  • Page 13 KNOW YOUR MACHINE FUNCTIONAL DESCRIPTION OF CONTROL PANEL: The controls on the Convertamatic were designed with one touch operation in mind. For single pass scrubbing the user can simply depress one switch and all systems on the machine will be ready to go. For most single-pass scrubbing operations, the operator should only need to use the middle switches on the control panel.

  • Page 14: Know Your Machine

    KNOW YOUR MACHINE DESCRIPTION OF INDICATORS ON THE CONTROL PANEL: In general, the following guidelines apply to the control panel indicators: A fl ashing green or yellow indicator means that a fault has occurred in the particular system. An example of this would be an over-current fault. A yellow indicator means that the particular function has been enabled but is not currently on.
