The Programmable Engine Limits
Note: Before performing each test, reset the parameters to the factory defaults. This will ensure that a parameter that was used for one test is not active for another test. The parameters that are given in the tables must be programmed in order to perform the tests.The parameters that are given in Table 1 must be programmed in order to perform the following test.The tables have the rpm ranges for theMedium DutyEngines M/D ( 3126B, 3126E, C7, and C9). The tables also have the rpm ranges for the Heavy Duty Engines H/D ( C-10, C11, C-12, C13, 3406E, C15, C-15, C-16, and C-18).

"PTO Configuration"     Cab Switches    
"PTO Top Engine Limit"
The PTO Top Engine Limit can be programmed anywhere between the Low Idle Speed and the Top Engine Limit.     2100 rpm
2000 rpm H/D    
"PTO Cab Throttle RPM Limit"     PTO Top Engine Limit    
"Low Idle RPM"     700 rpm
600 rpm H/D    
"Idle RPM Limit"     900 rpm    
"Top Engine Limit"     2460 rpm C7, 3126B, and 3126E engines
2350 rpm C9

Frame 1    
Controlling Equipment    Action that was taken by the Operator of the PTO    Result    Resultant Engine RPM    
The Cruise Control switch is OFF. The PTO switch is OFF. The Set/Resume switch is OFF. The Fast Idle switch is OFF. The accelerator pedal is not depressed.     Park the vehicle with the engine at idle.     The engine is at the programmed Low Idle rpm.
Programmed Low Idle for H/D engines is 600 rpm.     700 rpm
600 rpm H/D

Frame 2    
Controlling Equipment    Action that was taken by the Operator of the PTO    Result    Resultant Engine RPM    
The Cruise Control switch is OFF. The PTO switch is OFF. The Set/Resume switch is OFF. The Fast Idle switch is OFF. The Accelerator Pedal is fully depressed.     Fully depress the accelerator pedal.     The engine is limited by the programmed "Top Engine Limit (TEL)". The TEL in this instance is 2640 rpm.
Programmed TEL for C9 engines is 2350 rpm.
Programmed TEL for H/D engines is 2120 rpm.     2640 rpm C7, 3126B, and 3126E
2350 rpm

Frame 3    
Controlling Equipment    Action that was taken by the Operator of the PTO    Result    Resultant Engine RPM    
The Cruise Control switch is ON. The PTO switch is OFF. The Set/Resume switch is in the Set position. The Fast Idle switch is OFF. The accelerator pedal is fully depressed.     Place the Cruise Control switch to the ON position. Place the Set/Resume switch to the Set position.     The engine is limited by the programmed TEL which is 2640 rpm.
Programmed TEL for C9 engines is 2350 rpm.
Programmed TEL for H/D engines is 2120 rpm.     2640 rpm C7, 3126B, and 3126E
2350 rpm C9
2120 rpm H/D    Note: The "PTO Top Engine Limit" (PTO TEL) can be programmed anywhere between the Low Idle Speed and the Top Engine Limit.

Frame 4    
Controlling Equipment    Action that was taken by the Operator of the PTO    Result    Resultant Engine RPM    
The Cruise Control switch is ON. The PTO switch is OFF. The Set/Resume switch is OFF. The Fast Idle switch is OFF. The accelerator pedal is released.     Release the accelerator pedal. Release the Set/Resume switch from the Set position.     The engine is at the programmed "Idle RPM Limit" which is 900 rpm.     900 rpm

Frame 5    
Controlling Equipment    Action that was taken by the Operator of the PTO    Result    Resultant Engine RPM    
The Cruise Control switch is ON. The PTO switch is ON. The Set/Resume switch is OFF. The Fast Idle switch is OFF. The accelerator pedal is released.     Turn the PTO On/Off switch to ON.     The engine will return to Low Idle rpm because a PTO rpm has not been set. The PTO On/Off switch will override the Cruise Control On/Off switch. The "PTO Vehicle Speed Limit" must be higher than the actual vehicle speed.     700 rpm
600 rpm H/D
