operation
the operator resuming control of pump stroke by depressing the foot pedal after releasing.
Safety Interlocks
1.Error is detected in either Pedal Position Sensor, or Stroke Position Sensor.
2.Operator Presence is not detected.
3.Error Code is received from engine.
power management
1.Pump stroke command is scaled when engine load reaches a threshold capacity, maintaining maximum rotor speed and preventing engine from stalling.
2.The pedal will not be able to stroke the pump until the engine is at full RPM.
