    4. TRANSPORTATION AND STORAGE RULES Automation boards MCB, mini MCB produced by Salda UAB shall be transported and stored by following the following rules: › Components on the boards are easily vulnerable, therefore it is necessary to protect them against mechanical impact – shocks, crushing, compression, etc.;...

  • Page 5: System Control

    In Stand-by mode the system is shut down for a permissible period (based on the Stand-by mode blocking function settings). The Building protection mode is designed to protect premises against moisture accumulation. The system operates at speed 1. Based on manufacturer’s parameters (by default) this mode controls the temperature (the desirable one is indicated), but, if necessary, it can be switched off, i.e.

  • Page 6: Indications Of Functions, Alarms And Warnings

    Closing dampers Dampers are closed Night cooling Active night cooling Critical alarm Critical failure, system is shut down (for details refer to alarms section) Fire alarm Fire protection from an external contactor is activated Heat exchanger frost protection activated Heat exchanger frost protection is activated Warning about clogged filters (pressure switches are activated or filter timer Change filters is activated)

  • Page 7: Winter/Summer Mode

    5.8. WINTER/SUMMER MODE The winter/summer function is set during the cold periods, because some parts of the system have to be protected against cold outdoor air. During winter it is recommended to leave the unit switched on, therefore it is possible to set blocking of switch-off. Water heaters must be always switched on during the entire winter.

  • Page 8: Display And Cancellation Of Alarms And Warnings

    5.13. DISPLAY AND CANCELLATION OF ALARMS AND WARNINGS The system notifies the user about the system failures by warnings that are canceled automatically and by alarms that have to be canceled man- ually. The latter are recommended to be canceled by a specialist prior to finding out the causes of the alarm. Information on alarms and warnings is also displayed in the main window ADJUSTER ›...

  • Page 9: System Versions And Running Time

    This tool is designed for preventive maintenance of the system. 5.20. MODULE IDENTIFICATION Three expansion modules can be connected to the main MCB board: › EX1 module (module to control a heat recovery unit); › EX2 module (power module with relays);...

  • Page 10: Automatic Cancellation Of Failure Warnings

    5.22. AUTOMATIC CANCELLATION OF FAILURE WARNINGS This function is intended for the automatic elimination of freezing-related breakdowns after a certain period of time. E.g., if the unit was shut down due to critical frost protection conditions, then after some time the system can try operation again. The period is indicated in hours. If 0 is set, the system waits until the user cancels the failures manually.

  • Page 11: Fan Speed Dependence On External Contactor

    5.27. FAN SPEED DEPENDENCE ON EXTERNAL CONTACTOR This function is designed to activate/deactivate the boost ventilation or preferred combination of fan speeds by means of an external contactor. It is necessary to indicate a type of a signal to be sent to the input and what this function will control. Possible combinations of signal types and functions: ›...

FAN CONTROL The preferred air-flow can be indicated in percentage or in 4 fixed speeds where each of them is dedicated to a relevant system mode: ›...

  • Page 13: Exhaust Air Fan Control According To The Supply Air Fan

    The exhaust air flow is controlled automatically by maintaining the nominal relation of the air flows. This function requires pressure transducers, which measure the supply air and exhaust air flows. If MCB inputs are not sufficient, it is possible to use the pressure converters through Modbus communication line.

  • Page 14: Testing Of Fire Dampers

    The outdoor air recirculation dampers shall perform the following: › Heat-exchanger deicing function; › In stand-by mode full recirculation (blocking of outdoor air). The supply and outdoor air recirculation dampers shall perform the CO reduction function. If the outdoor air recirculation damper is activated, then it is necessary to assign 0-10VDC output for its control. outdoor air supply air extract air...

  • Page 15: Protection From To High Condensate Level

    5.35.3. PROTECTION FROM TO HIGH CONDENSATE LEVEL If there’s too much condensate, the condensate pump transmit signal to MCB board. The user receives warning immediately. If the signal is active for more than 60 min, airflow will be reduced till minimum. The protection will be disabled automatically after the signal discontinues.

  • Page 16: Heaters

    5.36. HEATERS 5.36.1. SUPPLY AIR HEATER The heater additionally pre-heats the supply air when the heat exchanger power is insufficient. It is controlled by means of a PID controller based on the temperature indicated in the system and based on data of the supply air temperature sensor. One supplied air heater can be connected to this system.

  • Page 17: Outdoor Air Water Pre-Heater Frost Protection

    This function is designed to automatically adjust the defrost intervals (using external controller) by monitoring the time of this process. Modbus communicates the dynamic time interval settings from the MCB to the heat pump controller. This function specifies the required initial interval between defrosting and the defrosting time (e.g. 3 min.). After defrosting, the automatics com- pares how long this process lasted.

  • Page 18: Sensors Adjusting

    The overrun limits are also specified for each sensor. 5.40. COMMUNICATIONS LINE CONFIGURATION MCB controller has two independent communications lines. One of the lines is dedicated to remote control panels, another one – to BMS network. The latter is galvanically insulated. Communication protocol – Modbus RTU.

  • Page 19: Cooking Hood Failure Indication

    This function terminates a service and adjuster session every 60 minutes. If a service worker or adjuster forget to log out from the service or ad- juster environment, then the controller will automatically lock the environments with passwords after 60 minutes. 6.
