The pump pressure or engine speed setpoint is controlled by the + and – buttons on

1.4 Operation
The FPG has six modes of operation that are used for specific pump and engine control applications:
initialization, ready, speed control, pressure control, high-idle control, and idle. The configuration mode is
used to edit FPG system parameters. The configuration mode menu can only be entered from the ready
mode when the FPG is not controlling the engine. The following sections detail the operation of the FPG
control modes, the required interlocks, warnings, and alarms.
