US Patent:

7804262, Sep 28, 2010
Filed:

May 15, 2006
Appl. No.:

12/299695
Inventors:

Don A. Schuster - Lindale TX, US
Zane Prince - Tyler TX, US
Assignee:

Carrier Corporation - Farmington CT
International Classification:

H02P 1/00
US Classification:

318283, 318260, 318560
Abstract:

An electronic apparatus externally detects open protector contacts inside of a compressor. The compressor includes a compressor motor having a run winding and a start winding. The compressor motor also includes internal protector contacts that open the electrical circuit to the “C” terminal in a protection condition. A compressor running indicator circuit is electrically connected between the “S” and the “R” terminals to indicate a compressor running condition. Also, a protection indicator circuit is electrically connected between the “C” and the “S” terminals to indicate a voltage present across the “C” and the “S” terminals. The protection indicator circuit is also coupled to the compressor running indicator circuit such that the protection indicator circuit is disabled when the compressor is running normally and the protection indicator is enabled and indicates when protector contacts open inside of the compressor.
