Power modules
The operation is conducted from the front:
When the power is turned on, all the LEDs on the power module
light up for 4 seconds. The "TEMPERATURE" LED
fl
ashes during
this time.
Power module handle:
Signals on the power module
"CONTROL"
(green)
Lights up when the target power is reached.
Flickering indicates a minor, momentary deviation that is not
an error.
"TEMPERATURE"
(red)
Flashes if the power is reduced due to excessively high
temperatures inside the generator.
"TRANSDUCER"
(red)
Lights up permanently in the case of a short circuit.
(Defective transducer or feed cable).
Flashes 1× per second during idle motion; the "CONTROL"
LED may
fl
ash simultaneously.
Flashes quickly or
fl
ickers if HF current or HF voltage is too
high.
"DRY"
(red)
Lights up if the reactive power is too high
(generally when running dry or if transducer is incorrectly
adjusted).
Flickers once the limit state for running dry is attained.
"ACTIVE"
(green)
The switch is used to individually switch off the module in
operation.
The LED for the switch is lit green when the switch is pressed
and indicates that the module is ready for operation.
