Warning and Fault States – Error Conditions
Figure 17. ERROR "Imp Limit" – Impedance Exceeds Threshold
This error (warning) occurs when Impedance exceeds the threshold limit, causing
termination of RF energy transmission.
"Imp Limit" message displays in upper right and Error LED illuminates.
For warnings, parameters display for 3 seconds or until the warning is corrected. Once
the warning is corrected then the parameters reset to the preset values.
Final Impedance (765 Ω) is displayed and graphed against the baseline (100 Ω).
Final Percent change in impedance is displayed (↑ 665%).
Final Power transmitted shown (50 W).
Time at User Termination of RF energy (34 s) displayed.
When this warning occurs, an audible tone will sound three times for 1.5 seconds with
450 milliseconds between tones
Figure 18. ERROR "RF Eff Limit" – System Error
This error (fault) occurs when there is a conflict with hardware or software, causing
termination of RF energy transmission.
All faults that are not recoverable will be displayed with the appropriate message and will
require cycling of the main power switch so the generator passes through self-test.
"RF Eff Limit" message is displayed and the Error LED illuminates. (Eff = Efficiency).
Parameters display until the generator is Powered OFF, then Powered ON so that the
generator performs its start-up diagnostic self tests.
Final Impedance (90 Ω) displays and is graphed against baseline (100 Ω).
Final Percent change in impedance is displayed (e.g. ↓ 10%).
Final Power transmitted is shown (50 W).
Time at User Termination of RF energy (22 s) is displayed.
When this fault occurs, an audible tone will sound continuously until the generator is
turned off.
