Starting up the unit
NOTICE
Connection IN / OUT closed
The FAM will be destroyed
►
Check to be sure that all of the locking fixtures at the inlet / outlet are
in "open" position each time before start-up.
After you have made all connections and completed the preparations for
commissioning, switch on the FAM at the main switch. For the lamp test, all
lamps light up briefly.
Then the FAM goes to malfunction "[H15] V-pump pressure"; the malfunction
light [S3] "Malfunction" blinks. This fault message results from the switch
position of the "Siguard" (electric circuit diagram = A5) in the control cabinet
and is eliminated by pressing the button [S1] "Start delay" or the button [S3]
"Malfunction".
The system now begins with the starting phase. The vacuum pump starts up,
the inlet valve opens, and the vacuum column is filled. When the vacuum
chamber is filled to filling level [02], the evacuation pump is started up and
the starting phase is finished. The purification operation runs. This is shown
by the lighting up of the operating status lamp "FAM operation (H4)".
Setting the vacuum pressure
Now regulate the vacuum pressure in the vacuum column with the throttle
valve underneath the vacuum pressure display, depending on the operating
viscosity.
