    Solution System Chapter. Functional Description Overview The CS7000 uses electricity to operate almost everything. The “Battery” model has a large capacity 36 volt storage battery for its only power source. Power from the 36v battery supplies all machine electrical loads.
  • Page 99 Service Manual – CS7000 Electrical System “Hybrid” models use a large, engine-driven 42 volt generator for their main power source with a smaller 36 volt battery pack connected in “parallel” with the generator, as a “back up”. When the engine is running the 42 volt generator provides the electrical power to operate the 36v machine electrical loads as well as recharge the 36v battery pack.

    Service Manual – CS7000 Electrical System All models have a large connector to disconnect power from the machine. A circuit breaker panel located on the left side of the operator foot well area provides circuit protection for multiple circuits. The electrical system makes use of hall effect current sensors to provide amp draw information to the main machine controller for some circuits.

    12 volts to switch out to various circuits like the Ignition output to the engine system. Current Sensors The CS7000 utilizes 3 hall effect current sensors to report amp draw information for the vacuum motors, scrub motors and main broom motor to the main machine controller. They work much like an inductive amp clamp for a digital multi-meter.
  • Page 103: Low Voltage Cutout

    Service Manual – CS7000 Electrical System Low Voltage Cutout The scrub system and solution system are cut off by the main machine controller if the system voltage falls too low (Approx 31.5v for “wet” batteries or 32.94v for gel batteries). This is done to prevent damaging the batteries from over discharging.
