Accessories BUS communication The energy calculator needs a special adapter cable to communicate with a PC for signal compatibility with the RS 232 level. To access the terminals, it is necessary to use one of the supplementary modules pulse output or input module, which, in addition to specific terminals - both have 3 terminals for connection to a PC. Pulse output module Module contains 3 terminals for DATA, REQUEST and GND. There are also 2 x 2 terminals for CE, CV/Alarm. Both outputs are galvanically separate. Pulse sequence CE: 1 pulse per change in the least significant digit in the energy unit and resolution selected. Pulse sequence CV: 1 pulse per change in the least significant digit in the volume unit and resolution selected. Alarm: 1 pulse per hour for as long as the unit has detected a fault. The function is not activated in the standard configuration. M-bus module The M-bus protocol is in accordance with EN 1434-3 and EN 60870-5. For communication with an M-bus, it is necessary to fit energy calculator with an add-on module. The M-bus module contains, in addition to terminals for BUS connection, terminals for counter inputs A and B. DH-SMT/PL VD.SH.A1.02 Danfoss 06/2006 3

Thanks to application of this innovative principle of operation the measures are characterized by accuracy and reliability, and in connection with wide range of dynamic measures those flow meters have assurance of more than 20 years operation stability. The ultrasonic principle is used in measuring the flow. Two ultrasonic transducers functioning as both transmitter and receiver are positioned opposite each other at the inlet and outlet of the flow meter. Ultrasonic signals are transmitted between both transducers. One signal travels in the same direction as the water flow, the other travels against the flow. District heating systems with ultrasonic flow meter Measurement is performed by determining the time the ultrasonic signal takes to travel with and against the flow. The principle can be expressed as follows: t up t down Δt v = K = K t up x t down t 2 t down = Time in the flow direction t up = Time against the flow direction v = Average flow velocity t = Transit time K = Proportional factor This measuring principle offers the advantage that it is independent of variations in the actual sound velocity of the liquid. Proportional factor K is determined by wet calibration. 6 VD.SH.A1.02 Danfoss 06/2006 DH-SMT/PL

Calculation Calculation of energy is based on the following formula: Energy = Volume x (T Hot - T Cold ) x K factor (T i ) Volume: T Hot : T Cold : K factor (T i ): Volume [m 3 ] of a given amount of water Measured temperature in the flow Measured temperature in the return Thermal coefficient of water based on the polynomial associated with Dr. Stuck s tables of enthalpy and heat content The energy calculation is made by a counter that depends on the size of the flow meter, pulse frequency and legal requirements. The calculator always carries out at least one energy calculation every 10 minutes if the flow meter has not sent enough pulses to prompt an energy calculation. Temperature measurement The energy calculator has been developed for paired Pt 500. For each energy calculation, a temperature measurement is taken according to a dual-slope measuring principle, and a measurement of two reference resistances. This compensates for temperature and long-term drift, and any effect of supply frequency (hum) on the temperature measurements is compensated for. Contact resistance between the top and bottom parts is compensated for by a three-conductor measurement. Permanent memory/account date reading The LOG of the calculator is updated every 10 minutes with all the cumulative values: - Date, - S energy, - S water, - S records 1 and 2, - peak values of energy or flow, - counter records A and B, - date/time and info code. The energy calculator allows for two possible account date outputs. If the use of account date output has been selected during configuration, the above data are stored to enable output to a selected date in the year. All data are stored for a further 24 months in a record for possible subsequent study of operating conditions in the system. Tariff record In addition to the main record, 2 extra records can be used: tariff records 1 and 2. There are two tariff limit values associated with each of the two records, which can be reprogrammed using Danfoss energy calculator reprogramming software. The following tariff types are available: - Power-based tariff, flow-based tariff, cooling tariff, return temperature tariff, flow-controlled tariff with summation of time. - The tariff record is set to flow-controlled tariff as standard, and qs is set as limit (depending of flow type). - Tariff records are not available whenever choosing an energy calculator for combined cooling/heating. Energy/volume maximum Energy and volume can be outputted for the previous three months with associated dates when the maximum power occurred. Integration time can be set to 15, 30 or 60 minutes. Standard factory setting: peak volume: 15 minutes; peak energy: 60 minutes. Views are NOT active in the standard display configuration. Error handling If energy calculator records an error, this will be indicated by a and a! in the display for a sensor error or for another error. The error will similarly be recorded on the LOG. The LOG can contain up to 10 failures with a statement of date/time of occurrence of the error and eventually occurrence of the error. Using the function key, it is possible to read the error code, which is indicated by an F. Resetting the error code is undertaken either using a hand terminal or by briefly separating the calculator top from the lower part and re-connecting it with the lower part, while the operating button is held down. The energy calculator is now in a reset mode, and error codes can be deleted from the display. The following errors can be detected: F1 Forward temperature sensor is interrupted or short-circuited. F2 Return temperature sensor is interrupted or short-circuited. F3 Internal equipment error. F4 Differential temperature high and no flow for 48 hours. F5 Water flow exceeds preset Qs. Accounting date output The accounting date is set as standard to June 1. Secondary accounting date is inactive. This function with associated display menu settings is activated in the build-up number under identification key MM. 10 VD.SH.A1.02 Danfoss 06/2006 DH-SMT/PL

Zero point calibration of differential temperature (only types CF/CR) Cooling systems always operate with a small Δt and a relatively high flow rate. For technical reasons no sensor pair provides completely accurate temperature difference measurements when the sensor temperature difference between forward and return flow is close to zero. The energy calculator type CF/CR contains a special zero point calibration routine that can be activated in order to minimize the temperature difference measuring failure. Normally the zero point calibration is not needed, but can be activated out in order to obtain maximum accuracy in the energy calculation. The zero point calibration function requires a short circuit between forward and return sensor in the cooling system e.g. by installing a valve V1. (See application drawing). Optical output The energy calculator is fitted with an optical infra-red send/receive port in accordance with IEC 61107. Protocol standard, EN 60870-3 (M-bus protocol). A reader head with a permanent magnet in accordance with EN 1434 can be used for programming/altering programming of readout data, configuration data, etc. The reader head can also be used for amendment of measuring data. Temperature sensors The temperature sensor set is designed for use with the energy calculator for measurement of the energy consumption in a district heating net. To ensure an accurate measurement of the temperature difference according to EN 1434, the sensors are delivered as matched pairs. The sensor set can be supplied with type approval marking according to local demands. Mounting Flow meter, type SONO 2500 CT The flow meter can be mounted in either forward or return pipes. The correct direction is indicated with an arrow on the flange or on the body. When horizontally mounted, the max. liquid temperature is 150 C. For 3.5 m 3 /h max. 130 C. The max. liquid temperature must be reduced to 120 C when the electronics (black enclosure) is turned upwards. When vertically mounted, the max. liquid temperature is also 120 C. The electronics (black enclosure) must not be insulated. The length before the flow meter must at least be 5 x DN. The flow meter must be filled completely with water during measurements. It is not necessary to use filters when using the flow meter. DH-SMT/PL VD.SH.A1.02 Danfoss 06/2006 11
