Measurement

The Meter is a 220-240Vac, 50Hz, 5 - 100 Amp Single Phase Credit Meter. It contains an independent measuring element allowing consumed energy to be measured. The meter measures and registers kWh to class 1.0 and kVArh to class 2. There is a red LED mounted on the front panel of the meter, pulsing at a rate of 1,000 pulses per kWh or kVArh for energy registration and calibration checks. The meter’s internal measurement coefficient is 1 and therefore does not affect the supply’s phase angle.

Watchdog

All our products use a hardware watchdog that is built into the MCU. In the event of an illegal reset or software crash, the watchdog will automatically reset the processor ensuring meter functionality is un-effected.

Registers

Total kWh

Rate 1 – 4 kWh

Total kVArh

Rate 1 – 4 kVArh

The above registers are stored internally to 2 decimal places. They are displayed on the meter to 5 or 6 whole numbers and 2 decimal places. Therefore:

The registers range are 00000.00 – 99999.99 kWh or

The registers range are 000000.00 – 999999.99 kWh

Total Reverse/Export kWh Register

The meter can be configured to operate in one of the following modes:

Export Energy Registration

An export energy register stores the value of reverse energy measured by the meter. The register can be configured to be part of the display cycle or alternatively read from memory through the IEC1107 optical port.

Export energy will be recorded in the same way as forward (import) flowing energy using identical starting currents etc. The total export kWh’s measured are stored internally to 2 decimal places. The total export kWh’s are displayed on the meter to a maximum of 5 whole numbers or 6 whole numbers and 2 decimal places.


5

The Total Export kWh register range is 00000.00 – 99999.99 kWh or

The Total Export kWh register range is 000000.00 – 999999.99 kWh

Reverse Energy Detection

When reverse energy is detected, the meter can be configured to give a visual warning on the display. The display will alternate between its normal display and the warning message. The reverse energy-warning message is triggered when the reverse power exceeds the threshold level. This level is factory set and requires a reverse current of 5 amps or greater to flow for a period of 16 seconds. This equates to approximately 5 Wh. Once this level is reached the message will be displayed and can only be reset via the IEC1107 optical port using Ampy Software or HHU. The visual warning is:

Figure 1 Reverse Energy Detected

All energy consumed in this mode will be stored in the Export Energy Register as detailed above. In addition to detecting and giving a reverse energy warning, the meter also records the number of times reverse energy has been detected. This register can only be reset via the IEC1107 optical port using Ampy Software or HHU.

Unidirectional Register (Optional)

Both the import and export/reverse energy measured by the meter are accumulated in the Total kWh register.

Maximum Demand

Active (kWh) power is integrated over a configurable period of 1, 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30 minutes to give a kW demand for the period. The highest demand value will be stored in the Maximum Demand (MD) register with the time and date the MD occurred.

The MD register has a range 00.00 to 99.99 kW

The MD is configurable to be a rolling MD with each period starting every minute or slab MD with each period starting at the end of the previous period. i.e. 12:00 to 12:15, 12:15 to 12:30.


6

The MD reset is configurable to be the end of each calendar month, the end of a billing period, via the optical port using Ampy Software or HHU or through the sealable push-button.

Preset Demand Value

A preset Demand Value of kW can be set in the meter. Each time the MD exceeds this limit, the Demand Exceeded Register is incremented by 1. The Demand Exceeded Register is reset via the optical port using HHU. There will be 1 MD Exceeded Register for each Billing Period.

The Preset Demand Value has a range 00.00 to 99.99 kW

The Demand Exceeded register has a range 000 to 999

Quality of Supply

The meter measures and displays RMS voltage and current. The meter will also record separately, the instances the voltage goes above or below preset maximum and minimum voltage levels.

The Instantaneous Voltage Register has a range 000 to 999 Vac

The Instantaneous Current Register has a range 000 to 999 Amps

The Maximum Voltage Level Register has a range 000 to 999 Vac

The Minimum Voltage Level Register has a range 000 to 999 Vac

The Over Voltage register has a range 000 to 999 The Under Voltage register has a range 000 to 999

In addition to the above, the meter also records the number of power fails and the time and date of the most recent occurrence.

