Currently I'm trying to get a Waters Alliance HT machine back online after it has not been used for over a year. The system was working as intended before this. The system consists of a 2795 separation module, a column heater, a 2996 photodiode array detector and a 2487 dual wavelength absorbance detector, and the entire system is controlled by Empower 2 software.
The separation module and column heater are working. The dual wavelength detector was displaying a critical error, but after a battery change and a manual recalibration, it powered on as normal again.
However, when I try to load a method involving the dual wavelength detector to the machine with Empower 2, I receive a system failure error. The seperation module is fine; when the software tells the separation module to initiate a new method, it sets the correct parameters and starts the flow. The PDA detector connected to the same system, is also being controlled as it should (i.e., I am able to monitor the baseline from the software with a method involving the PDA detector). But the dual wavelength detector cannot be changed to the correct wavelength I want to measure via the software. I can do it manually, but then the system still fails to initiate the method in the detector leading to the system not displaying anything (e.g. baseline monitoring), even though flow to the detector is fine. In the software system configure screen, it shows the dual wavelength detector as being online and all the cables are connected properly. The dual wavelength detector is set for measuring single wavelengths and the IEEE-address is at the default setting of 4.
I have tried:
- full reboot of computers, equipment and software
- taking the PDA detector offline
- connecting the dual wavelength detector with a different LACE cable that I know works
But so far nothing has got the system working and I am running out of ideas.
There is no one in the department that really knows how this machine works so any help you can give me is much appreciated!
Sincerely,
Dyarte
