Description
(page 209) setpoint.
Analog Input 3 Wrn WRN
Value measured on analog input 3 is </> than Analog Protection 3
Wrn (page 210) setpoint.
Analog Input 3 Sd SD
Value measured on analog input 3 is </> than Analog Protection 3 Sd
(page 211) setpoint.
Wrn Battery Voltage WRN
Battery voltage is out of limits given by Battery Undervoltage (page
188) and Battery Overvoltage (page 188) setpoints.
Binary input Configurable Warning/BOC/Shutdown alarms on the binary inputs.
Sd Battery Flat SD
If the controller switches off during starting sequence (STARTER
(PAGE 344) output is active) it doesn’t try to start again and activates
this protection (controller assumes bad battery condition).
Sd Start Fail SD Gen-set start failed. All crank attempts were tried without success.
Parameters Fail NONE
Wrong check-sum of parameters. Happens typically after
downloading new firmware or changing of the parameter. The
controller stays in INIT mode. Check all parameters, change value of
at least one parameter.
Sd Gen Lx >V
BOC Gen Lx <V
(where x=1,2,3)
SD
BOC
The generator voltage is out of limits given by Gen <V BOC and Gen
>V Sd setpoints.
BOC Gen >,
<Frequency
BOC
The generator frequency is out of limits given by Generator
Overfrequency BOC (page 195) and Generator Underfrequency BOC
(page 196) setpoints.
BOC Overload BOC
The load is greater than the value given by Overload BOC (page 192)
setpoint.
Sd Overspeed SD
The protection comes active if the speed is greater than Overspeed Sd
(page 178) setpoint.
Sd Underspeed SD
During starting of the engine when the RPM reach the value of
Starting RPM (page 161) setpoint the starter is switched off and the
speed of the engine can drop under Starting RPM (page 161) again.
Then the Underspeed protection becomes active. Protection
evaluation starts 5 seconds after reaching Starting RPM (page 161).
Emergency Stop SD
If the input Emergency Stop is opened shutdown is immediately
activated.
GCB Fail SD Failure of generator circuit breaker.
MCB Fail WRN Failure of mains circuit breaker.
Sd RPM
Measurement Fail
SD
Failure of magnetic pick-up sensor for speed measurement. This
alarm appears, if starter was disengaged for other reason than
overcrossing Starting RPM (page 161) (like oil pressure or D+) and at
the end of timer Maximum Cranking Time (page 160) there are no
RPMs > Starting RPM (page 161) detected.
Wrn Stop Fail WRN
Gen-set stop failed. See description at Gen-set Operation States
