4.1.2 QUICKLY PUTTING THE UNIT TO USE
The following steps provide a quick method (using MANUAL MODE) for setting Voltage and Frequency
and applying power to a load. To set other parameters, such as phase angle, waveform, current limit,
power form and output coupling mode (transformer or direct), use the PROGRAM EDIT MODE. It also
allows you to setup transient events. Programming and executing a stored program is described in
sections 4.5 and 4.4 respectively. For a list of individual functions, see the
HOW TO
reference in the
beginning of this manual.
QUICK MANUAL MODE OPERATION
1.
DO NOT CONNECT A LOAD
to the power source until you are satisfied that the power source
output is appropriate for the load.
2.
Be certain that the
OUTPUT POWER SWITCH
is
OFF
. Then apply input power to the UPC or
power source using its INPUT POWER SWITCH. Allow a few seconds for the UPC to initialize.
It will beep twice when it is ready.
3.
The V/I METER will appear. This is the default display. It shows metered Volts and Amps (AC
RMS). It also shows the Voltage and Frequency entries in the upper right corner of the display
as the user is entering or changing them.
4.
TO CHANGE VOLTAGE - Light the
Va
,
Vb
and/or
Vc
LEDs by pressing the keys below them.
Now perform one of the following steps:
A.
Enter a numeric value on the keypad and press
EXECUTE
. - or -
B.
Press the UP or DOWN arrows (
︿
or
﹀
) to 'slew' the voltage.
The phases that are indicated by the V LEDs will be changed to the voltage selected.
5.
TO CHANGE FREQUENCY - Light the
F
LED by pressing the F key. Now perform one of the
following steps:
A.
Enter a numeric value on the keypad and press
EXECUTE
- or-
B.
Press the UP or DOWN arrows to 'slew' the frequency.
NOTE:
You cannot change Voltage and Frequency simultaneously using MANUAL MODE.
NOTE: OBSERVE ALL SAFETY WARNINGS AND CAUTIONS LISTED AT THE START OF
THIS MANUAL !!!
6.
TO CLOSE THE OUTPUT RELAY - First move the
OUTPUT POWER
switch on the power
source front panel to the ON/AUTO position. Then press the
OUTPUT ENABLE
key on the
UPC keyboard. Verify the power source output (rear panel output terminals) is generating the
desired voltage, frequency and phase angle using an oscilloscope and/or meters.
7.
TO APPLY POWER TO THE LOAD,
TURN OFF the OUTPUT POWER
switch and
TURN OFF
the INPUT POWER
switch. Connect the load to the rear panel output terminals. Switch ON the
INPUT POWER switch, switch ON the OUTPUT POWER switch. Then press the
OUTPUT
ENABLE
key on the UPC (controller). Power is now being applied to the load.
