4. After mak
ing all of the connections, set the PA3000 to the default
configuration:
a. Press
.
b. Scroll down to User Configuration and press
.
c. Select Load Default Configuration, and then press
to confirm.
The PA3000 will load the defaults and display a confirmation screen. Press
and then return to the Main Menu by pressing .
5. To select the correct wiring configuration within the Main Menu, go to Inputs
→ Wiring → Configuration and select 1 Phase 2 Wire for Group A.
6. Scroll to Group B by pressing the arrow key on the left front panel and select
3Phase4Wire.
NOTE. If desired, both groups can be named for ease of monitoring. Go back one
step and enter the appropriate name using the Group Name option.
7. The PA3000 makes it easy to configure important settings using default
modes. For the PWM motor drive output, from the Main Menu by select
Modes → Select Mode → PWM Motor.
The PWM Mode will set up the PA3000 to accurately measure the output
voltage of a typical PWM drive that switches at high frequencies. The
a
lgorithm applies a proprietary sensing method to determine the actual
fundamental power frequency in real time for all pow er calculations so that
the calc ulated power and harmonic data are always accurate even in dynamic
speed conditions.
