Warning and Fault States – Error Conditions
Figure 15. User Terminates Energy Cycle – Generator Returns to “User
Request” State
When user presses
RF ON/OFF button
to terminate RF transmission, generator returns
to the POWER CONTROL MODE
User Request State
and
“RF ON/OFF”
LED turns
off.
“User Request” message is displayed in the upper right.
Both device and indifferent, dispersive electrode remain connected.
Parameters display for 3 seconds then reset to preset values.
Final Impedance
measured (90 Ω) is displayed and graphed against baseline value
(100 Ω).
Final Percent
change in impedance is displayed (e.g.
↓
10%).
Final Power
transmitted is shown on the left (50 W).
Time at User Termination of RF energy
is displayed (41 s).
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 16. Generator Enters “Diagnostic Evaluation Mode”
To enter the
Diagnostic Mode
from the POWER CONTROL - Ready State, user
presses the
MODE
button.
RF energy is inactive and the “RF ON/OFF” LED is off.
User connects an accessory device (not yet available), presses “RF ON/OFF” to set the
baseline resistivity
value.
Measured resistivity
(300 Ω/cm) is displayed and graphed against baseline (250
Ω/cm).
Final Percent change in resistivity
is displayed (
↑
20% indicating an increase).
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.
