1 General Description

MULTICAL

®

801 is an energy meter with many applications. In addition to being an accurate and reliable mains supplied heat meter MULTICAL

®

801 can also be used for:



Energy metering independent of supply voltage interruptions



Cooling metering in water-based systems



Bifunctional heat/cooling metering in separate registers



Leak surveillance of heat and cold water installations



Power and flow limiter with valve control



Data logger



Data communication



Analog 0/4…20 mA outputs

In designing MULTICAL

®

801 we have attached great importance to flexibility through programmable functions and plug-in modules in order to secure optimum use in a wide range of applications. In addition, the construction makes it possible to update previously installed MULTICAL

®

801 via the PC-program METERTOOL.

This technical description has been written with a view to enabling operations managers, meter installers, consulting engineers and distributors to utilize all functions comprised in MULTICAL

®

801. Furthermore, the description is directed to laboratories performing tests and verification.

MULTICAL

®

801 is based on the platform used for MULTICAL

®

601. However, many extra facilities such as back illuminated display, back-up of energy metering during power failure, extra communication channels and the option of four analog outputs have been added.

PROG, A-B-CCC-CCC

The meter’s legal parameters are determined by the Prog, which cannot be changed without breaking the verification seal. This means that the change must be made by an accredited laboratory.

The

A-code

states whether flow sensor (V1) is installed in forward or return pipe. As the volume of water increases with temperature, the calculator must correct for the installation form in question. Wrong programming or installation results in measuring errors. Further details concerning installation of flow sensor in flow and return in connection with heat and cooling meters appear from section 5.1.

The

B-code

indicates the measuring unit used for the energy register. GJ, kWh or MWh are the most used units, whereas Gcal are only used in a few countries outside the EEA.

The

CCC-code

states the calculator’s adaption to a specific flow sensor type to the effect that calculating speed and display resolution are optimized for the selected flow sensor at the same time as type approval regulations about minimum resolution and maximum register overflow are obeyed. The CCC-codes are divided into smaller tables in order to obtain a faster overview.

CCC(V1) states the CCC-code of the flow sensor connected to flow sensor input V1 on terminals 9-10-11 (or 10B-

11B). In most applications this is the flow sensor used for energy calculation.

CCC(V2) states the CCC-code of a possible extra flow sensor, which can be connected on terminals 9-69-11 (or

69B-79B). If V2 is not used, CCC(V2) is equal to CCC(V1). For leak surveillance CCC(V2) must be equal to CCC(V1).

CCC-TABLE FOR MULTICAL

801

The CCC-tables are divided into quick codes (CCC=4XX and 1XX) for electronic meters, e.g. ULTRAFLOW

, and slow codes for e.g. reed contacts (CCC=0XX).

CCC= 4XX Electronic meters with quick and bounce-free pulses as well as info codes for ULTRAFLOW

X4

Max. pulse frequency: 128 Hz

Max. integration frequency: 1 Hz

CCC= 1XX Electronic meters with quick and bounce-free pulses

Max. pulse frequency: 128 Hz

Max. integration frequency: 1 Hz

CCC= 0XX Mechanical meters delivering slow pulses with bounce (flow sensor type "L")

Max. pulse frequency: 1 Hz

Max. integration frequency: 1 Hz

Max. integration frequency is 1 Hz for all types. The CCC-codes have been so composed that qs+20% (or

Qmax+20%) does not exceed an integration frequency of 1 Hz.

Example: CCC=107 (applying to a qp 1.5 m

3

/h meter) : 1 Hz integration frequency is obtained at q = 3.6 m

3

/h.

EN 1434 comprises requirements to the resolution and register size of the energy indication. MULTICAL

®

801 fulfils these requirements provided that it is connected to one of the below-mentioned flow sensor sizes:

6 Calculator functions

6.1

Energy calculation

MULTICAL

801 calculates energy on the basis of the formula stated in EN 1434-1:2007, which uses the international temperature scale issued in 1990 (ITS-90) and the pressure definition of 16 bar.

In a simplified form the energy calculation can be expressed as: Energy = V x



x k.

The calculator always calculates energy in

Wh

, and then converts the value to the selected measuring unit.



801 can calculate various different energy types. Both in the display and during data reading each energy type is uniquely defined, e.g.

