Properarc extinction by the compressed gas in the circuit breaker is very important. When thepressure becomes too low compared to the required value, the circuit breaker operation shallbe blocked to minimize the risk of internal failure. Binary information based on the gaspressure in the circuit breaker is used as an input signal to the function. The functiongenerates alarms based on the received information.13.2.3 Setting guidelines GUID-DF6BEC98-F806-41CE-8C29-BEE9C88FC1FD v1The parameters for the gas medium supervision SSIMG are set via the local HMI or PCM600.•Operation:Off/On•PresAlmLimit: Alarm setting pressure limit for gas medium supervision•PresLOLimit: Pressure lockout setting limit for gas medium supervision•TempAlarmLimit: Temperature alarm level setting of the gas medium1MRK 504 158-UEN A Section 13Monitoring207Application manual
