Page 28: Display Code >Ddd
MULTICAL® 603 3.2.4 Display code >DDD< MULTICAL® 603 has 4 display loops; USER, TECH, SETUP and TEST. The TECH loop contains all display readings, with the exception of logged values and the differential registers, and this loop is not configurable. USER loop, however, is configurable and can be adapted to customer requirements by means of the DDD code (display code). As a minimum, the USER loop comprises the meter’s legal readings. The meter’s legal readings, e.g. energy and volume reading, are basically displayed as 7‐digit values. The display readings can be configured to 8‐digit values via the DDD code. Please contact Kamstrup for further details. The first digits of the three‐digit DDD‐code define the meter type comprised by the DDD‐code in question. The table shows examples of a number of DDD‐codes within each meter type. In the table,”1” indicates the first primary reading, whereas e.g. ”1A” is the first secondary reading. The display automatically returns to reading “1” after 4 minutes. Contact Kamstrup A/S for information about available display codes.

Page 32: Tariffs >Ee
MULTICAL® 603 3.2.5 Tariffs >EE< MULTICAL® 603 has 3 extra registers TA2, TA3 and TA4, which can accumulate heat energy or cooling energy (EE=20 accumulates volume) parallel with the main register based on pre‐programmed tariff conditions (to be stated when ordering the meter). Irrespective of the selected tariff type, the tariff registers are named TA2 TA3 and TA4 in the display. As the main register is considered the legal billing register, it is accumulated no matter the selected tariff function. Tariff conditions TL2, TL3 and TL4 are monitored at every integration. If the tariff conditions are fulfilled, consumed heat energy is accumulated in either TA2, TA3 or TA parallel with the main register. Example of power tariff (EE=11) Power (P) Integrations Three tariff conditions, TL2, TL3 and TL4, which are always used in the same tariff type, are connected to each tariff function. Therefore, it is not possible to “mix” two tariff types, except from the PQ tariff (EE=21). TA2 shows energy consumed… …above the power limit TL2 IMPORTANT: Out of consideration for backwards compatibility tariff register TA4 can be deactivated. Thus, the meter uses TA2 and TA3 only, and the tariff function works as in the previous model, MULTICAL® 602. TA4 is deactivated by setting the tariff limit TL4 at 0. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 32 ...
Page 33 If no tariff function is required, you select the set‐up EE=00. The tariff function can, however, at a later stage be activated through reconfiguration via METERTOOL HCW (see Technical description 5512‐2096). EE=11 Power‐controlled tariff If the current power (P) exceeds TL2 but is lower than or equal to TL3, energy is counted in TA2 parallel to the main register. If the current power exceeds TL3 but is lower than or equal to TL4, energy is counted in TA3 parallel to the main register. If the current power exceeds TL4, energy is counted in TA4 parallel to the main register. Accumulation in main register only P  TL2 TL3  P  TL2 Accumulation in TA2 and main register TL4  TL3  TL2 Accumulation in TA3 and main register TL4  P  TL3 P  TL4 Accumulation in TA4 and main register Setting up data, TL3 must be higher than TL2 and TL4 must be higher than TL3. The power controlled tariff is e.g. used as a basis for the individual heat consumer’s connection fee. Furthermore, this tariff type can provide valuable statistical data if the heating station considers new construction activities. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 33 ...
Page 34 Q  TL2 TL3  Q  TL2 Accumulation in TA2 and main register TL4  TL3  TL2 Accumulation in TA3 and main register TL4  Q  TL3 Accumulation in TA4 and main register Q  TL4 Setting up data, TL3 must be higher than TL2 and TL4 must be higher than TL3. The flow controlled tariff is e.g. used as a basis for the individual heat consumer’s connection fee. Furthermore, this tariff type can provide valuable statistical data if the heating station considers new construction activities. When either power or flow tariff is used you obtain an overview of the total consumption compared to the part of the consumption used above tariff limits. EE=13 t1‐t2 tariff (Θ) If the current t1‐t2 (Θ) is lower than TL2 but exceeds or is equal to TL3, heat energy is counted in TA2 parallel to the main register. If the current cooling becomes lower than TL3 but is higher than or equal to TL4, energy is counted in TA3 parallel to the main register. If the current t1‐t2 (Θ) is lower than TL4, energy is counted in TA4 parallel to the main register. Θ  TL2 Accumulation in main register only Accumulation in TA2 and main register TL3  Θ  TL2 TL4  TL3  TL2 TL4  Θ  TL3 Accumulation in TA3 and main register Θ  TL4 Accumulation in TA4 and main register Setting up tariff limits, TL3 must be lower than TL2 and TL4 must be lower than TL3. The t1‐t2 tariff can be used as a basis of weighted user charge. Low Θ (small difference between inlet and outlet temperatures) is uneconomical for the heat supplier. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 34 ...
Page 35 The inlet temperature tariff can be used as a basis for billing consumers who are guaranteed a certain inlet temperature. If the “guaranteed” minimum temperature is entered in TL4, the payable consumption is accumulated in TA4. EE=15 Outlet temperature tariff If the current outlet temperature (t2) exceeds TL2, but is lower than or equal to TL3, energy is counted in TA2 parallel to the main register. If the current outlet temperature exceeds TL3, but is lower than or equal to TL4, energy is counted in TA3 parallel to the main register. If the current outlet temperature exceeds TL4, energy is counted in TA4 parallel to the main register. Accumulation in main register only t2  TL2 TL3  t2  TL2 Accumulation in TA2 and main register TL4  TL3  TL2 Accumulation in TA3 and main register TL4  t2  TL3 t2  TL4 Accumulation in TA4 and main register Setting up data, TL3 must be higher than TL2 and TL4 must be higher than TL3.

