Operation

10.0OPERATION

The XDF is intended for operation with its doors closed and latched. This increases efficiency and keeps out dust and humidity.

With the doors closed, the XDF will achieve full capacity in ambient conditions up to 95°F (35°C) and 40 percent relative humidity. The XDF’s cooling efficiency is reduced if it is operated in higher ambi- ent temperatures and humidity. The reduction varies according to the heat load from the installed equipment and the external temperature and humidity.

The XDF may be operated for short periods with its doors open. Refer to Figure 10.7 - Operation With the Door Open.

10.1Environmental Control

The XDF’s cooling functions are controlled by Liebert’s iCOM control module. This section describes the iCOM’s basic functions, such as start-up and navigation. For further details on setting up and using your iCOM, refer to 10.2 - iCOM Components and Functions and 10.3 - Navigating Through the iCOM Display or call 800-543-2778.

NOTE

The iCOM installed on the XDF is programmed for single-unit control. It does not have the capability of communicating with other iCOM units. Disregard portions of the iCOM manual that refer to multiple unit operations.

The menu-driven iCOM display is used for programming each cooling function. The screen shows the status of the conditioned space, setpoints, alarm status and settings, event histories and the current time.

Remote Communications—Building Management Systems, Liebert SiteScan

The iCOM controller on the XDF may be remotely accessed with Liebert’s SiteScan systems, Modbus or with SNMP.

Each XDF is equipped with Intellislot bays for use with optional communication cards:

•OpenComms 485—enables the XDF to communicate via Modbus or BACnet protocols to Liebert’s SiteScan or third-party building management systems

•OpenComms Web—enables the XDF to communicate via SNMP
