The trip commands can be blocked via parameters or an appropriately configured binary signal input. This blocking is then effective for all four trip commands. The trip signals are not affected by this blocking. If the trip commands are blocked, it is indicated by the continuously illuminated amber LED indicator H 2 on the local control panel and by a signal from an output relay configured to “Blocked/Faulty”. (To identify H 2, see the dimensional drawings in the Chapter “Design”.)
