6.7. Alarm Management
The following alarms are available:
• Breaker open and cooling (BOC)
• Warning
• Shut down
Breaker open and cooling (BOC)
When the control panel detects a problem related to the alternator. The panel stops the genset
gradually.
Warning (WRN)
Warning. No reason to stop the group. This is a warning to informative level. Normally it is a
value of a parameter that is below / above the standard value but does not exceed the limit pre-
configured to stop the engine.
Shut Down (SD)
When the Control Panel orders drastically stop the engine.
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.
