OPERATION
On power-up the PumpBoss will be in the pressure mode of operating. The RPM
display will show engine at idle RPM, the three LED bar graphs will be green indicating
readings within normal ranges, and the message display will alternate between showing
the date and time.
If a monitored function is not within normal parameters the display will flash, the
RPM display will show an error or fault warning code and a description will show in the
message display. (Refer to Table 2. Error Codes or Table 3. Fault Warning Codes.)
If one of the inputs displayed by the LED bar graphs is not within normal range
the LEDs will be red.
When all necessary throttle enables are active and the interlock circuit is complete
the THROTTLE READY LED will light and the remote throttle will be controlling
engine RPM. The engine RPM control signal will be set at idle regardless of the control
knob position.
Controls
Control Knob
The control knob is used to adjust PSI and RPM settings. The PumpBoss will
sense how fast and in what direction the control knob is rotated and send a signal to
the ECM to increase or decrease the engine RPM proportionally.
If the control knob is rotated quickly; the engine RPM will change quickly.
If the control knob is rotated slowly; the engine RPM will change slowly.
• Rotate the control knob clockwise to increase engine RPM.
• Rotate the control knob counterclockwise to decrease engine RPM.
• Press the red IDLE button to immediately return the engine to idle.
