) 1 is seen only momentarily when the ON/OFF switch is moved to the ON position and then it changes to0. However, if the engine
is running during the test the 1 remains on.
a) Engine is stationary and the 540 RPM PTO is engaged; when the emergency plug is pulled out, the PC display shows E at
the PTO SOLENOID. E changes to 0 when the plug is refitted. This same function concerns also the 1000 RPM PTO
--- If the table marks above and the PC display marks agree with the given switch positions, but the PTO does not function, the
possible fault must lie in the emergency plug, in the solenoid valve or in the indicating lamp or their wirings are faulty.
--- If the output signals on the PC display differ from the marks in the table above, the central processing unit (ECS) is faulty and
should be changed.
E. Slip control
Input signals to ECS (DIGITAL INPUTS)
SLIP CNTR 1/0 (A2C/16) 0 1
Slip Control ON/OFF (OFF=switchinpos.0,ON=switchinpos1---5) OFF ON
--- If the marks above the thick line agree with the corresponding marks on the computer display, the input signals are OK.
If not, the fault lies in the switch or its wiring is faulty.
--- The radar and the gearbox speed sensor are checked according to the calibrating instruction on page 351/2 or according to
the instruction F on the next page.
Output signals from ECS (DIGITAL OUTPUTS)

) When the switch is in the ON position, disconnect the radar connector and drive the tractor at a speed of 3 km/h (power lift
activated in the position control mode). Alternatively one rear wheel can be raised and then start carefully to drive with a low gear
(4WD must be disengaged and the A/M switch must be in M position).
--- If the table marks above and the PC display marks agree, the signal is sent from ECS to the hydraulic lift. If the lower links do
not make a lifting correction the possible fault lies in wiring or the power lift electronics do not function.
--- If the marks on the PC do not agree with the marks above, the fault lies in the ECS which must be changed.
Others
Lift/lower switch (DIGITAL INPUT)
When the lift/lower switch is in the lowering position or in the middle position, there is 1 in point IMPLEMENT POS (A2C/20). When
the switch is in the transport position the 1 changes to 0.
Thermostart (DIGITAL OUTPUTS)
In point FUEL PREHEATER (A1C/22), there is 1 when the glowing is on, otherwise 0.
