4. ADJUSTMENT

4-1 COMPRESSOR

4-1-1 Role

The compressor intakes low temperature and low pressure gas from the evaporator of the refrigerator and compresses this gas to high-temperature and high-pressure gas. It then delivers the gas to the condenser.

4-1-2 Composition

The compressor includes overload protection. The PTC starter and OLP (overload protector) are attached to the outside of the compressor. Since the compressor is manufactured to tolerances of 1 micron and is hermetically sealed in a dust and moisture-free environment, use extreme caution when repairing it.

4-1-3 Note for usage

(1) Be careful not to allow over-voltage and over-current. (2) If compressor is dropped or handled carelessly, poor

operation and noise may result.

(3) Use proper electric components appropriate to the

particular compressor in your product.

(4) Keep compressor dry.

If the compressor gets wet (in the rain or a damp environment) and rust forms in the pin of the Hermetic Terminal, poor operation and contact may result. If the hermetic connector rusts out or fails, refrigerant and oil will be expelled into the contact area, probably resulting in smoke and fire.

(5) When replacing the compressor, be careful that dust,

humidity, and soldering flux don’t contaminate the inside of the compressor. Contamination in the cylinder may cause noise, improper operation or even cause it to lock up.

4-2 TSD STARTER

4-2-3

-Applied circuit diagram

● Starting method for the motor

4-2-4

ELECTRICAL AND DIMENSION DIAGRAM

ELECTRICAL CONNECTION DIAGRAM

TSD

START

MAIN

Ð The TSD must not be applied to refrigeration systems with

defrosting electrical resistance or any other component in parallel to the thermostat. Systems with this configuration can maintain a residual voltage over the compressor when the thermostat is opened, obstructing the proper functioning of the TSD. It is vital f or the TSD circuit and compressor t o remain completely de-energized after opening the thermostat.

Ð Use of the fixing clamp is essential, as this prevents

disconnection or bad TSD contact in relation to the compressor as well as to running capacitor in relation to the TSD. The ones that assemble it have to guarantee a perfect connection between the parts. Bad contacts and sparking can burn out the electronic circuit.

Ð The electronic circuit was designed taking the mandatory

use of the running capacitor into consideration. The 115V version is rect angular box, assembling directly onto the TSD body .

Ð The plastic box was projected to offer protection against

contamination and mechanical shock normally present in refrigeration system production lines.

Ð The TSD's internal components may undergo degradation

when in contact with chemical elements such as CI

,H2S,

,SOX,NOX. Some plastic isolation of cables may release chemical elements when submitted to high temperature conditions. Thus, check if the isolation of the cables used on the terminal board are in accordance with this recommendation.

The TSD was designed for the operation with a run capacitor and Embraco domestic compressor; any other application must be previously evaluated by EmbracoÕs technical team.

Embraco reserves the right to check the customer's handling of the manufacturing / assembly process, indicating possible adjustments should any be required.

After replacement, the compressor and itÕs accessories must have proper processing, and the components must be recycled according to the material group (ferrous, non-ferrous, polymers, oils, ...) directives. These recomendations are intended to minimize the adverse impacts that may be caused to the environment.

4-3 OLP (OVERLOAD PROTECTOR)

4-3-1 Definition of OLP

(1) OLP (OVERLOAD PROTECTOR) is attached to the

Compressor and protects the Motor by opening the circuit to the Motor if the temperature rises and activating the bimetal spring in the OLP.

(2) When high current flows to the Compressor motor, the

Bimetal works by heating the heater inside the OLP, and the OLP protects the Motor by cutting off the current flowing to the Compressor Motor.

4-3-2 Role of the OLP

(1) The OLP is attached to the Sealed Compressor used

for the Refrigerator. It prevents the Motor Coil from being started in the Compressor.

(2) For normal operation of the OLP, do not turn the Adjust

Screw of the OLP in any way.
