Setting up
The sensor status screen
How to read the status screen of a sensor — channel, address, type, link state, live figures and active alarms — and what each kind of sensor shows on it.
Reached through “Information” in the context menu of a sensor (Sensor settings). It shows what the panel knows about one sensor.
The screen
- “Channel #” — which sensor of the whole list this is.
- Previous sensor — or press “MINUS”. The screen stays open.
- Next sensor — or press “PLUS”.
- “Address:” — the address the sensor answers on. Not shown in this manual.
- “Type:” — the kind of sensor and its number, here hopper sensor 1. Some sensors show a line “Unit:” instead of the address — where they are connected, for example “Control panel”.
- “Link:” — the state of the communication. Table below.
- The figures of this kind of sensor — here the level on the input of a hopper sensor. Table below.
- “Alarm 1 from 1” — the active alarms, one at a time. “UP” / “DOWN” step through them.
- The name of the alarm shown.
| Button | Action |
|---|---|
| “PLUS” / “MINUS” | Next / previous sensor — the screen stays open. |
| “UP” / “DOWN” | Step through the active alarms of this sensor. |
| “MENU” | The context menu of this sensor. |
| “BACK” | Back to the sensor selection. |
Link states
| State | Meaning |
|---|---|
| “Normal” | The sensor answers. |
| “Not controlled” | The sensor is out of control: neither the communication nor anything else is watched. |
| “No connection” | The sensor does not answer. Red. |
| “Wrong device type!” | Something answers, but not the kind of device the profile expects. Red. |
| “IMITATION” | Speed sensor only: the speed is simulated, not measured. Yellow. |
The figures are drawn only while the sensor is under control, answers, and is of the expected kind. A sensor out of control shows its identity and nothing else.
What each kind of sensor adds
| Sensor | What the screen shows |
|---|---|
| Speed sensor | The pulse frequency F= in Hz; with two speed sensors F1= and F2=. Under it the two limits “Min speed, km/h” and “Max speed, km/h”. On a machine that doses a product by weight with electric motors, the limits are those the motors can hold, narrowed by the two settings; a limit the settings cannot meet is written in red as an inequality. Without such motors a limit set to zero is shown as ----, switched off. |
| Hopper sensor | Pin: and the level on the input, "0" or "1". |
| Dispenser shaft sensor | F= in Hz, to three decimals. |
| Fan sensor | F= in Hz. |
| Pressure sensor | P= in kPa. |
| Seed sensor, dry fertilizer sensor | Status: and one of eight states — below. |
| Liquid fertilizer flow sensor | Status: Working, or Working:Tramline in the tramline mode; under it Flow= in L/min. |
| Work position sensor | Position: Working or Position: Transporting, and Pin: with the level on the input. |
| Ignition, oil pressure, battery charge, fuel level, air filter | Pin: and the level on the input, "0" or "1". |
| Marker sensor | Only the common lines. |
| Tramline actuator | Status: Pulled in, Pulled out, Working while the shutter moves, or Unknown. |
| Dispenser electric motor | Status: Working, or Faulty while any alarm of the motor is active; then Last fault: with the controller's code, if there has been one (codes). A universal controller adds IN1[ ] IN2[ ] IN3[ ] with the levels on its three inputs. |
| Liquid fertilizer pump controller | Status: Working or Faulty. With a fault, Last fault: and the code. Without one: Flow= in L/min, Load= in per cent, and Pressure sensor: No if there is none, otherwise Pressure sensor= in Bar with the raw signal in mA in brackets. Dashes stand for a value the controller cannot give. |
The eight states of a seed or fertilizer sensor
| Status | Meaning |
|---|---|
| Working | Normal. |
| Working:Tramline | Normal; the sensor is in the tramline control mode for the current bout. |
| Configuring | The sensor has received new settings and is applying them. |
| Calibration in progress | The sensor runs its initial calibration. It takes a few seconds. |
| Clogged | The infrared emitter of the optical channel is blocked — most likely a blocked seed tube. Red. |
| Light struck | Too much sunlight falls into the optical channel; the sensor may miscount. Red. |
| Faulty | The sensor has failed and must be replaced. Red. |
| Unknown | Another fault that cannot be identified. Red. |
