When the element temperature becomes 80˚C MIN, in the PM driver, heat protective alarm circuit for the internal
elements is activated and this LED illuminates.As the alarm circuit is activated, the operating current is shut and the
stepping motor becomes in a de-excited state. Simultaneously, the alarm output relay is closed to generate the output
signal. When the element temperature falls back to 80˚C MAX, the alarm is automatically released and the current flows
into the stepping motor. When the alarm is ON, turn the main power OFF before the automatic recovery system works,
and take measures to reduce heat generation such as forced cooling to the PM driver enclosure
