"Additional" («Дополнительно») tab

 
"Additional" («Дополнительно») tab in Rectification mode
1

Stepper motor speed

Steps per second while running the current program line.
 
2

Steps

Current steps is how many steps have already been made in the current line; Target steps is how many must be made before it ends.
 
3

Water flow

Total liters and rate in l/min from the flow sensor. The block is visible only when the sensor is connected.
 
 
Samovar 7.00: the "Speed, l/h" («Скорость, л/ч») field with the "Set" («Установить») button, the "Lock hearts take-off T" («Зафиксировать Т отбора тела») button and the system parameters line have been moved to the "Rectification" («Ректификация») tab (the main one). Their description is kept on this page.
 
Speed, l/h ("Rectification" tab)
 
Manual entry of the take-off rate for the peristaltic pump. It has priority over the program. It applies provided the program is already running and after the "Set" button is pressed. Take-off at the set rate continues until the next line starts.
 
Stepper motor speed
 
How many steps per second the stepper motor makes while running the program currently being executed.
 
Steps
 
Current steps is the number of steps already made in the program currently being executed.
 
Target steps is how many steps are left to make before the currently running program ends.
 
Water flow
 
Coolant flow data. Total (liters) and rate in l/min. Shown only if a flow sensor is connected.
Note.
Keep in mind that the flow sensor reads with a very large error, which depends strongly on the flow rate. So, by and large, it can only be used to check that water is present and for a very rough estimate of the flow. It can be calibrated in the Samovar_ini.h file, line #define WF_CALIBRATION 98.
 
System parameters ("Rectification" tab)
 
Shown on the main page in the "System" («Система») line. Information about the state of the cooling pump has been added.
 
Heap - the amount of free dynamic memory in bytes
 
BME temp - the temperature on the pressure sensor chip. In effect, the temperature inside the enclosure with the ESP32 installed
 
RSSI - an indicator of the power level of the received WiFi signal.
 
Free («Свободно») - free space in the Samovar file system in bytes. The process log is written here.
 
Water pump PWM («ШИМ насоса воды») - the current PWM duty of the cooling pump, if Samovar controls the pump.
 
Note.
The RSSI value is measured in dBm. The minimum value acceptable for network operation: RSSI = -85 dBm. Important! The higher the RSSI number, or the less negative it is, the stronger the signal (for example, -48 is greater than -78).
 
Lock hearts take-off T ("Rectification" tab)
 
Set new Steam and Column section temperatures.
Explanation.
Samovar records the Steam and Column section temperatures at the moment heads take-off ends and the "Hearts" («Тело») or "Pre-flooding" («Предзахлеб») program starts. At this moment power is usually increased to improve separation and late heads are taken off. After the power is raised, the temperatures may go outside the setpoints specified on the Temperaturetab. Samovar will then pause the take-off and wait for the temperatures to return to the recorded values. Pressing the button makes the current Column section and Steam temperatures the main ones, and take-off resumes accordingly. Samovar confirms this with the message "New hearts T: steam = …, column section = …" («Новые Т тела: пар = …, царга = …»).
