Cause
Effect of noise is excessive.
Failure of safety output circuit.
Connection positions are reversed
for emitter(s) and receiver(s), or
their directions are upside down.
Safety output error occurred due
to short circuit, breakage, or
disconnection of series
connection cables.
Safety output lines are short-
circuited to each other after power
on.
Safety output line and 24V, 0V, or
other input/output line are short-
circuited after power on.
Safety output error occurred due
to short circuit, breakage, or
disconnection of series
connection cables.
Series connection cable is
broken.
(Test input line of a series
connection cable is broken)
A contact failure due to the loose
connector, the intrusion of liquid
(oil etc.) into the connector, or the
attachment of a foreign material
has occurred.
Solution
If other devices using the same
power supply generate noise, do
not share the same power supply
with other devices and use it as
that exclusive for the safety
component.
The inductive noise tends to be
induced especially if the power
line and the power supply line are
arranged in parallel. Arrange the
exclusive power supply near the
light curtain or lay the power line
away from the power line.
If the power supply for operation
is located near the power supply
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.
Replace the receiver.
Correct connection positions and
directions of all F3SJs.
p.57
Check if series connection cables
are connected properly. Replace a
series connection cable if it is
broken.
Wire the output lines properly.
Check the control output is in
contact with other lines at the
device or the connection.
Check if series connection cables
are connected properly. Replace a
series connection cable if it is
broken.
Replace the series connection
cable.
After cleaning the inside of the
connector (if any foreign material
is attached), tighten the connector
more closely.
