Press the start switch and advance the voltage control one turn clockwise. Increase the current
set point to maximum and then to minimum. The power and current control indicators should
light. Dc current should increase smoothly from minimum to maximum to minimum as
indicated on the meter. Return the current control full counterclockwise. Press the stop switch.
To check over current trip, press the menu key and the item key three times. This places the
power supply in data entry mode to set over current trip. Using the keypad, enter an over current
trip set point at half the rating of the power supply. Once the over current trip setting has been
entered, press the enter key to save the information.
Press the start switch and slowly increase the current set point. Over current trip should operate
at the over current trip set point. The over current trip (OCT) indicator should turn on, the power
and current control indicators should turn off, and the supply should shut down. Press the clear
key. Now set the over current trip set point to maximum which is 110% the full scale rating of
the power supply. Because the over current trip set point was the last keypad command, data can
simply be entered, eliminating the key presses of menu and item. With the maximum over
current trip set point entered, again start the supply and observe that the power supply operates
normally.
If any of these events do not occur, the supply is defective and should not be operated.
Depending on the circumstances, either warranty service or trouble shooting, as described in
Section 7.2, is required.
2.6.2.2 DPA Series Models
With the power supply off, disconnect the load, set voltage and current potentiometer controls
full counterclockwise, and set the over voltage trip and over current trip potentiometer controls
full clockwise. Connect the power supply to a suitable source of ac voltage. (For this test, only
50% of rated ac current is required.) Turn the power switch on and observe the indicator lights
going through the startup routine. After initialization, the following indicator lights should be
on: standby, int ctl, ext ctl, and rotary. This is the default configuration from the factory. It is
recommended that the following brief electrical check be made shortly after unpacking the
supply.
Press the start switch and advance the current control one turn clockwise. The power and
voltage control indicators should light. Increase the voltage set point to maximum and then to
minimum. Dc voltage should increase smoothly from minimum to maximum to minimum as
indicated on the meter. Return the voltage control full counterclockwise. Press the stop switch.
To check over voltage trip, press the trip dis key on the front panel and set the over voltage trip
potentiometer to half the voltage rating of the supply. While the trip dis key is pressed, the
voltmeter and ammeter displays the over voltage trip and over current trip settings.
Press the start switch and slowly increase the voltage set point. Over voltage trip should operate
