7-1-3. Troubles Other Than in Lockout State
Shown below are actions to take when F3SG-R does not work properly while no lockout occurred and
no error is displayed.
The COM indicator is illuminated with all beams of F3SG-R blocked or light emission stopped.
Description Cause and Measures
Malfunction due to noise Effect of noise may be excessive.
If other devices using the same power supply generate noise, do not share the same power supply with
other devices, and use a separate power supply exclusively for the safety components.
The inductive noise tends to be induced especially if the power supply line of the machine guarded and
the power supply line of the F3SG-R are arranged in parallel.
Arrange the exclusive power supply near the F3SG-R or lay the power supply line of the F3SG-R away
from the power supply line of the machine guarded.
If the power supply for the F3SG-R is located near the power supply of the machine guarded and it
uses the same ground, it is subject to the influence of common mode noise from the ground.
Separate the grounding point or use it as the exclusive ground.
