3)
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
4)
Verify the HIGH RANGE lamp is lit.
5)
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
6)
Verify that the front panel voltmeter indicates approximately the programmed value for all three phases
or for phase A for a 1-phase system.
7)
Program the AC Power System to the low range with the following keystrokes:
4 ENT (low voltage range value) PRG ENT
8)
Program the output to the maximum low voltage range voltage:
5 ENT (maximum low voltage range value) PRG ENT
9)
Observe each of the outputs with the oscilloscope or distortion analyzer. The outputs should be clean
sine waves having less than 1.0% distortion.
10)
Apply full loads to each phase (Refer to Table 4-1). Verify that the voltage of each phase remains
within (0.0005 x voltage range) volts of the no-load voltage. The waveforms shall still appear clean on
the oscilloscope and have less than 1% distortion.
11)
Program the Current Limit to 5.0 amps:
8 ENT
5 PRG ENT
12)
The display should show the error message 'AMP ABC FAULT' for a 3-phase system. The error
message may not, however, include all of the phases. The output will default to a programmed value
of 5.0 volts with the output relays open.
2.8
REAR PANEL DIP SWITCH (SW1)
The rear panel Dip Switch is used only for the output phase configuration in high power multi-chassis systems.
The following product/system configurations must have the DIP switches set to the logic "1", or OFF position.
a.)
All single chassis systems
b.)
All chassis with the Oscillator/Controller installed.
c.)
All chassis in systems with the MODE option installed.
