ACQUITY APC CM-S and CM-30S configuration and column positioning control problem - WKB9456

Article number: 9456

SYMPTOMS

  • Unit faults with a Column error: "Multi mode column selection is out of range CM(x) CM(y)" Instrument method control of column positions: CM-S column set to "No Change" and CM-30S set to "Column 1".
    • Instrument method editing: Changed the CM-S to None, saved, and set up again. Failure continues to occur.
    Mismatch between the actual valve position and the valve position indicated in the Empower direct control panel.
    • The valve position in the direct control panel shows the "column 1" position, but the actual valve position is "waste" This issue occurred at module initialization, after turning on each module.
    The Column Manager (CM-30S) disappears from the console software Empower system configuration has both column manager devices present with status OK.

ENVIRONMENT

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

CAUSE

Power-cycling of the column manager devices in the incorrect order caused a valve mapping issue.

FIX or WORKAROUND

  1. Clear the non-volatile memory of each instrument to ensure proper valve mapping of the column configuration. Clearing non-volatile memory" is a service mode function for the device. You must enter service mode in order to clear the memory. Do this for both column manager modules, so that you restore factory defaults.
  2. Delete the system in Empower and the system component entries in DHCP Server Configuration.Power-down the system and reboot the Empower PC.
  3. Power-up the system. Power-cycle the column manager devices in the correct order according to the ACQUITY Advanced Polymer Chromatography System Guide.
  4. Power-cycle the secondary manager (CM-30S or Dual CM-S) first.
  5. Power-cycle the primary manager (CM-S with valves) second.
  6. Confirm that DHCP populates with appropriate IP addresses.

  7. Reconfigure the system. The CM-S (with valves) installed as the primary module is the first serial number added to the system configuration. Secondary modules (CM-30S or Dual CM-S) are added to the Empower system configuration second.

  8. Confirm in the console that the CM-S is configured as the primary. From the console system tree, select System. From the Configure menu, select Primary Column manager. All column managers will be listed. The primary column manager has a check mark next to it.

ADDITIONAL INFORMATION

Follow the installation guidelines for creating the system configuration as described in the ACQUITY APC System Guide.
