Binary inputs of oil level SENLVLALM, SENLVLLO and oillevel signal SENLEVEL are taken into account to initiate the alarm LVLALM andthe lockout LVLLO. When SENLEVEL is less than LevelAlmLimit or binary signalfrom oil insulated device SENLVLALM is high, the oil level indication alarmLVLALM will be initiated. Similarly, if oil level input SENLEVEL is less thanLevelLOLimit or binary signal from oil insulated device SENLVLLO is high, theoil level indication lockout LVLLO will be initiated.There may be sudden change in oil level for a very small time, for which thefunction need not to initiate any alarm. To avoid the intermittent alarm, two timedelays tLevelAlarm or tLevelLockOut have been included. If the oil level goesbelow the settings for more than these time delays, the corresponding alarmLVLALM or lockout LVLLO will be initiated. The SETLLO binary input is usedfor setting the liquid level lockout LVLLO. The LVLLO output retains the lastvalue until it is reset by using the binary input RESETLO. The binary inputBLKALM can be used for blocking the alarms, and the BLOCK input can blockboth alarms and the lockout indication.Temperature of the medium is available from the input signal of temperature. Thesignal is monitored to detect high temperature.When temperature input SENTEMP is above TempAlarmLimit, temperature alarmTEMPALM will be initiated. Similarly, if temperature input SENTEMP is aboveTempLOLimit, temperature lockout TEMPLO will be initiated.There may be sudden change in temperature of the medium for a very small time,for which the function need not to initiate any alarm.
