A cap may be detached. Attach the cap properly.
Other sensor being cascaded caused an error. Check the
indicator of the sensor.
A DIP Switch on the Intelligent Tap setting may have been
changed during operation.
Check if a DIP Switch setting was changed or not.
The communication lines or other lines may be short-
circuited or broken.
Check if the cascading or extension cables. If the
cascading cable or extension cables is broken, replace it.
An error may have occurred to the communication due to
effect of noise.
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 Intelligent Tap are arranged in parallel.
Arrange the exclusive power supply near the Intelligent
Tap or lay the power supply line of the Intelligent Tap away
from the power supply line of the machine guarded.
If the power supply for the Intelligent Tap 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.
An error may have occurred in the internal circuit.
Replace the F3SG-SR.
The power supply voltage may have dropped temporarily
when the F3SG-SR 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 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 to a power supply that is dedicated to electro-
sensitive protective devices for electro-sensitive protective
equipment such as the F3SG-SR, safety controller, etc.
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 are arranged in parallel.
Arrange the exclusive power supply near the F3SG-SR or
lay the power supply line of the F3SG-SR away from the
power supply line of the machine guarded.
If the power supply for the F3SG-SR 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.
