4.4.6 CURRENT
LIMIT CALIBRATION
1.
Select the Current Limit (CRL) screen (Screen 8) and program the Current Limit PROGRAM VALUE
from Table 4-1.
2.
Monitor the power system phase A output current with the external current transformer and AC DVM.
Connect an oscilloscope to the output.
3.
Program the low voltage range and the voltage to 80% of range. Program the frequency to 60 Hz.
4.
Apply the LOAD RES value from Table 4-1 to the power system phase A output only.
5.
Increase the output amplitude slowly until the external AC current transformer indicates SET VALUE
from Table 4-1. Slowly turn A9-R17 on the Current Limit Assembly in a counterclockwise direction
until the output OVERLOAD indicator starts to illuminate.
6.
Slowly readjust R17 in a clockwise direction just to a point that the OVERLOAD extinguishes. Repeat
this step for all ADJUSTMENTS listed in Table 4-3 for phase A.
7.
Remove the load for phase A and repeat steps 2) through 6) for phase B and C. Adjust the controls
specified in Table 4-3 for phase B and C.
8.
Program the CRL value to 5 amps and full voltage. Verify the output faults when any phase has the
LOAD RES load value.