Page 38: Pulse Inputs A And B >Ff-Gg
MULTICAL® 603 3.2.6 Pulse inputs A and B >FF‐GG< MULTICAL® 603 can have four extra pulse inputs (A1, A2, B1 and B2) which are placed on the communication modules (see paragraph 11 for further details on modules). The pulse inputs are used for acquisition and remote accumulation of pulses from e.g. mechanical water meters and electricity meters. The pulse inputs function independently of the meter itself. Therefore, they are not included in any energy calculation. The four pulse inputs are identically constructed and can be configured to receive pulses from water or electricity meters. Pulse inputs A and B are placed on selected communication modules. If the module is installed in module slot 1 of MULTICAL® 603, the inputs A1 and B1 are identified, and likewise for module slot 2; A2 and B2. Note: The pulse inputs A1 and A2 are always identically configured through the FF code, and the inputs B1 and B2 are likewise always identically configured through the GG code. Therefore, pay special attention to this when the modules are installed in the meter, so that they are installed in the correct module slot in regard to the equipment they are to be connected to.

Page 44 When the system is stable, the meter gradually returns to the 64 s. interval. MULTICAL® 603 reacts quickly to changes in the system by lowering the time interval; however, it gradually returns to the time interval of 64 s. as the system becomes stable. This is illustrated in the figure below. Integration time Thus, in adaptive mode MULTICAL® 603 measures at high resolution during periods with changes in the system requiring accurate measurements and saves battery power during periods with no changes in the thermal system. Adaptive mode is recommended for all systems including those with tap water exchanger. Normal mode (32 s) In normal mode the integration interval is set at 32 seconds, which means that the meter calculates accumulated volume and energy every 32 seconds. Normal mode is recommended for systems with hot water tank and similar systems in which changes are not taking place too quickly. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 44 ...

Fast mode is recommended for all systems including those with tap water exchanger. Mains mode (2 s) In mains mode, the integration interval is set at 2 seconds, which means that the meter calculates accumulated volume and energy every 2 seconds. Mains mode can only be used for mains‐supplied meters. Mains mode is available in two versions in which the backlit display turns off 15 s. after the latest activation of a key (L code = 4) or remains turned on (L code = 9) respectively. Mains mode is recommended for all systems including those with tap water exchanger. Mains mode is especially suitable for applications in which the meter is equipped with analog outputs.

If controlled output is required, the PP‐code is to be configured at 99. As previously described, the outputs are configured in pairs (C1/C2) and (D1/D2), which means that connected external equipment can switch the meters’ outputs, in the pairs C1/C2 and D1/D2, OFF (open opto‐transistor output) and ON (closed opto‐transistor output) respectively via KMP data commands. Output status can be read via the KMP‐registers and after a power‐on reset the outputs will have the same status as before the power failure as every change of status is saved in the meter’s EEPROM. 3.2.11 Data logger profile >RR<  MULTICAL 603 has a permanent memory (EEPROM), in which the results from various data loggers are saved. The data logger is programmable. The required data logger profile is selected via the RR‐code of the configuration number. Unless otherwise stated by the customer, the RR‐code is set to 10, which is a default data logger profile (equal to the data logger in MULTICAL® 602). If data logging of other registers, different intervals and logging depths are required, other data logging profiles can be composed to match individual requirements.

