Non-Routine Output Gain Calibration

If the Current Limit board assembly (P/N 7004-703-3) is replaced in the field or one of the
amplifiers has been replaced, it is necessary to check the gain of each phase and adjust as
needed.
WARNING: This requires the top cover to be removed and should be done by qualified
service personnel only. Dangerous Voltages are present inside the AC power
source.
6.7.1 Output Signal Gain Adjustment
Note: For multi-box power systems, eg. 9000CS/2, the output signal gain adjustment
should be done with only the Master power source. Remove all auxiliary power
sources and disconnect the system interface cable to the Master power source.
To adjust internal output gains, proceed as follows:
1. Loosen the top cover and slide back until the Current Limit board assembly (P/N 7004-
703-3) is uncovered. This is the vertical board directly behind the CPU/Controller board.
Refer to Figure 6-1.
2. Go to the Output Calibration screen by repeatedly pressing the MENU key until OUTP
CAL is displayed.
