Emerson Liebert iCOM Manual De Usuario

The Liebert Optimized Aisle Control requires:

• A temperature/humidity sensor in the cold aisle and connected to the Liebert iCOM via CANbus. 

This can be done by:

• Moving the return temperature sensor from the cooling unit to the cold aisle with a longer 

CANbus cable

—OR BY—

• Obtaining a remote temperature sensor and addressing it to operate as the return 

temperature sensor.

• An additional supply temperature sensor placed under the raised floor.

Each 2T sensor has two wires leaving the housing with temperature sensors on the end of each wire; 

see Figure 68.

To install the Optimized Aisle Control 2T Sensor Array:
1. Set the DIP switch settings for the 2T sensors.
2. Terminate the final sensor on the CANbus link.
3. Install the 2T sensors on racks to be monitored.
4. Install the CANbus cable between 2T sensors.
5. Install the CANbus cable at the unit.