Page 57: Installation
MULTICAL® 603 Installation 4.1 Installation requirements Prior to installation of MULTICAL® 603 in connection with flow sensors, the heating system should be flushed while a fitting piece replaces the meter. If ULTRAFLOW® is mounted, the adhesive wafers are removed from the meter's inlet and outlet, and the flow sensor is mounted with couplings/flanges. New fibre gaskets in original quality must be used. If other couplings than the original ones from Kamstrup A/S are used, you must make sure that the threaded lengths of the couplings do not prevent proper tightening of the sealing surface. The positioning of the flow sensor in inlet or outlet can be configured in the calculator before commissioning, see paragraph 6.3 about SETUP loop. The flow direction is indicated by an arrow on the flow sensor. In order to avoid cavitation, the back pressure at ULTRAFLOW® (the pressure at the flow sensor outlet) must typically be minimum 1 bar at qp and minimum 2 bar at qs. This applies to temperatures up to approx. 80 C. When the installation has been completed, water flow can be turned on. The valve on the flow sensor's inlet side must be opened first. ULTRAFLOW® must not be exposed to lower pressure than the ambient pressure (vacuum). Permissible operating conditions Ambient temperature: 5…55C (indoors). Max 30 C for optimum battery lifetime.

Compact mounting Compact mounting means that the calculator is mounted directly on ULTRAFLOW®. If there is risk of condensation (e.g. in cooling applications), the calculator ought to be wall‐mounted. Furthermore, in cooling applications ULTRAFLOW® must be the condensation‐proof version. The construction of MULTICAL® 603 can provide minimum installation depth, using an angle fitting when mounting ULTRAFLOW®. Due to the design the mounting radius remains 75 mm in critical places. 4.2.2 Wall mounting The calculator can be mounted directly on an even wall. Wall mounting requires a wall fitting (3026‐ 207), which is available as an accessory to   MULTICAL 603. MULTICAL 603 is mounted on the wall fitting by sliding the calculator onto the fitting in the same way as it is done by compact mounting. 4.2.3 Position of calculator If the flow sensor is installed in humid or condensing environment, the calculator must be wall mounted and positioned higher than the flow sensor.

Installation sealing and SETUP loop In order to bring MULTICAL® 603 back to SETUP loop after installation, the calculator top and base must be separated, after which the SETUP loop can be accessed either via the front keys or METERTOOL HCW. Separation of calculator top and base implies that the calculator’s installation seal is broken. Verification seal The MULTICAL® 603 verification seals consist of both mechanical and electronic sealing. The verification seals marked “LOCK” and “TEST” are placed on the white verification cover in the calculator top. These seals can be seen as the ‘innermost’ sealing level, which may only be broken by authorized laboratories in connection with test and reverification of the meter. If the meter is to be used for legal operation in relation to approval and verification after breach of verification sealing, the broken seals must be resealed. The sealing must be carried out by an authorized laboratory using the sealing mark (void label) of the laboratory. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 60 ...

