SAFETY FUNCTION
PHYSICAL INTERFACE
SF.1: Enable
no laser emission if “EXT_ENABLE_A or
“EXT_ENABLE_B” signals are disabled,
where “disabled” means contacts open
SF.2: Interlock
No laser output if ”INTERLOCK_A” is
disabled, where ”disabled” means
contacts open. This SF complies with IEC
60825-1_2014
SF.3: Laser Stop
no laser output if “LASER_STOP_A” is
disabled, where “disabled” means
contacts open
