ELECTRICAL SYSTEMFORM NO. 56043089 / AquaRide ™ / BRX 700 - 57PROGRAMMING VEHICLE SPEED CHANGESThe maximum high-speed M1 (transport) and maximum low speed M2 (scrub) can be changed electronically, using the handheld programmer. Tochange a parameter using the programmer, press the PROGRAM key, and scroll down the Program Menu until the desired parameter is the topline of the display. Press the appropriate CHANGE VALUE key (“up” or “down”) until the desired number is reached. The parameter is now set atthe desired value. All programming occurs in real time. In other words, the parameters can be changed while the vehicle is in operation.The upper and lower limits of parameters are set at the factory. Some parameters have dependencies on other parameters. When the programmeris being used to adjust a parameter and a limit is reached, the display will stop changing. To see why the display has stopped changing, press theMORE INFO key. If the limit is related to another parameter, that information will be displayed; changing the value of the related parameter mayallow the original parameter to be adjusted further. Otherwise, the display simply says “Max Limit” or “Min Limit.”Use of the programmer is described more fully in the PROGRAMMER OPERATION section of this chapter.MAINTENANCEThere are no user-serviceable parts inside the Curtis PMC 1228 controller.
