Switching Between Operating Modes
• No variation in discharge pressure or RPM occurs when changing between
pressure and RPM modes.
• When changing to RPM mode, the RPM setting is the RPM that the pump was
operating at in pressure mode.
• When changing to pressure mode the pressure setting is the pressure that the
pump was operating at in RPM mode.
When the engine is at idle RPM:
Press the MODE button and the governor switches modes immediately.
When the engine RPM is above idle:
Press and hold the MODE button for 3 seconds and the governor changes
modes. (This is to avoid an accidental change over if the buttons get bumped.)
Pump Discharge Pressure is High at Engine Idle
Once the governor has set the engine to idle, it can do no more to reduce discharge
pressures. To reduce discharge pressure the pump operator can gate incoming water,
reduce pressure at the intake relief valve, gate discharges, or disable the pump.
