1.8.- Verification impulses

The device features two verification LEDs: one for verifying the active energy, and another for the reactive energy.

The weight of the LEDs depends on the version of the meter, being 20,000 imp/kWh (kVArh) for the indirect and semi-indirect meter, and 4,000 imp/kWh (kVArh) for the direct connection meter. The LEDs remain lit when the current is below the meter's start-up current. Once the start-up current has been passed (because of the existence of either active or reactive power consumption), the LEDs turn off and emit pulses in proportion to the energy being measured, in accordance with the cadence indicated on the characteristics label.

Both LEDs have metal loops and a profile which allows them to be attached and to help position the verification port.

1.9.- Button

The device uses two buttons, employing a system of either short or long button presses. A short press is understood to be one that lasts less than 2 seconds, and a long press one that lasts more than 2 seconds. The effect of pressing each button depends on the version of the meter. One of the buttons is sealed in order to prevent the meter being tampered with by unauthorised personnel.

1.13.4.- Version with Optocoupler output

The meter could have a optocoupler output card to send pulses related with the energy read by the meter. The maximum voltage is to apply is 24 V d.c.

1.14.- Real-time clock

The meter features a real-time clock able to maintain the date and time with a loss of accuracy of less than 0.5 seconds/day, as specified by the UNE EN 61038 standard.

The clock maintains this precision both when powered using the electricity network and when using its own battery.

1.15.- Reserve power

The meter is equipped with a battery that allows the real-time clock to continue running. This battery is non-removable and is designed to provide energy for a period of 5 years whilst the meter is otherwise without power. When the meter is powered as normal, the battery consumption is practically zero. The use of laser-sealed batteries ensures minimum autodischarge, making it possible to guarantee the battery for the 20 years of service life of the meter.

1.16.- Optical communication port

The equipment, in all the different versions, features an optical serial communications port, in accordance with the UNE IEC 62056-21:2003 standard. The communications port is fully compatible with the optical ports approved by the major electricity companies.

The device can be reset to the initial factory settings using this local function.

1.21.- Contracts

In addition to the basic measurements, it is also necessary for the device to carry out a series of calculations that will allow for adequate billing, which leads us to the concept of contracts.

A contract is understood to be the set of parameters that structures the handling of the measurements, to be carried out by the analyser, in order to reflect the contracted billing agreements.

1.21.1.- Number and contracts assignment

The meter has three defined contracts.

1.21.2.- Contract parameters

A parameter is considered to be defined if it has a value assigned to it. It is considered undefined if it is blank.

A parameter that is not used will not be able to have any value assigned from previous parameterizations and, as such, will be left undefined.

Activation date

This is the date from which the meter must use the contract parameters to calculate the data necessary for billing.

A season is defined as a period of time into which a calendar year can be divided and during which time the billing conditions associated with it do not vary. The maximum number of seasons is 4.

Two types of season are considered:

Winter / Summer seasons. These split the year into two unique seasons and are

delimited by the dates of the official daylight saving clock changes, without the need for

any parameterization. It adjusts the data automatically every year.

Defined seasons. Each season begins on a determined date, with its end being marked

by the start date of the next chronological season, regardless of the year. Each one is

identified by a number, starting at 1 and incrementing by one unit up to the maximum of

Type of days

The days of the year are classified as either:

Working. Holiday.

Working days are considered to be Monday, Tuesday, Wednesday, Thursday and Friday. They all receive the same tariff treatment throughout an entire season.

Holidays are considered to be Saturday, Sunday and all other days considered as nonworking. They all receive the same tariff treatment throughout an entire season. Holidays other than Saturdays and Sundays will be identified by their dates, the format of which can contain wildcards.

Tariff periods. Type of day

A tariff period is each hourly block in which a determined tariff is applied. For the regulated market and ATR, the Public Administration defines them each year. In addition to these ones, there may exist other different periods agreed upon in contracts between the Client and the Supplier. There will exist a minimum of one hourly block and a maximum of six. Each period is identified using an incrementing number, starting at 1.

Type of day

The type of day is the total set of tariff period assignments made to each of the 24 hours in a day.Each type of day is identified by number, starting at 1 and incrementing by one unit for successive

types.

Working days and holidays have an associated type of day for each season. Each special day also has an associated type of day.

Power ratings

Each tariff period has an associated power rating, which corresponds to the value of the power contracted in each period. This is the base of the calculations for the billing of the excess power demanded from the network.

