5-1
Lock and Unlock of Manual Door
For the machine equipped with the manual door, the door is locked and cannot be opened when
the door is closed with the indicator above the DOOR UNLOCK switch not lit. To open the door,
unlock the door by using the DOOR UNLOCK switch.
1.
The machine recognizes that the door is closed when the door is closed and locked.
Even if the door is closed, the machine does not recognize it closed unless it is
locked. Such status is recognized as the door is open.
In the manuals published by Mori Seiki, the expression "door is closed" means that
the door is closed and locked.
2.
When power is turned on, the NC checks the functions of the door lock device and
those of the contactor for spindle/axis drive motors.
After turning on the power, open the door once and close it again. The machine
does not get ready unless the door is opened and closed after turning on power.
WARNING
If the door interlock function is "released" while the single block function
is valid, it constitutes very danger situation since the door is unlocked
permitting the door to be opened even while the machine is operating,
independent of the DOOR UNLOCK switch position (lock or unlock) or the
selected mode. If the necessary operation requires work to be carried out
with the door open while the machine is operating, this work must be
limited only to that which is absolutely necessary and must be carried out
very carefully.
Work which is carried out with the door open while the machine is
operating will cause injuries due to the operator being entangled in the
rotating parts of the machine, crushed by its moving parts, being struck by
a workpiece or chuck jaws that have flown out of the machine, or being
splashed by chips and coolant.
