Chapter 4: E2 Controller

The Service>Options>Group Setup screen allows you to select the workgroup duty assignment for the A/C unit. The duty must be assigned for each grouped A/C unit at its local display terminal.

Enter the number of days between rotating active units.

Enter the hour of day for unit rotation to occur.

The screen also displays a status message indicating which A/C unit you are accessing and which unit is currently the lead unit in the group.

Capacity Assist

Figure 4-86. Capacity Assist screen.

The first Service>Options>Capacity Assist screen allows you to enter the delay period for the unit to begin operating if it is in the capacity assist mode. Also each A/C unit in the group may be assigned local cut-in and cut-out setpoints for its capacity assist operation. The values entered are offsets, which are applied to the control setpoints.

Each unit in the group should be assigned incrementally increasing/decreasing offsets for cooling, humidifying, and dehumidifying so they will turn on one at a time only if the unit(s) currently operating are unable to satisfy the demand.

Capacity Assist #2

Figure 4-87. Capacity Assist #2 screen.

The second Service>Options>Capacity Assist screen allows you to adjust local capacity assist humidification and dehumidification setpoints.

Group Sensors

Figure 4-88. Group Sensors screen.

The lead controller polls the controllers from all the A/C units in the workgroup and calculates the averaged value of their temperature sensors and humidity sensors. It also determines the minimum (lowest) temperature sensor value and the lowest humidity sensor value in the A/C group and conversely, determines the maximum (highest) temperature sensor value and maximum humidity sensor value in the A/C group.

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.
