10.7 Operation With the Door Open
If the external ambient dew point exceeds the XDF’s internal tempera-
ture, the iCOM control will flash a warning that condensation may
form inside the enclosure if a door is opened. The warning is an icon of
a door with an “X” on top of it. The word NO appears beside the icon.
If a warning is flashing, the XDF’s doors may be opened safely while
the unit is operating by following these steps:
1. From the default screen, press the Enter key (see Figure 28) to
access the user menu.
2. Press Enter a second time to select and highlight the Password line.
3. Use the Down arrow to scroll to the Setpoints icon.
4. Press the Enter key again to access the Setpoints submenu.
5. Press Enter again to highlight the first command line.
6. Using the Down arrow key to highlight the DOOR OP command line.
7. Hit the Enter key to highlight the setting adjustment.
8. Use the Up and Down arrow keys to change the status to YES.
9. Press Enter to accept the change.
10. Hit the ESC key four times to return to the default screen.
11. The iCOM control will begin reducing cooling until the XDF’s internal temperature is high
enough that condensation will not occur if the door is opened.
12. Once the internal temperature reaches this point, the “Door Open Wait Timer” starts counting
down.
The XDF may be opened without internal condensation when the
default screen removes the “X” from the door icon and the word OK
appears beside the icon.
The XDF will keep the temperature at the level required for opening the
door for two minutes. If a door is not opened within two minutes, the
XDF will return to the normal operating point.
If a door is opened, the XDF will remain in “Open Door Operation” sta-
tus until all doors are closed. After all doors are closed, a two-minute delay is initiated before the unit
returns to its normal operating setpoint. If a door is opened again within the two-minute delay, the
timer is reset and will restart when the door is closed.
