Emerson Liebert iCOM Manual De Usuario

The Liebert iCOM allows an external sensor or analog device to be connected, scaled and viewed on the 
Liebert iCOM large display. These external devices require optional analog input connections that can be 
installed on new units at the factory or added to existing units in the field. The option provides the electrical 
connection from the Liebert iCOM control board to the required factory-supplied plug, harness and terminal 
strip. For parts, contact Liebert Services at (800) 800-543-2778. If a unit is equipped with this option, then a 
0-10VDC, 0-5VDC, 4-20mA, or a device such as a sensor or a damper can be connected to terminals 41 and 42, 
43 and 44, 45 and 46 or 47 and 48. See Table 13 for analog input availability.

Follow the settings in Figure 62 and Table 14 to set the input type based on the sensor output used. 

The default analog input is 0-5VDC. Only properly trained and qualified service technicians should 

change the analog input type.
