•P key

−Switches over between parameter number (parameter mode), parameter value (value mode) and index number (index mode) on indexed parameters.

−Acknowledges active fault messages.

−P and RAISE keys to switch a fault message and alarm to the background to get access to the parameter mode.

−P and LOWER key to switch a fault message and alarm from the background back to the foreground display on the PMU.

• UP key ( )

−Selects a higher parameter number in parameter mode. When the highest parameter number is displayed, the key can be pressed again to roll over to the lowest parameter number.

−Increases the displayed parameter value in value mode.

−Increases the index number in index mode (for indexed parameters)

−If the DOWN key is pressed, then, also pressing the UP key will accelerate the DOWN adjustment process.

• DOWN key ( )

−Selects a lower parameter number in parameter mode. When the lowest parameter number is displayed, the key can be pressed again to roll over to the highest parameter number.

−Decreases the displayed parameter value in value mode.

−Decreases the index number in index mode (for indexed parameters)

−If the UP key is pressed, then, also pressing the DOWN key will accelerate the UP adjustment process.