4 Tariff registers/tariff limits 9 saved 5 Measuring unit 10 The meter’s radio communication is switched on or off The meter uses four different display loops. The four loops are intended for four different usage situations.  USER loop The meter’s configurable display loop is intended for the user. The readings in this loop can be adjusted to the utility company’s requirements via the DDD‐code. See paragraph 3.2.4 for an overview of possible readings in the meter’s USER loop. The same paragraph includes examples of DDD‐codes.  TECH‐loop This loop is intended for technicians and is not configurable. The TECH loop contains all display readings, with the exception of logged values and the differential registers, and this loop is not configurable. The loop comprises readings such as serial number, date, time, config no., software revision and segment test. See paragraph 6.2 for a complete overview of the readings.  SETUP loop SETUP loop is intended for the technician too. In this loop the technician can configure the meter via the front keys. In general (unless otherwise informed by the customer), the loop is open in transport state. When the meter for the first time registers a flow of 1 % of qp or larger, the access to the SETUP loop is blocked. From now on it is no longer possible to access SETUP loop unless you break the installation seal. See paragraph 6.3 for further details about the various parameters which can be configured in the SETUP loop, and see paragraph 7.8 for details on the meter’s transport state.  TEST loop Used by authorized laboratories for reverification of the meter. This loop is not available unless the meter’s test seal (verification seal) is broken. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 63 ...
Page 64 MULTICAL® 603 By means of the meter’s front keys, you can choose from and switch between the four display loops. When delivered, the meter is in transport state, which means that the USER, TECH and SETUP loops are available. Depending on the country code, the access to the SETUP loop may be blocked in transport state, and the SETUP loop is thus not available on delivery. The TEST loop can only be accessed if the test seal (verification seal) is broken. By keeping the primary key activated for 5 seconds, you navigate to LOOP select. Here, you can use the arrow keys to switch between the meter’s display loops. In the TECH, SETUP and TEST loops, index numbers are used as the readings in these display loops are allocated to a specific index number. The index numbers facilitate navigation to the required reading. Index numbers are not used in the configurable USER loop. The below figure illustrates how it is possible to navigate in the meter’s display by means of the front keys. Readings in case of error In order to facilitate the diagnostics work, lines are shown in the display readings (current values) which are influenced by the error, and at the same time, counting stops in the registers, which are depending on the given parameter and thus influenced by the error. In case of interrupted or short‐circuited temperature sensor the corresponding display reading will include lines. MULTICAL® 603 registers these errors and sets an info code, which can easily be read from the display. Read more about info codes in paragraph 7.7.

When MULTICAL® 603 is connected to flow sensors with slow pulses, e.g. a reed switch, it will first indicate a decreasing current flow several minutes after the cut‐off. MULTICAL® 603 automatically sets the flow reading to 0 l/h after 60 minutes without pulses. For flow sensors with slow pulses, the flow reading will in general react slower and be less suitable for indicating low flows than when using flow sensors with fast pulses.

Page 74: Setup Loop
How to open the SETUP loop 1. In general (unless otherwise informed by the customer), the SETUP loop is available when the meter is in transport state. The meter leaves the transport state when the meter for the first time registers a flow of 1 % of qp or larger, or if the SETUP loop is ended via the menu item “EndSetup”. A total reset of the meter is the only way to return to transport state. 2. When the meter is in operation, i.e. the meter has left transport state, it is possible to access the SETUP loop by breaking the meter’s installation seal and separating the meter top from the meter base. How to exit the SETUP loop You can exit the SETUP loop in three ways. All three ways can be used both in transport state and after the meter has been put into operation. 1. Keep the primary key activated and navigate to the meter’s other loops. 2. After 4 minutes, the meter will reach time‐out and return to the first reading in the USER loop. 3. Navigate to the menu item “EndSetup” in the SETUP loop, and keep the primary key activated for 5 seconds, while the frames around the reading increments, and the display in the end shows “OK”. Note: This locks the access to the SETUP loop, and thereby the meter is locked against further configuration. Subsequent reconfiguration of the meter requires that you break the installation seal. IMPORTANT: “EndSetup” is an important function when the meter is in transport state, but when the meter is in operation, “EndSetup” is just one of three ways to exit the SETUP loop. As it appears from the table above, the purpose of the menu item “EndSetup” is to enable the technician to lock the access to the SETUP loop in transport state and thus lock the meter against further configuration. This function is e.g. relevant to a technician who knows that a meter is to be mounted in the installation for some time before the first integration is carried out and wants to lock the access to the SETUP loop immediately after the installation to ensure that no further configuration is possible.

Access to the SETUP loop loop blocked Timeout Access to the SETUP Access to the SETUP loop loop blocked EndSetup Access to the SETUP loop Access to the SETUP blocked loop blocked 6.3.1 Change of parameters in the SETUP loop You can navigate to the SETUP loop from the USER loop by activating the primary key for 5 seconds and then use the arrow keys to navigate to 3‐ SETUP that is accessed by pressing the primary key once. The SETUP loop does not include secondary readings, and therefore, the index number always consists of 4 digits. The arrow keys are used for switching between the readings. In the SETUP loop, the primary key is used for accessing individual readings with the purpose of changing the parameter in question. Pressing the primary key, the first digit of the parameter in question (the leftmost digit) starts flashing. The flashing digit can now be changed through brief activations of the primary key. Switch between the digits by pressing the arrow keys, move either to the right or to the left. When you have entered the required setup, activate the primary key until “OK” appears in the display. The meter has now saved the change and the display shows the set values. Depending on the meter’s configuration, one or more menu items in the SETUP loop will be displayed as “Off”. This means that the function is not available in the meter, i.e. the function has been disabled during factory programming. If you try to access these readings via the primary key, the frames around “Off” becomes illuminated to indicate that this function is not available in the meter.

