6F2T0207 (0.01)GRE200 (5,6)- 801 -(iii) Fail output and BO circuit driveAutomatic supervision function can drive Fail contact (N/C or “b” contact) on BIO module atT1† when an error occurs without warning. Note that, the drives for respective BO circuits‡on BIO will be locked out when serious error (Level 1=Critical error) is detected.Table 10.1-4 FAIL contact, BO, LED outputs depending on levelsErrorLevelsFAIL† contact outputs BO‡ locked out ErrorLEDScrew No. 19 (N/C)0: No error Open Not locked out Off1:Serious Closed Locked out On2:Serious(Comm.)

Table 10.1-4 shows N/O contact is open, except serious error.Locking out of BO circuit drive‡BO operation will be locked out, when serious error (Level1) is detected. Note that it will stopissuing trip commands on BO circuits. If the error is cleared, the operations will be back.†Note:See ChapterTechnical description: DC power and Fail terminals. (→p. 672).‡Note:BO is discussed in ChapterTechnical description: Binary output circuit (→p. 650).(iv) Affection of application operation by error levelsThe error levels influence the operation of relay and control and monitoring application.Table 10.1-5 Operation states in the IED applications affected by the error levelsLevels Relay applications Control and monitoring applications Notes0: No error – –1: Serious Stopped Stopped2: Serious (Comm.)
