Each amplifier’s DC current is continously measured and compared to a nominal value that is set by the
operator. If the measured current deviates from a +/- 15% window of the nominal (expected) value then the
amplifier is determined to be in a faulted state and will alarm. The nominal current will not normally need
adjustment unless an amplifier is swapped out. Push the PROGRAM/EXECUTE switch to go to the next
menu. Use the LEFT/RIGHT switch to move the cursor to R, then push the PROGRAM/EXECUTE switch to
jump to the SAVE SETTINGS menu.
Menu 5a Set AMP1 Nominal Current to Actual Measured Value
Menu 6a Set AMP2 Nominal Current to Actual Measured Value
Menu 7a Set AMP3 Nominal Current to Actual Measured Value
AMP1 CURRENT R
NOM=0.336
ACT=0.342
Set to actual? Y/N
This menu is simply an indication of the present value of the nominal AMPx current, as well as the actual
measured value of AMPx current. Select “Y” to reset the nominal value to the actual value that is presently
being measured. Push the PROGRAM/EXECUTE switch to go to the next menu. Use the LEFT/RIGHT
switch to move the cursor to R, then push the PROGRAM/EXECUTE switch to jump to the SAVE SETTINGS
menu.
Menu 8 Set Auto Switching Mode Priority
PRIORITY=1 R
The priority setting allows the operator to select which AMP will be backed up if both AMP1 and AMP2 are
alarmed. Use the UP/DOWN switch to select the desired priority. Select “1” to set AMP1 as the top priority.
Select “2” to set AMP2 as the top priority. Push the PROGRAM/EXECUTE switch to go to the next menu.
Use the LEFT/RIGHT switch to move the cursor to R, then push the PROGRAM/EXECUTE switch to jump to
the SAVE SETTINGS menu.
