Download Errors and
Corrective Actions The controller may return an error response when downloading configuration
data to the controller. Use the messages displayed in RSNetWorx for DeviceNet
software to identify the error.
Table 24 - Safety Input Error Messages
Message Description Corrective Action
External Test Signal Failure at
Safety Input A failure has occurred in the external wiring at the safety
input. 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 the input signal wires.
Make sure a failure has not occurred in the connected device.
Make sure the configured value of the discrepancy time is valid.
To recover from this error state, the latch input error time must have passed and
the cause of the error must have been corrected. The target safety inputs must
turn off.
To change the discrepancy time, you must reconfigure the safety input.
Discrepancy Error at Safety Input
A discrepancy exists between two inputs configured as Dual
Channel.
Internal Input Failure at Safety
Input An internal circuit failure occurred at the safety input. Replace the unit if the system failure occurs again after cycling the power
supply.
Table 25 - Test Output Error Messages
Message Description Corrective Action
Overload Detected at Test
Output Too much current is being drawn at the test output. Check whether the output signal wire has an earth fault or is overloaded.
Stuck-at-high Detected at Test
Output A test output is stuck on. Check whether the power source is contacting the output signal wire. After the latch input-
error time has passed, turn off the input when the cause of the error has been removed,
and the error will be reset. If there is no fault with the wires, replace the unit.
Under-current Detected Using
Muting Lamp The lower limit error of current was detected at the
test output T3. Check whether the output signal wire is disconnected or if the muting lamp is burned out.
If there is no fault with the wires, check the status indicators.
Table 26 - Safety Output Error Messages
Message Description Corrective Action
Over Current Detected at Safety Output Overcurrent was detected at the safety output. 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 the output signal wires.
Short Circuit Detected at Safety Output A short-circuit was detected at the safety output.
Stuck-at-high Detected at Safety
Output A safety output is stuck-at-high.
Cross Connection Detected at Safety
Output A short-circuit was detected between output signal wires
at a safety output.
Dual Channel Violation at Safety Output Output data error has occurred at a safety output. Check whether the data of the two outputs in the Dual Channel mode are
configured as equivalent channels.