Heat energy: E1 = V1(T1-T2)k Cooling energy: E3 = V1 (T2-T1)k

k

is the heat coefficient of water which is calculated on the basis of the formula stated in EN 1434-1:2007

Calculator with two flow sensors

MULTICAL

801 can be used in various applications with two flow sensors, e.g. leak surveillance or open systems. When two ULTRAFLOW

are direct connected to one MULTICAL

801, a close electric coupling between the two pipes ought to be carried out as a main rule. If the two pipes are installed in a heat exchanger, close to the flow sensors, however, the heat exchanger will provide the necessary electric coupling.

Electric coupling

Forward and return pipes are closely electrically coupled

No welded joints occur

In installations where the electric coupling cannot be carried out, or where welding in the pipe system can occur, the cable from one ULTRAFLOW

must be routed through a Pulse Transmitter with galvanic separation before the cable enters MULTICAL

801.

Forward and return pipes are not necessarily closely coupled

Electric welding

can occur

*)

Electric welding must always be carried out with the earth pole closest to the welding point. Damage to meters due to welding is

T1). Temperature sensor T1 (with a red type sign) must be installed in the hydraulic forward pipe whereas T2 is installed in the return pipe.

The temperature point “T1 limit” is used as a ”filter” for cooling measurement in the way that only cooling is measured when the current forward temperature T1 is below T1 limit.

T1 limit is configurable in the temperature range 0.01…180.00

C. T1 limit is configured via

METERTOOL.

In combined heat/cooling meters T1 limit ought to correspond to the highest occurring forward temperature in connection with cooling, e.g. 25

C. If the meter is to be used for ”purchase and sale of heat”, T1 limit is adjusted to 180.00

C, which cancels the T1 limit function.

The change between heat and cooling measurement involves no hysteresis (

T1 limit = 0.00K).

Flow measurement V1 and V2

MULTICAL

801 calculates current water flow according to two different principles depending on the connected flow meter type:

Quick volume pulses (CCC

100)

-

-

The current water flow for quick volume pulses, without average determination, is calculated as the number of volume pulses per 10 sec. multiplied by the scaling factor.

q = (Imp./10 sec. x flow factor)/65535

l/h

or

m

/h

Example:

ULTRAFLOW qp 1.5 m

/h with 100 imp./l (CCC=119), flow factor = 235926

Current water flow = 317 l/h, corresponding to 88 Imp./10 sec.

q = (88 x 235926)/65535 = 316.8 which is displayed as 316

l/h

Current water flow in V1

Slow volume pulses (CCC = 0XX)

The current water flow of slow volume pulses (typically from flow meters with reed contact) is calculated without average determination as a scaling factor divided by the duration between two volume pulses.

q = flow factor/(256 x period of time in sec.)

/h, which corresponds to 36 sec. of the duration between 2 pulses

q = 230400 /(256 x 36) = 25 which is displayed as 2.5

l/h

V1 and V2 must be the same type (either quick (CCC

100) or slow (CCC=0XX)) but can have different qp-codings

(CCC).

The actual flow rate on the display will be shown a ”0”, when the period between pulses exceed 15 min.

Min. and max. flow and power, V1

MULTICAL

801 registers minimum and maximum flow and power on both monthly and yearly basis. The complete registration can be read via data communication. Furthermore, a few monthly and yearly registers can be read from the display, depending on the selected DDD-code.

The min. and max. registrations include the following flow and power values with indication of date:

Type of registration Max. data Min. data Yearly data Monthly data

Max. this year (since latest target date)

Max. yearly data, up to latest 15 years

Max. monthly data, up to latest 36 months

Min. this month (since latest target date)

 

Min. monthly data, up to latest 36 months

 

All max. and min. values are calculated as biggest and smallest average of a number of current flow or power measurements respectively. The average period used for all calculations can be selected in the interval 1...1440 min. in 1 min. leaps. 1.440 min. = 24 hours).

Average period and target date must be stated in the order, or be reconfigured by means of METERTOOL. In the absence of other information with the order, the average period is set to 60 min. and the target date to the standard value applying to the delivery code used.

At the end of a year and a month the max. and min. values are saved in the data logger, and the current max. and min. registers are “reset” according to the selected target date and the meter’s internal clock and calendar.

