We will be glad if the above information was useful to you, and we also thank you in advance for contacting any of the representative offices of the Teplopribor group of companies (three Teplopribor, Teplokontrol, Prompribor and other enterprises) and promise to make every effort to justify your trust.
To dispatch heat meters Logic SPT941, SPT943, you must first configure the communication parameters.
Press the MENU key and hold for about 2 seconds. The main menu of the heat meter will be displayed on the screen (using the example of SPT943.2), the cursor is placed under the GEN section:
Press the ↓ key to enter the General section of the menu, and then the -> key to move the cursor under the DB (database) section.
Press the ↓ key to enter the database, after which the screen will display the first of the section parameters and its value (EI=0):
Press the ↓ key several times until the NT option appears on the screen ( network address device).
If the facility uses one heat meter and it is not connected via a network with other Logic meters, we recommend setting the parameter value equal to one. (To change a parameter, press the ENTER key, then press the key to set the desired value, and press ENTER again to save.)
Now use the ↓ key to go to the next section parameter, CI (data interface configuration):
The value CI =0 is set by default and indicates connection communication equipment to the computer at a speed of 2400 bps. If you use a GSM modem to transfer data from the computer, we recommend setting this value and setting up the equipment and software on the dispatcher’s computer side accordingly. Firstly, it significantly saves the battery life of the computer. Secondly, in the case of unstable GSM communications, and the absence of external requests special form within 10 seconds, the computer will automatically set the parameter value equal to zero(2400 bps).
The setup of the heat meter is now complete (if you are using SPT941, the setup will be identical, with the only difference being that in the main menu of the device you first need to select the SETUP section, and then the DB section). Let's move on to connecting to the dispatch system. We recommend using (Fargo Maestro 100 or iRZ Q24) as a data transfer device.
A “smart” GSM modem does not require receiving staticIP addresses from the mobile operator, excludesfreezingGSM channel and module. Afterpower supplymodem automaticallywill come outto the network, will provide a transparent data transmission channel with a meter,and will becontrolconnection quality, rebooting if necessary.
Let's prepare a “smart” GSM modem for working with SPT941/943. Using, run the MtCfg utility from NPO Teplovizor and carry out necessary actions. After specifying all required parameters connection to the dispatch system, configure the modem port to connect to SPT941/943.
To do this, select the menu item Modem->UART Settings…
set the following values:
and press the button Save settings. Don't forget to check the box next to " Save settings in non-volatile memory«.
Now all devices are ready for operation, you need to perform physical connection. Unfasten the cover of the device to gain access to the terminals:
The RS-232 communication port we are interested in is located on connector X2:
Connect the MT9 modem and the heat meter in accordance with this diagram (the colors of the connecting lines in the diagram are arbitrary and do not match the colors of the conductors in the modem cable):
Sometimes it may be necessary direct connection laptop to the heat meter (service tasks, changing the device configuration, local data acquisition, etc. on-site work).

Consumption scheme number (0...99). The scheme is selected based on section 4 of this manual. This parameter must be set before assigning other input parameters, since the range of database parameters depends on the selected scheme. If the SP change was made while counting was running, then the parameters V, M, Q, Ti accumulated since the beginning of the current hour will be reset to zero. If you need to save the accumulated data, you should stop the counting, wait until the end of the hour, then change the scheme number and start the counting again.
Countdown time. Serves to set the internal clock of the heat meter. It is specified in the hours–minutes–seconds format. The range for setting hours is from 00 to 23, minutes – from 00 to 59, seconds – from 00 to 59. Changing the counting time, as well as the counting date, leads to a change in the natural order of maintaining archives.
Reference date. Serves to set the heat meter calendar. Specified in the format day–month–year; the range for setting the day is from 01 to 31, the month is from 01 to 12, the year is from 00 to 99. Changing this parameter entails changing the natural order of maintaining archives.
Settlement days. Define the end date of monthly archiving intervals. Set in the range from 01 to 28 days.

C1, C2, C3 Volume sensor pulse price (0.000000…9.999999 m3). The value of the BC pulse is set according to the data sheet for the volume sensor. If the passport indicates the actual price of the impulse, which differs from the nominal price, then choose the actual price, thereby minimizing the measurement error. Gв1, Gв2, Gв3 The upper limit of the flow measurement range of the corresponding volume sensor (0... 99999.99 m3/h). If the current flow rate exceeds the upper limit value, then an abnormal situation is recorded, and when KG = 1, it is not the actual flow rate that is involved in the calculations, but the flow constant. Set according to the data sheet for the volume sensor. Gn1, Gn2, Gn3 The lower limit of the flow measurement range of the corresponding volume sensor (0...99999.99 m3/h). Replaces the measured flow value at 0 Gk1, Gk2, Gk3 Flow constant for pipelines 1, 2 and 3 (0...9999.99 m3/h). In the case of assigning KG=1 or KG=3, replaces the measured flow value through the corresponding volume sensor at G>Gв, and in the case of assigning KG=2 or KG=3, the constants Gк1, Gк2 and Gк3 replace the measured flow value through the corresponding sensors, if available HC02. tk1, tk2, tk3 Temperature constant for pipelines 1, 2 and 3 (0…175 ºС). Replaces the measured temperature value of the corresponding sensor when this value goes beyond the limits of 0-176 ºС or in the absence of a sensor.

