CIRWATT B 500 2�1 - METER VERSIONS The following table shows all the possible options that are available for the CIRWATT Type B. This table is generic, meaning that some versions listed in it may not currently be available Table 3: Meter versions�...
CIRWATT B 500 2�2 - METROLOGY The metrological features for the CIRWATT type B Three-phase (TBT) are: • The current sensor is of the current transformer type. • Range of currents: Table 4: Range of currents� Range of currents Model 505 (... / 5A) Active Class C (0�5s)
CIRWATT B 500 2�5 - BUILD CHARACTERISTICS 2�5�1 - GENERAL The meter has a class-II protective insulating enclosure and double insulation. As specified in Directives 2002/96/EC and 2002/95/EC, none of the materials or substances specified therein are used. The materials used are fire retardant, halogen free and emit low quantities of opaque, toxic or corrosive fumes.
CIRWATT B 500 2�5�6 - TERMINAL COVER (DEPENDING ON VERSION) The meters have an opaque cover over the top of the terminal box and the fixing screws. The meter has a sensor that detects the opening and closing of the terminal cover. This detection is always enabled, even if the meter is not powered.

CIRWATT B 500 the active quadrant (Q1,Q2,Q3,Q4) L1+L2+L3+, indicates the presence of voltage on each phase with its corresponding sing of intensity: "+" is used to show the power absorbed from the mains. "–" is used to show the power transferred to the mains.
CIRWATT B 500 2�7 - VERIFICATION PULSES The device has 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, and is 20,000 imp/kWh (kVArh).
2�12�3 - VERSION WITH LEAKAGE CURRENT MEASUREMENT The meter will have an input for connecting an external transformer of the Circutor WN series, which will allow reading the differential current (leakage) present in the installation.
CIRWATT B 500 2�13 - REAL-TIME CLOCK The meter has a real-time clock capable of keeping the date and time with a drift of less than 0.5 seconds/day, as specified in the UNE EN 61038 standard. The clock maintains this accuracy whether it is powered from the mains or by its own battery.
CIRWATT B 500 2�19�1 - NUMBER AND ALLOCATION OF CONTRACTS The meter has three contracts defined. 2�19�2 - CONTRACT PARAMETERS A parameter is considered to be defined if it has an assigned value, and undefined if it is blank. A parameter that is not used cannot have any value assigned from previous parameterisations, and thus it will remain undefined.
CIRWATT B 500 Type of day The type of day refers to the set of tariff periods allocated to each of the 24 hours in a day. Each type of day is identified using a number starting with 1 and increasing by one for successive types.
CIRWATT B 500 of closing can affect one or more active contracts. An extraordinary immediate closing is automatically done in the following cases: Change in transformation ratio. Affects every contract. Change of power contracted by period. Affects the modified contract.
CIRWATT B 500 If the group of power is modified, it may also be necessary to modify the group of seasons and types of days beforehand, in order to maintain consistency. The groups are: Holidays (up to 15). Power. Automatic billing closing date.
CIRWATT B 500 If more than one contract has been defined and is active and one of them is deleted and the rest are maintained, at the time of deletion, the billing for the contract to be deleted is closed out. From that moment on, the information pertaining to the deleted contract is erased and no information on it can be displayed, except for that pertaining to the closed billing periods that may exist.
CIRWATT B 500 2�27 - DAYLIGHT SAVING TIME The meter – analyser automatically changes the official time. If the device is without power at the time of the change, the change will take place when power is restored and the device is initialised.
CIRWATT B 500 Sealable button Seal transformation relations / programming Manufacturer seal (under the thread cover) Wire cover lid seal Figure 2:Seals� 2�29 - MEASUREMENT VALIDATION CRITERIA The energy, maximeter and excess power records will be invalidated if a series of events occur that indicate that any of their values have been altered.
CIRWATT B 500 2�29�4 - SUPPLY FAILURE IN AT LEAST ONE PHASE The measurement for the period in which the failure occurred is invalidated, IV = 1. 2�30 - APPLICABLE REGULATIONS The CIRWATT Type B is based on the following standards: EN 50470-1:2006 - Electricity metering equipment (a.c.) -- Part 1: General requirements, tests and test...
