On the other hand, the N/O contact is open onthe serious error, as shown in Table 9.1-4.Locking out of BO circuit operation‡BO is locked out to operate, when serious error (Level1) occurs. Serious error stops trip signalgenerations to the BO circuit. When serious error is removed, the operation will be recovered.†Note:See ChapterTechnical description: Power supply module. FAIL1 (FAIL2) contactis in Form-C; terminal-screw No. 2 & 4 (8 &10) are provided with the common.‡Note:BO is discussed in ChapterTechnical description: Binary output circuit.(iv) Affection of application operation by error levelsThe error levels influence the operation of relays and general control functions.Table 9.1-5 Operation states in the IED applications affected by the error levelsLevels Relay applications Control applications Notes0: No error – –1: Serious Stopped Stopped2: Serious (Comm.)
