Gmr32b Phase: Controller Manual

She pressed.

: Rotating phase lag on L2. Internal thyristor driver overheating. Do not reset. Do not power cycle. Solution: Manual phase rotation via rear-panel DIP switches, followed by a soft calibration (see p. 41). gmr32b phase controller manual

: Red LED indicating a phase failure or incorrect sequence. She pressed
