681.x Hardware enable missing
Description
Induction oven generator
When the output stage is activated at least one enabling signal is missing (EN1 to GND1 and/or EN2 to GND2)
If the error display is flashing, the fault is for output stage 2 (output X2), if the error display is stationary, for output stage 1 (output X1).
The seven-segment display of the inductor indicates an 'e'.
Remedy
Check that an adequately high (>20 V) enabling signal is present between corresponding enabling input (EN?) and GND (GND?).
ATTENTION: The enabling signal is applied by the control only shortly before activation of the output stage.
