What is interlock function?
The interlock function sets an interlock under specific
conditions. (An interlock is when the machine operation is stopped and,
for Safety Light Curtains, control outputs are turned OFF.)
OMRON Safety Light Curtains have functions which use the interlock state
and others that do not use the interlock state, as outlined below.
Auto resetting does not use an interlock. In other words, after the power
is turned ON and the Sensor beam is interrupted, the control outputs will
automatically turn ON when light is incident on the Sensor.
Applicable models: F3SN Series, F3SH Series Safety Light Curtains
In an interlock, the Sensor will hold control outputs OFF and control
outputs will not turn ON even if light is incident on the Sensor. The
interlock is cleared and control outputs turn ON only after light is
incident on the Sensor, equipment safety has been confirmed, and a reset
input has been applied.
F3SN/F3SH Series has the following three modes:
(Sensors are set to use the start/restart interlock when shipped. The
setting can be changed by using the Setting Console F39-MC11.)
1. Start/Restart Interlock
The Safety Sensor is interlocked when the power is turned ON and the
Sensor beam is interrupted.
2. Start Interlock
The Safety Sensor is interlocked only after power is turned ON.
3. Restart Interlock
The Safety Sensor is interlocked only when the Sensor beam is interrupted.
