Relays
Illustration 12 g02640537
A relay is an electrically operated switch. Relays use an electromagnet to operate a switching mechanism mechanically. Relays are used where necessary to control a circuit by a low-power signal, allowing complete electrical isolation between control and controlled circuits. When an electric current is passed through the coil, a magnetic field is generated activating the armature. The consequent movement of the movable contact either makes or breaks (depending upon construction) a connection with a fixed contact. When the coil is energized with direct current, a diode is often placed across the coil. The diode dissipates the energy from the collapsing magnetic field at deactivation, avoiding a dangerous voltage spike to semiconductor circuit components.Relays are used for the following functions on this machine:

Propel A and B
The machine propel speed is selected with the right joystick button. The signal for the creeper/standard speed button is sent to the control module. The control module communicates the request to the Master module via the J1939 Data Link. The Master Control module relays the signal to the propel solenoid. The propel solenoid is connected to the control valve. When the Master Control module opens the Propel solenoid (high speed request), the swash plate on the drive motor is at a minimum angle. Under this condition, the machine will be driven by high speed and low torque. When the Propel solenoid is closed, the swash plate will move to the maximum angle. Under this condition the machine will be driven by low speed and high torque.Forward Travel Operation
When the lower portion of the travel pedal is depressed, piston motors rotate clockwise and the machine moves in a FORWARD direction. Pilot pressure is directed to the brake defeat valve that is in piston motor. Pilot oil then travels to the forward servo piston that is in piston pump. The oil from the pump flows through line to motor. This causes piston motor to rotate clockwise. Return oil from motor flows through line and the return oil flows back to piston pump.Pilot pressure will move the forward servo piston and the displacement control valve to the left for forward travel. The displacement control valve will direct a charge pressure to the pump servo piston. As a result, piston pump will upstroke in the forward direction.As piston pump upstrokes, flow increases to piston motor. Piston motor will turn in the forward direction. System pressure will be directed through the brake defeat valve to the left end of the displacement control valve. The displacement control valve is held in position by spring force.Reverse Travel Operation
When the upper portion of the travel pedal is depressed, the swashplate of piston pump is tilted rearward. Piston motor will rotate counterclockwise and the machine moves in the REVERSE direction. Pilot pressure is directed to brake defeat valve that is in piston motor. Pilot oil then
