The end switches are wired in series (from cover clamp 1 -> 4). If one

end switch is not adjusted the input is missing in the software.

4.5.1 Working principle

Cover locking mechanism consists of locking clamp (c-hook), which is

pivoted on an eccentric shaft. Attached to this eccentric shaft there are

two locking levers.

Once locking clamp is in lock position, eccentric shaft is twisted by

applying force to the locking levers. This moves the pivot point further

more down and pulls the claps respectively the cover down by a certain

stroke.

Locking levers are pushed over the dead center this prevents clamp to

pulled open under load. Stroke can be adjusted by tilt of locking levers.

Setscrews can adjust tilt of the locking levers. Ball thrust screws on top

of the c-hook adjust pre-load.

Pneumatic cylinders initiate movements.

We are talking about locking cylinder - moves locking clamp (c-hook)

from or towards the cover. The clamping cylinders apply the torque via

the locking levers to the eccentric shaft.

Proximity switches indicating covers locked/unlocked and cover

clamped/unclamped monitor each movement
