FAIL-SAFE POTENTIOMETER FEEDBACK SYSTEM

A fail-safe electronic position monitoring system (55) for a motor (16) is specifically described in a flame safeguard system (11). The same fail-safe system could be used more generally in any type of positional monitoring system using a potentiometer (18). The potentiometer and its wiper (19) are...

More Information
Summary:A fail-safe electronic position monitoring system (55) for a motor (16) is specifically described in a flame safeguard system (11). The same fail-safe system could be used more generally in any type of positional monitoring system using a potentiometer (18). The potentiometer and its wiper (19) are monitored by a microcomputer (66) which has stored in its memory (67) 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 a monotonocity function (Fig. 2).
