Alarm error codes for Carrier ML-2i and ML-3 controllers

Decoding error codes Thermo King SL 200

An experienced driver probably knows the most common error codes for the Termoking SL200e and other refrigerators of this brand. Those who have just started working on such a refrigerator can use a table that lists all possible errors in the Termoking SL200e and their codes. Knowing the decoding of the code, you can quickly find out the reason for the malfunction of the refrigerator and make the right decision.

The microprocessors equipped in different models of the Termoking line may differ. The table displays all possible emergency codes, and in the Termoking SL200, for example, the error codes may not contain everything that is listed in the table, just like in any other modification of the refrigerator. The table, as a rule, indicates for which units and control units it can be applied.

What to do if Termoking SL200e gives an error

It is better for novice drivers to have a table with them where error codes for Thermo King SL200 or other modifications are given not only with an explanation, but also with brief instructions on what to do in each individual case.

Errors of the Termoking SL200e, like other refrigerators, can be divided into several categories of complexity:

Errors that are resolved automatically. When the controller issues such an error, the driver does not need to take any action. But the error must be recorded and reported to the technician who performs maintenance of the unit.
Errors of Termoking SL200, etc., which do not lead to shutdown of the unit. If such a malfunction occurs, you can complete the delivery of the goods and then contact the service center. The driver can fix some problems himself.
When the Termoking SL200e issues an error code, which is accompanied by the unit shutting down, repairs are required immediately. In this case, you will have to call the service department to the place where the unit is stopped. Knowing the Termoking SL200 error code, you can tell it to the service specialists so that when they go for repairs, they can take the necessary spare parts with them.

Thus, error codes for Thermo King SL200 and other modifications of the unit will help you make the only right decision in any situation.

Frame

Refrigerated container bodies come in different sizes: 10 feet, 20 feet, 40 feet and 45 feet. You can read about the features of these sizes in our article Dimensions and dimensions of a refrigerated container

It is important to understand that the structure of the hull can vary greatly, based on the dimensions of the refrigerated container, manufacturer and year of manufacture.

What is the body made of?

For example, let's take the most popular size - 40 feet. The container body consists of a supporting frame (vertical and horizontal corner beams) at the corners of which there are fittings (eyelets for loading and unloading the container) and transverse floor beams.

Walls

The wall of a refrigerated container is a sandwich made of polyurethane foam panels (100 mm thick) with an outer covering of stainless steel 2-3 mm thick (since 2000) or “riveted” aluminum (before 2000). The internal coating also consists of stainless steel (shiny walls) or aluminum (white walls), 1 mm thick.

Internal borders. They are also called reinforced sides. In some buildings, refrigerated containers were made to order from the shipping line. They are designed to avoid “swelling” of the housing walls. This occurs when a loaded reefer container is placed on the ground. As a result of the pressure of the load, the body inflates. If you use the refrigerator as a stationary refrigerator and do not move it loaded, then you will not see any special advantages of this modification.

A metal sheet 0.6 cm thick is installed on the cross beams of the supporting frame. Next comes 10 cm thick foam. 3 cm plywood. And a durable T-shaped aluminum profile that can easily withstand a regularly operating loader with goods.

In a 45ft refrigerated container the floor is flat.

Ceiling

The ceiling is the same sandwich, 15 cm thick. 35-grade foam is used. The inner surface is aluminum (white color) or stainless steel (shiny ceiling). The outside is made of stainless steel.

Doors

The doors are made of the same multi-layer panels as the walls and ceiling of the building. The doors swing open to an angle of 270°, which ensures convenient loading and unloading of products. The thickness of the sandwich is 10 cm. 50th foam is used. The inner side is made of stainless steel. The outer side is often made of aluminum. Less commonly made of stainless steel. There is rubber sealing at the end of the doors. Also, the doors are equipped with special latches that allow the cargo compartment of the refrigerator to be hermetically sealed.

Operating principle of a refrigerated container

The refrigerated container system is closed and sealed. It contains freon, a cooling gas. In this case, R-134a.

Through the suction line, this gas enters the compressor. The compressor pumps this gas and then it enters the condenser, where it is brought to a boil and becomes colder. From the condenser the gas enters the receiver. The receiver plays the role of an expansion tank. This is where the excess pressure is released. Next, the gas passes through the dryer filter, i.e. the gas is dried and supplied through the expansion valve to the evaporator. Next, the evaporator fans take the cold away from the evaporator, blowing cold air from top to bottom. The air passes through the container, circulates, returns back to the top and, thus, becomes colder with each circle. Due to this, the temperature decreases.

Refrigeration unit

The refrigeration unit of a refrigerated container is a “cassette” block in which electronics and components are installed.

The composition and characteristics of electronics can vary greatly depending on the brand of the container (Carrier Transcold, Daikin, ThermoKing, Sabroe, Seacold, Mitsubishi). If you want to understand their differences in detail, read the article https://ref-konteyner.ru/blog/kakie-byvayut-brendy-refkonteinerov

The most popular brands are Carrier and Thermo King.

Despite the fact that there are differences between manufacturers, they are also very significant between the models of these brands. We described all the details in this article https://ref-konteyner.ru/blog/modelnyi-ryad-refkonteinerov-carrier

In the future, in this article, we will provide information using the example of the Carrier brand and the most popular model in the world, ThinLine, which has been consistently produced for more than 30 years.

The main elements of a refrigerated container installation:

Compressor
Capacitor
Condenser fan
Evaporator
2 evaporator fans
Controller with multiple starters
Receiver
