Speed dn is used (i.e. at least one of these outputs is configured onto a physical 
or virtual output terminal).  
 
 
Alarm output: WrnVoltRegLim 
This output is closed while the WrnVoltRegLim alarm is present in the alarm list, 
i.e. while the analog output for AVR is near minimum or maximum position (out of 
the range 2% to 98% for more than 2s). 
NOTE:  
This alarm is disabled when AVR control via binary outputs AVR up and AVR dn 
is used (i.e. at least one of these outputs is configured onto a physical or virtual 
output terminal).  
 
 
Alarm output: WrnTestOnLdFail 
This output is closed while the WrnTestOnLdFail alarm is present in the alarm list. 
This alarm indicates that the Test on load function has failed, i.e. the controller is 
in TEST mode, the input Test on load is closed, however, when the gen-set has 
been synchronized to the mains and load ramp has been finished there is still 
nonzero import from the mains, because the load is higher than the gen-set 
capacity. 
 
Alarm output: Sd Oil press B 
This output is closed while the Sd Oil press B alarm is present in the alarm list, i.e. 
while there is a mismatch between gen-set state (running/stopped) and position of 
the input Oil press. 
 
Alarm output: OfL StartBlck 
This output is closed while message OfL StartBlck is present in the alarm list. The 
message indicates that the setpoints Island enable, ParallelEnable and Synchro 
enable are adjusted in such a way, that the genset is not allowed to operate in 
current conditions, for example if mains breaker is opened and however island 
operation is disabled. 
 
Alarm output: Start blocking 
The output is closed while there is the message Start blocking in the alarm list, i.e. 
while the input Startblocking is closed. 
 
Alarm output: Fuel theft
