Article number: 9155

SYMPTOMS

  • "Multi mode column selection is out of range" error when controlling column positions in two devices

ENVIRONMENT

  • APC Single Zone Column Manager (CM-S)
  • APC 30cm Single Zone Column Manager (CM-30S)

CAUSE

If this alarm appears, you have selected one of the following invalid combinations in the two column manager devices:

  • Bypass and column number
  • None and None
  • Column number and column number

FIX or WORKAROUND

If “Column selection is out of range” alarm occurs:

  • "Bypass" is selected in one column manager and "Column number" or "No Change" in the other column manager.   
    • Resolution: Replace "Bypass" with None.
  • "Column number" or "No Change" is selected in both column managers.
    • Resolution: Select "None" in one of the column managers.

ADDITIONAL INFORMATION

Selecting "No Change" is equivalent to selecting a column, because No Change directs the system to use the current column.
