General Information
The optional drum offset system shares a common hydraulic tank with the propel system, the vibratory system, and the fan system. The steering pump provides the oil to operate the drum offset system.

Propel Control System
(1) Machine ECM number-one
(2) Machine ECM number-two
(3) Rear clockwise solenoid
(4) Rear counterclockwise solenoid
(5) Display
(6) Steering angle position sender
(7) Offset angle position sender
(8) Propel lever
(9) Steering shunt solenoid
(10) Front counterclockwise solenoid
(11) Front clockwise solenoid Note: The blue lines in the above illustration indicate an input signal. The red lines indicate an output signal. The red and blue lines indicate two-way communication.Machine ECM number-one (1) energizes steering shunt solenoid (9) in order to enable the steering system and the offset system. Machine ECM number-one (1) monitors input signals from propel lever (8), steering angle position sensor (6) and offset angle position sensor (7).Machine ECM number-one (1) evaluates the input signals and determines if any output signals should be sent to steering solenoids (10) and (11). Machine ECM number-two works with machine ECM number-one in order to control offset solenoids (3) and (4).The amount of offset is shown on display (5). This parameter can be displayed in percent, mm, or inches.The drum offset system section of this presentation is divided into segments. The first segments show the location of all components on the machine which are part of the drum offset system. A brief discussion of each component is provided in these segments. The last section explains the operation of the electrical system and the hydraulic system. Schematics are used in this segment to trace current through the electrical system and hydraulic oil through the hydraulic system.