In the event that this parameter is not defined in any tariff period, it will be understood that there is no power contracted by period, for which reason the excesses are not calculated. If the power rating is defined in one or more tariff periods, the rest of the periods in which it is not defined will be considered to have a defined power rating of zero and the excesses will be calculated for all the periods.

1.22.- Billing closures

A billing closure is considered to mean the storage, in a memory register and at a determined moment, of the following values:

Values indicated by the energy totalizers at a given moment (absolute reading). Values of the energy measurements since the previous closure or since the start-up

of the meter, in this closure is the first (incremental reading).

The measurements and calculations that must be stored are:

Active energy, as both absolute and incremental values. Inductive and capacitive reactive energy, as both absolute and incremental values. Calculated average maximum active power in a quarter of an hour. Calculated power excesses.

The billing closures are over the total measurements and all the tariff periods of the active contracts.

Each closure includes the associated date and time when it took place. A minimum, configuration, time must elapse between two consecutive closures, expressed in minutes. By default, this time is 10 minutes.

The meter keeps a historic register of the 12 most recent closures for each of the contracts that it holds, arranged chronologically from the most recent to the oldest.

The types of closure are:

This closure can be made at any time by means of a manual order, by pressing a

button or sending a communications message. The power values are considered up until the end of the quarter-of-an-hour integration period immediately prior to the moment in which the order is given. The energy values will be those indicated by the totalizers in the moment the order is received. Ordering a closure manually using the button affects all of the active contracts. A closure via a communications message may affect one or more of the active contracts.

Automatic closure. Programmable parameters indicate the date on which each

contract is to be closed automatically. The date can contain wildcards in the month and year. This type of closure can affect one or more of the active contracts

An extraordinary immediate closure is automatically carried out in the following cases:

Change of transformer ratio. This affects all contracts. Change of contracted power per period. This affects the modified contract. Change of season or type of day. This affects the modified contract.

THREE PHASE STANDARD CIRWATT B METER

CIRWATT B THREE PHASE INSTRUCTION MANUAL

20 / 53

1.23.- Maximeter

The maximum is the highest active power value demanded within a period of 15 minutes, in the time between two consecutive billing closures.

The 15-minute periods will coincide with the quarter-of-an-hour integration period of the load curve. As such, for each hour they will begin on the minutes 0, 15, 30 and 45, ending with the start of the following period.

The maximums are associated with each of the defined tariff periods and to the entire set. Each one of these values is associated with the date, hour and minute in which it was produced. Those 15-minute periods in which a synchronism action, a power supply cut-off or reconnection, or a parameter change or intrusion occurred, or those which have an invalid bit, will not be taken into account when the maximum is calculated.

1.24.- Defined, active and latent contracts

A contract is considered to be defined when at least the seasons and types of day are defined. A defined contract is active when it is being used to do the calculations necessary for billing.

The TB three-phase meter also features latent contracts. The latent contracts function allows for the parameters of the active contract to be modified prior to the date on which it comes into effect. A contract changes from latent to active in the moment in which the activation date is reached, even if the device is without power or is starting up when power is recovered.

When the activation date of a latent contract is reached, the meter automatically carries out an extraordinary immediate billing closure of the affected contract. The parameters that the latent contract has defined are included in the active contract; the parameters of the latent contract become undefined, with the latent contract thereby being deleted at this point.

In the event that there exists an active contract and other, different ones are defined and activated, the registered information will not be altered in the moment of activation and all the data of all of the active contracts will be stored and will be available for viewing.

1.25.- Modifying contracts

Modifying a contract is understood to mean defining, changing or deleting any parameter of a previously defined contract.

Modification can affect an active or a latent contract (if there are any). Even though the parameters of a contract form a single set, modifications can be made

partially and independently by parameter group. These groups are determined by the coherence that exists between the parameters found in each of them.

In the event that a group of power ratings is modified, it may be necessary to previously modify the group of seasons and types of day in order to maintain coherence.

THREE PHASE STANDARD CIRWATT B METER

CIRWATT B THREE PHASE INSTRUCTION MANUAL

21 / 53

The groups are:

Holidays (up to 15). Power ratings. Date of automatic billing closure. Seasons (4) and types of day (6).

Modification is done by complete groups, deleting the existing parameters and replacing them with those defined in the modification.

The modification of the Powers (power ratings) and Seasons/Types of Day groups triggers an automatic billing closure, which will take place prior to the implementation of the modification. In the event that the two groups are modified in a single operation, only one billing closure will take place. The rest of the groups are modified immediately, without triggering any closure.

