Abstract

A fail-safe electronic position monitoring system for a motor is specifically described in a flame safeguard system. The same fail-safe system could be used more generally in any type of positional monitoring system using a potentiometer. The potentiometer and its wiper are monitored by a microcomputer which has stored in its memory a profile of at least three critical parameters. The parameters are a low voltage parameter, a high voltage parameter, and a parameter that deals with the rate of the voltage level change. The rate voltage level change includes monotonocity function.
