operation

engine throttle

The engine throttle has three primary speed settings: Idle, Charge, and Operating RPM.

1.Each press of the Throttle Switch (Figure 13) steps it from idle to operating speed if operator presence is

detected.

2.The speed defaults to idle at startup or when no operator presence is detected.

3.The speed defaults to full speed when the foot pedal is depressed and operator presence is detected.

Battery Management

Idle speed is raised automatically to prevent battery drain when:

„„ Hydraulic oil cooler fan is running. „„ Lights are on

„„ Battery voltage drops below preset voltage

Cold Start

1.Idle speed is raised automatically to expedite bringing machine to operating temperature when:

„„ Hydraulic oil is below preset temperature (Oil forces across relief valve to raise oil temperature).

„„ Engine coolant temperature is below preset temperature.

2.Aux 1 on indicator will light when machine is in cold start mode.

Safety Interlocks

1.Full engine throttle is allowed only when operator presence detected.

2.Engine speed changes to idle when operator leaves the seat or the foot pedal is released for more than a set period of time.

Pump Stroke

Stroke is proportionally controlled by the foot pedal input position via feedback from the stroke position sensor.

Safety Interlock

1.Pump is automatically de-stroked if operator presence not detected.

2.Upon startup, the foot pedal will not control pump stroke if the pedal is depressed unless it has been released after start up. This prevents machine from unintentionally moving when started.

3.Pump is automatically de-stroked if error is detected from foot pedal sensor.

4.Stroke position is directly controlled by foot pedal if error is detected from the stroke sensor.

cruise control

Setting the Cruise Control will set and maintain a set pump stroke position command.

1.Press the cruise control switch (Figure 14) to engage the cruise control. The cruise control switch LED indicator lights when cruise control is engaged.