The Number of Power Failure register has a range 000 to 999

Factory / Meter Serial Number

The meter stores internally an 8 digit alphanumeric ASCII meter ID, an 8 digit manufacturing date, a 3 byte calibration date, a 16 digit Top Cover’s first removal date and an 16-digit serial number which is issued by the Manufacturer. These numbers are stored internally and can only be read, they cannot be changed once the meter has gone through the manufacturing process. The serial number is also printed and bar-coded (code 39 or 128) and placed in the serial number window.


7

Time Switching Functions

A time switching matrix held in FRAM allows various switching schemes to be programmed for use throughout the year. The matrix can be programmed with:

1, 2, 4 or 12 season’s (1 per month). Three day types per season. Weekday, Weekend 1 and Weekend 2.

50 Special Day types of which each can be programmed with a maximum of 5 dates.

For each day, a maximum of 8 time switches can be programmed.

Each time switch can be programmed to any valid rate and to turn the auxiliary relay on or off.

Calendar options

The calendar can be configured to be either Gregorian or Jalaali.

Daylight saving

Daylight saving is fully programmable for different zones throughout the world. The Start and the Stop fields can be set to any date, any month and either, First Week, Second Week, Third Week, Fourth Week or Last Week. Daylight saving Start and Stop dates can also be programmed for two years.

Date format

The displayed date format can be configured to be day/month/year, month/day/year or year/month/day.

Billing Periods

The billing period is set to 1 month, at the end of which the following data will be saved and then reset. Each set of data is stored against the billing period and the meter can store the previous 12 months worth of data at one time.

a) Rate1 kWh, Rate2 kWh, Rate3 kWh, Rate4 kWh, Total kWh, Total Reverse/Export Energy. .

b) Maximum Power Consumed (MD) data with related time and date of

occurrence.

c) The number of times the power consumed was over the Preset MD value.

d) Quality of Supply, maximum and minimum voltage levels, number of power outages and time and date of last power fail.


8

e) The last occurrence of the Terminal Cover and Top Cover removal,

with the time and date of last occurrence for each are stored.

Communication Log

For security reasons, each time the Meter communicates through the optical port, the Communication Log Register is incremented by 1. The time and date of the last communication is also stored.

Communication Log Register has a range of 000 to 999

Meter Memory

All the meter’s data is recorded in a Ferro-electric Random Access Memory (FRAM) under the control of the microprocessor. All the kWh registers are stored in the FRAM and are updated every 1/100th of a kWh. The FRAM is guaranteed for a minimum of 10,000,000,000 write cycles and does not require power to maintain the stored data.

Real Time Clock and Back-Up

The meter supports an internal Real Time Clock (RTC). In the event of a power failure this facility has a battery power back up. This battery has a total life certification of 20 years and a continuous operation life expectancy of at least 5 years. The supply from the battery is not used whilst the meter has an energy source feeding it. The RTC accuracy is typically ± 0.5 seconds per day at 23 degrees Celsius. In the case of an RTC fault, all consumption is recorded in Rate 1 kWh register. The meter displays RTC battery voltage level on the LCD. The meter stores the last time and date the meters clock and calendar was updated. The time and date of the new clock is used.

Anticreep

Below starting current, the meter enters into an anti-creep mode. In this state the meter registration LED is permanently lit and the registers do not increment. The Led remains lit until the meter current is increased in either the forward or reverse direction beyond the starting current. See Technical Summary for Starting Current values.

R or T for Rate or Tariff depending on options set.

The default display is always the Active Rate. When the meter is operating normally, pressing the push button allows various pre-configured parameters to be displayed. A pre-set option determines whether the display automatically cycles through all the parameters or waits for the display button to be pressed between each parameter. If during a manual advancing cycle the display button is not pressed within 30 seconds, the meter will revert to the default display.


12

Energy Registration

A red LED is mounted on the front of the meter, pulsing at a rate of 1000 pulses/kWh. The pulse value is identified on the meters facia. The pulse can be used for checking the meter calibration.

Push Button’s

Two front panel Push Buttons are provided. The first allows the user to view a pre-configured display cycle and the second is a sealable button that can be configured as an end of billing period reset/Max demand reset.

Auxiliary Relay

The meter has an auxiliary relay that can be programmed to open and close in conjunction with the Time Switch functions.

