Dispenser shaft sensor
The parameters of the dispenser shaft sensor — rotation control against the wheel, or weight control by the mass applied — with ranges and defaults.
The dispenser shaft sensor counts the turns of a dispenser driven from the ground wheel. The panel can watch it two ways: by its rotation against the speed sensor, or by the mass of product it applies. Touch and hold the metering unit icon on the home screen to open its context menu (Sensor settings).
| Parameter | What it does | Range, default | Level |
|---|---|---|---|
| “Period, s” | How long the shaft may give no pulse before it counts as stopped — and how long after the start of seeding or moving the panel waits before it expects rotation. | 1 … 60; 10 | Operator |
| “Rotation speed control” | Watch the shaft rotation against the travel speed. | “No” / “Yes”; “No” | Agronomist |
| “Wheel, pulses” | Set by the rotation calibration. Shown with rotation control on. | 1 … 65535; 100 | Agronomist |
| “Dispenser pulses” | Set by the rotation calibration. Shown with rotation control on. | 1 … 65535; 100 | Agronomist |
| “Maximum error, %” | How far the shaft speed may stand from the speed the travel speed asks for before “Low speed of rotation” or “High speed of rotation”. Shown with rotation control on. | 1 … 50; 10 | Agronomist |
| “Weight control” | Watch the dispenser by the mass applied instead of by its rotation. | “No” / “Yes”; “No” | Agronomist |
| “Type of product” | Which of the four products this dispenser meters. Shown with weight control on. | “Product 1” … “Product 4” | Agronomist |
| “Weight, gr” / “Weight, pulses” | Both set by the calibration by weight. Shown with weight control on. Number pad. | 1 … 65535 each | Agronomist |
Without a speed sensor in the profile, only “Period, s” is offered — both kinds of control need the travel speed. With “Weight control” switched on, the context menu also holds “Dispenser calibration(weight)”.
Calibrations
- Rotation — for “Rotation speed control”: Calibrate the dispenser rotation.
- Mass — for “Weight control”; repeat it whenever the product changes: Calibrate the dispenser by weight.
The status screen shows the shaft pulse frequency F= in Hz, to three decimals. Its alarms: Fan or dispenser shaft: speed alarms, and with weight control Dosing by weight.
