4.7 ISOLATION CIRCUITRY DESCRIPTION
The EN1000 Series 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 section is to
explain how the circuitry accomplishes this isolation.
