Travel speed: SLOWER, FASTER and speed sensor alarms

TroubleshootingHectare Mini firmware · 2.2.8

What to do when the Hectare Mini shows SLOWER or FASTER, when a speed sensor fails, or when the speed limits cannot be met.

The travel speed outside its limits raises no alarm window. The speed indicator on the home screen shows “SLOWER” or “FASTER” instead of the figure, as long as the speed is wrong — see Indicators. The limits are “Min speed, km/h” and “Max speed, km/h” of the speed sensor (Travel speed sensor); they are watched only while the panel is controlling the seeding.

“SLOWER”

What it means. The machine moves faster than “Max speed, km/h” permits.

What to check, in this order:

  1. Drive slower.
  2. The speed on the panel matches the real speed — compare with the tractor or a GPS.
  3. The settings of the speed sensor: “Pulses”, “Diameter, cm”, “Factor, %”, “Max speed, km/h”.
  4. Calibrate the speed sensor — Calibrate the speed sensor.
  5. The speed sensor itself is serviceable.

“FASTER”

What it means. The machine moves slower than “Min speed, km/h” permits.

What to check, in this order:

  1. Drive faster.
  2. The speed on the panel matches the real speed.
  3. The settings of the speed sensor, including “Min speed, km/h”.
  4. Calibrate the speed sensor.
  5. The speed sensor itself is serviceable.

While the speed is imitated, the indicator shows “INCREASE IMITATION” or “DECREASE IMITATION” instead: change “Imitation, km/h”.

“Speed sensor #1 failed” / “Speed sensor #2 failed”

What it means. Only with two speed sensors on an input device (“Input device (2)” in the profile): the machine moves, but this sensor has given no pulse for too long.

What to check, in this order:

  1. The gap between the sensor and its target, and the target itself.
  2. The connector and cable of the sensor up to the input device.
  3. The sensor itself — swap the two sensors; if the fault moves, the sensor is faulty.

“Error in settings of Min/Max”

What it means. On a machine whose motors dose by weight: a speed limit set on the speed sensor cannot be met together with the speeds the motors can dose at — the minimum lies at or above the highest dosing speed, or the maximum at or below the lowest.

What to check, in this order:

  1. The status screen of the speed sensor: it shows the limits in force and writes the impossible one in red — The sensor status screen.
  2. “Min speed, km/h” and “Max speed, km/h” of the speed sensor.
  3. The target rates of the products and the speed limits of the motors — Calibrate a motor by weight.
