CX EXCAVATORS
CURRENT CONDITION CHK2
• R: Engine Load Ratio (CX210/CX240)
• FT: Fuel Temperature (CX210/CX240)
• TV: Throttle Volume
• TR1: Transistor Output
• TR2: Transistor Output
• TR3: Transistor Output
• TR4: Not Used
R: CX210/CX240 Information sent from the engine controller to the main controller. The
main controller uses this information for recording purposes. The controller also uses
this information plus pump pressure to determine when to activate Auto Power Boost.
FT: CX210/CX240 Information sent from the engine controller to the main controller.
The main controller uses this information for recording monitoring purposes.
TV: Use this field to verify that the controller is receiving the signal from the throttle
control knob.
TR1, TR2, TR3: These fields can be used to verify that the controller is sending the
signal to turn these various circuits on and off as they are selected by the operator.
