Section 1 Description
1-1 Features
The F3SP has two independent microprocessors forming a “dual system” and can be
used up to system with safety category 4.
One or two light curtains can be input to the F3SP, and input state will be displayed with
four input indicators (Green LEDs).
When one or both safety light curtains are interrupted, the F3SP opens both safety
output contacts.
Status indicator (7-segment display) supplies information on the state and on probable
failures.
The F3SP has both muting and override function, which forces system operation not
relate to light curtain status.
The muting function makes it possible to inactivate one or both light curtains in order to
allow, for instance, the objects passage without stopping the machine.
The override function allows the system to be manually overridden allowing material to
be cleared from the muting area if a fault has occurred.
Both the muting and the override functions force the system to work. Therefore,
activating these functions needs some precautions to avoid the reduction in safety
(Please refer to section 4-2 and 4-3).

Section 1 Description

1-2 Functions
1-2-1 Interlock function
The auto reset mode and the manual reset mode are selectable features of the F3SP.
The selection will be done by dip switch (Please refer to Section 4-1 for selection of dip
switch).
[Note]: While the F3SP is connected to power, do not change any dip switch to
avoid influence on the system safety.
1) Auto reset mode
The F3SP automatically starts after power-ON and automatically restarts after the
object in the detection zone is removed.
2) Manual reset mode
Returns to the normal operating mode only after the object has been removed and the
RESET button has been pressed.
1-2-2 Test function
1) Self-test
After power ON, the F3SP performs a complete self-test. In addition, it performs a self-
test periodically during operation.
2) External test
This is used to check if the whole system works effectively. By pressing the TEST
button (NOTE1) , this simulates the interruption of one or both safety light curtains. This
operation makes the machine stop, so the system checks can be made according to
the established time and modes.
[Note1]: TEST button must be pressed more than 100ms.
3) Error detection and restoration (Lockout condition)
If an error is detected by the self-test the F3SP enters the lockout condition, keeps the
in their OFF-state and displays the error code(*1) in status indicator.
Turning the power ON again, or applying the pressing RESET button, resets the
lockout condition.
*1. Refer to Section 7 Status indication codes for the indicating patterns.

Section 1 Description
3
1-2-3 Muting function
The muting function makes it possible to inactivate one or both light curtains in order to
allow, for instance, the objects passage without stopping the machine.
The F3SP has muting sensor inputs for the activation of this function. The muting
sensor A and B controls light curtain 1, as well as muting sensor C and D controls light
curtain 2.
For muting sensor, PNP transistor output type or N.O. contact output type is
applicable (photoelectric sensor, proximity sensor, etc.)
It is necessary to position and connect the muting sensors in order to avoid undesired
muting inputs.
It is important to remember that the muting function forces the system to work
and for this reason it must be used with care.
For detail, refer to 4-2 Muting function.
1-2-4 Override function
This function makes it possible to force a muting condition, if necessary by starting
the machine despite one or both safety light curtains having been interrupted by the
object. Thus enabling removal of the material from the protected area, when it has
been stuck in the beam of the safety light curtains due to a failure.
Suppose that a pallet has stopped before the light curtains; the conveyor belt
cannot be started again because the F3SP - after having detected one or more
interrupted light curtains- will not close the output contacts, thus making it
impossible to free the controlled area.
By starting the override function, it will be possible to carry out this operation.
It is important to remember that the override function, as well as muting function,
forces the system to work and for this reason it must be used with care.
For detail, refer to 4-3 Override function.
