power). For more information, see the literature section on our web site at
www.advanced-energy.com. Look for the document titled, “Forward and
Reflected Powers. What do they really mean?”
To verify that your reflected power is high, use the Display Mode button on the front
panel to cycle through the display modes and monitor the reflected power reading. If
you have high reflected power:
1. Use the Display Mode button on the front panel to cycle through the display
modes until the frequency range is displayed. Determine if the frequency band
that the generator is set to is appropriate for your use. (To set the frequency band,
see
“Setting the Frequency Band” on page 5-11 .)
2. If the reflected power reading is close to 1000 W, the troubleshooting steps are the
same as those outlined in “At Set Point Indicator Off” on page 6-7 .
Note: The reflected power is limited by the HFV generator to 1000 W internally.
It is most likely that your HFV generator is functioning properly and is
reacting to an external condition.
3. If the reflected power reading is much less than 1000 W, see “Running Internal
Diagnostics” on page 5-18 .
There could be an internal failure in the power or measurement section of the
HFV generator. The Internal Diagnostics is a self-test that will verify the
integrity of these sections of the supply.
