The LED RUN and ERROR Indicators are Blinking
Simultaneously Every 0.5 Seconds
The blinking happens when the firmware of the CPU module is being upgraded. If this happens once the power is
supplied to the CPU module, it means errors occurred during the previous firmware upgrade. Users need to upgrade the
firmware again or contact your point of purchase.
12.2.8
The RUN and ERROR LED Indicators are Blinking One After
Another Every 0.5 Seconds.
The blinking happens when the CPU module memory card is backing up, restoring, or saving.
If you are using AS218 Series CPU and without engaging any SD card, the RUN and LED indicators blinking indicates
the AIO firmware is being updated. If the blinking happens at the instant when the CPU is supplied with power, the
blinking means AIO firmware update failed and you need to update the firmware again. If you are not updating the AIO
firmware, the blinking indicates CPU error and you need to contact the local authorized distributors.
