Major Components Of The Vibratory Circuit (1) Propel range switch. (2) Fuse. (3) Vibratory control solenoids. (4) Throttle switch. (5) Vibratory on/off control switch. (6) Switch for the vibratory amplitude control. | |
The vibratory electrical system controls the hydraulic system for the drum vibration. The circuit turns the vibration system ON and OFF. The circuit also controls the vibration amplitude. In order to start the vibratory system, throttle switch (4) must be in HIGH and propel range switch (1) must be in LOW.
The following items are the major components of the vibratory circuit:
- propel range switch (1)
- fuse (2)
- vibratory control solenoids (3)
- throttle switch (4)
- vibratory on/off control switch (5)
- switch for the vibratory amplitude control (6)

Right Operator Control Console (5) Vibratory on/off control switch. (6) Switch for the vibratory amplitude control. (7) Control for the variable frequency. | |
Vibratory on/off control switch (5) is located on top of the propel control lever. The vibration control switch turns the vibratory system on and off. The switch for the vibratory amplitude control (6) is located at the right operator control console. The switch for the vibratory amplitude control is used to select the vibratory amplitude (HIGH or LOW).

Vibratory Circuit Operation (1) Propel range switch. (2) Fuse. (3) Vibratory control solenoids. (4) Throttle switch. (5) Vibratory on/off control switch. (6) Switch for the vibratory amplitude control. | |
When the key start switch is in the ON position, the main relay is closed and system voltage is present in wire 112-PU-10. The system voltage is present in wire103-YL when fuse (2) is okay.
If the propel range switch (1) is in LOW position, voltage will be present at wire C905-OR and throttle switch (4). The throttle switch (4) must be in HIGH position so that the voltage will be present at wire C906-PU.
When the vibration control switch (5) is pressed, the switch will close. The switch will create a path through wire B919-GNto the switch on the vibratory amplitude control (6). If the switch for the vibratory amplitude control is in the HIGH position, current is conducted through wire B920-GN to vibratory control solenoids (3). If the switch for the vibratory amplitude control (6) is in the LOW position, current is conducted through wire B921-WH to vibratory control solenoids (3) .
