Sirio entry 230 frequency converter circuit. By bank card upon receipt
This frequency converter has been developed to control pumps in domestic applications. Submersible pumps in wells, pumps in water supply and heating systems - this is exactly the area where they are well used. : Single-phase input and output. Three-phase motors are rarely used in everyday life. Single-phase design significantly reduces the cost of the product. The rather high price for this converter is apparently due to the increased demand for a very useful new product.
The sirio converter controls the pump using a pressure sensor, which saves energy by almost half. The power of the motors used with the converter ranges from 1500 to 2000 W. The pressure sensor (there is also a flow sensor) is structurally built into the converter (an inch and a quarter fitting). Settings are made using the remote control of the built-in controller. Please read the instructions carefully regarding hydraulic connections!
The electric motor used with the converter must be single-phase. Three-phase can also be used, but it should be switched to star and a phase-shifting capacitor should be used.
Setting up the sirio entry 230 frequency converter
In the main display menu, you can scroll to change the display in the following order: pressure and frequency, voltage and current, inverter temperature and display language. For initial setup, you should put the converter into standby mode (the control system is running, the engine is not), press the + and – buttons and hold them pressed for more than 5 seconds. The setup menu appears. It scrolls as before, using arrows. In this menu, use the + and – buttons to set the following parameters:
- Pmax – maximum pressure, pump stop;
- Dp.start – delta for starting the pump (hysteresis);
- P.dr.ru – dry operation pressure, pump stop;
- P.limit – maximum pressure, with complete shutdown;
- Pmax2 – another maximum pressure setting;
- Dp.stop – delta for overpressure protection;
- Unit – unit of measurement (bar or ft. per square inch);
- I.max – current limitation through the pump motor;
- Rot – direction of rotation, conditionally.
In addition, there is also an extended menu with many functions. All that can be said about the advanced menu is that the user of the pump, even a plumber, should not change anything there. The parameters available there are intended for service technicians who service frequency drives. If the consumer gets there and changes something there, then he must know exactly what he wants. Otherwise, he may have an excellent opportunity to find out prices for a new motor or converter (or both).
A hermetically installed and properly configured sirio converter, complemented by a 10-20 liter hydraulic accumulator, works quietly and unnoticeably, and perfectly maintains water pressure in the home system.

The main purpose of the SIRIO ENTRY 230 device is to smoothly change the frequency of the current (and, accordingly, the speed of the motor shaft) depending on the required fluid flow at a given time, in order to provide the pump with a given constant pressure in the system. According to the principle of operation, the device belongs to inverters (AC frequency converter). SIRIO ENTRY 230 was designed specifically for use in private water supply, in conjunction with submersible (borehole, well) and surface SINGLE-PHASE pumps with a power of up to 1.5 kW inclusive.
In addition to the ability to smoothly control the rotation speed, this device has the following important functions built into it:
- smooth start and smooth stop of the pump motor;
- low and high voltage protection;
- thermal protection (current);
- short circuit protection;
- protection against leaks in the system;
- inverter overheat protection;
- digital indicator of the pressure in the system.
Protection against dry running and protection against leaks is provided by a built-in flow sensor, which monitors the actual fluid flow and is very reliable.
Using two SIRIO ENTRY 230 devices, you can create an automatic pressure maintenance station based on two pumps connected in parallel. In this case, one converter operates in Master mode, and the other in Slave mode.
For correct operation of the device, the manufacturer recommends installing a 1-2 liter hydraulic accumulator in the system to prevent restarts caused by small leaks.
SIRIO ENTRY 230 helps solve another important problem - maintaining constant water pressure in the water supply system, regardless of fluid flow.
Pressure drops inevitably occur in a system with pumps controlled by a pressure switch. This type of pump automation is the most common, but has one drawback - inevitable pressure surges. Many people are familiar with when the pressure in the system is constantly “walking”: warm, comfortable water was just flowing, and after a few seconds the water became colder - we turn the mixer, everything is fine, but again not for long, etc.
A sensor built into the device constantly monitors the pressure in the system and, using feedback, changes the pump speed to eliminate pressure surges.

Sirio-Entry 230 2.0
Frequency converter Italtecnica Sirio-Entry 230
A frequency converter SIRIO ENTRY 230(manufactured by ITALTECNICA, Italy) is an electronic control device with frequency regulation that has no analogues.
