*1
terminal.
On: An error occurred (minor error).
Flashing: An error occurred (moderate error).
Off: Normal operation
Depending on "LED display settings during an error", displays the wait-for-restart state after the safety
module is enabled or the error occurrence state.
• When "Do not display I/O error" is set
Flashing (400ms cycle): Wait-for-restart
Off: Normal operation
• When "Always display I/O error" or "Display I/O status and error switching (1 second interval)" is set
A minor error occurrence can be checked.
