The CM-S221 safety switches can approach each other from
most angles.
When the switch is closed the targets on the printed face of
the switch must be aligned.
Mount the switch on to the machine frame and the actuator on
to the opening edge of the door. Always try to mount the
switch on non-ferrous material.
Ferrous materials may reduce the switching distance.
Use the tamper proof screws.
Do not use the safety switch as a door stop. Leave a minimum
of 50 mm between any adjacent switches.
EN 1088
Provides some mounting suggestions, see example opposite.
When fixing the safety switch to a sliding door (A), ensure that
when the door is opened (B) it is not
easily accessible, helping prevent the system being
overridden.
All contacts should be fused externally
