Abstract

A method of performing temperature-based diagnostics for motor starters within a physical grouping of motor starters is performed by determining a presently expected temperature operating range for each starter based on measuring operating temperatures of the starters; measuring their current draws, and evaluating the temperature and load draw data in light of compensation values assigned for the known power ratings of the starter and the starter's physical location within the grouping. With the presently expected temperature operating range of the starter determined, and the periodic monitoring of starter temperatures, when an individual starter's temperature exceeds its expected range, a diagnostic warning will be issued for that starter and/or for the control panel itself as a guide for preventative maintenance. Alternately, the warning may be issued for an unexpected temperature rise for a given rise in current draw, or for values exceeding an expected rate of temperature change.
