- 5.00 Customer balance (accumulated debt) $- 3.00 Customer presses both buttons on the CIU within 10 minutes of a friendly period start time, or during a friendly period. The meter will remain connected for the duration of the friendly period.
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 35353535 Example 2 Friendly Debt Value is configured to $- 5.00 Customer balance (accumulated debt) $- 6.00 Customer presses both buttons on the CIU within 10 minutes of a friendly period start time, or during a friendly period. The customer can have up to 5 wake up attempts per day, but after the 10 minute period the meter will disconnect. The meter will not connect for the duration of the friendly period. Energy Registration Modes The meter has the ability to register energy in one of three different modes, Cumulative, Detent or Net. In addition the meter will record all Received energy into a separate register. When configured to operate in one of the modes listed, the meter will accumulate energy into the Active Rate and Total Registers (Delivered energy registers) as follows: Cumulative (Sum) kWh When operating in Cumulative mode, any Received energy (Export/Reverse energy) recorded by the meter is added to the Active Rate register and ultimately to the Total Energy Register. In this mode, should the meter be removed and refitted upside down, the utility is protected against energy theft. Example If 5 kWh were recorded forward (Delivered) through the meter then 2 kWh reverse (Received) through the meter the energy registers would read: Active Rate Register 7 kWh Reverse (Received) register 2 kWh Detent (Delivered) kWh In Detent mode, Received energy recorded by the meter has no effect on the Active Rate register of the meter. The meter acts as if it is fitted with a reverse stop. Example If 5 kWh were recorded forward (Delivered) through the meter then 2 kWh reverse (Received) through the meter the energy registers would read: Active Rate Register 5 kWh Reverse (Received) register 2 kWh Net kWh With Net registration, Received energy recorded by the meter is subtracted from the active rate register and ultimately the Total Energy registers. Example If 5 kWh were recorded forward (Delivered) through the meter then 2 kWh reverse (Received) through the meter the energy registers would read: Active Rate Register 3 kWh
5 2 5 2 M E T E R F U N C T I O N A L I T Y U S E R M A N U A L 36363636 Reverse (Received) register 2 kWh Delivered (Export/Reverse) register Any received energy is separately recorded in the Received Energy register. This register will record the total received energy. The display layout is shown in the display section. It should be noted that the meter will not operate in Net mode when selected for prepay operation. Voltage Reporting The meter measures and records the voltage present at the meter for reporting purposes. The meter records the maximum and minimum voltage measured over a 1-day period. The meter holds a rolling log of the last 3 days max/min voltages. The instantaneous voltage present at the meter is also available by performing an ad hoc enquiry to the meter.
