Instruction manual

6) Apply full loads to each phase. Verify that the voltage of each phase remains

within 0.135 volts of the no-load voltage. The waveforms shall still appear

clean on the oscilloscope and have less than 2% distortion. (Full load is 3.0A

per 6KVA phase at 135 volts output.)

7) Program the Current Limit to 25.0 amps:

8 ENT

25 PRG ENT

8) The display should show the error message 'CRL FAULT'. The output will

default to a programmed value of 0.0 volts.

If the FCS 18 has the PRC Option installed, perform the following steps:

9) With the front panel keypad, program the HI output voltage range with the

following key sequences:

4 ENT To select the Range screen (RNG)

To program the HI range (ex., 270 volt range):

270 PRG ENT

10) Program the output to maximum voltage with the following key sequences:

Depress the MON key 1 time to select the Amplitude screen (AMP).

To program the voltage to maximum.

(Maximum Range value) PRG ENT

Verify that the front panel voltmeter indicates approximately the programmed

value for all three phases or for phase A for a 1-phase system.
