Safety output error due to power
supply voltage or noise X X 19 The power supply voltage may have dropped temporarily
when the F3SG-SR/PG is in operation. Check for
temporary power supply voltage drop (by about 12 VDC)
by the influence of the inductive load, etc.
If the exclusive power supply is not used, check the power
consumption of other connected devices for enough
capacity.
Power supply voltage may be outside the rated range.
Connect the F3SG-SR/PG to a 24 VDC±20% power
supply voltage.
Voltage fluctuation may have occurred due to insufficient
power supply capacity.
Replace the power supply with one that has a larger
capacity.
Instantaneous break or instantaneous stop may have
occurred due to power sharing with other devices. Do not
share the power supply with other devices. Connect the
F3SG-SR/PG to a power supply that is dedicated to
electro-sensitive protective devices for electro-sensitive
protective equipment such as the F3SG-SR/PG, safety
controller, etc.
1A 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-SR/PG are arranged in parallel.
Arrange the exclusive power supply near the F3SG-SR/PG
or lay the power supply line of the F3SG-SR/PG away from
the power supply line of the machine guarded.
If the power supply for the F3SG-SR/PG is located near
the power supply of the machine guarded and it shares the
same grounding wire, it is subject to the influence of
common mode noise.
Separate the grounding point or use it as the exclusive
ground.

error X X EB The setting of the operating range selection may be
incorrect.
• When the Intelligent Tap is connected, check if the
Operating Range Selection of the DIP Switch is properly
set.
• When the Intelligent Tap is not connected, check if the
Operating Range Select Input line is properly wired.
