microBrute DRSSTC Instruction Manual
18. Ensure that you are standing at least five feet from the microBrute DRSSTC
and plug in the Resonator Control Power Cord.
19. Slowly begin increasing the pulsewidth (PW) of the microBrute handheld
controller.
DO NOT EXCEED 50% PW at this time.
One of two things are
going to occur.
NO OUTPUT – Feedback polarity is reversed.
OUTPUT – Feedback polarity is correct.
In either case, determine which is occurring and unplug the Resonator Power AC
power cord immediately. Turn OFF handheld controller and reset pulsewidth
(PW) to 0.
20. If NO OUTPUT was detected, simply reverse the polarity of the primary
wire connected to the OUT- terminal on the PC board. This is done by simply
reversing the direction that the primary wire enters and exits both current
transformers as is shown in the figures below:
Reverse the polarity as shown above, and repeat Steps 15-19. If no output is
detected even after reversing the polarity, then there is another issue which needs
to be debugged and corrected.
21. If OUTPUT was detected, you are in good shape. Continue increasing the
pulsewidth, using the handheld controller up to 75%. You will notice that the red
OVERCURRENT LED should illuminate and limit the arc output to almost
nothing. This is normal as the current limit has been intentionally set low to test
its operation. If the OVERCURRENT LED does not illuminate, re-verify that the
proper voltage measured across capacitor, C25, as performed in Step 13, is
correct. If the voltage across C25 is correct and the OVERCURRENT LED does
not illuminate, than there is another issues that requires to be debugged and
