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 corresponding Flag in the Basic I/O Unit Information Area
(AR0205 to AR0214) will turn ON. After the cause of the error has been removed, the alarm will be cleared
automatically when the internal temperature of the element drops.
