Troubleshooting Remote/Cluster Partner Missing Error

Answer

This Information Applies To: All Agilent LC systems.

Issue:

A cluster is partnership between modules. Most modules are linked to other modules automatically, without intervention from the user, but sometimes the cluster is configured manually.

Examples:
1. To work as a ‘one module’ unit, independent modules must be clustered (e.g.: Two G1361A prep pumps are clustered to make one gradient pump).
2. A valve pressure cluster between the 1290 Infinity pump and external valves allows for correct operating pressure.
3. A sampler being assigned a specific pump, especially in a two-pump system.

If the cluster is changed or the communication is lost, the resulting error may be Remote Partner Missing or Cluster Partner Missing and the device will switch to Not Ready status.

Steps to follow:

  1. First Check that all modules are powered on, and the CAN cables are connected.
  2. In general, forcing a cold start should resolve the remote partner missing error. Check this article on how to do it: Forced Cold Start Procedure. 
  3. For autosamplers: A sampler may need the pump re-assigned (e.g. after an exchange of the pump), which may be done within the instrument software in the Control menu. Right-click the module icon and select Control. From the drop-down menu under Pump connected to sampler, choose which pump is connected.
  4. Firmware Declustering is available in the Lab Advisor Software as an option in Service & Diagnostics (please see Figure 1). A cluster can be declustered to avoid a Not Ready condition and a Cluster partner missing error. 

 

 Tip  Note: Firmware declustering was added to the Basic version of Agilent Lab Advisor since revision B.02.12 so if your version doesn't show it, update it. Copy-paste the following link in your browser to download the latest available version of Lab Advisor: http://labadvisor.pl29.agilent.com/latest

During autoconfiguration, if the system detects that there are modules that can be clustered, a dialogue allows you to select the modules to include in the cluster via check boxes. Select the modules for the Column Compartment Cluster and the Pump/Valve Cluster separately.

To start the clustering, pick one of the available cluster option buttons (see Figure 2).