The complete customer number can be adjusted via the two menu items in the SETUP loop. 3. Date The meter’s date can be adjusted in the SETUP loop. It is recommended to verify that the date was adjusted correctly, especially if time was adjusted too. 4. Time The meter’s time can be adjusted in the SETUP loop. It is recommended to verify that the time was adjusted correctly, especially if the date was adjusted too. 5. Yearly target date 1 The meter’s yearly target date 1 can be adjusted in the SETUP loop. In MULTICAL® 603, it is possible to activate yearly target date 2. This function is switched off by default, i.e. set at 00.00. If yearly target date 2 is active in a meter we recommend that both yearly target dates are adjusted via METERTOOL HCW to ensure that they are correctly set with respect to each other. Note that the activation of yearly target date 2 influences the depth of the yearly log as the meter now makes two yearly loggings. 6. Monthly target date 1 The meter’s yearly target date 1 can be adjusted in the SETUP loop. In MULTICAL® 603, it is possible to activate monthly target date 2. This function is switched off by default, i.e. set at 00. If monthly target date 2 is active in a meter we recommend that both monthly target dates are adjusted via METERTOOL HCW to ensure that they are correctly set with respect to each other. Note that the activation of monthly target date 2 influences the depth of the monthly log as the meter now makes two monthly loggings.

Page 78 The installation position of the flow sensor can be adjusted in the SETUP loop. This means that the meter can be changed from being an outlet meter to being an inlet meter and vice versa. A symbol in the top left corner of the meter’s display shows whether the meter is configured as an inlet or an outlet meter. 8. Energy unit (B‐code) The meter’s measuring unit (B‐code) can be adjusted in the SETUP loop. It is thus possible to select if the meter’s energy readings are to be shown in kWh, MWh, GJ or Gcal. Note: The resolution of the energy unit always follows the one stated for the CCC‐code with which a given MULTICAL® 603 is configured, see the CCC‐tables in paragraph 3.2.3. Note that MULTICAL® 603 automatically switches to MWh if kWh is selected for MULTICAL® 603 with a CCC‐code where kWh is not possible. 9. Primary address of internal M‐Bus It is possible to set the primary address of the internal M‐Bus in MULTICAL® 603 in the SETUP loop. The address can be selected in the interval 0…250. 10. Primary address of module slot 1 It is possible to set the primary address of module slot 1 in MULTICAL® 603 in the SETUP loop. The address can be selected in the interval 0…250. 11. Primary address of module slot 2 It is possible to set the primary address of module slot 2 in MULTICAL® 603 in the SETUP loop. The address can be selected in the interval 0…250.

