Alarm Management
Following alarms are available:
Sensor Fail
Warning
Breakers open and cooling (BOC)
Shut down
Mains failure
Sensor Fail (FLS)
Sensor Fail of analog inputs is detected in three ways. First when measured resistance value is lower
than half of the lowest point of sensor characteristics. Second when measured resistance value is
higher than 112,5% of highest point of sensor characteristics. Or when data from ECU are missing.
Sensor Fail is indicated by ##### symbol instead measured value.
Sensor Fail is only evaluated for values of sensor curve within range 1..14999Ohm.
When the sensor characteristic curve consists values “0” or “15000”, the sensor fault for
shortcircuit/sensor fail is not evaluated.
Maximum allowable resistance value for sensor characteristics is 15000 Ohms.
Warning (WRN)
When warning comes up, only alarm outputs and common warning output are closed.
Possible warnings:
See List of possible events
Breaker open and cooling (BOC)
When the BOC alarm comes up, IL-NT opens first output GCB CLOSE/ to unload the gen-set and
then after cooling time it also stops the gen-set. Alarm outputs and common shutdown output are
activated. Active or not acknowledged protection disables gen-set start.
Possible BOC alarms:
