Fast Acting Safety Interlock
Many marking applications require a safety action to occur for each part that is marked. An example of
this action is a machine that lowers a shield over a part prior to marking, and then raises the shield to
advance the part as soon as the mark is complete. SYNRAD lasers are equipped with a Remote Interlock
feature that disables laser ring, typically when a safety switch on an access door or enclosure is opened.
However in marking applications where a safety interlock is frequently cycled, the Remote Interlock may
create an unacceptable delay. This delay occurs because closing the interlock (and cycling the Keyswitch,
or remote keyswitch, on Keyswitch-equipped lasers) invokes a built-in ve-second delay prior to lasing.