Page 79 13. Heat/cooling shift ( ) The limit for heat/cooling shift ( ) can be adjusted in the SETUP loop, however only in meters ordered as meter type 6 (heat/cooling meter). The value can be selected in the interval 2…180.00 C as well as at 250.00 C if the user wants to disable the function. The function is enabled again by setting the limit at a value in the valid area of 2…180 C. Heat/cooling shift is permanently disabled on other meter types, and the display thus shows “Off” on all other meter types than 6. Read more about heat/cooling shift in paragraph 7.4. Meter type: 1, 2, 3, 4, 5, 7 Meter type: 6 The frames around “Off” illuminates as The first digit flashes and each digit can long as the primary key remains now be set at a value within the range activated. 0…9. If you choose a value outside the valid interval (2…180.00 C), the value is automatically adjusted to 250.00 C, which indicates that the function has been switched off. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 79 ...
Page 80 Offset can be adjusted in the interval ‐0.99…0.99 K. By pressing the primary key, the 0 and the sign start flashing, and it is now possible to toggle between – and +, indicated in the display by the fact that the minus sign flashes and switches off respectively. By pressing the arrow keys, the meter shifts focus to the first decimal, i.e. it is not possible to change the value of the first digit as the valid interval is ‐0.99…0.99 K. Both the first and second decimal can be set to a value between 0 and 9. Read more about order data in paragraph 7.3. Be aware of setting the required offset adjustment, not the error of the temperature sensor pair. If the selected temperature sensor pair contributes with an error of ‐0.20 K, the meter’s offset must be set at 0.20 K. Note: The set offset is active for all temperature sensors that are connected to MULTICAL® 603, i.e. both t1, t2 and t3. 15. Radio on/off The meter’s radio/wireless communication can be adjusted to being switched on or switched off. The meter automatically turns on the radio when the meter leaves the transport state, i.e. when the meter has registered a flow of 1 % of q or larger. The radio on/off function in the SETUP loop is primarily used for switching on the radio in transport state, without the meter having registered flow, as well as for switching off the radio when the meter is dismounted after having been in operation, e.g. If the meter is to be sent by airfreight. The meter’s present condition is indicated by two symbols in the bottom left corner of the display. IMPORTANT: ‐ If the meter's radio communication is switched off via the SETUP loop, the meter will subsequently switch on the radio communication again when a flow of 1 % of qp or larger has been registered for the first time. ‐ The symbols for radio on/off indicate whether the meter allows radio communication, not whether a radio module has activated its radio communication. Please be aware of this when troubleshooting the meter’s wireless communication. The above definition of the radio on/off symbols simplify the use of radio on/off in the SETUP loop too as it is possible to switch between radio on/off whether a module is mounted in the meter or not. This provides flexibility as the utility can configure the meter prior to mounting a module and thus ensure that radio by default is either switched on or switched off when the module is subsequently mounted.

Page 81 It is possible to pre‐set the values of pulse inputs A1 and B1 in the SETUP loop so that the meter’s display is in accordance with the connected water and/or electricity meters. The example is based on the connection of a water meter. Note: If it is required to use the pulse inputs A2 and B2, METERTOOL HCW is used for pre‐setting the registers. 18. + 19. Meter numbers of inputs A1 and B1 The meter numbers of the water and/or electricity meter connected to pulse inputs A1 and B1 can be adjusted in the SETUP loop. The example shows the meter number connected to pulse input B1. Note: If it is required to use the pulse inputs A2 and B2, METERTOOL HCW is used for setting the meter numbers. 20. + 21. + 22. Tariff limits (TL2, TL3 and TL4) The meter’s three tariff limits can be adjusted in the SETUP loop. The tariff limits are only active if a tariff type has been selected during configuration of the meter, i.e. the EE‐code differs from “00”. The EE‐code is shown in the TECH loop, see paragraph 6.2. If a tariff type has been selected, the menu points reflect this by displaying the correct tariff limit units. If no tariff type has been selected the menu points will be without units. Read more about tariff types in paragraph 3.2.5. Note: It is not possible to have different types of tariff limits. The display readings shown are just examples.

Page 82 A1 (A‐, heat at a discount) and A2 (A+, heat with an addition). Read more about this calculation and function in paragraph 7.1.3. 24. EndSetup The menu item “EndSetup” enables the technician to lock the access to the SETUP loop in transport state and thus lock the meter against further configuration. To do so, the user must keep the primary key activated for 5 seconds. During the five seconds the frames around the reading EndSetup will currently become illuminated in the meter’s display. This action can be undone by releasing the primary key before the whole frame has become illuminated, i.e. before the 5 seconds have passed. “EndSetup” is an important function when the meter is in transport state, but when the meter is in operation, “EndSetup” is just one of three ways to exit the SETUP loop.

Page 83: Test Loop
MULTICAL® 603 6.4 TEST loop The TEST loop is e.g. used by authorized laboratories for reverification of the meter. Before the meter can enter the TEST loop and thus the TEST mode, the verification seal marked “TEST” on the meter’s verification cover must be carefully broken with a screwdriver and the contact points behind the seal be short‐ circuited. For this purpose, the short‐circuit pen (6699‐278) from Kamstrup A/S can be used. It is recommended to complete the work in the TEST loop before starting the reconfiguration via the SETUP loop or METERTOOL as every reconfiguration is logged in MULTICAL® 603 (it is only possible to reconfigure MULTICAL® 603 50 times). The meter leaves the TEST mode and returns to the first reading in the USER loop after 9 hours (time‐out), or if the user keeps the primary key activated for 5 seconds.