If the modification supposed a reduction in the number of billing periods, the meter/analyser at the moment in which the modification is made and a billing closure takes place - will do the following:

Store in memory and make available for viewing the registers of the closures made up

to that point. Keep the values of the global totalizer and of those whose period number remains.

From this moment on, the global totalizer and the totalizers of the periods that have kept

their number with the new definition will be viewable and will continue to increment, with

those that have been deleted no longer being viewable or registered.

In the case of modifications to contracts that suppose extensions to billing periods, a billing closure will be carried out when they are activated, with the information registered up to that point and the values of all of the totalizers being maintained. The totalizers of the new periods start with the initial value of zero, and the existing ones increment from the value they held previously.

1.25.1.- Modifying an active contract

The modification of an active contract can effect one or more groups of parameters, and their activation will be immediate. Depending on the parameters, and before they are changed, an automatic billing closure for the affected contract will be carried out.

1.25.2.- Modifying a latent contract

The modification of a latent contract can effect one or more groups of parameters, but does not trigger any automatic closure.

If the activation date is prior to the current date, the effect will be the same as with a modification of an active contract, and said activation date will be ignored.

THREE PHASE STANDARD CIRWATT B METER

CIRWATT B THREE PHASE INSTRUCTION MANUAL

22 / 53

If a modification takes place with an activation date which is different to the existing date and which is after the current one, the date from the latest modification is taken as the new activation date.

1.25.3.- Deleting contracts

Deleting a contract leaves all previously defined parameters undefined, and removes all data referring to it from the screen.

If more than one contract has been defined and is active and one of those belonging to the set is deleted, a billing close for the contract to be deleted is carried out in that moment and from then on the information referring to the deleted contract is removed, with no information about it being displayed other than that relating to any existing billing closures. The rest of the contracts and the corresponding totalizers are not modified.

1.26.- Load curve

The meter features two load curves, in accordance with the specifications included in Royal Decree 2018/1997 and its Complementary Technical Instructions. Both load curves store registers with the number of fields demanded by this standard. The depth of the register is in both cases 4,000, and the integration period is completely user-configurable. With a period recorder of 1 hour, the meter can save more than 5 months of load profile.

In the event of voltage drops or clock changes, any gaps produced in the load curve are filled in with zeros.

An incremental load curve value that does not correspond exactly to the time at which it is included is marked as invalid. For example, this would be the case for a value that corresponds to the consumption of several time different times.

If in the request for a load curve quantities that are not registered on the device are requested, those that are registered will be sent and zero and void will be sent for those that are not registered.

In both cases, the resolution is 6 digits for the energy values measured in kWh or kvarh (the same as that in the meter display).

The load profile is initialized if the period of register is modified.

1.27.- Power excesses

These are calculated according to the average power in the last quarter of an hour and the contracted power, in accordance with RD164/2001.

THREE PHASE STANDARD CIRWATT B METER

CIRWATT B THREE PHASE INSTRUCTION MANUAL

23 / 53

Where:

Pdj = power demanded in each quarter of an hour of the period i in which Pci has been exceeded. Pci = power contracted in the period i in the period in question

1.28.- Events

All of the dates of setup modifications, battery changes, clock changes, billing closures, etc. are registered.

The device has a storage capacity of 200 registers. Data within the file is organized in a round-robin structure. This means that once the memory is full, the new data will be saved over the top of the oldest data. This system ensures that the meter always has up-to-date information, and that this corresponds to the latest obtained data.

1.29.- Daylight saving time

The meter will automatically make the changes necessary for daylight saving time. In the event that the device is without power at that moment, the change will be made when power is restored and the device starts up.

The parameters that define this change have two different formats: one of them is generic, allowing for automatic annual updates, and the other incorporates the parameters included in the specific message from the communications protocol. The formats are:

Generic format, independent of year, with month, day, time, and pre-established move

forwards or backwards, in accordance with current regulations (last Sunday in March,

and last Sunday in October). Format specifying the year, with month, day, time, move forwards or backwards.

The daylight saving parameters, regardless of which format they are programmed in, are automatically updated at the beginning of the year, in accordance with the generic format. In the event that the message for the updating of daylight saving time is received within the communications protocol, the format will be modified according to what is established in last message.

1.31.- Safety

1.31.1.- Tampering detector

The equipment will generate an event and activate the alarm whenever its cover is lifted. The alarm can only be deactivated using communications protocols. The minimum time between two tampering events is 60 seconds.

