TIC LEXION 500 Electric System
03/05 Lex-e-10a 10a-3
Description of function:
Fan variable-speed drive When the threshing mechanism is engaged, relay K14 actuates relay
K63, thus supplying relays K37 and K38 with earth at pin 85. A CAN bus
signal is transmitted to the fieldwork computer module (BIF/CAB) A10 by
the +/- pushbuttons (T19/T26) provided that the function pre-selection
rotary switch (T11) is set to the fan position. The fieldwork computer
module (BIF/CAB) A10 actuates the corresponding relay K37 or K38 via
pin 86.
The fan speed adjustment electric motor (M3) is supplied with earth
according to the sense of rotation by one of the relays K37/K38 from pin
87a whereas the other relay K37/K38 controls the voltage on pin 87.
The fieldwork computer module (A10) ensures actuation of the relays K37
and K38 during automatic crop selection.
The fieldwork computer module (A10) reads in the fan speed actual value
via fan speed sensor B15 during automatic crop selection.
Fan speed display The fieldwork computer module (A10) reads in a signal from sensor B15
(fan speed). The fieldwork computer module (A10) converts this signal
and displays it on terminal A30 via the CAN bus – see also diagram 25a.
