Preset Programming
Changing the preset RPM or Pressure
Holding the PRESET switch as the first function after the governor Power On Cycle accesses the gover-
nor PRESET programming function.
Apply power to the controller and hold the preset switch until the display indicates PRESET, then re-
lease the switch (approx. 10 seconds).
Typically , the RPM Preset is an engine speed that either enhances alternator output or provides good
pump priming ability. Once set to department specification, it should not need to be changed.
The Preset Pressure is normally one that is set by the department for initial attack operation or a safe
pressure for pre-connects. If set too high, it could present a hazard to operators. The design intent is to
get the apparatus up and pumping in a minimal amount of time. Once the truck is operating, the pres-
sure should be adjusted to the operation being performed.
The display will show PRESET while in the PRESET programming mode.
The apparatus must be operating (engine running) to preset an RPM and the pump must be engaged to
preset a Pressure. The only indication of mode will be the two LED’s at the top left of the controller.
The green RPM LED will be illuminated in the Throttle Mode and the amber PRESSURE LED is illumi-
nated when operating in Pressure Mode.
Operate the controller using the INC and DEC switches until you attain the desired RPM or pressure.

To test the presets, select a mode and press the PRESET Switch. The governor should operate the
engine to the correct Preset Point for the mode you selected.
Presets can be set individually if desired.
