The line graph shows the selected sensor’s readings (black) chronologically from left to right—the most current reading is on the far right—as well as Warning (yellow) and Critical (red) limits.

•Use the All or Limit button to change the scale of the y-axis on the graph, as follows:

•Click Limit to use the High and Low Critical values to determine the upper and lower bound- aries of the graph. In the example above, the y-axis extends from 10% to 90%, which are the Low Critical and High Critical values for Humidity Sensor 2.

•Click All to include the sensor data readings to determine the upper and lower limits of the graph. In the example above, if a data reading were 95%, the y-axis scale would extend from 10% to 95% to include that reading. (If all sensor data readings fall within the High and Low Critical limits, the All and Limit buttons display the same scale extending from the Low Crit- ical value to the High Critical value.)

• Use click-and-drag to zoom in or out:

ZOOM IN FEATURE - Humidity sensor example

• To zoom in on an area of the graph, click

 

and drag the mouse downward to draw a

 

box around the area. The maximum zoom

 

level shows 10 units on the y-axis (degrees

 

or percentage points, for example) and six

 

data samples on the x-axis.

 

• To zoom out, click and drag the mouse in an

 

upward direction. (Or click on All or Limit

 

to restore the graph to full view.)

 

• Click the Refresh button to update the graph

 

with the most recent sensor reading. The sensor

 

is sampled at regular intervals. See 5.7.3 - Data

 

Presentation to change this interval.

 

• Click the Close button to exit the Sensor

 

Graphs window and return to the Sensor Data

 

window.

EM specifications

The Liebert EM is a state-of-the-art, modular and scalable cooling solution designed to meet the needs of today's data centers and IT environments. This innovative unit offers unmatched precision and flexibility, making it ideal for facilities that require meticulous temperature control and energy efficiency.

One of the main features of the Liebert EM is its modular design, allowing for easy expansion and customization based on the specific requirements of a facility. This scalability ensures that organizations can efficiently adapt to changing cooling demands without the need for significant infrastructure changes. The system can be configured in various capacities, making it suitable for spaces of different sizes and cooling needs.

Incorporating advanced technologies, the Liebert EM utilizes inverter-driven compressors, allowing for variable refrigeration capacity. This feature optimizes energy consumption, reducing operational costs while maintaining precise temperature control. The unit is designed with built-in smart controls that enable real-time monitoring and adjustments, ensuring enhanced performance and efficiency across the entire cooling system.

The Liebert EM also comes equipped with EC (Electronically Commutated) fans, which contribute to its energy efficiency by adjusting their speed according to the cooling load. This not only ensures adequate airflow but also minimizes energy waste, leading to lower overall operating costs.

Furthermore, the system features intelligent connectivity options that facilitate integration with existing building management systems. This capability allows for centralized monitoring and control, empowering facility managers to maintain optimal conditions and respond quickly to any fluctuations in temperature or humidity.

Safety and reliability are also paramount in the design of the Liebert EM. The unit includes comprehensive backup systems and redundancy features to ensure continuous operation even in the event of a component failure. This reliability is crucial for critical applications where downtime can result in significant losses.

In summary, the Liebert EM stands out as a versatile and high-performance cooling solution, equipped with advanced technologies that offer scalability, energy efficiency, and precise temperature control. Its modular design, coupled with intelligent control options, makes it an essential component for modern data centers looking to optimize their cooling infrastructure while ensuring reliability and reducing operational costs.
