inoperative. This fault can be triggered by an internal system failure or
by operating the ESU outside its safe operating conditions (ambient
temperature too high or too low, etc.).

Possible Causes of RF Power Delivery Interruption
RF power delivery can cease due to operating conditions other than user
intervention. RF power automatically ceases when:
•
The ESU detects a current of 1.1 Amps or more in either of the two
DIP Electrode connectors.
•
Impedance is less than 25 Ω.
•
Impedance is greater than 300 Ω for more than 10 seconds.
•
Temperature of a non-selected electrode exceeds 70° C for more
than 1 second.
•
The ESU detects a current of 0.9 Amps or more in any Probe
electrode for more than 3 seconds.
•
Temperature of an electrode exceeds 120° C for more than 1
second.
•
Temperature of the hottest electrode exceeds the temperature of
the coolest electrode by more than 15° C for more than 5 seconds.
