Notes
The position of the guard door,
which is pneumatically activated,
can be reported reliably
(SAMH-S) and directly via the
drive. Additional sensing per
EN 1088 is not necessary.
The guard door is opened by
a cylinder.
If the door is open, the cylinder
is not in the normal position.
This is detected by the safe
position encoders; the system
remains at rest.
Switches are mechanically
connected, are protected against
manipulation and securely
mounted.