Optical Interface

The meter has a FLAG optical interface based upon the IEC 1107 protocol that supports all functions of Mode C including readout option. See Appendix B – Readout data with readout codes

In addition to the above, the meter is produced with separate versions of hardware/software that allows for the following communication options:

a) Modification of all the meters parameters with the exception of the calibration values can be made by authorized personnel through the optical port using level 2 FLAG password.

b) With the cal lock switch fitted and enabled. (Option) Modification of Rates and time switches, date and time data, daylight saving parameters and the cover removal data can only be made by authorized personnel through the optical port using level 2 FLAG password. All other data (calibration) can only be accessed and modified after the removal of both the Terminal Cover and Top Cover and setting the Cal lock switch.

RS232 (optional)

A 3-wire, true RS232 provides the same 2-way link to the meter as the optical port. Any RS232 compatible device such as a modem can be used for 2-way data transfer. The RS232 communicates at a fixed baud rate of 4800 bps.

Inductive Serial Data Port (optional)

The meter incorporates an Inductive Serial Data Port that transmits data through the top right hand corner of the case. See Appendix A – Inductive Loop


13

For Future Use This allows meter functionality to be extended by the addition of an easy to fit add-on module without restricting access to the optical port for the purpose of meter reading (there is no physical connection)

Fitting of modules is limited to removing existing terminal cover and replacing with a module.

Figure 3 Additional modules (future)

The data output provides all information available from within the meter and would support any module including:

Prepayment Power Line Remote Communication Radio and Telephone Communication.

Tamper Detection

No-Power Read

Manual Date/Time Programming


15

Tamper Detection (optional)

The meter incorporates 2 cover removal switches. The first detects Terminal Cover removal and the second detects Top Cover removal. Removal of either cover results in a Flashing Display, which gives a Visual Alarm that can only be reset by Authorized Personnel through the Optical Port using a HHU. Each switch has a separate 2-digit log of the number of removals and the time and date of the first removal.

Terminal Cover Removal register range is 00 – 99

Top Cover Removal register range is 00 – 99

No-Power Read (optional)

In the case of a power fail the meter can be configured to display either: Option 1: Total kWh, KVArh, Wh Max Demand and VArh Max Demand Or Option 2: Total kWh, Rate 1 kWh and Rate 2 kWh. The meter can also be configured in the number of attempts to read the meter in a twenty four hour period.(From 1 to 10.) To power the meter up, the meter reader simply holds a small magnet against the right hand side of the meter. A period of 45 minutes is then required for the timing circuit to fully recharge and allow for another meter read once the small magnet is held in place. Please note, if the magnet is removed from the side of the meter case during the no power read sequence, the display will fade away. A secondary back-up power source other than the RTC back-up battery is used for this purpose.


16

Manual Date/Time Programming (option)

The user has an option to be able to set the time of the meter. This option is at the expense of the reactive power measurement. When this option is enabled then this will also disable the normal operation of the (orange) MD push button. Pressing the MD push button will cycle through the following displays:

Date of Last Manual Setting (TP = Time Programmed)

Number of Manual Settings (RC = Reprogramming Count)

Date

Time If the date is displayed then pressing the MD push button and holding it for three seconds will cause the meter to enter date programming mode. The first digit will begin to flash. Pressing the (blue) display push button causes the flashing digit to increment. After 9 the digit will return to 0. Pressing the MD push button will select the next digit. Pressing the MD push button and holding it for three seconds will write the new date to the RTC and return the meter to normal operation. If the value is invalid it is not written to the RTC but instead the message ‘dt Error’ (Date/Time Error) is shown for 2 seconds and then the meter returns to normal operation If the time is displayed then pressing the MD push button and holding it for three seconds will cause the meter to enter time programming mode. The first digit will begin to flash and operation is the same as date programming mode. However, on successfully writing the time the seconds are reset to zero (Similar to the operation of most digital clocks). If at any point no button is pressed for ten seconds the meter returns to normal operation. When pushing and holding the MD push button the action to be performed when the button is pressed and held for three seconds will start after it has been held for three seconds and will not wait for the button to be released. It will not, however, act on the push button again until it has first been released. While the button is being held down the ten-second timeout timer is inactive.
