6.4.2 Current Limit Adjustment
Note: If the Current Limit and High Current Measurement Range Adjustments
are both adjusted, the High Current Measurement Range must be
adjusted first.
1. Connect the test equipment as shown in Figure 6-2. Use full load resistance for the low
voltage range.
2. Program the current to 4.5 amps. Program the output to 135 V (115 V for the –AV
option, 156V and 3.9 amps for 2003RP-HV, adjust for 4.1 in step 3) on the low voltage
range and 400 Hz.
3. For Phase A, adjust R50 on the Controller board for an output current of 4.75 amps.
For Phase B, adjust R49 on the Phase B/C board for an output of 4.75 amps.
For Phase C, adjust R8 on the Phase B/C board for an output of 4.75 amps.
CAUTION: The amplifier wind tunnel must be covered for proper cooling if the
adjustment takes more than 1 minute.
