Indicates that when the fault hasbeen cleared upon circuit breaker reclosure, and has not reappearedbefore expiry of the reclaim time.Recloser blocking signal. Generated by:- auxiliary power supply failure during dead time (definitivetrip).- external blocking signal. External blocking can be setby the user in the PROTECTION G1 / [79]AUTORECLOSE/Ext Block menu. This blocking signal isprovided via a logic input assigned to the Block_79 functionin the AUTOMAT. CTRL/Inputs menu.- definitive trip.- remote trip command during the reclaim time.- pick-up of I2> or thermal trip during dead time.- breaker failure (circuit breaker failure to trip on expiry oftBF).- breaker operating time (or tripping time) longer than the settime.Configuration conflict of the re-close function. This signal isgenerated by:- O/O Interlock not assigned to a logic input or assigned butnot wired to the input.- no output relay assigned to the CB CLOSE function(AUTOMAT. CTRL/Output Relays menu ).- trip contact latched.- no re-close cycle assigned to the protection functions(PROTECTION/ [79] Autoreclose menu ).MAINTENANCE MODEThe relay is in maintenance mode.1.4.2 Relay Hardware or Software Warning MessagesAny software or hardware fault internal to MiCOM relay generates a "hardware/softwarealarm" that is stored in memory as a "Hardware Alarm". If several hardware alarms aredetected they are all stored in their order of appearance. The warning messages arepresented on the LCD in reverse order of their detection (the most recent first and the oldestlast). Each warning message is numbered and the total stored is shown.The user can read all warning messages pressing , without entering the password.It is not possible to acknowledge and clear warning messages caused by internal relayhardware or software failure. This message can only be cleared once the cause of thehardware or software failure has been removed.The control of the WARNING LED (LED 3) is directly assigned to the status of the warningmessages stored in the memory.If the internal hardware or software failure is major (i.e. the relay cannot perform protectionfunctions), the WARNING LED (LED 3) lights up continuously.− major fault: Protection and automation functions of the equipment are blocked. In thiscondition, the protection relay detects the corresponding fault and activates RL0 WatchDog relay (35-36 terminals contact is closed).For instance: the “DEF. ANA” fault (fault in the analog circuit channel) is considered as amajor fault because the protection functions will not operate correctly.− minor fault: Protection and automation functions of the relay operate. A minor fault will notactivate RL0 Watch Dog relay (35-36 terminals contact is closed, 36-37 terminals isopen). This fault causes a LED alarm and is displayed on the LCD panel.
