Automatic Heights; Troubleshooting; Locking The 5.2 Transport Systemo - BMG Labtech PHERAstar FS Operating Manual

BMG LABTECH
4.8 Automatic Height Sensor
The PHERAstar FS measures the focusing in steps of 0.1 mm for both top and bottom reading modes. To
make the focus alignment (also known as Z-focus) as fast as possible, an initial plate height monitoring takes
place upon every plate-in command. For more information on the Z-focus see the PHERAstar FS quick
guide and the software manual.

5 Troubleshooting

5.1 Locking the Plate Carrier manually
Check that the plate carrier is really fixed by opening the plate carrier door with a fingernail and gently trying
to move the plate carrier in all directions (figure 31). It is locked if the plate carrier cannot be moved. If the
plate carrier can be moved, and hence is not locked, then either follow the described procedures again or
lock it manually:
1) Start with the transport pin in its upper position.
2) Then position the plate carrier with your right hand at the same time as you move the transport pin down
with your left hand. The goal is to position the plate carrier so the transport pin fits into the groove (figure
32). You may have to move the plate carrier around slightly (gently) until the transport pin fits into the hole
and then locks the plate carrier.