SIRIO ENTRY 230 connects to a single-phase 230 V electrical network, and produces a single-phase voltage of 230 V at the output. The device allows you to create automatic water supply pumping stations that provide stable pressure in the water supply network, regardless of the level of water consumption. The amount of pressure maintained in the network is set in advance and can be easily adjusted by the consumer.
Device SIRIO ENTRY 230 controls the operation of pumps powered by a single-phase 230 V network.
Thanks to the use of inverter technology, the device SIRIO modulates the frequency (Hz) of the motor input current so that the pump shaft rotation speed (rpm) corresponds to the required performance. Thus, the pressure in the water supply system is always maintained at the same level, and the energy consumption of the engine is always proportional to the actual volume of water consumed by the system. This significantly saves energy.
Device SIRIO ENTRY 230 provides smooth start and stop of the pump, protection against “dry running”, protection against operation at low or high voltage in the electrical network, protection against constant leakage.
Two devices SIRIO ENTRY 230 can be combined into double booster blocks. In this way, it is possible to build a frequency-controlled pumping station consisting of two pumps, one of which is the master and the other is the slave.

<< Стрелка, направленная влево: прокручивает станицы меню в обратном порядке
>>Right arrow: Scrolls forward through menu pages
ON-Off/Reset: Switches the device from standby mode, and also reboots the device after an alarm and/or in an error situation.
“+” button: increases the parameter shown on the screen, and also makes the pump work at maximum performance without turning on dry-running protection.
"-" button: Decreases the parameter shown on the screen.
Main Menu Structure
The main menu displays the operating parameters of the system: pressure, pump motor frequency, input voltage, pump motor output current and temperature inside the inverter. On the main menu pages you can also select the language for working with the device.
Main menu
1. Home page: when Sirio is in standard operating mode, the first line on the screen displays the current pressure; and the second is the current frequency of the voltage supplied to the pump motor. In this mode, the user can use the cursor buttons to go to different menu pages; or use the “on-off” button located in the center to switch to standby mode.
2. When Sirio is in standby mode, the pump will not turn on, even if the pressure drops below the set value “P min”. To exit standby mode, press the button located in the center again. If the "+" button is held down, the pump starts to operate at its maximum operating speed, and the dry-running protection is disabled (use this function to prime the pump at first start-up).
3. Voltage and Current: This menu page displays the input voltage to the inverter and the current consumed by the pump. The amount of output current to the pump may differ from the input current, since the inverter modulates not only the frequency, but also the voltage.
4. Temperature: This page shows the temperature inside the inverter and IGBT power module. Both temperature indicators are taken into account by the energy saving system, which limits the value of the maximum voltage frequency supplied to the pump motor when the device’s alarm system reaches almost the maximum values.
5. Language: The language of menus and alarm messages can be selected by the user. Using the “+” and “-” buttons you can change the set parameters.
Sirio Entry 230 2.0 setup
1. Pmax: This parameter can be used to adjust the setpoint. This is an indicator of the constant pressure that the consumer wants to install in the system (max. pressure). In progress Italtecnica Sirio Entry 230 regulates the rotation speed of the pump shaft, adjusting it to the performance required by the consumption sources, thus maintaining constant pressure in the system. If the set value Pmax is greater than the maximum pump head, the pump will always switch off when the taps are closed. Sirio Entry 230 turns off the pump when the water flow through it drops below the minimum settings (approx. 2 l/min), regardless of the pressure reached in the system.
2. Delta P start-up: This parameter sets the negative delta (difference) of pressure in relation to the Pmax value for starting the pump. As soon as the tap of any consumption source is opened, the pump will not turn on until the pressure in the system drops below the Pmax value by an amount equal to the delta set by this parameter. After the pump motor starts, the device will adjust the shaft speed so that the pressure is as close as possible to the set value of the Pmax parameter. The minimum adjustable difference between Pmax and Pmin is 0.3 Bar, the recommended value is at least 0.5 Bar.
3. Dry-running pressure: this parameter only applies to operation when the flow sensor is not activated. Set the minimum pressure value below which the dry-running protection should be triggered (the pump motor runs at maximum frequency).
4. Pressure limit: This parameter sets the limit value for the overpressure protection to operate. Overpressure protection shuts down the inverter, requiring the user to reboot the equipment.
5. Pmax2: This parameter is used to program the second maximum pressure set point. When the auxiliary contact (or input on the auxiliary I/O board) is closed, the pressure value Pmax2 becomes the new set value according to which Italtecnica Sirio Entry 230 adjusts the rotation speed of the pump shaft.