When calculating using the constants tхк=0 and Pхк=0, the enthalpy of cold water is assumed to be zero. Algorithm for using Mk. Defines the conditions for using the constant Mk instead of the difference in hourly masses (M1h–M2h), for schemes 0, 1 and 10 when calculating the hourly value of thermal energy and mass. The parameter can take the following values: 0 – Mk is not used; 1 – (M1h–M2h)=Mk at (–NM)M1h≤(M1h–M2h)<0; 2 – (M1h–M2h)=Mk at (M1h–M2h)< 0; 3 – (M1h–M2h)=Mk at (–NM)M1h≤(M1h–M2h)<0 и (M1h–M2h)= ρ3V3h at (M1h–M2h)< (–НМ)М1ч; 4 – (M1h–M2h)= ρ3V3h at (M1h–M2h)< 0 Unless otherwise specified in the agreement with the energy supply organization, the AM parameter is set equal to zero. Hourly mass constant (0...99999.99 t/h). When calculating thermal energy (at an interval of one hour) for schemes 0, 1 and 10, it replaces the calculated value (M1h–M2h), in accordance with the algorithm specified by the AM parameter. Unless otherwise specified in the agreement with the energy supply organization, the parameter Mk is set equal to zero. Setting for mass imbalance (0.0000...0.0400). Determines the limit value of the maximum mass imbalance, when exceeded, i.e. at (M1h–M2h)<(–НМ)М1ч, происходит активизация НС16 (подробнее см. в гл. 7). Determined taking into account the accuracy class of the flow meters used in the heat meter. For example, for flow meters with a relative error of 2%, it is possible to set the NM value equal to (2+2)/100=0.04. The parameter is set only for circuits 0, 1 and 10 with AM≠0. Calculation algorithm using Qк (0; 1; 2; 3; 10; 11; 12; 13). Parameter 1 determines the conditions for using the constant Qк instead of the calculated value of thermal energy at the hourly interval Qh. 0 – Qк is not used; The actual measured and calculated value is always added to the archive and to the total heat meter; 1 – Qк is used with a negative Qch value, and HC17 is activated; 2 – the same as with AQ=1 and/or when the difference in hourly masses M1h–M2h (for schemes 0, 1 and 10) goes beyond the permissible range determined by the NM parameter (when NS16 is activated); 3 – the same as with AQ=2 and/or when the parameter values from any of the primary temperature converters go beyond the permissible limits (i.e. when an emergency situation NS08 or NS09 is activated). It does not matter how long the parameter was out of range; 10 – Qk is used for the time while HC04 is active; 11 – Qк is used for the time while HC04 is active and with a negative Qch value; 12 – the same as with AQ=11, and/or when the difference in hourly masses M1h–M2h (for schemes 0, 1 and 10) goes beyond the permissible range determined by the NM parameter (when HC16 is activated); 13 – the same as with AQ=12, and/or when the parameter values from any of the primary temperature converters go beyond the permissible limits (i.e. when an emergency situation NS08 or NS09 is activated). Hourly heat constant (0...9999.99) [Gcal, GJ, MWh]. Changing clocks to winter and summer time. When assigning PL=0, the clock is not changed. If PL = 1, the clock will be automatically moved back an hour at 3 am on the last Sunday in October and forward an hour at 2 am on the last Sunday in March. Signal monitoring at a discrete input. (0; 1; 2). 0 – control disabled; 1 – activation of HC02 in the presence of a signal; 2 – activation of HC02 in the absence of a signal. Network number (0…99). Used in requests from a computer or APS45 printer adapter. When several heat meters are connected in parallel, their network numbers must be different, otherwise the devices cannot be clearly identified. When operating a single device with any of the listed types of equipment, the network number does not need to be specified. Identifier (0...99999999) Serves to organize information received from a large number of metering devices in centralized data collection and processing systems. The identifier is usually set equal to the serial number of the device. Interface configuration (0;1;2;10;11;12). 0 – connection of the APS45 adapter, computer or other equipment at a speed of 2400 bps; 1 – connection to a telephone modem or GSM modem operating using CSD technology (9600 bps); 2 – connection to a telephone modem or GSM modem operating using CSD technology (19200 bps); 10 – connection of a GSM modem to work using GPRS technology with a fixed IP address (2400 bps); 11 – connection of a GSM modem to work using GPRS technology with a fixed IP address (9600 bps); 12 – connection of a GSM modem to work using GPRS technology with a fixed IP address (19200 bps). The value of this parameter does not affect data exchange with external equipment via the optical port. In the absence of external equipment, it is recommended to set the value KI=0. This purpose will increase the battery life. The beginning of the allowed modem operating time interval. Set in hours-minutes format (00-00…23-59). The end of the allowed modem operating time interval. Set in hours-minutes format (00-00…23-59). Another option for using the VMN and VMC parameters is to control the number of calls before auto-answering. To do this, set VMN=VMK; the number of calls before auto answer will be equal to the number of minutes in the parameter value. When the number of minutes is less than three, auto answer is scheduled for the second call. In this case, the value of the first two digits of this parameter can be arbitrary. Changes related to setting the number of calls before auto-answering take effect no later than 30 minutes from the moment you enter the values of the