”Reset” is made by setting the max. value to zero and the min. value to 10000,0 kW at e.g. CCC=119.

If the max. or min. registration is used for accounting purposes, we recommend that the clock setting is checked in connection with the installation as well as once a year. Furthermore, the back-up battery of MULTICAL

Temperature measurement

MULTICAL

801 is fitted with a high-resolution analog/digital converter which measures the temperatures T1, T2 and T3 with a resolution of 0.01

C. The same measuring circuit is used for all three temperature inputs in order to obtain the lowest possible measuring error of the temperature difference. Prior to each temperature measurement the internal measuring circuit is automatically adjusted on the basis of built-in reference resistors at 0

C and 100

C respectively. Very accurate measurements and an almost immeasurable long-term stability is hereby obtained.

Current T1

MULTICAL

801 measures all temperatures every 10 seconds if supply voltage is connected. If the supply voltage is disconnected and the meter is driven by the backup battery, temperature measurements are carried out with every integration (energy calculation), not at shorter intervals than 10 sec. however.

The temperature range of the measuring circuit is 0.00

C…185.00

C. For disconnected temperature sensor

200.00

C is shown and for short-circuited temperature sensor 0.00

C is displayed. In both cases the info code for sensor error will appear.

In order to reduce the influence of hum which can e.g. be picked up in long sensor cables, double measurements with a timing difference of half a period of time are carried out, and the average of the two measurements is the temperature measurement used for calculation and the one displayed. The hum suppression is optimized to either 50 Hz or 60 Hz depending on the selected country code.

6.8.1

Measuring current and power

Measuring current is only sent through the temperature sensors during the short duration of the temperature measurement. The effective power which is deposited in the sensor elements is thus very small, and its influence on the self-heating of the temperature sensors is typically less than 1/1000 K.

Transport mode

When the meter leaves the factory it is in transport mode, whereby the info codes are active in the display only, not in the data logger. This prevents ”infoevent” from counting during transportation and non-relevant data from appearing in the info logger. When the meter has accumulated the volume register the first time after the installation, the info code automatically becomes active.

Tariff functions

MULTICAL

801 has 2 extra registers TA2 and TA3, which can accumulate heat energy (EE=20 accumulates volume) parallel with the main register, based on a programmed tariff condition. Irrespective of the selected tariff form, the tariff registers are named TA2 and TA3 in the display. The tariff function can only be used for heat energy

(E1).

The main register is always accumulated as it is considered legal billing register, no matter the selected tariff function. Tariff conditions TL2 and TL3 are monitored with each integration. If the tariff conditions are fulfilled, consumed heat energy is accumulated in either TA2 or TA3 parallel with the main register.

Leak surveillance

6.13.1

District heating system

The leak surveillance system is primarily used for direct connected district heating systems, i.e. systems without exchangers between the district heating network and the heating system of the house. The surveillance equipment consists of two ultrasonically based water meters placed in forward and return pipe respectively as well as temperature sensors in both pipes. Furthermore the electronics unit MULTICAL

801, which calculates the heat energy and monitors the mass difference (temperature corrected volume) which can be found between forward and return pipe.

If a difference that exceeds 20% of the measuring range (corresponding to 300 l/h for a single-family house) is registered, an alarm will be sent within 120 sec. via remote communication.

Small leaks from 15 kgs/h and upwards for qp 1.5 m

District heating burst

Every 30 seconds the current flow of the forward pipe is compared to that of the return pipe. If the difference exceeds 20% of the nominal flow at four successive measurements (120 sec.), info = 00512 is set and a ”burst alarm” is sent via remote communication.

6.13.3

Cold water systems

In addition to the above-mentioned functions MULTICAL

801 can be connected to the pulse signal from the cold water meter of the house. It can thus monitor the cold water consumption. Possible running cisterns, untight heating spirals of tap water tanks or other untightnesses will cause pulses to be received from the cold water meter 24 hours a day.

If MULTICAL

801 does not register e.g. at least one continuous hour/day without pulses from the water meter, this implies a leakage in the water system and an alarm will be sent via remote communication.

6.13.4

Receipt of alarm messages

When the meter has registered a leak or burst it sends an alarm message to a receiving station, where incoming alarms are processed according to an encoded action pattern which is determined for each customer, e.g. starting with an SMS message to the customer’s mobile phone parallel with the heating station on guard receiving the message. Regular data readings from MULTICAL

801 to receiving station/control centre ensure that defective remote readings, if any, are detected.

