- Page 4 1 Overview The Dosistar VD series is a control unit for electrical pump systems. It is used for dosing and measuring fluids, especially in agriculture. It allows power control of electrical pumps while simultaneously showing the current flow and the total amount dosed on the display. The Dosistar VD series keeps the selected flow constant through optimised control algorithms.
- Page 5 2 Device description 2.1 Control and display elements Display Warning light two-line LCD Blinks when an display error or a warning occurs Indicator light Green light whenever the pump is running Control knob turning knob with push function connector With the knob all user inputs of the device are carried out. In addition, it serves for turning on and off the device.
- Page 6 3 Menu points The chapter titles are identical to the menu titles in the device itself. The order of menu points can vary depending on device type. 3.1 Advanced menu Here the extended menu can be made visible. By default, it is turned off when switching on the device.
- Page 7 3.2.1 Dosing functions The behaviour and the appearance of the dosing menu is dependant on the chosen dosing function. Here, a list of possible dosing functions gives a rough overview. A detailed description of the available settings can be found in the corresponding chapters. Customer specific dosing modes, that are not present in all devices, are not part of this manual.
- Page 8 3.2.1.3 Area dependant dosing Through vehicle speed and adjustable working width, the area per time can be calculated. The control algorithms then adjust the pump so that a constant amount per area is dosed. Changes in vehicle speed are automatically accounted for. Target value Dosing amount [volume/area] Measurements...
- Page 9 3.3 Adjust charge This menu point is only visible if Pump fixed charge has been chosen as dosing function. Here it is possible to enter a predetermined amount to dose. Choose the amount to dose (between 0 and 9999.9 liters) by turning the knob. The value is entered one digit at a time. 3.4 Working width This menu point is only visible if Area dependant dosing has been chosen as dosing function.
- Page 10 3.6 Choose dosing function The devices of the Dosistar VD series are very flexible. For different use cases there are three main dosing functions. Measure flow A Pump is controlled to achieve a constant flow rate and simultaneously current flow rate and dosed amount are shown.
- Page 11 3.9 Select cali value The calibration value is the number of pulses generated by the flowmeter if 1 litre flows through the flowmeter. It depends of the flowmeter and the viscosity of the liquid to measure. This menu selects the special calibration value for your process. By selecting this menu, the actual calibration value and its memory place is displayed.
- Page 12 3.11 Flow meter calibration The most precise way to obtain the right calibration value is to calibrate the device with the liquid you want to dose. This is done by dosing a known amount of said liquid while simultaneously counting the impulses generated by the flowmeter. Due to the nature of the calibration process the more accurate results require larger amounts to be dosed.
- Page 13 3.13 Language The device can use multiple different languages for its menu. Available languages are: German Englisch Estonian Dutch Finnish Danish French Additional languages can be added on demand. Contact us for more information. 3.14 Unit Depending on the use case the dosed volume can vary greatly. It is therefore possible to display the flow in different units.
- Page 14 An estimate of the typical motor current can be gained in the menu Work without flow meter. 3.19 Adjust alarm level The Dosistar VD series possesses a two-stage dosing alarm system: Underdose the red warning lamp flashes but the dosing process will continue...
- Page 15 3.20 Regulation The control algorithms of the Dosistar VD series of devices make sure that the target value is quickly reached and that disturbances are quickly eliminated. The control algorithms parameters have been fine tuned in many experiments in the field. However, in special cases it might be necessary to adjust these parameters.
- Page 16 3.21 Sensor functions A running dosing process can be interrupted with the pick-up switch. The pick-up sensor can, for example, be linked to the lifting mechanism of the mower. An optional wheel sensor can check for vehicle movement and is able to interrupt the dosing process if the vehicle stops. As pick-up switch, both opening and closing switches can be used.
- Page 17 3.23 Select wheel sensor The calibration value of the wheel sensor is the number of impulses generated when driving 100m. In this menu a calibration value can be chosen and be loaded from memory. When entering the menu, the currently selected memory location is shown with calibration value and wheel sensor name.
- Page 18 3.25 Adjust wheel sensor For the correct calculation of the vehicle speed, needed by the Area dependant dosing function (option Dosing L/ha in Choose dosing function), the number of impulses generated while driving 100m must be known. In this menu a known calibration value can be entered directly. Additionally, a unique name can be entered for every memory location.
- Page 19 In such a case contact your distributor. Master-password is exclusively for the service personnel of the IML Electronic GmbH. Repeatedly pressing the knob lets you skip the password entry so you can return to the main menu.
- Page 20 4 Connection The Dosistar VD has a central 10pin connector. This connector is used for all electrical connections. Pay special attention to proper wiring. Use the connection diagrams for orientation. The connector should be mounted with housing strain relief and cable kink protection.

All following alternative configurations only show changed single components. All omitted components are to be connected according to above default connection schemes A and B.

- Page 23 Current consumption of the sensors must not exceed 100mA 4. Use a sensor with npn-output (not recommended) The Dosistar VD series is not designed for the use with npn-sensors. However, if no other sensor is available, it is possible to use an npn-sensor in the described way:...
- Page 24 Test carefully! 5 Mechanical assembly The Dosistar VD series is fitted with a strong permanent magnet. It allows mounting the device on many metallic surfaces. If no magnetic surfaces are available, use the included retaining plate, which can be screwed to any appropriate surface.
