The communication lines or other lines may be short-circuited
or broken.
Check the cables for cascading or extension cables.
If the wiring is extended with cables other than specified, the
cables used for extension may not have performance
equivalent or greater than the specified cables. Use cables
with the same performance or more than the specified cables.
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 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.
5-4-4. Functional Earth Connection
The internal circuit of the Intelligent Tap may be defective.
Replace the Intelligent Tap.