VMN and VMC parameters. If you want these changes to take effect immediately, you should run a standard modem function test (SETUP-TST-MODEM-STD). Print daily reports (1; 0). Enable/disable automatic printing of daily thermal input reports. When PS = 1, every day, at checkout time, archived data for the past day is put into the print queue. Jobs in the queue will be printed upon request from the APS45 printer adapter. The settings of this parameter do not determine the conditions for outputting reports to the computer and reading device. Print monthly reports (1; 0). Enable/disable automatic printing of monthly thermal input reports. The settings of this parameter set the mode for automatic output of monthly reports to the printer, similar to the settings of the PS parameter. Password for remote access. Specified by the user as a sequence of numbers and letters of the Latin alphabet. The maximum number of characters in the password is 8. To effectively protect your data, you should choose passwords that are as long as possible. To disable data protection using a password, set the value PW=0. Password protection does not apply when accessed via the optical port. Password protection does not work when assigning CI=0. Monitoring the value of one of the current parameters for the condition of going beyond the range specified by the UN…UV settings. The parameter can take the following values: 0 – control disabled; 1 – control enabled; When the control is turned on and the parameter goes beyond the boundaries of the range UN...HC, HC04 is activated. The number of the parameter whose value is monitored for compliance with the settings. Can take a value from 0 to 5, corresponding to the following parameters: The current parameter, the value of which is controlled by the settings, is marked in the TEK section with the symbol “bell;”. Upper setting. (-999999.9…999999.9). The upper limit of the range to which one of the current parameters is monitored. Low setting. (-999999.9…999999.9). The lower limit of the range to which one of the current parameters is monitored. Setup data lists are always available for viewing. Any parameter can be displayed on the display by scrolling through the list using the ↓ and . Entering and changing setting data is carried out in the so-called non-protected mode, when the data protection switch is in the down position. When it is installed in the upper position, any data changes are blocked, and a stylized image of a lock appears on the display. However, if, due to operating conditions, it is necessary to change the values of any parameters without unsealing the device, then this can be provided for when describing them in the database. Such parameters are marked with the symbol “” and are called operational. Data entry begins and ends by pressing the ENTER key, and is carried out using the ← and → keys (selection of familiarity), ↓ and (selection of numbers from 0 to 9 and the symbols "," and "–"). To set (remove) the sign of an operational parameter, you must press the ENTER key, after first pressing and holding the ← key. Figure 5.6 illustrates the sequence of actions when entering data. The parameter values are given as an example. Figure 5.6 – Entering the numerical value of the parameter CP=25 5.3.2 TCT-CIRCUIT mode (TCT-CIRCUIT SETUP) X4, X5, X6 Input signal value [Hz] at the corresponding connector Measured in the range from 0.0008 to 1000 Hz s relative error no more than 0.01%. X7, X8 Input signal value [Ohm] at the corresponding connector Measured in the range of 100-160 Ohms with absolute no more than 0.04 Ohm error. 5.3.3 TST-MODEM mode (SETUP-TST-MODEM) This item contains a number of service functions for working with telephone and GSM modems Test of standard modem functions (SETUP-TST-MODEM-STD) The test allows you to judge whether the modem is connected and configured (initialized) correctly. The test works with both telephone and GSM modems. If the modem is configured and connected to the device correctly (according to the recommendations published on the website www.logika.spb.ru), the result of the test should be the message Rx: OK displayed on the device display (Fig. 5.7). The number "2" in the first line corresponds to the number of calls before automatic answering and is given as an example. Figure 5.7 – Image on the scoreboard when the test is successfully completed If errors occur or there are no modem responses, the message Rx: Error or Rx: No response will be displayed on the display. Information about the GSM modem (SETUP - TST-MODEM-GSM) Scrolling through the information on the display is carried out using the and ↓ keys. An example of the information displayed is shown in Figure 5.8. Figure 5.8 – Information displayed on the display in the mode SETUP-TST-MODEM-GSM. The IP address of the GSM modem is displayed if the data is transferred using GPRS technology, which should be reflected in the modem settings and the heat meter configuration database (CI parameter). Request account status (SETUP-TST-MODEM-SCH) In this mode, a request for a report on the current state of the subscriber's cash balance is sent to the cellular operator. Transmitting the request takes some time, during which the message Transmitting request is displayed on the device display. Once received, the operator’s response is displayed on the display. Otherwise, the message No response is displayed. Heat calculator SPT 941 .20 complies with GOST R EN 1434-1-2011, GOST R 51649-2000, MI 2412-97, GSSSD 187-99, TR TS 004/2011 and TR TS 020/2011.
