Information:
Open Loop Speed Control and Open Loop Steering Control
If a fault is detected in the left or in the right track speed sensor, the machine ECM uses the logic that is in the open loop steering control and the open loop speed control in order to control the machine. When this logic is used, the machine ECM monitors input from the following components:
The active steering sensor
The propel speed dial
The propel lever sensor
The decelerator sensor
The propel mode switch
The parking brake switch
The engine ECM (engine speed input)
The Caterpillar Monitoring System (harness code input)The machine ECM uses the harness code input in order to determine the target speed for the machine.The machine ECM generates output signals which are pulse width modulated at one of the combinations of the following terminals:
"J2-62" and "J2-64"
"J2-63" and "J2-65"The signals are sent to the forward or the reverse electric displacement control valve.Through these signals, the machine ECM controls the following:
The operating speed
The travel direction
The turning radius of the machineSince the left and the right speed sensors do not provide input to the machine ECM when the open loop speed control and the open loop steering control is used, the desired machine speed and/or actual machine speeds cannot be controlled. As a result, the machine may not track straight and/or the machine may exhibit erratic steering. The travel speeds will be limited to 50 percent of the maximum travel speed. The pave speeds will be limited to 50 percent of the maximum pave speed.Direction and Backup Alarm Control
In order to determine the target travel direction, the machine ECM monitors the input which comes to terminal "J1-24" from the active propel lever sensor. None of the electric displacement control valves are energized when the propel lever is in the NEUTRAL position. As a result, the machine will not move. When the propel lever is out of the NEUTRAL position, an output signal is directed to the appropriate electric displacement control valve. If the propel lever is in the REVERSE range, the machine ECM also directs a signal from terminal "J2-24" to the backup alarm. The signal causes the backup alarm to sound.Speed Control
The machine ECM monitors the input at terminals "J1-54" and "J1-55" in order to determine the position of the active propel mode switch. The machine ECM monitors the input at terminal "J1-24" in order to determine the position of the active propel lever. When the active propel mode switch is in PAVE position, the switch is open. The circuits at terminals "J1-54" and "J1-55" of the machine ECM are also open. When the propel mode switch is moved to the TRAVEL position, contacts 1 and 2 close. This completes the circuit at terminal "J1-55" of the machine ECM. When the propel mode switch is moved to the MANEUVER position, contacts 2 and 3 of the switch close. This completes the circuit at terminal "J1-54" of the machine ECM.The machine ECM does not direct an output signal from terminal "J2-45" to the shift solenoid in the following
