Over Current
Detected at Safety
Output
See note
1.
Overcurrent was
detected at
safety output.
Check the following points:
• Make sure there is no overcur-
rent for the output.
• Make sure the output signal
wire does not have an earth
fault.
• Make sure the output signal
wire is not contacting the
power source (positive side).
• Make sure there is not a short
circuit between output signal
wires.
To recover from these errors,
the following conditions are
required:
Latch input error time must
have passed, and the root
cause must have been
removed.
The output signal from the user
application for the target safety
output must turn OFF.