TECHNICAL DESCRIPTION MULTICAL

801

6.13.5

Surveillance, but no automatic blocking

The leak surveillance system is based on installation at a big number of private district heating customers.

Normally the individual district heating stations install and maintain leak surveillance as an integral part of the compulsory heat metering of all district heating customers in their area. Therefore, the individual private district heating customers need not take care of maintenance or other task of technical character in connection with the installed leak surveillance system, and the surveillance system must not involve increased risk of erroneous closing, which may lead to frost burst. Due to this fact the stability and reliability of the complete system must make 12 years operation without further maintenance possible. As neither thermically or electrically activated closing valves can be expected to have so long a lifetime it is not possible to use automatic closing.

6.13.6

First day after reset

The first day after the installation (the meter having been without supply voltage) no info codes will be sent or alarms set in case of a calculated district heating or cold water leak.

This limitation has been introduced in order to avoid erroneous alarms due to the installation and the shortened measuring period.

The alarm function can be tested via remote communication by pressing both pushbuttons at a time until “Call” is displayed.

Reset functions

6.14.1

Resetting the hour counter

The operating hour counter can be reset in connection with e.g. change of backup battery.

As the hour counter is often used to check whether the meter has been in operation during the whole billing period (e.g. 1 year = 8760 hours) the district heating supplier must always be informed, inwhich meters the hour counter has been reset

In order to reset the operating hour counter switch off the supply voltage and disconnect the backup battery, then wait until the display goes blank.

Connect the backup battery whilst activating the top pushbutton for min. 10 sec. until e.g. energy is displayed.

Do not forget to switch on the supply voltage again. The operating hour counter has been reset.

Note: Resetting the hour counter involves that the meter’s internal clock is initialized to 00:00:00 and

2000:01:01, and it is therefore necessary subsequently to adjust the clock by means of hand-held terminal or PC with METERTOOL.

6.14.2

Resetting data loggers

Separate reset of data loggers, info loggers, max. & min. logger (without resetting the legal registers) can only be carried out by means of METERTOOL. See paragraph 14 for further information.

6.14.3

Reset of all registers (total reset)

All legal and non-legal registers, including all data loggers, info logger, max. & min. logger can be reset by means of METERTOOL or a short-circuit pen if the verification seal is broken and the internal “total programming lock” is short-circuited.

Important! As the verification seal is broken, this reset must be carried out by competent laboratories/utility companies with authorization to reseal the meter!

The following registers are reset: All legal and non-legal registers, including all data loggers, info logger, max. and min. logger (max. values are set to zero, whereas min. values are set to 100000).

Note: ”Date” is after reset set to 2000.01.01 and subsequently changed to current date/time from the PC used for the task. Therefore, do not forget to check correct date/time (technical normal time = ”winter time”) of the PC before starting the reset function via METERTOOL.

Reset of all registers (with short-circuit pen)

The supply voltage (230 VAC or 24 VAC) is switched off, but the backup battery must be in working order. A shortcircuit pen (type: 66-99-278) is used to break the seal and short-circuit the two contact points for approx. 10 sec., until CLR is displayed.

Figure 3

The short-circuit pen functions in >back-up mode< as

801 can be read by means of an SMS. In order to do so, a GSM-module fitted with a SIM-card must be mounted in the meter (see paragraph 11.1.5). You send an SMS from a mobile phone direct to the meter.

Subsequently, you receive a reply with the following values:

Acc. energy: [kWh], [MWh], [GJ] or [Gcal]

Current power: [kW] or [MW]

Hour counter

Meter number

It is also possible to read the modem’s signal strength by means of an SMS. You receive a reply with the modem’s current signal strength on a scale of 0 to 31, the best value being 31. The signal strength must be minimum 12.

See the examples on the next page.

7 Flow meter connection

MULTICAL

801 can be used with up to 4 pulse inputs, of which V1 and V2 are used for energy calculation and leak surveillance, whereas VA and VB are used to accumulating pulses from e.g. cold water meters and electricity meters.

V1 and V2 can either be used for quick pulses (CCC

100) or slow pulses (CCC = 0XX). Quick and slow pulses cannot be used at a time.

