Image 5.15 Analog input alarm evaluation principle
Alarm handling
There are three different alarm categories regarding the period when the alarms are evaluated. The category is
selectable for alarms assigned to binary/analog inputs and fixed for built-in alarms. The categories are the
following:
The alarm is evaluated all the time when the controller is switched on.
The alarm is evaluated only when the engine is running. This type should be used for e.g. oil pressure. These
alarms begin to be evaluated after the engine has been started with the delay given by the setpoint
.
The alarm is evaluated only when the generator is excited. These alarms begin to be evaluated after the
engine has been started and
Maximal Stabilization Time (page 172)
has elapsed or the GCB has been closed.
They remain evaluated until cooling has finished. Only Generator under/overvoltage, Generator voltage
unbalance and Generator under/overfrequency belong to this category. This category is not configurable to
binary and analog input alarms.
If an alarm is being evaluated and the appropriate alarm condition is fulfilled, the delay of evaluation will start to
run. The delay is adjustable by a setpoint (in the case of built-in alarms, analog input alarms) or is adjusted via
configuration window in LiteEdit2015 (in the case of binary input alarms). If the conditions persist, the alarm will
activate. The alarm will not activate if the condition is dismissed while the delay is still running.
After pressing the Fault reset button or activating the binary input
, all active
alarms change to confirmed state. Confirmed alarms will disappear from the Alarmlist as soon as the respective
condition dismisses. If the condition is dismissed before acknowledging the alarm, the alarm will remain in the
Alarmlist as Inactive.
Note:
The input
can be used for temporary disabling of red alarms to shutdown the
engine. This input may be used in situations where providing the power is extremely important – e.g. if the gen-
set drives pumps for fire extinguishers (sprinklers).
Alarm states
An alarm can have following states:
