Meaning
Memory error on These are S8AS system errors.
power supply side
When one of these error codes is displayed, check the system config-
uration and clear the error, and then turn the power supply OFF and
S8AS hardware error
ON again.
Power supply voltage
If the error code persists, contact your OMRON representative

corrupted.
Abnormal voltage trip- The power supply voltage
ping exceeded 28.8 V.
Abnormal current trip- The branch output's current
ping exceeded the current tripping
threshold.
Total current tripping All branch outputs were cutoff
because the total current and the
power-ON time exceeded the
abnormal total current tripping
conditions.
Undervoltage alarm The output voltage dropped
below the undervoltage detection
threshold.
Maintenance forecast The replacement time calculated
monitor output by the S8AS is lower than the
notification time.
Overheating alarm The S8AS is overheated
Over-temperature out- The S8AS's internal temperature
put exceeded the over-temperature
output threshold.
• When two or more errors occur simultaneously, the higher priority error
(higher in the table above) will be displayed.
Probable cause and remedy
Press the Mode Key to switch to
the parameter initialization dis-
play. After initializing the parame-
ters, set them again.
This error is treated as a system
error for the S8AS-24006N/
48008N.
Check the power supply voltage.
Check whether the connected
device is correct and check
whether the set value is appropri-
ate.
Check whether the connected
devices are suitable and operat-
ing within the total current limit.
Check the power supply voltage
and the set value.
Indicates that the replacement
time is approaching.
Take steps to reduce the internal
temperature.
Check for a high ambient temper-
ature and check the setting of the
over-temperature output thresh-
old.
Take steps to reduce the temper-
ature in the control panel.