7.1

Volume inputs V1 and V2

MULTICAL

801 can be connected with one or two flow meters, depending on the required application. Typical heating installations with one flow meter is always connected to V1, no matter if this flow meter is installed in forward or return pipe.

Almost all available flow meter types with pulse output can be connected as the standard connection circuit can receive pulses from both electronic and mechanical meters.

7.1.1

Flow meter with transistor or FET output

The signal transmitter is normally an optocoupler with transistor or FET output. V1 is connected to terminals 10(+) and 11(-), V2 is connected to terminals 69(+) and 11(-). Terminal 9 is not used in this application.

The leak current of transistor or FET output must not exceed 1

A in OFF-state and it must be max. 0.4 V in ONstate.

A suitable CCC-kode with the same number of imp./litre as the flow sensor must be selected and for this flow meter type the CCC-code must be CCC

100.

Example: CCC=147 is suitable for an electronic meter with 1 imp./litre and qp 150 m

3

/h.

7.1.2

Flow meter with reed contact output

The transmitter is a reed contact, which is normally mounted on vane wheel and Woltmann meters, or a relay output from e.g. a magnetic inductive flow sensor. V1 is connected to terminals 10(+) and 11(-), V2 is connected to terminals 69(+) and 11(-). Terminal 9 is not used in this application.

The leak current must not exceed 1

Use of Pulse Transmitter between ULTRAFLOW

®

and MULTICAL

®

In general it is permissible to use up to 10 m cable between MULTICAL

®

and ULTRAFLOW

®

. If longer cable is required, a Pulse Transmitter can be inserted between ULTRAFLOW

®

and MULTICAL

®

. In this way the cable length can be extended up to 50 m.

When a Pulse Transmitter is used between ULTRAFLOW

®

and MULTICAL

®

, volume pulses from the flow meter will be transferred to the calculator. However, the calculator is unable to data communicate with the flow meter. In order to avoid erroneous info codes it is, therefore, necessary to deselect the info codes, which are based on data communication between MULTICAL

®

and ULTRAFLOW

®

54 (Info = 16-1024-2048-128-4096-8192-16384-32768).

The above-mentioned info codes can be deselected by means of the PC-program METERTOOL, either by changing from CCC-code 4xx to 1xx, or by using the ”Info code setup” function under ”Utility”. See paragraph 14.2.3 Info code setup.

Pulse outputs VA and VB

In addition to pulse inputs V1 and V2, MULTICAL

801 has two extra pulse inputs, VA and VB, for collection and remote accumulation of pulses from e.g. cold water meters and electricity meters. The pulse inputs are physically placed in ”Module 1” like e.g. in ”M-Bus + pulse inputs” which can be placed in the connection bracket, but accumulation and data logging of values is carried out by the calculator.

Pulse inputs VA and VB function independently of the other inputs/outputs and are therefore not included in any energy calculation either.

The two pulse inputs are identically constructed and can be individually set up to receive pulses from water meters with max. 1 Hz or pulses from electricity meters with max. 3 Hz.

Configuration for correct pulse value has been carried out from the factory on the basis of order information or is configured by means of METERTOOL. See paragraph 3.6 concerning configuration of VA (FF-codes and VB (GGcodes).

MULTICAL

801 registers the accumulated consumption of the meters connected to VA and VB and saves the counter values every month and every year on target date. In order to facilitate the identification during data reading it is also possible to save the meter numbers of the two meters connected to VA and VB. Programming is carried out with METERTOOL.

The registration, which can both be read from the display (selecting a suitable DDD-code) and via data communication, includes the following as well as date indication of yearly and monthly data:

MULTICAL

801 is in standard version fitted with 4-wire sensor inputs for all three inputs, T1-T2-T3. Mostly only relatively short temperature sensor lengths are needed for small and medium-size heat meters, which means that

2-wire sensor sets can be used with advantage.

Figure 14

Connection of 2-wire sensors by means

Cable lengths and cross sections of the two sensors which are used as temperature sensor pair for a heat meter must always be identical, and cable sensors must neither be shortened nor extended.

The limitations connected to the use of 2-wire sensor sets according to EN 1434-2 appear from the table below.

