This Information Applies To: All Agilent LC modules (except hosted modules).
When a module does not initialize correctly or it is not recognized by the software, it is recommended to call our Remote Support Representatives to troubleshoot the issue. You may be asked to follow the cold start procedure to recover the correct functionality of the module. A forced cold start can be used to bring the module into a defined mode with default parameter settings.
Save your methods and data before executing a forced cold start. A forced cold start erases all methods and data stored in the nonvolatile memory of the module, i.e a non saved state.
Exceptions are calibration settings, diagnosis, and repair logbooks, which will not, be erased.
Do not use a pencil or a fragile tool to move the switches to avoid breaking it inside the module. We recommend you to use a screwdriver or a pen.
Steps to follow:
Figure 1. Location of Configuration Switch (CONFIG) and different type of Switches of HPLC modules.
|2 switches||1 0|
|6 switches||1 0 0 0 0 1|
|8 switches||1 1 0 0 0 0 0 1|
The instrument will always revert to the default state after a cold start. It is especially important for plate types and the metering head size in autosamplers. For example, the 900 µL analytical head upgrade will not be recognized. It must be set again in the software (the same as during initial installation). The sampler will default to the standard 100 µL head.
