CONTROL MODULE DESCRIPTION
The ConvertaMAX™ 20/26 / BA 550/650 scrubbers have an electronic module that controls the activation of the scrub brush motors
for scrubbing and removal of the brushes/pads and the low voltage cutout function.
For normal scrubbing the brush motor(s) will activate only if the brushes are down and the Drive Paddle (5) (throttle) is in the forward
or reverse position.
For removal of the brushes/pads the scrub deck must be in the up position. To remove the brushes/pads simply depress the Brush
Remove Switch (15). The module will momentarily run the brush motor and then stop it quickly.
The low voltage cutout is adjustable for two different thresholds. The normal setting cuts out at 1.75 volts per cell and the alternate
setting cuts out at 1.83 volts per cell. The cutout level is selected by momentarily depressing the pushbutton switch located on the
module circuit board.
*Important Note: See the
Low Voltage Cutout Level Selection
manual section in the Electrical System and follow the instructions
for setting the low voltage cutout threshold.
DESCRIPTION OF THE BATTERY FUEL GAUGE
The Battery Fuel Gauge (12) uses a 10 bar LED display that indicates the state of the batteries charge, successively, bar by bar, from
full to empty. At 70% depth of discharge a single flashing light signals an energy reserve alert. At 80% of discharge, a double flashing
light signals an empty alarm. The battery gauge will retain the last state-of-charge condition even when the machine has been turned
off. The battery fuel gauge state-of-charge display indication is automatically reset to full charge when the battery pack is recharged.