6. Delta P stop: This parameter sets a positive delta (difference) in relation to Pmax to immediately stop the pump. In normal operation, when the taps are closed, the pump turns off after the time specified by the "stop delay" parameter. In any case, if the system pressure exceeds the Pmax value by a delta greater than that set in this parameter, the pump will stop immediately to prevent excessive pressure from building up, which could damage the system.
7. Unit of measurement: You must select the measurement system in BAR or PSI
8. Imax: This parameter is used to set the maximum current that can be drawn by the pump under standard conditions. If this value is exceeded, the pump will be stopped. The pump will also be stopped if the current during operation is below 0.5 A (this will interrupt the connection between the pump and Sirio Entry). The emergency protection time is inversely proportional to the overload value; therefore, a slight overload will result in a delayed shutdown, while a severe overload will result in an abrupt interruption of operation. When the device is turned on, if the I max value is set to 0.5 A (factory setting), then the page from which the maximum current value will be set will be displayed and the device will not operate until the maximum current value is set.
9. Rotation direction (Three-phase pumps only): From this screen page, the user can change the rotation direction of the electric pump without adjusting the wiring connection to the pump motor. The direction shown by the arrow should be considered arbitrary; it does not reflect the actual direction of rotation, which must be checked by the installer.
Advanced settings sirio entry 230
The end user does not have access to a list of specialized parameters. All these options are located inside a hidden menu. These parameters can be changed in the following cases: optimization of inverter operation; solving problems caused by non-standard equipment installation conditions; calibrating pressure and flow sensors or checking the device operation log. To access the specialized options menu, press and hold the center button for approximately 5 seconds until the menu page showing temperature appears. In order to directly view one of the menu parameters, you must enter values from 0.0 to 5.9. Parameters 0.0 to 1.1 are the basic parameters available to the installer, while parameters 1.2 to 5.9 are specialized parameters, which are listed in the table below.
(1.2) Minimum frequency: With this parameter you can define the minimum current frequency at which the pump starts and stops. For three-phase pumps the recommended value is 25 Hz, for single-phase pumps 30 Hz. Be sure to check the technical information from the pump manufacturer to determine at what minimum frequency the electric pump motor connected to the system can operate normally.
(1.3) Pump stop frequency: only if the flow sensor is not activated. This parameter determines the minimum frequency below which the pump motor will be stopped. During equipment debugging, if the pressure value Pmax is reached and the motor frequency is less than this value, the inverter will stop the pump. If all water taps are closed and the pressure in the system is constant, the pump will stop in normal mode. If the pump does not turn off, increase the value of this parameter. Conversely, if the pump makes frequent restarts, reduce the stop frequency value.
(1.4) Pump motor rated frequency: Depending on which pump is used in the system, the rated output frequency from the inverter (50Hz or 60Hz) can be selected. Attention: an incorrect choice of the rated frequency can lead to damage to the pump; carefully study the technical data of the pump specified by the manufacturer.
(1.5)Switching frequency: This parameter sets the switching frequency of the inverter. It is possible to select values: 3, 5 or 10 kHz. Higher switching frequency can reduce the noise from the inverter, and makes the motor control more smooth. On the other hand, this can lead to an increase in the temperature of the electronic board elements; cause electromagnetic interference and potentially harm the pump motor (especially if a long cable is used). Low switching frequencies are recommended for large and medium power pumps, in systems where Sirio is located far from the pump; or at high ambient temperatures.
(1.6) Frequency correction: This parameter allows you to set the positive or negative deviation of the maximum frequency from the specified nominal value. Setting a negative offset (up to -5Hz) can be useful if you want to limit the maximum power of the electric pump and prevent power overloads. Whereas a positive deviation (up to +5 Hz) is when it is necessary to slightly improve the pump performance indicator. When reducing the rated frequency there is no need for any safety measures, while increasing this value must be carefully weighed, calculated and decided after consultation with the electric pump manufacturer. In this case, the maximum permissible current of the inverter must be taken into account.
(1.7) Soft-Start: This screen page allows the user to enable or disable the pump motor's "soft-start" function. When this function is activated, the pump starts gradually; and vice versa, the start-up for the time specified by parameter 4.7 will be carried out at maximum speed before the pump shaft rotation speed begins to be regulated.
