- Check work area door (with electr. drive) and window pane
Orientation
Inspection and maintenance of the work area door includes several steps:
- Inspection of the window pane for damage.
- Checking the safety label on the window pane (replacement interval 8 years).
- Checking/adjusting or replacing, if necessary, the wipers.
- Check the work area door for smooth opening/closing.
- Check functions of the work area door – ( follow manufacturer's
documentation from Langer & Laumann ).
The window pane consists of three panes. The inner pane made of tempered glass,
the central pane made of polycarbonate, and the outer pane also made of
polycarbonate. The inner pane is relatively resistant. It can be cleaned with any
commercially available cleaning agents. Only the center pane is essential for the
impact resistance of the window pane.
The polycarbonate panes are subject to natural aging and therefore must be
subjected to regular visual inspection. Through contact with cooling lubricant, the
aging process is accelerated even further.
If the window pane is damaged, it must be replaced. This is
necessary regardless of the extent of damage. Even with minimal
damage, the impact resistance of the pane can no longer be
guaranteed.
Heavily soiled or damaged wipers may cause damage to the inner pane. Moreover,
it may be possible that the work area door can be moved only with considerable
effort due to heavy soiling or chip deposits in the wipers.
Regularly check and clean the guide rails of the work area door.
Check function of the automatic work area door with electric drive (option like open/
close) with different speeds with or without obstacle detection check.
Requirement
The automatic work area door can be tested only when the machine
is switched on and fully functional.
Be sure that the wipers have been checked before testing the
automatic work area door. Be sure to remove any chip nests and
make sure that the wipers have been cleaned and attached to the
plates.
Procedure
1. Check window pane for damage.
