ELECTRICAL SYSTEMFORM NO. 56043089 / AquaRide ™ / BRX 700 - 61Input Indicators:See Figure 9 for button locations. Note: the seat switch must be closed for any of the following three indicators to be lit.Battery status red indicator (K1):Speed control reverse signal. This indicator will be lit if the reverse signal from the speed control is active.Battery status yellow indicator (K2):Speed control forward/reverse signal. This indicator will be lit if the forward/reverse signal from the speed control is active.Battery status green indicator (K3):Speed control status signal. This indicator will be lit if the status signal from the speed control is active. If a speed control fault exists, this indicatorwill flash the fault code from the speed control. Refer to the speed control section for details on these codes.Status Display (G):If no over-current faults are present, the status display will show the battery voltage. This display is accurate to within +/- 0.15 volts. Therefore,the voltage displayed may not correlate precisely to a high-accuracy, calibrated voltmeter.• An example of how 36.0 volts would be displayed is as follows:• The display will show “3” followed by a brief blank period• The display will show “6” followed by a brief blank period• The display will show “_” followed by a brief blank period (serves as decimal point)• The display will show “0” followed by a long blank period• The above sequence will repeatIf over-current faults are present, the status display will indicate the error codes.Output Controls:See Figure 9. The control panel switches are used to control various output functions of the main control unit. Below is a list of each switch andthe function it controls. Following the list is a detailed description of each function.Scrub off switch (B): Controls brush motor(s).Maintenance mode switch (D): Controls scrub deck lift actuator.Restore mode switch (F): If this switch is pressed, the restore mode indicator will illuminate.Vacuum switch (O): Controls vacuum motor(s).Solution switch (R): Controls solution solenoids.Horn switch (N): Used to jog the actuator.Fast/Slow switch (L): Selects the various speed control speed limits.Wand switch (I): If this switch is pressed the wand indicator will illuminate.Scrub System Off Switch (B):This switch is used to toggle the state of the brush motor. Pressing and releasing this switch will alternately turn the brush motor(s) on and off. Theindicator provides the following status information:Off - Brush motor output is off and there is no brush motor current sensed.Steady Green - Brush motor output is on and there is normal brush motor current sensed.Brief On Green Flash – Brush motor output is off and brush motor current is being sensed (abnormal condition).Brief Off Green Flash – Brush motor output is on and brush motor current is not being sensed (abnormal condition).Flashing Red – Brush motor overload has occurred.SERVICE TEST MODE (CONTINUED)
