Description
independent battery charger.
Sd Stop fail
A+H
Engine stop fail indication. Stop fail means that engine
does not reach “still engine” state within Engine params:
Stop time.
“Still engine” conditions:
- Engine speed (RPM) = 0 and
- AI: Oil press < Starting POil and
- D+ terminal is not active and
- BI: RunIndication 1 and 2 and 3 are not active and
- Generator voltage < 15V (in all phases) and
- Generator frequency = 0 Hz
- if all these conditions are fulfilled, additional 2s delay is
used to confirm “still engine” state.
Overspeed
A+H
Gen-set over speed alarm is based on Engine
protect:Overspeed setpoint setting.
Underspeed
A+H
Genset under speed alarm indication. Under speed limit is
based on Engine params:Starting RPM setting. This
protection is activated after successful engine start if
engine speed drops below value given by Starting RPM
setpoint setting (for more information see Engine starting
procedures description in a Reference Guide ).
Pickup fail
A+H
Pickup fail indication. Pickup fail means loss of RPM signal
in running state (“engine running” state is active).
“Engine running” conditions:
- Engine speed > Engine params: Starting RPM or
- AI: Oil press > Starting POil or
- D+ terminal active (this condition is used only if Engine
params: D+ function = ENABLED) or
- BI: RunIndication 1 or 2 or 3 is active or
- Generator voltage > 15V (in any phase)
See Speed pick-up input section in the Technical data
chapter in IGS-NT-x.y.-Installation Guide manual for
information about requested pick-up signal parametres.
Sd BatteryFlat
A+H
Alarm is activated if controller “wakes up” after a start
attempt which caused battery voltage drop (voltage drop
below 6V) and consequently controller switch-off. ComAp
I-LBA module may help to solve this problem, for
information about this module see IGS-NT-x.y.-Installation
Guide manual.
WrnServiceTime
A+H
This alarm is acivated when at least one of controller count
down service timers Engine protect:Service time X has
reached zero. It is necessary to set again a non-zero value
to a corresponding setpoint to reset this alarm.
Not lubricated
A
This Alarm list message is active until the first lubrication
cycle has been finished.
See Engine states chapter in IGS-NT-x.y-Reference
Guide.
Start fail
A+H
This alarm is issued if genset start-up fails. It means that
several crank attempts has been done (number of attempts
is given by Engine params: Crank attempts) and engine
did not start.
For more information see Engine starting procedures
chapter in IGS-NT-x.y-Reference Guide.
Start blocking
A
This message means that a binary input with Startblocking
function is active and engine start is blocked. If active,
