7.5 Manually resetting the blank
changer to default position
Cutting injuries when
CAUTION
touching a rotating tool
If a power failure or a machine malfunction occurs
during machining, the spindle including the inserted
tool keeps rotating. If you touch the rotating tool, you
will suffer from cutting injuries.
Wait until the spindle has stopped rotating before
performing an emergency opening.
In some cases (e. g. when a power failure occurs) the
blank changer may not be able to move back into
default position. This will produce an emergency stop
signal when the machine is started and the machine
will not reference.
In this case a manual reset of the blank changer to
default position is required.
1. Open the working chamber door. If necessary, per-
form an emergency opening of the working cham-
ber door.
