Starting up the unit
NOTICE
Connection IN / OUT closed
FAM goes into error mode
►
Check to be sure that all of the locking fixtures at the inlet/outlet are in
"open" position each time during 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 error message results from the switch
setting of the "Siguard“ (electrical circuit = A5) in the switch cabinet and is
cancelled by pressing the key [S1] "Feed line" or the key [S3] "Reset".
Now the system starts with the starting phase after pressing the key [S1].
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. Maintenance mode
runs. This is shown by the lighting up of operating status lamp "FAM
operation (H4)".
Setting the vacuum pressure
Now regulate the vacuum pressure in the vacuum column with the needle
valve underneath the vacuum pressure display, depending on the operating
viscosity.
