5. Alarm Management
The following alarms are available:

Sensor Fail

Warning

Shut down
5.1 Sensor Fail (FLS)
Sensor Fail is detected when the measured value is 6 percent out of range. Controller screen
displays in this case string ##### instead of the measured value.
5.2 Warning (WRN)
When warning comes up, any measured value is lower/greater than setpoint. See List of
possible events.
5.3 Shut Down (SD)
When the shut-down alarms come up, SCO 10 stops the engine immediately. See List of
Possible events.
5.4 Voltage phase sequence detection
SCO 10 controller detects phase sequence on generator voltage terminals. This protection is
important after controller installation to avoid wrong voltage phase connection. The following alarms
can be detected:
Wrong phase sequence
There is a fix defined phase sequence in SCO 10 controller L1, L2, L3. When the phases are
connected in different order (e.g. L1, L3, L2 or L2, L1, L3) the following alarms are detected:
Gen CCW Rot = wrong generator phase sequence
Hint:
Phase sequence detection is active when voltage in all three phases is >50VAC and all phases
angles are in the range 120° ± 20.
Phase sequence alarm detection is 1 sec delayed to avoid transient effects.
