1.5 Checking in case of
malfunctions
1. On-board voltage The on-board voltage should be between 10 and 16 volt under load.
2. Oil supply The oil supply from the tractor should be 35-60 litres/minute.
3. Reed switch on chassis
from serial no.
Check Reed switch in the end position of chassis
4. Checking the angle
transmitter
After switching on the control terminal, the angle transmitters are
automatically tested:
LED 10 lights up: no fault
LED 10 flashing once: front angle transmitter defective
LED 10 flashing twice: rear angle transmitter defective.
LED 10 flashing three times: both angle transmitters defective.
The flashing mode is repeated every 15 seconds.
The signal voltage of the angle transmitters should be between 0.5 and
4.5 volt.
Measuring range of angle transmitters: 120°
Signal voltage at 0° = 0.5 volt
Signal voltage at 120° = 4.5 Volt
The signal voltage requires that:
the supply voltage be correct,
the angular sensor be correctly adjusted.
If the signal voltage is not in the target range between 0.5 and 4.5 volt,
the fault is indicated by the flashing code.
5. Manual operation Activate manual operation and perform the individual functions.
If the functions are performed flawlessly, check the angle transmitters
one more time.
6. Re-initialisation If the angle transmitters are OK, the machine should not be set to the
basic values one more time.
7. Switching on automatic
functions
Switch on automatic functions if not OK, load program one more time
(DOWNLOAD).
The program is loaded using the CDS (CLAAS Diagnosis System), this
requires:
• a download cable: part no. 935 890.0
• the instructions: part no. 959 049.0
When no remedy to the fault can be identified, replace the CCU.