801 has a ”real” 4-wire construction, which uses two conductors for measuring current and the two conductors for measuring signal, which means that the construction is in theory uninfluenced by long sensor cables. In practice cables ought not to be longer than 100 m and we recommend the use of 4 x 0.25 mm

Pocket sensors

The Pt500 cable sensor is constructed with 2-wire silicone cable and closed with a D 5.8 mm shrunk on stainless steel tube which protects the sensor element.

The steel tube is mounted in a sensor pocket (immersion pipe) which has an inner diameter of 6 mm and an outer diameter of 8 mm. Sensor pockets are available with R½ (conical ½”) connection in stainless steel i lengths of

65, 90 and 140 mm. The sensor construction with separate immersion pipe permits replacement of sensors without having to switch off the flow. Furthermore, the wide range of immersion pipe lengths ensures that the sensors can be mounted in all existing pipe dimensions.

The plastic tube on the sensor cable is placed opposite the sealing screw and the screw is tightened lightly by hand before sealing.

Pt500 short direct sensor pair

The Pt500 short direct sensor has been constructed according to the European heat meter standard EN 1434-2.

The sensor has been designed for direct mounting in the measuring medium, i.e. without sensor pocket, whereby a very fast response to temperature changes from e.g. domestic water exchangers is obtained.

The sensor is based on two-wire silicone cable. The sensor pipe is made of stainless stell and has a diameter of 4 mm at the point where the sensor element is placed. Furthermore, it can be direct mounted in many flow sensor types which reduces the installation costs.

The sensor can be mounted in special T-sections which are available for ½”, ¾” and 1” pipe installations.

In addition, the short direct sensor can be mounted by means of a R½ or R¾ for M10 nipple in a standard 90

9.1

Pulse outputs CE and CV [16-19]

MULTICAL

®

801 has pulse outputs for energy and volume pulses respectively. CE on terminals 16-17 releases one pulse per least significant digit in the energy count of the display and CV on terminals 18-19 releases one pulse per least significant digit in the volume count of the display.

For CCC codes with 8-digit counter (e.g. CCC=206) energy pulses (GJ) and volume pulses (m3) will be generated with every least significant digit but one.

If a higher resolution of pulse outputs is required, a high resolution CCC code must be selected.

The pulse outputs are passive, optoisolated and tolerate 30 VDC and 10 mA. If active pulse outputs are required, the internal supply on terminals 97A-98A can be used.

Passive pulse outputs connected via external supply Active pulse outputs connected via internal supply

By means of the PC-programm METERTOOL you can choose between 32, 100 and 247 msec. in addition to the option of pulses for combined heat/cooling measurement (CE- and CV-).

9.2

Analog outputs [80-87]

MULTICAL

®

801 is available with 4 analog outputs. The outputs are active 0-20 mA or 4-20 mA, can be loaded with 0…500

and are optoisolated in relation to the supply. The 4 analog outputs, however, are not mutually isolated. All values of the four analog outputs are updated every 10 seconds.

Example of configuration of the analog outputs:

The analog outputs can be configured as power, flow (V1, V2), T1, T2, T3 or T1-T2, and also the measuring range can be configured. All relevant configurations can be set up from the factory or on site by means of METERTOOL.

After reconfiguration of the analog outputs the meter must be reset. A reset can be effected in two different ways:

1) Switch off the mains supply and remove the plug to the back-up battery. The new values will not be saved in the meter’s memory until back-up battery and mains supply have been reconnected.

2) By means of METERTOOL a ”normal reset” is carried out under ”UTILITY

Reset”. After this the new values have been stored in the meter’s memory.

Danish regulations for the connection of mains operated meters

Installation to mains connected equipment for registration of consumption (Text from The Danish National

Safety Board, 2004-12-06)

The consumption of energy and resources (electricity, heat, gas and water) of the individual consumer is to an increasing extent registered by electronic meters, and often equipment for remote reading and remote control of both electronic and non-electronic meters is used.

General regulations for carrying out installations must be observed. However, the following modifications are permitted:

If meter or equipment for remote reading or remote control are double-isolated it is not necessary to draw the protective conductor all the way to the connection point. This also applies if the connection point is a plug socket provided that it is placed in a canning which is sealable or can be opened with key or tool only.

