Traction
g288325
Note: The traction system will not engage if the operator is not in the seat or if
the parking brake is engaged.
To engage forward traction, the following inputs and qualifiers are required
(Figure 162):
•
Operator seat needs to be occupied (SEAT ON).
•
Parking brake must be disengaged (PARKING BRAKE OFF).
•
Traction pedal pushed to forward (FORWARD RANGE ON).
•
Traction pedal position sensor voltage should be within the range determined
during traction pedal calibration (TRACTION PEDAL (V) between FWD MAX
and FWD NEUTRAL on Traction Pedal Screen).
If the proper inputs and qualifiers exist, the following outputs should occur
(Figure 162):
•
Parking brake hydraulic solenoid valve S10 should be energized (output
not displayed on this screen).
•
Hydrostat solenoid S1 should be energized (HYDROSTAT FWD ON).
•
Hydrostat solenoid S1 output current should be within range (AMP FWD
0.640 to 1.800).
In neutral, the following conditions should be present:
•
Traction pedal position sensor voltage should be within the range determined
during traction pedal calibration (TRACTION PEDAL (V) between REV
NEUTRAL and FWD NEUTRAL on Traction Pedal Screen).
•
Hydrostat solenoid S1 output current should be zero (AMP FWD 0.000).
•
Hydrostat solenoid S2 output current should be zero (AMP REV 0.000).
Note: The traction system will not engage if the operator is not in the seat and if
the parking brake is engaged.
