Chapter 4: E2 Controller

4.5.2.10 EHGB Status

Displays the current operating position of the electronic hot gas bypass valve. The current suction temperature appears below. The bar gauge next to the valve icon provides a visual representation of the output signal controlling the valve position.

4.5.2.11 Fan Status

The Fan Status screen displays symbols indicating the operating status of the upper, middle, and lower fans. The symbols are animated when the fans are

running. If a fan is not running, the symbol will appear instead. The value of the proportional output signal (0 to 100%) that controls each fan appears in the field to the right of each symbol. The animated icons are linked together indicating the three fans are being controlled to the same fan speed setting (default). The controller also displays the temperature value for the sensor from each fan zone. The fans may be linked or unlinked in any combination for individual zone temperature control (see Section 4.5.4.1).

The message “Var from Avg” or “Temp Prop” appears indicating the speed control configuration (see Section 4.4.4.1). The message in the field is replaced with “Dehum” when the system is in the dehumidification mode. In the dehumidification mode, the animated icons are always linked together indicating that the three fans are being controlled to the same (dehumidification) fan speed setting.

4.5.2.12 Group Information Menu Screens

The Group Information menu screens only appear if the controller is set up to operate multiple A/C unit work groups. See Section 4.6.2.8 for a more detailed description of these screens.

4.5.2.13 Software Version/Date

Displays the type of A/C system the controller is configured for (W/G, AR), and the Black Box software version and its release date.

CRDX-W-FS-12KW, Black Box Cold Row DX, CRDX-W-FS-24KW, CRDX-A-FS-24KW, CRDX-A-FS-12KW specifications

The Black Box CRDX series consists of high-performance cooling solutions designed to maintain optimal temperature conditions in data centers and server rooms. Key models in this series include the CRDX-W-FS-12KW, CRDX-W-FS-24KW, CRDX-G-FS-12KW, and CRDX-A-FS-24KW. These units are engineered to provide efficient cooling while addressing the rising demands of modern IT infrastructure.

One of the standout features of the CRDX series is its cold row design. This configuration enables targeted cooling delivery directly to the equipment, enhancing efficiency and reducing energy consumption. The airflow management in these models ensures that cooled air is directed where it is needed most, minimizing hotspots and maximizing cooling performance.

Both the CRDX-W-FS-12KW and CRDX-W-FS-24KW models utilize advanced refrigerant-based cooling technology. These units are equipped with electronically commutated (EC) fans, which are highly efficient and quieter than traditional fan technologies. This innovation not only lowers operational costs but also creates a more comfortable environment within the data center.

The CRDX-G-FS-12KW model stands out for its hybrid capabilities, offering both chilled water and direct expansion cooling options. This versatility allows facility managers to choose the best cooling approach based on their specific requirements and current infrastructure. The hybrid system can optimize energy consumption and enhance cooling efficiency, contributing to lower operating costs.

Another noteworthy feature across these models is their intelligent controls and monitoring capabilities. Equipped with sophisticated sensors and control systems, operators can gain real-time insights into temperature fluctuations, humidity levels, and unit performance. This data aids in proactive maintenance and ensures that cooling systems are operating at peak efficiency.

The CRDX-A-FS-24KW, on the other hand, is designed with a focus on adaptability and scalability. This model can be integrated easily into existing network setups, making it an excellent choice for facilities that anticipate future growth or need to adapt to changing cooling demands.

Overall, the Black Box CRDX series exemplifies the latest advancements in cooling technology, offering innovative features designed to support high-density computing environments. With their efficient cooling capabilities, intelligent controls, and flexible design options, these models provide reliable solutions for data centers looking to enhance their cooling systems while reducing operating costs.
