5.8.4.4 SUMMARY
You can think of the settings as Analogue output voltage is SW1 ± SW2
In the example above this means the analogue output is 1.0V ± 1.5V (based upon the settings of SW1=2 and
SW2=2
SW1 is the voltage above (or below) 0V that the analogue output will produce to instruct ‘no change’ to the
voltage/frequency of the genset.
SW2 is the maximum voltage above (and below) SW1 that the analogue output will produce to instruct the
voltage/frequency of the genset to change.
