Indicates insufficient current in the rotor boost state.

DRGEM high-frequency generators typically require a stable, high-capacity power supply. The manual specifies the exact line voltage (usually 3-phase 380V/400V/480V or single-phase 220V depending on the kW rating) and line impedance limits. High line impedance can cause voltage drops during exposure, leading to system errors or aborted exposures. Mechanical Alignment

Tube head drifts or is difficult to move. Solution per service manual:

: The generator did not receive the "Ready" signal from the stator board indicating the anode is spinning at full speed. Check the stator cable continuity and the phase-shift capacitors on the stator board.
