stored in a dry place.
If the cells are fouled, they must be cleaned with a soft brush.
WARNING: Disconnect the console's power supply before performing any welding operations on the tractor or seeder, to
prevent the system from being damaged.
Symptom
The console doesn't light up
The console displays HALP 88 or
HALP 00
The speed is not displayed
The surface area is not displayed
The quantity of grains is not
displayed
The nr of grains/ha display
oscillates significantly
The number of rows displayed is
different from the number for the

A fault on a row is not signalled by
an alarm
The element does not engage (on
rows fitted with disengageable
heads)
