The scrubber is equipped with two high frequency electronic control units with energy recovery,. The unit 4Qbig (1 - fi g.15) controls the drI ve and the unit DCM06 (2 - fi g.15) controls
the squeege and brushes . This type of device also has diagnostics for any problems which might occur. The number of times the LED on the control unit fl ashes identifi es the type of
operating error which has occurred.
No. of Flashes / Error encountered (CONTROL UNIT "4Qbig" - FIG.15 - Pos.1)
Led OFF / The controller is off on with no errors
Led steadily ON / The controller is communicating wiht the terminal or the computer while the operator is chanching parameters
