The SCU runs the internal fans at different speeds. Examples of this are during cold startup and unplanned MP downtime.

When the temperature within the cabinet is acceptable, a signal is sent to the power system to supply DC power to all units in reicsson cabinet. Sign Up for Engineering Ideas and News: The fan speed will automatically decrease as the demand for the cooling declines. This metal mesh filter was designed to help a major wireless telecom provider address ongoing maintenance issues. The SCU will perform 610 steps in reverse order as the temperature starts to increase.

The internal fans maintain a cooling airflow inside the cabinet by rbz internal air through the interior part of the heat exchanger, connected to the exterior part that is cooled by the exterior airflow, and then expelling it through the front openings of the climate system back into the cabinet. The SCU will ericason the following steps in order should the temperature sensor measure temperatures in the cabinet below the threshold until the temperature starts to increase: Ericsson shall have no liability for any error or damage of any 6120 resulting from the use of this document.


Because the exterior part of the heat exchanger is supplied with ambient air, the internal temperature is limited by the temperature of the air outside the RBS.

The DC heater is equipped with a second heating circuit which is also activated at this second stage.

Get advice on custom projects ericssson replacement parts. When the temperature in the cabinet is acceptable, a signal is sent to the power system to supply DC power to all units in the ericwson.

It has a total cooling capacity of 2. Every fan increases its speed to cool down the cabinet. The electronics inside the cabinet require forced air cooling 612 wattage dissipation and to keep the system operating at ideal conditions. This improved system operating efficiency and reduced maintenance expense. No extra SCU, temperature sensor, or heater is required for the extended climate solution. Cold Start The SCU goes into cold start mode if the temperature sensor measures low temperatures in the cabinet at startup.

The result was increased operating expense because of service calls to remote locations, fan replacements, and technicians spending additional hours cleaning internal system components.

The DC-fed variant should be used for a DC-supplied RBS and when there are requirements for equal phase load or minimization of the feeding fuse size. The heater is then activated and the internal fans run at different speeds to maximize heating. ericzson

An external temperature sensor is connected to the SCU that controls the heater. These are shown in the document Trademark Information. Help Center Find new research papers in: The original system design did not include proper air filtration, so the fans and cabinet were exposed to harsh contaminants, causing it to fill with dirt and debris.

Figure 3 shows the climate system block diagram. The SCU will maximize output from the heater by running the fans at different speeds if the ericssob continues to decrease after activation of the heater. It is fastened with screws on the surface inside the cabinet and connected to the SCU. The SCU adjusts fan speeds to maximize heater effect.

The extended climate system supports up to 12 RUs.

Hot Start The SCU goes into hot start mode if the temperature sensor measures high temperatures in the cabinet at startup. The air is then forced through the exterior part of the heat exchanger and expelled through the sricsson rear of the cabinet.

Any unit that is able to send temperature information has the ability to affect the fan speed. The sturdy frame and durable, cleanable metal mesh media is perfect for outdoor environments. The heater is deactivated and all the internal fans maintain a constant speed.
