Pressure alarms: High pressure, Low pressure
What to do when the vacuum measured by a pressure sensor of the Hectare Mini is too high or too low.
The panel compares the absolute value of the measured pressure with “Minimum, Pa” and “Maximum, Pa” of the sensor (Pressure sensor), while the machine sows or moves in the working position. The device line names the sensor: Pressure sensor: #1.
“High pressure”
What it means. The measured pressure is above “Maximum, Pa” — too much vacuum.
What to check, in this order:
- Lower the speed of the fan or turbine.
- The damper of the air intake, if the machine has one.
- The tube to the pressure sensor: connected at the right point, not kinked, not blocked.
- “Maximum, Pa” of the sensor.
“Low pressure”
What it means. The measured pressure is below “Minimum, Pa” — too little vacuum.
What to check, in this order:
- Raise the speed of the fan or turbine.
- The damper of the air intake, if the machine has one.
- The air ducts and meters for leaks — hoses, seals, covers.
- The tube to the pressure sensor: connected at the right point, not kinked, not blocked.
- “Minimum, Pa” of the sensor.
The measured pressure is on the status screen of the sensor, P= in kPa — compare it with the limits, which are set in Pa (1 kPa = 1000 Pa).
