Error History
Section 7-3
Safety Output Terminal-related Failures
Cross Connection 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 positive side of
the power supply.
• Make sure there is not a short circuit between output signal wires.
• Make sure the power supply voltage is set within the specification
range.
To recover from these failures, the following conditions are required:
The latch output error time must have passed, and the cause of the
error must have been removed.
The output signal from the user application for the target safety output
must turn OFF.
Stuck-at-high Detected at Safety Output
Short Circuit to Low at Safety Output
Over Current Detected at Safety Output
Dual Channel Output Failure
Check the program to see if output data for dual channels are the same.
Internal Relay Relevant Circuit Error at
Safety Relay Output
• Check whether noise interference is excessive.
Relay Failure
Replace the safety relay.
EDM Error
Check the following items.
• Is the output signal line broken?
• Is the output signal line grounded?
• Is the output signal line in contact with the power supply (positive
side)?
• Is there a contactor or relay contact weld fault?
