Variable-Frequency Vibratory System
Illustration 2 g02105334
Variable frequency Vibratory System (1) Vibratory fuse (2) "B+" from main power relay (3) Gauge fuse (4) Optional vibratory tachometer (5) Optional vibratory sensor (6) Shift switch (7) Throttle switch (8) Amplitude selector switch (9) Vibratory control switch (14) Vibratory pump EDC (15) Diagnostic plug (16) Vibratory ECM (17) Vibratory frequency dial (18) Vibratory relay (19) Diode blockWhen the main power relay is energized, the 112-PU wire transfers power to vibratory fuse (1) and to gauge fuse (3). The 103-YL wire transfers power from the vibratory fuse to contact "5" of throttle switch (7). The 123-WH wire transfers power from the gauge fuse to vibratory tachometer (4) and to terminal "A1" of vibratory ECM (16). The tachometer is optional on the machine.Contact "5" and contact "6" of throttle switch (7) are part of the vibratory control system. When the throttle switch is in the LOW IDLE position, contact "5" and contact "6" of the switch are open. When the throttle switch is in the HIGH IDLE position, contact "5" and contact "6" of the switch are closed. When throttle switch (7) is in the LOW IDLE position, power does not transfer into the vibratory control circuit. When the throttle switch is in the HIGH IDLE position, the C906 -PU wire transfers power from contact "6" of the throttle switch to contact "9" of connector "E-C3/C-C5" and to contact "5" of shift switch (6) .The circuit wiring from here depends on how the machine is configured. If the machine is configured without a propel interlock, shift switch (6) is not part of the vibratory circuit. In this case, power transfers across contact "9" of connector "E-C3/C-C5" and is distributed to the following locations:
Contact "5" of amplitude selector switch (8)
Contact "2" of vibratory control switch (9)
Contact "10" of connector "C-C215/N-C6"
Contact "1" of connector "N-C9/N-C8."If the machine is configured with a propel interlock, the C906-PU wire in the connector "C-C5" is disconnected from contact "9" and connected to contact "11". In this case, the circuit wiring to contact "2" of vibratory control switch (9) is across contact "5" and contact "4" of shift switch (6) .When shift switch (6) is in the LOW SPEED position, contact "5" and contact "4" of the switch are closed. When the shift switch is in the HIGH SPEED position, contact "5" and contact "4" of the switch are open. When contact "5" and contact "4" of the switch are closed, power transfers from contact "4" of the shift switch to contact "11" of connector "E-C3/C-C5" through the C905-OR wire. From here, power transfers into the C906-PU wire and is distributed to the following locations:
Contact "5" of amplitude selector switch (8)
Contact "2" of vibratory control switch (9)
Contact "10" of connector "C-C215/N-C6"
Contact "1" of connector "N-C9/N-C8."From contact "1" of connector "N-C9/N-C8" power transfers through a jumper and becomes available at contact "2" of the connector. The C932- YL wire transfers power from contact "2" of the connector to terminal
