ELECTRICAL SYSTEM
CONTROL PANEL & COMPONENTS
The S-20 Series II bandsaw, with the "H" option, has been designed to provide the operator with a simple to use
interface that controls all saw functions. The electrical system of the S-20 Series II with the "H" option provides
power to the blade drive motor at the required voltage for the motor. The incoming power from source is provided to
the blade motor by means of a motor contactor and a motor overload. The contactor switches the power to the
motor and the overload provides protection from excessive current draw. The contactor overload is set to automatic
at the factory and provides quick reset if the overload "trips". All of the switches that the operator uses to operate
the saw are run with 120 Volts A.C. This control system is fed 120 Volts from a transformer that steps down the
"line" voltage to 120 Volts. The control wiring is protected by means of a fuse that is rated for 1.5 Amperes. The
following components make up the control wiring.
Any work performed on the electrical system should be carried out by qualified personell only.
