2) Manual reset mode ( Start / restart interlock)
After the power is turned ON, or when at least one beam is interrupted, the light curtain enters the interlock
condition.
When the light curtain enters the interlock condition, it keeps the OSSD outputs in the OFF-state. Even if all
beams become free, the OSSD outputs will not go to the ON-state. When none of the beams are
interrupted in the detection zone, applying the reset input
(*1)
resets the interlock condition and the OSSD
outputs go to the ON-state.
*1. Apply a voltage of 24VDC (9VDC to Vs, nominal 24VDC) to the reset input line for 100 ms or more, then
remove power to the reset input line or apply a voltage of 0 VDC.
To enable manual reset mode:
Connect the Interlock selection input line to 24VDC (9VDC to Vs, nominal 24VDC)
Connect the reset input line to 24VDC (9VDC to Vs, nominal 24VDC) via a reset switch (normally open
contact ).
Turn on the power to the light curtain while the reset switch contact remains open.
[Note1]:
The switch to reset the interlock condition has to be installed out of the hazardous area.
Before the start/restart interlock is reset, the hazardous area must be visibly free of
personnel.
[Note2]:
Prevent short-circuiting of unconnected wires of the light curtain with other wires .
1-2-2 Test function
1) Self-test
After power ON, the F3SN-B performs a complete self-test within 1 second. In addition, it performs a
self-test (every 1 second) periodically during operation.
2) External test
This function will stop the light-emitting of the light curtain
at any time to confirm the output is turned OFF normally.
Applying a voltage of 24VDC (9V to Vs, nominal 24VDC)
(NOTE1)
to the test input line of the emitter makes the emitter
stop emitting.
[Note1]:
Applied time should be more than four
times of T
OFF
.
[Note2]:
For T
ON
and T
OFF
, refer to "1-3 Ratings and Performance."
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
(*1)
.
Turning the power ON again, or applying the reset input
(*2)
to the light curtain, resets the lockout condition
(For noise, eliminating the noise automatically resets the lockout condition.)
*1. Refer to “1-2-6 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
line for 100 ms or more, then remove power to the reset input line or apply a
voltage of 0VDC.
In case of auto reset mode: 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).