If meter or equipment for remote reading and remote control, which is connected to a safety transformer mounted in the panel and direct connected to the branch conductor, is used, no on-off-switch or separate overcurrent protection in either primary or secondary circuit is required provided that the following conditions are fulfilled:

The safety transformer must either be inherently short-circuit-proof or fail-safe

The conductor of the primary circuit must be either short-circuit-protected by the overcurrent protection of the branch conductor or short-circuit safely drawn.

The conductor of the secondary circuit must have a cross section of at least 0.5 mm² and a current value which exceeds the absolute maximum current deliverable by the transformer

It must be possible to separate the secondary circuit by separators or it must appear form the installation instructions that the secondary circuit can be disconnected at the transformer’s terminals

General information

Work on the fixed installation, including any intervention in the group panel, must be carried out by an authorized electrician.

It is not required that service work on equipment comprised by this message as well as connection and disconnection of the equipment outside the panel is carried out by an authorized electrician. These task can also be carried out by persons or companies, who professionally produce, repair or maintain equipment if only the person carrying out the work has the necessary expert knowledge.

12.1

MULTICAL

801 Data Protocol

Internal data communication in MULTICAL

801 is based on the Kamstrup Meter Protocol (KMP) which partly provides a quick and flexible reading structure and partly fulfils future requirements to data reliability.

The KMP protocol is used in all Kamstrup consumption meters launched in 2006 and later. The protocol is used on the optical eye and via plug pins for the modules. Thus, modules with e.g. M-bus interface use the KMP protocol internally and the M-bus protocol externally.

The KMP protocol has been constructed to handle point to point communication in a master/slave system (e.g. a bus system) and is used for data reading of Kamstrup energy meters.

Software and parameter protection

The meter’s software is implemented in a ROM and cannot be changed, neither deliberately nor by mistake.

The legal parameters cannot be changed via data communication without breaking the legal seal and short circuiting the ”total programming lock”.

Software conformity

Software checksum, based on CRC16, is available via data communication and in the display.

Integrity and authenticity of data

All data parameters include type, measuring unit, scaling factor and CRC16 checksum.

Every produced meter includes a unique identification number.

Two different formats are used in the communication between master and slave. Either a data frame format or an application acknowledgement format.

A request from master to slave is always sent in a data frame.

The response from the slave can either be sent in a data frame or as an application acknowledgement.

The data frame is based on the OSI model using the physical layer, the data link layer and the application layer.

Number of bytes in each field

Field designation

1 1 1 0-? 2 1

Start byte Destination address

CID Data

OSI – layer Application layer

Data link layer

Physical layer

The protocol is based on half duplex serial synchroneous communication with setup: 8 data bits, no parity and 2 stop bits. The data bit rate is 1200 or 2400 baud. CRC16 is used in both request and response.

Data is transferred byte for byte in a binary data format, of which the 8 data bits represent one byte of data.

Byte Stuffing is used for extending the value range.

General information

It is important to be familiar with the calculator’s functions before starting programming.

There are two programming options ”Partial programming” and ”Total programming”.

”Partial programming” does not allow change of coding which is important to energy calculation, e.g. Type number and Program number.

By means of ”Total programming” it is possible to change the remaining values too. Programming is only possible if the internal programming lock is closed (short-circuit pen 66-99-278).

In order to carry out verification the jumper connection must remain the same throughout the verification.

It is not possible to change the serial number as it is a unique number allocated to the meter during production.

”V2(CCC)”, ”T1”, ”T2” and ”Max T1 for cooling” can be disabled, depending on the meter type in question.

Partial/Total programming

The program is self-explanatory as to most coding numbers (see text in “combo-boxes”), further details can be found in the respective paragraphs of the technical description.

Verification with METERTOOL MULTICAL

801

14.3.1

General information

Verification of MULTICAL

801 requires verification equipment and verification data must be entered into the

METERTOOL program.

14.3.2

Verification equipment

Verification equipment, e.g. item no. 66-99-370 for verification of 67-F/K (4-W/Pt100) or item no. 66-99-371 for verification of 67-G/L(4-W/Pt500) is used for verification of calculator MULTICAL

801. The verification includes energy verification of ”E1” and ”E3”, test of volume inputs ”V1”, ”V2”, ”VA” and ”VB” as well as test of temperature input ”T3”.

Different temperatures are simulated for the two sensor inputs ”T1” and ”T2”. Together with the volume simulation (autointegration) these temperatures form the basis of the verification of the energy calculation.