Current CP is set to 0.0 until the daily log has logged over the configured number of days (if number of days, for example, is set to 5, the meter cannot make a calculation over 5 days until it has carried out 6). 7.2.2 Seasonal Coefficient of Performance (SCOP) SCOP is an average measurement of the heat pump’s coefficient of performance, which indicates how efficient it is on a yearly basis. The average yearly value is measured over a year (one season) in which the heat pump has experienced both high and low ambient temperatures. By selecting logger profile (RR‐code), it is possible to save both yearly and monthly values. The monthly values are calculated as the average of a full month, and the yearly values are calculated as the average of a full year. Month and year are determined by the selected target date. 7.2.3 Measurement of the coefficient of performance (CP) of a gas boiler If the pulse output of a gas meter is connected to a heat meter, the coefficient of performance of the gas boiler can be measured, in terms of e.g. kWh/Nm gas. A volume resolution which corresponds to the pulse weighting on the gas meter pulse output must then be selected for input B1. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 98 ...
Page 99: Offset Adjustment Of Temperature Sensor Measurement
MULTICAL® 603 7.3 Offset adjustment of temperature sensor measurement MULTICAL® 603 is available with possible offset adjustment of the temperature sensor measurement, thus increasing the accuracy of the absolute temperature measurement. This is especially relevant in the installation scenario that the meter is to be used for tariff billing based on absolute temperatures. In that case, it is an EN1434 requirement that the accuracy of the meter’s absolute temperature reading must be within ± 1.0 K. Offset adjustment is extremely relevant in district cooling installations too. In district cooling installations the customer often requires a maximum inlet temperature. Absolute temperature measurement measuring with undesirable inaccuracy can cause the supplier to supply water with a lower inlet temperature than promised, resulting in unnecessary extra costs for the supplier. Depending on the meter’s configuration, the offset adjustment can be programmed into the meter from the factory. In addition, offset can be adjusted after delivery via the meter’s SETUP loop (see paragraph 6.3) or via METERTOOL HCW (see Technical description 5512‐2096). Note: Depending on the meter’s configuration, the offset adjustment can be disabled, and in this case, the menu item in the SETUP loop will display “Off”. If the temperature sensor pair of a meter with offset adjustment is replaced, it is recommended to correct the offset to match the newly connected sensor pair. Alternatively, offset should be adjusted to 0.00 K, which means that the function is switched off and does not contribute to an undesirable increase of the error of the absolute temperature measurements. Note that the offset adjustment influences connected temperature sensors on both t1, t2 and t3. Temperature sensor offset (t ) can be adjusted in the interval ‐0.99…0.99 K according to the meter’s approval. Please be aware that the required offset adjustment must be entered, not the error of the temperature sensor pair. If the selected temperature sensor pair contributes with an error of ‐0.20 K, the meter’s offset must be set at 0.20 K. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 99 ...
Page 100: Combined Heat/Cooling Metering
Country code (language on label etc.) XX If MULTICAL® 603 has been supplied as a heat/cooling meter (meter type 3 and 6), heat energy (E1) is measured at a positive temperature difference (t1>t2) whereas cooling energy (E3) is measured at a negative temperature difference (t1<t2). Temperature sensor t1 (marked in red) is mounted in the inlet, whereas t2 (marked in blue) is mounted in the outlet. θ functions as a limit value for cooling energy measurement. This means that cooling energy is only measured when the inlet temperature t1 is lower than θ . In heat/cooling meters, the limit value θhc should be set at the highest temperature which has appeared in the inlet in connection with cooling, e.g. 25 °C. If the meter is to be used for billing, the functionality θhc is disabled. Thereby, the differential temperature alone decides whether cooling or heat energy is invoiced. Configuration of the function θ is only possible in meter type 6. Configuration is possible in the interval 0.01..180.00 °C. In order to disable θ , it must be configured at 250.00 °C. In other meters than meter type 6, θ is permanently hc “Off” in the configuration. θ is configured via the SETUP loop or by means of the PC‐program METERTOOL HCW, see hc paragraph 6.3 and 14 for more details. Note: There is no hysteresis in connection with shift between heat and cooling energy measurement (Δθ = 0.00 K). Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 100 ...

