4.7  EN1000/EN1001 ISOLATION CIRCUITRY DESCRIPTION

The EN1000 Series of controls are microprocessor based resistance welding controls that
incorporate circuitry designed to prevent any output from the control due to spurious or
unexpected or false conditions or failure of circuit components.  The intent of this
application note is to explain how the circuitry accomplishes this isolation.
