Hardware Symptoms
In case of a problem with the vacuum system or the electronic control the
micro vacuum degasser status lamp will be red. The micro vacuum
degasser will generate an error output on the remote lines. This will shut
down other system modules when connected via remote cable, see
“Installing the Micro Vacuum Degasser” on page 19. The vacuum degasser
itself is not able to generate any error messages in the Agilent 1260
Infinity system logbook. The following pages describe hardware symptoms
which help you to isolate the cause of a hardware failure.
All Lamps are Off
If all other modules in the system are on (power switch lamp is green)
and are recognized by the connected user interface (module parameters
can be set, module- specific screens appear, and so on), then do the
following to determine the problem with the micro vacuum degasser:
✔ Ensure the power cable is connected to the degasser, and the power
cable is connected to line power.
✔ Ensure the power switch on the front of the module is ON.
✔ Ensure the power fuses are OK.
The fuse holders are located on the rear panel of the micro vacuum
degasser and are part of the power socket. Check the fuses (see
“Exchanging the Fuses of the Power Inline Filter” on page 60), and
change if necessary:
✔ If the previous steps did not solve the problem, change the control
assembly (see “Exchanging the Degasser Control Assembly and the
Sensor Assembly” on page 76).
