2.3 Theory of Operation
The B&C SP models use a single-speed motor to drive the cylinder via V-belts in all speeds. The
cylinder is supported by two spherical roller bearings located in a cast steel bearing housing or
split pillow block housings made of cast steel.
The motor is controlled by the computer control located in the front and the AC inverter drive
located in the rear panel. Any speed can be programmed for any wash cycle. Some speed ranges
are blocked out for programming due to safety reasons. These speed ranges are the ones that
the machine cannot operate at due to its spring or suspension resonance. This speed range is not
important and normally speeds for wash or extraction are not selected within this range. Any wash
speed in the range of 3-50 RPM and extraction speeds 150-Maximum RPM can be programmed.
Further any reversing action can be programmed. Normal reversing action is 16 seconds forward,
pause for 4 seconds, and 16 seconds reverse. Any temperature between 70F to 200F (20-95C) can
be programmed. Any water level in the range of the machine parameters can be programmed in
centimeters. The computer will automatically provide safety levels for steam injections and door
operations.
Water entry into the machine is through an air gap vacuum breaker utilizing electro-magnetic wa-
ter valves controlled by the computer. By utilizing the air gap vacuum breaker, backflow into the
water supply is impossible. The computer also controls the drain, supply dispenser, any external
liquid supplies, steam injection and any other vital functions of the wash program. The computer
can even record cycles and data of importance that could be used for maintenance purpose.
The steam, if installed, is injected in the bottom of the shell via a steam injector. The steam is
controlled by a steam valve that is programmed by the EL6 / FM7 micro computer.
The cylinder is perforated, allowing water to pass through and drain from within during drain
and extract steps. Lifting ribs inside the cylinder lift the load from the wash solution and allow
the load to tumble and falling back into the solution when the load reaches the approximate 10-11
