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 Encoder control.
The changing average value is displayed on the
ammeter. Example: If EN Amperage is 150, EP Am-
perage 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 En-
coder control until 69 amps is displayed, the EN am-
perage is now 75 and EP amperage is now 50. The
balance remains 75%, and the frequency is still
120, and the 1.5 to 1 EN amperage to EP amperage
ratio is maintained.
