Auxiliary Output; External Indicator Output - Omron F3SN-A Series Instruction Manual

3) Error detection and restoration (Lockout condition)
If an error is detected by the self-test the light curtain enters the lockout condition, keeps the OSSD outputs
in their OFF-state and displays the error mode
Turning the power ON again, or applying the reset input
(For noise, eliminating the noise automatically resets the lockout condition.)
*1. Refer to "1-2-10 Indicators" for the indicating patterns.
*2. In case of manual reset mode: Apply a voltage of 24VDC (9VDC to Vs, nominal 24VDC) to the reset input

1-2-3 Auxiliary Output

The default of this output is the reverse signal of the
safety outputs (Dark-ON output). This output can be
used for monitoring purposes by connecting it to a device
such as a PLC.
The auxiliary output can be selected to give one of the
following output operation modes by the F39-MC11.
• Dark-ON output mode
• Light-ON output mode
• Light diagnosis mode
• Lockout mode
• Outermost-beam monitoring mode
• Specified-beam mode
• Blanking monitoring mode
The diagram on the right shows the timing chart for the Dark-ON output mode. For detailed information, refer
to the instruction manual of the F39-MC11.

1-2-4 External indicator output

This output can be connected to an external indicator to
display one of the operation modes as selected by the
F39-MC11. The default of this output is Light-ON output.
Selectable output modes are as follows.
• Dark-ON output mode
• Light-ON output mode
• Light diagnosis mode
• Lockout mode
The diagram on the right shows the timing chart for the
Light-ON output mode. For detailed information, refer to
the instruction manual for the F39-MC11.
The large indicator can be directly attached to the light curtain
by using the external indicator F39-A01P - (optional), as
shown in the figure on the right, for use with series-connection
types only.

to the light curtain, resets the lockout condition
line for 100 ms or more, then remove power to the reset input line or apply a
voltage of 0VDC.
Open the reset input line or connect it to 0VDC for 100ms or more, then
re-apply a voltage of 24VDC (9VDC to Vs, nominal 24VDC).
