Cause
Vario function of the Vario pedals
(GN 323, GN 325) is not supported in
autoCOAG mode – bipolar
Dosage monitoring (voltage) —
monopolar
Dosage monitoring (current) —
monopolar
Dosage monitoring (HF-on) —
monopolar
Criteria for automatic HF deactivation
not achieved (time exceeded)
Allowable temperature exceeded at
monopolar end stage
Maximum allowable HF activation time
exceeded – monopolar
Two keys pressed on handle — monopo-
lar
Plug put in false socket — monopolar
Dosage monitoring (voltage) — bipolar
Dosage monitoring (current) — bipolar
Dosage monitoring (HF-on) — bipolar
Criteria for automatic HF deactivation
not achieved (time exceeded)
Incorrect output impedance — bipolar
Maximum allowable HF activation
duration exceeded — bipolar
Two keys pressed on handle —
bipolar
Faulty communication — CAN
Remedy
Error message is issued only at the first
actuation of the pedal. After that, the
Vario pedals (GN 323, GN 325) behave
like the dual pedals (GK 223, GK 324),
i. e. the HF output operates at 100 %
power both in CUT mode and in COAG
mode
