Two binary output signals are used from the circuit breaker to initiate alarmsignals, level below alarm level and level below lockout level. If the input signalLVL_ALM is high, which indicate that the oil level in the circuit breaker is belowalarm level, the output signal LVL_ALM, level below alarm level, will be initiated1MRK 511 287-UEN A Section 12Monitoring487Technical manual
