Abstract
A control system for an industrial inverting type power supply is disclosed which provides for both operational control and a diagnostic capability for the power supply. The operational control aspects includes measuring and displaying a plurality of operational signals from within the power supply, and for providing several automatic modes of operation for the power supply. The diagnostic aspects of the control system include measuring and displaying a plurality of diagnostic values, particularly the measurement of several waveform characteristic values of the switching waveform of the power supply. Other diagnostic capabilities include a set of remote inputs, each of which, when activated, triggers an entry into a history table, thereby maintaining a record of remote input activations. Each remote input may also be configured with a descriptive message to be displayed on an operator display and a code which specifies the action that is to be taken by the control system when that remote input is activated. A short detection circuit is also included which operates when the power supply is stopped to test the switching elements of the power supply for shorts.
