58. Error in height sensor 1
Height sensor 1 has a momentary erroneous value.
59. Error in height sensor 2
Height sensor 2 has a momentarily erroneous value.
60. Critical error in height
sensor 1
Height sensor 1 has displayed an erroneous value for an extended period of time.
Check the cabling, connectors and connections.
The sensor may be defective.
61. Critical error in height
sensor 2
Height sensor 2 has displayed an erroneous value for an extended period of time.
Check the cabling, contacts and connections.
The sensor may be defective.

Alarm list specific to Front Hopper
70. Fan speed too high
The fan’s speed is higher than the set
upper
alarm level.
Check the alarm limit settings that are programmed in the menu for alarm levels.
71. Fan speed too low
The fan’s speed is lower than the set
lower
alarm level.
Check the alarm limit settings that are programmed in the menu for alarm levels.
Check the rotation speed sensor cable, connectors and connections.
Check the sensor’s functionality by rotating the fan wheel manually and checking the
diode on the sensor. The diode should light up when the pin on the fan shaft passes the
sensor. The gap between the sensor and the pin should be between 1 and 2 mm. Adjust
if necessary. An illuminated diode is no guarantee that the sensor is working properly.
If the alarm appears only occasionally, this is probably because the sensor is either
incorrectly adjusted or defective.
72. Rotation sensor:
fertiliser
If the output rollers are not
moving
The output roller is stuck.
Check the power supply to the output unit.
Check the motor and the cabling to it.
If the alarm appears
despite rotation of the
output rollers
Check the cabling, contacts and connections.
The sensor is not emitting a signal.
73. Level sensor: fertiliser
Check the fertiliser level in the fertiliser hopper.
Check that the sensor is not dirty or damp. Wipe the sensor clean with a cloth.
Check the cabling, contacts and connections.
The sensor may be defective.
