Woodward 

This is what the System Status screen would look like with the mains out of spec, 
the engine running, carrying 100 kW load isochronously, and the generator 
voltage and frequency is within specified limits. This would be a typical screen if 
the unit was set for loss of mains detection, and the mains had failed. 
 

 

Figure 4-2. System Status Screen—Isochronous 

 
 
This is what the System status screen looks like for a generator set that is base 
loaded to the mains at 500 kW, 0.80 lagging PF, with one unacknowledged 
alarm.
