Error code
-- The setting of the operating range selection may be incorrect.
• F3SG-RA: Check if the Operating Range Selection of the DIP Switch is
properly set.
• F3SG-RE: Check if the Operating Range Select Input line is properly wired.
• F3SG-RE with Y Joint Connector: Check if the cables are properly wired to
the connector.

19 The power supply voltage may have dropped temporarily when the F3SG-R 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-R 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-R to a power supply that is dedicated to electro-sensitive
protective devices for electro-sensitive protective equipment such as the
F3SG-R, 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-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.
19 The power supply voltage may have dropped temporarily when the F3SG-R 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.
1A Communication error may have occurred due to noise.
Check the noise level in the environment.
19, 1A The internal circuitry may be defective due to power supply voltage or noise.
Check the noise level in the environment.
Make sure that the power supply voltage is 24 VDC±20%.
If the indicator still shows this error, replace the F3SG-R.
-- The internal circuitry may be defective due to noise.
Check the noise level in the environment.
Communication error may have occurred due to noise.
Check the noise level in the environment.