The equipment was primarily constructed for use in laboratories, which test and verify heat meters, but can also be used for performance testing the meter.

The computer program ”METERTOOL MULTICAL

801” is used for configuration, test and verification.

In order to carry out verification the programming lock must be closed throughout the verification (see paragraph

14.2.1 General)

The verification equipment for MULTICAL

801 includes USB interface (item no. 66-99-098) as well as corresponding driver software. During installation this interface creates a virtual COM port which figures as an optional COM port of the METERTOOL MULTICAL

801 software in the computer. As the virtual COM port only exists when the equipment is connected, the verification equipment

must

be connected to the computer before the program ”METERTOOL MULTICAL

801” is started. Furthermore, the verification equipment requires mains supply via the included mains adapter.

Verification does no apply to temperature and flow sensor(s).

The verification equipment is available in three different types, depending on the MULTICAL

801 type used and the temperature points to be tested. The 2 most common type can be seen below.

Function

Verification equipment, e.g. item no. 66-99-370 or 66-99-371 is mounted in a standard MULTICAL

base and includes battery, verification PCB with connection terminals, interface for calculator, microprocessor, control relays and precision resistors.

The connection between verification equipment and MULTICAL

801 consists of a 14-pole test connector.

During test the calculator is supplied by the meter’s main supply. The verification PCB is powered with 12 VDC by the enclosed external mains adapter. The microprocessor simulates volume based on pulse frequency and the number of pulses per test point selected in the computer program. Temperature simulation is obtained by means of fixed precision resistors, which are automatically changed via relays controlled by the microprocessor.

After the test the computer reads registers in the calculator and compares the values to the calculated values.

The calibration result in percentage for each test point can be stored in the computer under the serial number of the tested MULTICAL

801 to be printed out later on a test certificate.

Verification data

The first time METERTOOL and the verification equipment is used a number of calibration data must be entered into the menu ”Verification” under ”Settings” in the METERTOOL program. Calibration data is electronically included in the verification equipment (also enclosed with the verification equipment as a certificate on paper). In order to transfer calibration data from the equipment to the program select ”Verification” from the menu

”Settings” and activate ”Read”. Calibration data is now transferred to and saved in the METERTOOL program.

The calibration data of the equipment and the program verification data are compared every time verification equipment is connected in order to secure that verification data is updated if the calibration data of the equipment have been changed. For instance this can be due to recalibration of verification equipment.

Calibration data of the verification equipment can be maintained by changing verification data in the program

METERTOOL and clicking on “Write” these new data into the equipment. In order to avoid unintentional change of calibration data ”Write” is protected by a password, which can be obtained from Kamstrup A/S.

Calibration data include test points, permissible error, uncertainty, ambient temperature (fixed value) and number of integrations per test.

Having entered verification data, the program automatically calculates the true k-factor in accordance with the formula of EN 1434 and OIML R75:2002.

Choice of data period from/to:

Activate ”Read” to collect selected data from the meter

Calculation with read values:

Graph/table of calculation:

Possible/saved calculations:

Choice of required data registers:

Graph(s)/table of data from selected registers:

After read-out non-selected data registers become grey and cannot be used for further processing/analysis. In order to read all data, select all values by clicking on ”Select All” .

When read-out has been completed the program automatically asks whether the data should be saved. We recommend you to save the read-outs to make it possible to reopen the data later for further analysis or documentation.

Additional functions can now be selected for the read data. By means of ”

Calculation

” individual calculations can be carried out, and graphs/tables with the values appear by activating ”Show Graph”. If you want to save the calculation forms for reuse, select ”Add to” and the function is added to ”Calculated Registers”.

In order to carry out a new data reading activate “Clear”, and select a new period and new data registers.

16 Troubleshooting

MULTICAL

801 has been constructed with a view to quick and simple installation as well as long and reliable operation at the consumer.

Should, however, an operating problem with the meter occur, the table below can be used for troubleshooting.

Repairing the meter, if needed, we recommend only to replace battery, temperature sensors and communication modules. Alternatively the whole meter ought to be replaced.

Major repairs must be made by Kamstrup A/S.

Before sending in the sensor for repair or check, please use the error detection table below to help you clarify the possible cause of the problem.
