RING-BACKUP 3K8692 - Caterpillar

The multi-position throttle switch is an optional throttle input. A maximum of four switches can be used. Four switches will allow a maximum of 16 speeds to be selected.When the multi-position switch is selected as the "Throttle Type" on the "Throttle Configuration Screen" of the electronic service tool, additional information is required.Number of Switch Inputs
This parameter is the total number of switches that will be used. The switches may be individual switches or a ganged rotary switch.
Table 1
Range    Default    
1 to 4     1    Physical Position
This parameter is non-programmable. The parameter is used to signify the position of the rotary switch.Input 4, Input 3, Input 2, Input 1
The number of these non-programmable parameters that are visible depends on the value that is programmed into the "Number of Switch Inputs" parameter. "Open" signifies that the switch is in the OFF position. "Ground" signifies that the switch is in the ON position.Physical Position Enabled
If "Yes" is selected from the drop-down menu, the ECM sets the engine rpm to the value that is programmed into the "Engine Speed" for the configuration of the switches that is defined for that Physical Position.

Value    Default    
No
Yes     No    Logical Position
The Logical Position is the order that is required by the user for a unique Physical Position.
Table 3
Range    Default    
1 to 16     1    Engine Speed (in RPM)
The "Engine Speed" is the programmed engine rpm for a particular position of the multi-position throttle switch.If the ECM detects a switch combination that has been configured as "No", a fault code will be generated. In this situation, the ECM will ignore the multi-position switch until the keyswitch is cycled through OFF and ON.