(2.0) Flow sensor: This page allows you to enable or disable the built-in flow sensor. Factory setting - flow sensor activated, i.e. the pump will stop when the taps are closed, and the device will accordingly determine that the flow of water through the inverter has ended. The same principle applies to dry-running protection. In any case, a malfunction of the flow sensor may occur (if, for example, the system has not very clean water), which will prevent the pump from stopping correctly. In such conditions, it is possible to disable the flow sensor and Sirio will operate only based on pressure and frequency readings. In this case, for efficient operation of the inverter, it is very important to correctly adjust the parameters of the stop frequency and the response pressure of the dry-running protection. Moreover, when the flow sensor is disabled, it is necessary to install a hydraulic accumulator immediately after the Sirio, which will help regulate the pressure when the pump is stopped and prevent its frequent restarts. Remember to periodically check the pre-injection pressure in the tank.
(2.1) Device control mode (Command origin): Select the device control mode. If this parameter is set to PRES pressure, operation will be adjusted automatically based on system pressure readings. Otherwise, if manual control is selected, then in manual mode, through the device control buttons, you can set the start and stop values of the pump, as well as the shaft rotation speed. Attention: if the device is in manual mode, the dry-running protection and pressure safety limits are not activated. This mode may only be used temporarily, under the direct supervision of authorized qualified personnel. Be extremely careful!
(2.2) Auxiliary contact: Use this parameter to select the function associated with the auxiliary contact. The values that can be set are: "1<->» operation of Sirio as a stand-alone independent system or using an auxiliary contact linking two Sirio devices as part of a dual booster station (factory setting). « 2<- » для использования вспомогательного контакта, осуществляющего дистанционное управление пуском и остановом насоса « 3 х 2» для использования вспомогательного контакта, контролирующего вторую точку настройки давления (Pmax2). Дальнейшая информация, касающаяся проводного соединения, а так же трех разных режимов работы, содержится в разделе «СОЕДИНЕНИЕ ВСПОМОГАТЕЛЬНОГО КОНТАКТА».
(2.3) I/O board input function: Defines the function that the digital input of the I/O accessory board (optional) will perform. The following values can be configured: “OFF” input disabled. “ERR”: If the auxiliary input is closed, the pump will stop immediately and “External error” will appear on the screen. Use this function when you need to stop the inverter due to some external error. “2<-“ вспомогательный ввод используется для дистанционного управления пуском и остановом электронасоса; если аналогичное значение задано для параметра «Вспомогательный Контакт» ("Aux. Con"), то необходимо замкнуть оба контакта для запуска двигателя насоса (Логическое «И»). “3 X2” вспомогательный ввод используется для контроля над второй точкой настройки давления (Pmax2); если аналогичное значение задано для параметра Вспомогательный Контакт ("Aux. Con"), то необходимо замкнуть один из двух контактов для контроля над второй точкой настройки (Логическое «ИЛИ»).
(2.4) I/O Card Pin Function: Defines the function that the digital pin of the I/O auxiliary card (optional) will perform. The following values can be configured: “OFF” output is disabled. “ERR” (Error): Output is ON (closed contact) when Sirio malfunctions. “P.ON“ the pump is running: the output is switched on (contact closed) every time Sirio controls the switching on of the pump. “AUX auxiliary pump: allows you to control the operation of the auxiliary pump at a given speed. The auxiliary pump is activated when the pump controlled by Sirio is unable to meet the system's demand. The output is activated (contact closed) when the pump frequency reaches the maximum permissible value and the pressure drops below the minimum switch-on value. Attention: it is prohibited to connect a load exceeding 0.3° to the output relay! Carefully read the technical documentation supplied with the I/O option board to ensure correct connection of the external control panel.
(2.5) Delay on stop: This parameter allows the user to set how many seconds after closing all the taps the electric pump will stop. If the pump restarts frequently in low flow conditions, increase the delay before stopping to allow smoother operation. Increasing this parameter can solve the problem of frequent shutdowns of the device due to protection against dry running, especially in cases with well pumps, as well as pumps that have problems with self-priming. Factory setting - 10 sec.
(2.6) Auto-reset-interval: If the pump experiences a temporary lack of suction water during operation, Sirio will turn off the power to the pump to prevent damage to the pump. From this menu page you can set (in minutes) the automatic restart time. At the end of the set time, the device will test the system for the appearance of water at the suction. If the test result is positive, Sirio will automatically clear the error condition and the system will return to operational mode; if not, the device will try again after the set period of time has expired. The maximum allowed interval is 240 minutes (recommended: 60 minutes).
(2.7) Auto-reset test n.: This parameter sets the number of attempts Sirio will make to restart a pump that has been shut down due to dry running. Once the number of attempts is exhausted, the system turns off and requires direct user intervention to turn it back on. If this value is "0", the automatic restart function is not activated. The maximum allowable value for this parameter is 20. Using the “+” and “-” buttons you can change the set parameter.
