SWITCH AS-TOGGLE 1636711 - Caterpillar

System Operation Description:Use this procedure to determine if the circuit for the "PTO Engine RPM Set Speed Input A and Input B" is operating correctly.Background InformationThe Engine Control Module (ECM) can use various inputs in a number of ways. The inputs depend on the parameter programming. Certain features are available on several different inputs. The configuration for the switch must match the actual switch installation in order for the switch to function properly."PTO Engine RPM Set Speed Input A"The switch for the "PTO Engine RPM Set Speed Input A" controls the engine speed during PTO operation. The "PTO Engine RPM Set Speed A" parameter requires an engine RPM to be programmed. The "PTO Engine RPM Set Speed A" parameter is located in the "Dedicated PTO Parameter Group". The "PTO Engine RPM Set Speed Input A" status is also located in the "Input Selections Parameter Group". The engine will ramp up to the engine rpm that is programmed under the following conditions:
The switch for the "PTO Engine RPM Set Speed Input A" is in the ON position and the PTO On/Off switch is then turned on.
The switch for the "PTO Engine RPM Set Speed Input A" is turned to the ON position when the PTO On/Off switch is on.The "PTO Configuration" must be programmed to "Cab Switches", to "Remote Switches", or to "Remote Throttle" for this feature to function. The PTO On/Off switch or the switch for the "PTO Engine RPM Set Speed Input A "must be cycled from the OFF position to the ON position in order to return to the programmed engine rpm if the PTO operation is disabled. If the "PTO Engine RPM Set Speed Input A" parameter is programmed to "None" (default), this feature is not used. If the "PTO Engine RPM Set Speed Input A" parameter is programmed to "J1/P1-46", the feature is available. Also, the switch circuit should be connected to the same input.Switch for the" PTO Engine RPM Set Speed Input B"The switch for the" PTO Engine RPM Set Speed Input B" is used to control engine RPM during PTO operation. The "PTO Engine RPM Set Speed B" parameter requires an engine RPM to be programmed. The "PTO Engine RPM Set Speed B" parameter is located in the "Dedicated PTO Parameter Group". The "PTO Engine RPM Set Speed Input B" status is located in the "Input Selections Parameter Group". The function of the switch for the "PTO Engine RPM Set Speed Input B" is similar to the function of the switch for the "PTO Engine RPM Set Speed Input A". The engine will operate at "set speed A" when both of the switches are on. If the "PTO Engine RPM Set Speed Input B" parameter is programmed to "None" (default), this feature is not used. If the "PTO Engine RPM Set Speed Input B" parameter is programmed to "J1/P1:7" or "J1/P1:23", then the feature is available. Also, the switch circuit should be connected to the same input that is selected in the
