8.5 Water Pump
Models equipped with water pump
The solution flow rate is affected by the speed of the drive
system.
The controller adjusts the voltage to the pump to regulate water
volume.
The faster the machine is driven the more water will flow to the
brushes.
The controller uses stand still recognition circuitry. The pump
will be shut off, if the water supplied to the pump is to low or
inefficient, when the voltage supplied to the pump is above the 5
volt level. This feature is disabled if voltage is below 5 volts.
Solution Control
9. The Last Error
All models are equipped with an error memory which will indicate
the last error that occurred in the machine. This last error is displayed
upon turning on the machine by key switch. The first numbers that
appear will be the software version. The second will be the last error
(if one had occured). The third will be the hour meter.
If four digit error code is displayed continuously with blinking dots
and the alarm is sounding, the controller has detected a problem in the
system. The machine will be inoperable. See error codes for details.
