SECTION 4
OPERATION
29
4.1.1 OVERVIEW (continued)
NOTE:
The five dark-colored keys in the lower right portion of the keyboard are executive keys. Every
attempt has been made to ensure that in order to change power applied to the load, one of these keys must
be pressed. This operational feature has been designed to help keep the user from accidentally pressing
the wrong key and unintentionally changing power to the load.
IMPORTANT! Pressing a BLACK key will probably cause a change in the output power.
4.1.2 BASIC OPERATION
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, which also allows
you to setup transient events. Programming and executing a stored program is described in (
respectively. For a list of individual functions, see the
HOW TO... FRONT PANEL REFERENCE
at page v
of this manual.
QUICK MANUAL MODE OPERATION
NOTE: OBSERVE ALL SAFETY WARNINGS AND CAUTIONS LISTED AT THE START OF THIS
MANUAL !!!
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 then
perform one of the following steps:
A.
Enter a numeric value on the keyboard 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 then perform one of the
following steps:
A.
Enter a numeric value on the keyboard 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.
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.
NOTE: To ensure operator safety, ALWAYS check any terminals for voltage before
connecting or disconnecting any attached wires.
