* How Does The Copland Scroll Compressor Work
Unlike reciprocating technology with many moving parts, the Copeland scroll compressor has one scroll or spiral orbiting in path defined by a matching fixed scroll. The fixed scroll is attached to the compressor body. The orbiting scroll is couple to the crankshaft in orbit rather then rotated. The orbiting motion creates a series of gas pockets traveling between the two scrolls. On the outer portion of the scroll the pocket draw in gas, then move it to center of the scroll where it
•s discharged. As the gas moves in the increasing smaller inner pocket, the temperature and pressure increase to the desired discharged pressure.

* IMPORTANT!!! - PLEASE NOTE: IDENTIFYING COMPRESSOR FAILURES
Most compressors fail due to system malfunctions, which must be corrected to prevent repeat failures. After a compressor fails, field examination of the failed compressor often will reveal symptoms of system problems. Proper corrections will help eliminate future failures.
* SINGLE PHASE BURN
Two phases of a three-phase motor overheated or burned as a result of the contactor opening only one of its contacts.
Correction:
(1) Replace contactors with properly sized contactors.
(2) Check for proper motor protection.
* HALF WINDING SINGLE PHASE BURN
In a two contactor application, two phases of one half of a three phase motor overheated or burned as a result of one contactor opening only one contact.
Correction:
(1) Replace contactors with properly sized contactors.
* HALF WINDING BURN
Half of all phases on a two contactor three phase motor are overheated or burned due to only one contactor opening.
Correction:
(1) Replace contactors with properly sized contactors.
(2) Check for feed back circuit holding one contactor closed.
* PRIMARY SINGLE PHASE BURN
Only one phase of a three phase motor is overheated or burned as the result of opening one phase on the primary side a delta to wye transformer.
Correction:
(1) Check primary side of a delta to wye main power transformer.
* START WINDING BURN
The start winding only of a single-phase motor is uniformly overheated or burned.
Correction:
(1) Check for proper wiring of compressor.
(2) Check starting capacitor and/or starting relay.
(3) Correct compressor overloading.
* SPOT BURN
A localized burn within a winding, between windings, or from windings to ground. If not the result of mechanical problems, check for spikes or surges of high current flow.
* SHORTED TERMINALS
A break down of the insulation between terminals and compressor body generally the result of over torquing terminals.