(2.8) Total automatic reset: When set to ON, the automatic restart function is active for any error detected by the system, in addition to dry-running protection. Warning: Automatic and uncontrolled restarts due to certain system errors (such as overload) may eventually damage both the system and Sirio itself. This feature should be used with great caution.
ATTENTION: As of software version XX.06.00, the following pressure and flow sensor calibration parameters have been removed (moved) from the dedicated menu options. Please refer to paragraph 5 for sensor calibration! (3.0) Calibration of pressure sensor at 0.0 Bar: This page allows you to calibrate the pressure sensor at 0 Bar. Use this function after replacing pressure sensors or electronic boards.
(3.1) Calibration of pressure sensor at 5.0 Bar: This page calibrates the pressure sensor at 5 Bar. To bring the pressure value on the bottom line of the screen into clear correspondence with the actual pressure value in the system, use the + and - buttons. The pressure can be measured, for example, using an external pressure gauge. Use this function after replacing pressure sensors or electronic boards.
(3.2) Flow sensor calibration: This menu page allows you to calibrate the flow sensor when there is no flow. Use this function after replacing the pressure sensor or electronic boards.
(3.3) Pressure reading test: This shows the current system pressure. This screen can be used after the pressure sensor has been calibrated to verify that the system is sensing pressure correctly. The displayed value corresponds to the actual system pressure, as is normally displayed on the main screen.
(3.4) Flow switch reading test: This shows the current data of the flow sensor. This screen can be used after the flow sensor has been calibrated to verify that it is operating correctly. When the valve is completely closed (no flow), the displayed value should be ≤ 2.
(3.5) Software release: Device software version
(3.6) Power supply timing: This displays the number of hours the inverter has been supplied with power. This indicator can be taken into account when determining the equipment warranty (whether the warranty period has expired or not).
(3.7) Pump operating time: This reflects the number of operating hours of the pump, which can be used to compare the operating time of the pump and the power supply time of the device.
(3.8) Last error: This page shows the last error number in the system. This can be used to track down the last error that shut down a system that has already been restarted by the user.
(3.9) Pump start-up number: This shows the total number of starts of the electric pump connected to the system.
(4.0) Voltage boost at 0 Hz: This value shows (as a percentage) the voltage boost at 0 Hz to compensate for stator losses. If you increase this parameter, then, when the shaft speed drops, the voltage supply to the pump motor will increase.
(4.1) Dry run protection delay: On this page, you can set the delay value before the dry run protection operates. Increase this value if the system has a long suction line or the pump has a long prime time.
(4.2) Maximum starts per hour: This parameter sets the maximum number of starts of the pump per hour. To disable this protection, press the “-” button and hold until the word “OFF” appears.
(4.2) Anti-seize protection (every 24 hours): This parameter activates or deactivates the pump's anti-seize protection during periods of long periods of inactivity. Once this function is activated and until there is no water demand in the system, the pump will start every 24 hours to prevent the mechanical components of the pump (hydraulic seal) from seizing.
(4.3) Setting the device “dead time” (PWM dead times): sets the delay time between switching on one arm of the bridge. This setting may need to be changed to correct the average inverter output voltage when the switching frequency changes. The manufacturer should be consulted for further information and assistance in selecting the most appropriate value.
(4.4) Ki - Integral Constant: This parameter adjusts the value of the integral constant for the PID controller to ensure constant system pressure. If this value is increased, the output pressure value will be closer to the set point value (change error). If the value is too high, it may result in unstable settings (constant pressure fluctuations).
(4.5) Ki - Proportional Constant: This parameter adjusts the value of the proportional constant for the PID controller to ensure constant system pressure. If this value increases, the system becomes more sensitive to system pressure fluctuations. If this value is too high, it can lead to excess pressure or a sharp decrease in speed, with subsequent instability of the settings (constant pressure fluctuations).
(4.6) Boost time: This parameter sets the duration of the boost time when (flat start function is disabled) the pump starts at maximum frequency before the PID controller operates (PID controller setting). Increase this value if there are problems starting the pump (especially for single-phase pumps). Reduce this value if the duration of the rise period results in an undesirable increase in system pressure.
(5.0)Maximum Ambient Temperature: This parameter sets the maximum ambient temperature value that will trigger the trip thermal overtemperature protection. This parameter can only be changed upon receipt of special authorization from the manufacturer, as this may affect the safety of operation of the device.
