P-10 DOOR INTERLOCK FUNCTION

USING THE DOOR INTERLOCK FUNCTION
This section describes how the door interlock function should be used for the machine equipped
with a manual door and also for the machine equipped with an automatic door.
1.
Door interlock function for the machine equipped with a manual door
2.
Door interlock function for the machine equipped with an automatic door
The automatic door is optional. When the machine is equipped with the automatic door,
the door interlock function operates in different manner between the machine not
equipped with a robot (operation is assumed to be performed by an operator) and the
machine equipped with a robot (operation is assumed to be performed by the robot).
Refer to the manual dealing with the machine of the same type as installed to the
customer's shop.
Mori Seiki recommends the customer to use the machine with the door closed and the
door interlock function valid.
WARNING
If the door interlock function is "released", this constitutes a very
dangerous situation since the following operations are permitted, which
may lead to injuries.
1.
Even when the door is open, automatic operation with the single
block function valid (single block operation) is permitted. (MDI mode
operation)
2.
Even when the door is open, all operations are permitted in the
manual mode.
3.
If the door interlock function is "released" while the single block
function is valid, the door is unlocked permitting the door to be
opened even while the machine is operating, independent of the
selected mode or the operation presently carried out (automatic
operation, manual operation).
To ensure safety in operation, the customer is requested to promote
safety and not rely solely on the interlocks provided by the door interlock
function, e.g. by giving appropriate safety training to operators and
maintenance technicians, etc.
If the necessary operation requires work to be carried out with the door
open or the door to be opened while the machine is operating after
releasing the door interlock function, this work must be limited only to
that which is absolutely necessary and must be carried out very carefully.
NOTE
