Hello, could you help me, my GC Agilent 6890N suffered from a high voltage in the electric line and it turned off while performing a run.

Later when I turned it on again it showed me these information on its screen.

The firts screen

POWER ON INFO

Restart after power
interruption has
completed



Image open in separate window

The second screen

POWER RECOVERY INFO

OVEN TEMP ON forces oven on. STOP ends
all recovery phases


Image open in separate window

I appreciate any information that allows me to correct this failure. Thank you very much in advance.

You just have to manually turn on all the heated zones and detectors by selecting each one and pressing ON on the keypad.

The message is more cryptic than it really should be.

Yes, but the keyboard is locked and the computer does not know the GC. thanks.
I turn off the GC and then turn it on again, this cycle of messages is repeated on the screen and it does not allow me to do anything else because the keyboard is locked

Have you also restarted the computer for the data system? Sometimes it can lock the screen on the GC.

If the keyboard is locked then switch on the GC without computer.
If you now can press Options on GC keyboard then you will find Keyboard and Display and further an item to set Keyboard locked or unlocked.
Give it a try.

hi james, yes, the computer has been rebooted several times, but chemstation software doesn't recognize the GC, thanks james, but the problem continues.

I hate to say it, but sounds like maybe a board has been damaged since it will not get past the start up sequence.

hello: dblux_ and James, the GC is blocked, it does not respond either by its own keyboard or by the computer, it is possible that some physical damage has occurred in the oven and because of that the equipment does not start, the resistance of the heating or the chip on the electronic board that controls the heating or perhaps in the fan motor, could this be possible?

Thank you for your recommendations, I really appreciate your advice
