3 Functional process
3.1 Home position (sensor #1)
Door Seal Door Loop Connector Motor
The door is open and can be closed
without operators having to exert much
force.
3.2 Door is latched (sensor #2, sensor #1 remains active)
The door latches onto the door loop but
need not be closed completely. The door
locks preliminarily and prevents the door
from opening.
A command of the machine control unit
could still unlock the door. To do so, run
the motor
forward
(
3.2 Motor actuation)
to sensor #6. Then go to
section 4.6.
3.3 Door moves into the seal (sensor #3)
Output "close door" command.
The motor drives the door
backward
into
the seal (400 N) up to sensor #3.
A spring actuator compensates for any
wear on the door seal (retaining a constant
sealing pressure).
Seal or door loop defective (sensor #4)
When you close the door and the motor fails to stop at sensor #3 but runs on to sensor #4, there
is a defect either in the seal (e.g. wear) or in the door loop.
If so, the drive must stop, and the fault has to be removed immediately.
