External wiring
error in safety
input.
Check the following points:
• Make sure the input signal
wire is not contacting the
power source (positive side).
• Make sure the input signal
wire does not have an earth
fault.
• Make sure the input signal
wire is not disconnected.
• Make sure there is not a short
circuit between input signal
wires.
• Make sure there is no failure in
the connected devices.
• Make sure the Discrepancy
Time setting values are valid.
To recover from the above
error state, the following condi-
tions are required.
Latch input error time must
have passed and the root cause
must have been removed.
The target safety input terminal
inputs must turn OFF.
To change the discrepancy
time, reconfiguration is
required.

at Test Output
See note

Overloading was
detected at test
output (when a
test output termi-
nal was set as a
standard signal
output).
Check whether the output
signal wire has an earth fault or
is over loaded.

Stuck-on-high at
test output (when
a test output ter-
minal was set as
a standard sig-
nal output).
For the wires, check if the
power supply source (positive
side) is contacting the output
signal wire. After the latch input
error time has passed, turn OFF
the input after the cause of the
error has been removed. The
error will be reset. If there is no
fault with the wires, replace the
unit.
