Error History
Section 10-4
Over Current Detected
at Safety Output
Overcurrent was detected
at safety output.
Check the following points:
• Make sure there is no overcurrent 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 failures, the following conditions are
required:
Latch output 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.
Short Circuit Detected at
Safety Output
Short circuit was detected
at safety output.
Stuck-at-high Detected
at Safety Output
Stuck-at-high at safety
output
Cross Connection
Detected at Safety
Output
Short circuit was detected
between output signal
wires at safety output.
Dual Channel Violation
at Safety Output
Output data error at safety
output
Check whether the data of the two outputs in the Dual Channel
Mode are configured as equivalent channels.
