8.4 Checking sensor ”ha” for function
After the computer has been checked as described in para. 8.2 and
8.3 and no error could be found, a possible error can then only be
caused by a wrongly fitted sensor or a defective senso r or sensor
cable. Check the sensor:
1. Unbolt sensor
ha
and magnet from the seed drill.
2. Connect sensor cable
ha
to the calculator.
3. Enter code
F.1
and briefly press key
ha
.
4. Pass the magnet immediately in front of the sensor (simulation
of impulses).
The calculator processes the simulated impulses and shows th is
by adding them in the display.
→
If the calculator does not process the impulses correctly the
sensor must be exchanged.
→
If the calculator operates properly:
Reduce the gap between sensor and magnet o n the seed drill.