All calculated flow and power values from the averaging period are used in the calculation of the average. Calculated values are compared to previous values, and the new value is saved if it exceeds the previous maximum value or is lower than the previous minimum value. The averaging period used in all calculations can be selected in the interval 1...1440 minutes in leaps of 1 minute (1440 min. = 24 hours). The averaging period and the target dates are stated in the order. Read more about order data in paragraph 3.3. If not otherwise stated in the order, the default averaging period of 60 minutes is used. This value can later be changed via the SETUP loop or METERTOOL HCW. Please note the following:  In the display the date is shown in the format 20YY.MM.DD, but by serial reading the time can be stated too, and the format then becomes YY.MM.DD, hh.mm.ss.  The average is calculated continuously over time, i.e. the average of values is calculated from now on and back in time according to the chosen averaging period. As a result, the min/max calculation is immune to the clock setting and will always move continuously through time. Kamstrup A/S ∙ Technical description ∙ 5512‐2029_A1_GB_06.2017 102 ...

7.13 Differential energy and volume calculation MULTICAL® 603 has integrated differential calculation of energy and volume. The result of these calculations are saved in the following four registers: dE: difference Energy (E4 ‐ E5 > 0) cE: control Energy (E4 ‐ E5 < 0) dV: difference Volume (V1 ‐ V2 > 0) cV: control Volume (V1 ‐ V2 < 0) All four registers are accumulated registers where dE and dV count at a positive difference and cE and cV count at a negative difference. A reading of both the difference and the control registers reveals how much registers have been counted with a positive or negative difference over a given period, thus it is possible to get information about how stable the system has been throughout the selected period. The calculations follow the selected integration mode, and the calculations are thus carried out at the selected integration interval. All four registers can be displayed in the meter's USER loop and are saved in the meter’s loggers. See paragraph 3.2.4 about display setup (DDD‐codes) and paragraph 3.2.10 about possible logger profiles (RR‐codes).

Page 120: Temperature Sensors
On MULTICAL® 603, Pt100 and Pt500 temperature sensors can be used for which the nominal resistance at 0 °C is 100 Ω and 500 Ω, respectively. The correlation between the resistance R and the temperature t is defined as: where R indicates the resistance at 0.00 °C, whereas A and B are constants. The values R , A and B are determined at the verification of temperature sensor, which is carried out according to EN1434‐5. On a heat or cooling meter, a temperature sensor set is used for measuring the temperature difference between inlet and outlet. As each of the two temperature sensors has its own values for R , A and B, the requirement for an approved temperature sensor is, according to EN1434‐1, that the maximum allowed difference in percent between the two temperature sensors, E , in the entire approval area is: ∆ ∆ where Δθ is the concrete temperature difference and Δθ is the minimum allowed temperature difference, typically 3 K. The values R , A and B, of the separate temperature sensors as well as E appear from the certificate of the temperature sensor set. 9.1 Cable influence and connection of cables Mostly, only relatively short cable lengths for temperature sensors are needed for small and medium‐size heat meters, which means that 2‐wire sensor sets can be used with advantage. 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.

MULTICAL® 603 12 Data communication  12.1 MULTICAL 603 data protocol  Internal data communication in MULTICAL 603 is based on the Kamstrup Meter Protocol (KMP) which provides a fast and flexible reading structure and also fulfils future requirements to data reliability. The KMP protocol is used in all Kamstrup consumption meters launched from 2006 onwards. The protocol is used for the optical reading head and via plug pins for the module area. Thus, modules with e.g. M‐Bus interface use the KMP protocol internally and the M‐Bus protocol externally. 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. 12.2 Optical readout head The optical reading head can be used for data communication via the optical interface. The optical readout head is placed on the front of the calculator just above the IR‐diode as shown in the figure below. Note that the optical readout head includes a very strong magnet, which should be protected by means of an iron disc when not in use. Various variants of the optical readout head appear from the list of accessories (see paragraph 3.1.1). Power‐saving in connection with the optical readout head In order to limit the power consumption of the circuit around the IR‐diode, the meter includes a magnet sensor which switches off the circuit when there is no magnet close to it. 12.3 Data protocol Utilities and other relevant companies who want to develop their own communication drivers for the KMP protocol can order a demonstration program in C# (.net‐based) as well as a detailed protocol description (in English language).