During the initial startup, the meter will wait 72 hours before generating the first tampering event in order to avoid its activation whilst the authorized installer is fitting the equipment.

1.31.2.- Protection of the information stored in memory

All access to the meter memory via remote connections is protected by read and write keys. These keys have more than 4 billion different combinations, granting the meter very strong

protection against attempts to alter the registered information (energy curves, events, billing, setup).

1.32.- Measurement validation criteria

Energy, maximeter and excesses registers will be invalidated following the occurrence of a series of events that implies that their values are false. In the specific case of the load curve registers, there exists an invalid bit (IV) which indicates that that register is no longer valid. The events that lead to this invalidity of the measurements are described below.

1.32.1.- Time synchronization with drift > T1 = 30 seconds

The quarter-of-an-hour period in which the synchronization takes place will be ignored for the power calculation.

1.32.2.- Time synchronization with drift >10 minutes

The measurement is invalidated, i.e. flag IV = 1.

1.32.3.- Communication failure between meter and analyzer

If the communications failure coincides with the quarter-of-an-hour period change, and its duration is longer than 30 seconds, the affected periods will be ignored for the power calculation.

2.9.1.- Voltage out of limits

To calculate the variable when the voltage is out of limits, 5 variables must be programmed on the meter: Nominal voltage, Threshold separation, Higher voltage set point, Lower voltage set point, Minimum duration out-voltage.

The following information will be saved for each event: kind of event (Exceed voltage or faulty voltage), start date and hour, end date and hour, with a resolution of a second.

A) Nominal voltage

This is the nominal voltage value of the supply (phase-phase voltage). This value will be the one to take to consider is there is an event on the line: if the voltage is out of limit in the upper lever or in the lower level. For CT meters this voltage will be the primary voltage.

B) Threshold separation Is the limit value in % of the nominal voltage where all the values under this limit will be

considered as an interruption. If the value is below the limit, the data will treat as supply interruption (see point 2.9.2).

C) Higher voltage set point Is the limit value in % of the nominal voltage which is summed to the nominal voltage

where all the values above this limit are considered overvoltages. If this value is set to zero, the meter will not register this kind of event.

D) Lower voltage set point

Is the limit value in % of the nominal voltage which is rested to the nominal voltage where all the values below this limit are considered interruptions. If this value is set to zero, the meter will not register this kind of event.

3.- METER OPERATION

In this section we describe the behaviour of the equipment from a functional point of view. In other words, we will explain how to manage all of the information that it gives us, as well as how to configure the different functions of the system.

3.1.- Navigation and viewing modes

To navigate through the different information screens, the read button will be used. Movement within the same level will be done using short presses of the button. To access a higher level, a long press will be used. The device will return to stand-by mode 60 seconds after the last press of the button.

3.1.1.- Stand-by mode

The device is in this mode by default until one of the buttons is pressed. The stand-by screens are designed to present information cyclically, without the need to carry

out any action upon the meter. This kind of navigation is exclusive to the stand-by mode. The scrolling line will alternate the information once every 6 seconds. When the read button is

pressed once quickly (short press), the reading from the totalizer being displayed in that moment will be frozen on the screen.

Using short presses, the user can navigate manually through all of the defined totalizers. On devices configured for a simple active tariff, the stand-by screen will only show a static view of the active totalizer.

3.1.2.- Read mode

This mode is activated by pressing and holding down the read button (long press). Navigation within the same level will be cyclic.

This mode uses a tree structure of screens, organized into three hierarchical levels, through which the information is accessed.

The diverse information that can be displayed in the Read mode will be browsed through using the Read button, and short and/or long presses of this same button.

Screen L11 (CONTRACT 1: CURRENT)

This is the screen that shows the information about the current values of contract 1. Upon entering this menu, two data viewing options appear: absolute values and incremental values.

The ABSOLUTE option (Abs) provides us with the absolute active and reactive energy values, as well as the power excesses and maximum demands.

The INCREMENTAL option (Inc) provides us with the incremental active and reactive energy values since the last billing closure, as well as the power excesses and maximum demands. If no option is selected, the Absolute values will be displayed by default following the next press of the button.

On both of the screens, only the active information will be displayed, i.e. if certain tariffs or registers, such as the power excesses or maximum demands, have not been activated, no information regarding them will appear on the screen. Shown below are the codes for the Absolute values:
