4.13 Exciter System

See Graphic: wc_gr002309

The machine has exciters on each drum. The exciters are driven by

gear-type hydraulic motors. The exciter motors are fed by a fixed-

displacement, gear-type hydraulic pump. The exciters are electrically

controlled. A switch (l) on the control console is used to select between

no vibration, front drum only vibration, or both drum vibration. When

activated, a light (i) on the control panel illuminates. A separate switch

(m) on the forward-reverse lever activates the electrical circuit that

controls exciter operation. The vehicle chassis is isolated from

vibrations by a series of shockmounts.

Exciter selector switch

Use the selector switch (l) to select the desired vibration mode:

Position 1 - vibration on front drum only.

Position 2 - vibration on both drums.

Exciter ON/OFF switch

To start vibration, press button (m).

To stop vibration, press button (m) again.

CAUTION: Do not leave the vibration running when the vehicle is to

remain stationary for some time. Leaving the exciter on for a prolonged

period when the machine is stationary may damage the exciter.
