Abstract
A programmable motor protector includes a protect module which connects through one serial link to a programmer module and through a second serial link to an RTD module. The protect module is a microprocessor which is programmed to monitor the values of various motor operating parameters and compare them against alarm limits and trip limits which are entered through the programmer module. In addition to indicating a trip or alarm condition, the system saves in a diagnostic table an image of the motor operating conditions at the moment a trip is detected. This diagnostic table may be examined using the programmer module.
