RPM Mode Operation
In the RPM mode of operation the RPM LED is on. The governor maintains a
constant engine RPM.
The pump discharge pressure can vary but, as a safety feature, the governor limits
the increase in pressure to 30 PSI over the last established PSI value. As the discharge
pressure approaches this limit the governor will automatically lower the RPM to prevent
a high pressure surge. The RPM LED blinks as the governor sets a lower RPM. This
lower RPM will be the new operating RPM setting.
Note: When changing from pressure to RPM mode during operations, hold
the MODE button for 3 seconds. The RPM setting is the RPM that the
pump was operating at in pressure mode.
1. Press and hold MODE button for 3 seconds.

2. Press PRESET and/or the INC DEC buttons to select RPM setting.
Result: Message display shows RPM setting, engine RPM changes.
3. Press IDLE button after operations to bring engine to idle RPM.
Result: Message display shows IDLE, engine at idle RPM.
