TIC LEXION 500 Electric System
03/05 Lex-e-03a 3a-3
Description of function:
Time relay K58 The electronic circuit in time relay K58 delays the release circuit to the
individual consumers by approx. 1.5 sec. and therefore guarantees stable
operating voltage for the starting procedure.
Charging voltage warning Insufficient or absent charging voltage is indicated by alternator charging
light (H19).
At the same time, the analogue voltage signal of the alternator (G2) is
monitored by the fieldwork computer module (A10) and displayed as an
alarm in terminal (A30) if necessary.
Total failure of the alternator (G2) is reported as a defective V-belt of the
cooling water pump in terminal (A30) (see also diagram 1).
Coolant level warning The explanations regarding the coolant level warning can be found in
diagram 2a of the CAT diesel engine and diagram 2b of the DC diesel
engine.
Air filter maintenance
warning
The earth signal of the vacuum switch (Z69) is switched to terminal (A30)
and in parallel via the diode PCB (DI) to the transducer K57.
Temperature warning For a coolant excess temperature warning, the engine controller module
(A15) transmits the corresponding signal to the CAB module (A10) via the
CAN bus J1939. The CAB module (A10) converts this signal to the
CLAAS CAN bus, allowing display on the terminal.
At the same time and as a protective function, the diesel engine reduces
its maximum power.
Temperature display For coolant temperature display, the engine controller module (A15)
transmits the corresponding signal to the CAB module (A10) via the CAN
bus J1939. The CAB module (A10) converts this signal to the CLAAS
CAN bus, thus allowing display on the terminal.
Error code Active error codes according to ISO J1939 are displayed in terminal A30
in menu item "Engine loading".
