Pforw. at limit!
This warning occurs in external (DC bias) regulation
mode when the forward power required to reach the DC
bias set point is higher than the user-set limit. The unit
has reduced forward power to remain within the limits.
Output is not at set point.
Cause: The plasma did not ignite.
Solutions:
• Increase the forward power limit. You can set this limit
through the
Host
port command 4 (see
) or through the front panel (see
External Power Regulation Mode (DC Bias)” on
page 5-14
).
• Change plasma conditions.

Output is not at set point.
Causes:
•
VSWR is too high
•
Cooling water is too conductive
Solutions:
•
Reduce VSWR
•
Make sure that cooling water is within specifications
