5 Amperage Control
Average Amperage Control: Setting EN Amper-
age, EP Amperage, Balance, and Frequency val-
ues creates an average amperage. The operator
can change the average amperage value while
maintaining the same EN amperage to EP amper-
age ratio at the existing balance and frequency. To
change the average amperage value, press the
Amperage switch pad and turn the amperage ad-
justment control control. The changing average val-
ue is displayed on the ammeter. Example: If EN Am-
perage is 150, EP Amperage is 100, Balance is
75%, and Frequency is 120, the average amperage
is 138 amps. If you press the Amperage switch pad
and turn the amperage adjustment control control
until 69 amps is displayed, the EN amperage is now
75 and EP amperage is now 50. The balance re-
mains 75%, and the frequency is still 120, and the
1.5 to 1 EN amperage to EP amperage ratio is main-
tained.
