C-shape
Note
When the short-circuit/overload protection is activated for a contact point, the output for that point is turned
OFF. At the same time, lamp “F” lights up, and the alarm from AR0205 to AR0214 corresponding to the I/O
number turns ON. After the cause of the error has been removed, the alarm will be cleared automatically
when the internal temperature of the element drops.
