Alert Statements in this Manual
For users
The F3SJ must be installed, configured, and incorporated into a machine control system by a
sufficiently trained and qualified person. An unqualified person may not be able to perform these
operations properly, which may cause a person to go undetected, resulting in serious injury.
When changes are made to each function using the setting tool (F39-GWUM or F39-MC21), the
administrator must manage the details of the changes and perform the changes. Accidental
functional setting change may cause failure of human body detection, resulting in a serious
injury.
For machines
Do not use this sensor for machines that cannot be stopped by electrical control. For example,
do not use it for a pressing machine that uses full-rotation clutch. Otherwise, the machine may
not stop before a person reaches the hazardous part, resulting in serious injury.
Do not use the auxiliary output or external indicator output for safety applications. Human body
may not be detected when F3SJ fails, resulting in serious injury.