(5.1) Maximum temperature of IGBT module: this parameter sets the maximum temperature value of the IGBT module, above which the trip thermal protection is triggered. This parameter can only be changed upon receipt of special authorization from the manufacturer, as this may affect the safety of operation of the device.
(5.2) Ambient frequency reduction factor: This parameter sets the reduction factor by which the inverter limits the maximum frequency of the pump when the ambient temperature is close to the set maximum. The reduction is activated when the ambient temperature approaches the threshold value set in parameter 5.0 by less than 5°C. As soon as the limit value is exceeded, the maximum pump motor frequency is reduced by a value equal to that set in this parameter for each increased degree of Celsius temperature.
(5.3) Frequency reduction factor based on IGBT module temperature: This parameter sets the reduction factor by which the inverter limits the maximum frequency of the pump when the IGBT module temperature approaches the specified maximum. The reduction is activated when the ambient temperature approaches the threshold value set in parameter 5.1 by less than 5°C. Once the limit value is exceeded, the maximum pump motor frequency is reduced by a value equal to that set in this parameter for each degree Celsius temperature increased.
(5.6) Minimum mains voltage: this parameter sets the minimum input mains voltage, below which the undervoltage protection is triggered.
(5.7) Maximum mains voltage: this parameter sets the maximum input mains voltage, above which the overvoltage protection is triggered. From this value you can calculate the voltage value (about 30V less), above which the pump slowly and more controlledly reduces the speed to prevent dangerous voltage fluctuations on the DC bus.
(5.9) Debug variables: This parameter is used to debug the device. It allows you to indicate certain internal technological processes to analyze their progress during operation of the device.

To delete information about a failure after eliminating the causes of the problem, it is usually enough to press the "reset" button located in the center, or turn off the power supply for a few seconds.
Sirio Entry 230(E0) - Low voltage: The power supply voltage is too low. Check the input voltage value.
Sirio Entry 230(E1) - High voltage: The power supply voltage is too high. Check the input voltage.
Sirio Entry 230(E2) - Short Circuit: This message will appear on the screen if the inverter output is short circuited, which can happen if the motor is not connected correctly, or the electrical insulation of the cables connecting the pump motor to the device is damaged, or the motor itself is faulty. pump When this error is reported, the electrical system should be inspected immediately by a qualified technician. The error can be corrected only by de-energizing the device, after which the cause of the error is eliminated. An attempt to start the inverter during a short circuit may damage the device and also pose a danger to the user.
Sirio Entry 230(E3) - Dry running: the system stops due to insufficient water in the suction. If the auto restart function is triggered, the Sirio will automatically make a series of attempts to check for water. To clear the error status, press the “reset” button located in the center.
Sirio Entry 230(E4) - Ambient temperature: The internal temperature of the device exceeds the permissible limits. Check the operating conditions of the inverter.
Sirio Entry 230(E5) - Module temperature: the temperature of the IGBT module exceeds the permissible limits. Check the operating conditions of the inverter, especially the water temperature and the current consumption of the pump.
Sirio Entry 230(E6) - Overload: this alarm message appears when the motor power is higher than the set current value (I max); this condition can be caused by extremely difficult operating conditions of the pump, too frequent restarts, problems with the motor winding; or there is a problem with the power cable between the pump and Sirio. If this alarm message appears frequently on the screen, the installer should have the system checked.
Sirio Entry 230(E8) - Serial Link Error: This alarm message may appear if there is an internal serial link failure in Sirio. Contact technical support.
Sirio Entry 230(E9) - Pressure limit: The set maximum pressure threshold has been exceeded. If this alarm message appears frequently, check the setting of the "P limit" parameter. Also check for other conditions that could lead to excessive pressure (for example, partial freezing of the fluid).
Sirio Entry 230(E10) - External error: This alarm message will appear when the input contact of the I/O auxiliary board is closed when the external error detection function is activated.
Sirio Entry 230(E11) - Maximum number of starts per hour: the maximum permissible number of attempts to turn on the equipment per hour has been exceeded. Check the system for leaks. Check the pressure in all hydraulic accumulators installed in the system.
Sirio Entry 230(E12) - Error 12V: An operating anomaly has been detected in the internal low-voltage power supply network. Send the device to the manufacturer for inspection.
Sirio Entry 230(E13) - Pressure sensor fault: the pressure sensor has detected an incorrect value. Send the device to the manufacturer for inspection.
